What is the Better Buildings Ottawa Strategy?

The Better Buildings Ottawa Strategy was approved by City Council in October 2021. This strategy identifies how to encourage and support deep greenhouse gas reducing retrofits in commercial, institutional, and industrial buildings as well as large multi-unit residential buildings (MURBs). This includes all buildings in Part 3 of the Ontario Building Code, excluding those owned or operated by the City since they are dealt with under a separate Municipal Building Retrofit strategy.

The Better Buildings Ottawa Strategy is made up of several key components.

City Council has directed the development of energy disclosure and performance bylaws. This is following a similar course of direction to Vancouver in 2019 and Toronto in 2020. The Better Buildings Ottawa Strategy will seek to prepare building operators for these regulatory changes and support them in undertaking energy efficiency measures in a cost-effective manner.

Why is building energy efficiency important?

Existing buildings are the single biggest source of greenhouse gas emissions in Ottawa. In 2020, industrial, commercial, and institutional buildings contributed 22 per cent of Ottawa’s greenhouse gas emissions. Most of these emissions are from space heating.

To meet our target to reduce greenhouse gas emissions to zero by 2050, 95 per cent of commercial and industrial, as well as large residential buildings, must reduce energy for heating use by 70 per cent and for electricity use by 30 per cent by 2040.

An energy-efficient building is healthier to work or live in, more valuable, more resilient and reduces money spent on energy, and energy used. Building energy retrofits also create good, local, green jobs. A study by Toronto-based non-profit The Atmospheric Fund (TAF) also found that energy-efficient buildings have lower tenant turnover and vacancy rates, increased property value, and reduced insurance cost premiums.

A 2023 report by the Building Decarbonization Alliance, of which the City of Ottawa is a member, focuses on the business case for electrifying buildings. “The Case for Building Electrification in Canada” puts forward the opportunities for building owners to replace their existing fossil fuel infrastructure and equipment with electric alternatives. The full report can be found on the Building Decarbonization Alliance website.

Retrofit Financing Options

Deep Retrofit Financing Options

The City of Ottawa has identified several retrofit financing options available today which may serve building owners and operators looking to undertake deep energy retrofits. The City has no official ties or associations with any of these financiers.

Interactive map – Open-loop geothermal resource potential

In 2021, the City worked with J.L. Richards and Associates to perform a preliminary study of the open-loop geothermal resource potential within Ottawa. 

It is important to note that this study only looked at open-loop geothermal resource potential. Most areas in Ottawa have a strong closed-loop geothermal resource potential.

The interactive map shows the open-loop geothermal resource potential within Ottawa.

Webinar series

Insights Report Webinar - With Poll Results

So everyone, my name is Marie.

I'm a project manager at the City of Ottawa's Climate Change Mitigation and Resiliency team, and I focus on supporting building owners and managers in Ottawa with their energy and decarbonization objectives by running a benchmarking program with perks.

So today we have with us Daniel Eden from Open Tech who supports that benchmarking program with the public disclosure mapping tool as well at which has some new exciting features coming out very soon that everyone will get to see.

And also that group provides us with the free insights reports for every building that participates and discloses their performance data with the City of Ottawa.

So these insights reports are provided to all better building Ottawa participants as one of the program perks.

And today we get to have a deep dive into how they're created and how they're being used.

This is our first webinar, so I'm just going to take a second and see if I can get all of my functions working.

But while I do that, Suzanne, do you mind launching the first poll just to get a sense of who's in the room?

So the question is, have you or your organization participated in better buildings Ottawa yet?

And I know not everyone here is in Ottawa has buildings in the port or portfolio to work on.

So far, that's everyone who's here has answered.

Sorry, Suzanne, I can't hear you.

Sorry, can you hear me now?

Yes, I said so far, everyone's answered now.

So that's great.

Thanks so much.

So the majority is not really our current participants in the program.

It's great to see that their interest from beyond as to how they could be implementing a solution like this.

Thanks so much.

Suzanne, you want to stop the sharing of that?


And let's see.

Can you see my presentation screen?

Thank you.

All right.

Wait, so I think we see your notes right now.


How about now?

Is this better?

It is still your notes.

Thanks for hanging on.

While we go through our first round, how about now?

Does it say Poll #2?

So the second question we had for the group was really for those of you who participated in the Better Buildings program in the past, have you seen your Insights report?

I'm hoping that it didn't go to the wrong person, so please let me know.

And no need to answer, not applicable.

If it's not you, great.

I'm glad that there's nobody here saying they wanted an insights report and it hasn't arrived in their inbox yet.

That's great to see.

Thanks so much, Suzanne.

We can go to our next one, which is really for those that those small few, how valuable it was.

And perhaps instead of answering a poll, you could just put some information in the chat to provide a little bit of feedback so we can keep our promise of 30 minutes or less.

So without further ado, I'd like to pass it over to Daniel, who is kind enough to, well, it's wonderful to work with Open Tech and Daniel specifically.

And thanks so much for giving us a walkthrough today of the Insights report.

You bet.

Thank you so much for having me.

Hi, everybody.

My name is Daniel Eden.

I'll be asking Marie to switch through the slides too.

So Marie, can you go to the next slide, please?

Working on it, yes.

So yeah, I mean, why?

Why am I here?

Why are you listening to me?

Well, I'm a professional engineer.

I have 10 years of experience doing engineering consulting, specifically in the green building space.

So looking at energy audits and green building certifications as well as capital planning.

I've also been an adjunct professor at the University of British Columbia, you know, delivering a course specifically on building energy systems.

But for the last few years, I've been working in software as the product manager for GRID.

And GRID is a tool that we've built to help deliver and support benchmarking programs and create these insight reports.

So let's go to the next slide.

So what am I going to be talking about today?

Well, I'm going to give you an overview of these scorecards or these insight reports.

I'm going to dive a little bit deeper into the methodology.

So specifically looking at you know how we're doing weather normalization, how that leads to end use breakdowns.

And finally I'm going to focus on you know the now what, what are the targets and recommendations that flow out of these.

And you know, as Marie mentioned at the beginning, we're really looking for feedback and your questions.

If anything's not clear, please feel free to add that to the chat and we'll circle back to it at the end.

Let's go to the next slide.

You know, I'll be talking a lot about energy use intensity EUI and greenhouse gas intensity GHGI.

So before we go any further, I think there's one last poll here just to see how familiar everybody is with those terms.

All right, a few more are gonna add their results here.

I think that's pretty good.

Let's see.

See the final what's happening?

It's 73% are answering yes, they know, which means 27% are Now saying that you're not familiar with that.

You can see those results.


All right, so most people are familiar with it.

But for those who aren't Marie, can you click through the next few animations here?

I mean, intensity simply means dividing the the energy use or the greenhouse gas use by the gross floor area.

So if you have two buildings like this, one small one and one big one, and they have the same energy use.

So let's reveal a few more things here.

So for example, they're both using 15,000 gigajoules of energy, but they have a very different gross floor area.

If you take the energy use and divide it by the gross floor area, you'll see that they have a very different energy use intensity.

The building on the right has actually a better energy use intensity, so it would be considered the higher performer in this case.

So let's go to the next slide.

All right, So enough of an intro, Let's get into the scorecards.

So the scorecards basically look like this.

There's three key sections.

The first one is focusing on your annual results for the, the year in question, the year that was being analyzed.

The second section looks at your monthly results.

So this is really where we kind of get into the juicy stuff.

And then the third section kind of takes all of that and says, well, now what?

What are the recommendations?

What can you do from there?

All right, let's jump into the first section, the annual results.

So the first page of your insight report looks like this.

And at the very top.

So Marie, if you can click through three times here, the very top has your basic building information.

So in there, we're seeing what kind of property type have you been classified as.

That's really important because that's the peer group that you're being compared against for the rest of these scorecards.

And we're also showing here at the top your gross floor area.

So that's also very important because we saw that the gross floor area is used to calculate the intensity metrics which are used throughout the second part of the scorecard are your highlights.

So this shows your rankings against basically the other buildings of the of your peer group for that year.

And obviously as the program grows, those insights and those rankings are going to become more and more valuable to you.

So we can see here there's fifty other office buildings and those highlights we're showing, we're kind of bubbling up what your trend is for greenhouse gas intensity.

So this building has an increase of 13% of their GHGI.

And then we could also see your rankings against the rest of the group.

So they're six out of 50th here for office buildings and 24th out of 333 for the whole cohort of buildings.

Those highlights are focusing specifically on greenhouse gas emissions because we know that greenhouse gas emissions are the main contributor to climate change.

The third part of this annual results are your year over year results, so essentially comparing your building to itself throughout the years.

So each column here is a different year in that table and each row is a different performance metric and the last column is basically showing you your trend from one year to the next.

So if we look at the 3rd row, for example the site UI, we can see that in 2021 the performance is 166.7 equivalent kilowatt hours per meter squared.

And just below that, I don't know if you can see my mouse, but just below the 167 point 66.7 we can see your percentile too.

So your percentile is showing your ranking against the rest of the the office buildings in Ottawa.

And this building is 90 in the 90th percentile and here a the 100th percentile is the best performer.

So this is a very, you know, good, performant, high performing building.

All right.

Let's go to the next slide.

You know, the second page of the scorecards are showing your annual results, but more in a visual format.

So again here each of these histograms is showing one performance metric.

So the first one here is your greenhouse gas intensity.

We can see that you're, you know, in sixth position out of 50.

That second bubble is highlighting the histogram itself.

So you know it goes from red, which is bad, to blue, which is a good performer.

So we can see here for energy use intensity, most of the buildings are kind of clustered around about 200 equivalent kilowatt hours per square foot.

And then there's a tall black bar in each of these crafts, and that is the performance of your building.

So in this case, your building is performing slightly better than the majority of buildings for energy use intensity.

And let's go to the next slide.

So that's just showing kind of where your performance is compared to the rest of the peer group, all right.

So the monthly results, this is kind of getting into the, the juicier section of the scorecards.

So Marie, if you click once through here, we'll see the top part of the scorecard is showing your monthly performance for the last three years.

If we have three years of data for your building and it's showing basically the the darker bar, it's showing this by energy type.

So on the left we have energy use intensity, sorry energy, electricity use and on the right we have thermal energy usage and thermal energy usage is combining all of the fossil fuel based energy types.

And so one thing that's important to note here is that you know if you're comparing one year of energy consumption to the next, it's not a fair comparison if the weather was different each year.

So what we've done is a weather normalization essentially trying to take weather out of the equation.

And the way we do that is for each year we compare the your energy consumption compared to the weather of that year.

And if there's a strong correlation between energy and weather, then we can use that.

We can basically pull out an equation to predict your energy based on weather.

We do that for each year and then that captures the behavior of that year and we can then plug in the 30 year average weather for each year.

So it's basically giving the same weather to each year.

Like I said, taking weather out of the equation in a sense.

If you click once again, we can see here also on the graphs we put in the average performance band.

So for this particular building, we can see for electricity, they're basically kind of in the average, maybe slightly on the lower end of the average.

And for thermal energy use the graph on the top right, we can see that this building is performing slightly better than average.

All right.

So let's click once more.

So the bottom half of this page is showing you now the energy use breakdown by energy type.

And the reason we can do that is because we found that correlation between energy consumption and outdoor weather.

And so if we look at the bottom left graph, we're looking at the electricity breakdown.

We can pull out what part of your electricity, your monthly electricity consumption is probably used for heating and what part is used for cooling and what part can be attributed to a base load, So a consistent load throughout the year.

We do that for both electricity and for therm water to use.

That's good.

You can go to the next slide.

Thanks, Marie.

So I also wanted to show you comparison, because for some of you there may not be a correlation between energies and weather that happens as well.

So let's click one more time and you'll see here on the right hand side a second scorecard where there was no correlation.

So if you click once more, we'll see here.

When there is no correlation in the title of the graph, we'll just say that we're presenting your build value, so basically your your raw utility consumption data.

And if you click once more, we'll see on the bottom.

Since we weren't able to pull out a strong enough correlation between weather and energy use, we're just showing all of your energy as the base load.

All right, so let's go to the next page.

What this energy use breakdown allows us to do is then take your greenhouse gas intensity and break that down into the end uses.

So on the graph here on the left hand side, so if you click once more we can see this is your building's performance, your greenhouse gas intensity performance for broken down by the different end uses.

On the right side of the building is the average building type.

Eventually what we want to include on this graph too is 1/3 column that would show what is the net zero energy or the net 0 consumption building and how do you compare to that as well.

And if you click once more, we'll see that, well, where do these colors come from?

They come from that energies breakdown that we did on the previous page.

So if you click through a few times, we'll see that, you know, the colors relate here.

The the teal is the teal, the blue is the blue, the orange is the orange.

And for this particular building, most of their greenhouse gas intensity comes from thermal energy heating.

And that's the case for a lot of buildings.

All right, let's go to the next slide.

Finally, we move on to the recommendation.

So what do we have here?

You'll see that we essentially take those N uses again and we compare each N use to the rest of your peer group.

So if you click through once more, so here we have your heating energy.

This combines heating energy from electricity and from thermal energy usage.

And we're showing your percentile ranking.

So 100 percentile is the best building.

This building is 86 percentile.

So it's doing very, very well.

And just below that, we also set a target.

So if you click once more, if your building is below the 75th percentile, well we're going to give you the 75th percentile as your target if your building is above the 75th percentile.

So as is the case here, we say well what if you also had a 10% improvement over that and then we show what it would be the impact of achieving that target in terms of reducing your greenhouse gas emissions.

So here there would be a reduction of 3.84 tons and also what would be your energy cost savings.

So here it's roughly $3500 per year.

And so we're trying to provide a bit of intensive here of like you know what would, what would the world look like if you did kind of achieve the the cream of the crop in terms of performance.

I think you can click through a couple more times.

So once again, I'm just showing here that you know, these results are coming from the energy use breakdown that we did at the monthly energy performance level, All right.

So the last page here is now looking at, well, what do we do with all of this information, A couple things here.

So the first one, if you click once more, we'll see that some of the scorecards, some of the insight reports actually also include thermal image scans.

So Marisa I think is going to talk a little bit more about why some buildings have this.

It's it's a pilot program that the city is running.

If you click again we'll see also for the main building archetypes, for example office buildings, multi unit residential, the City of Ottawa worked with WSP to develop retrofit Rd.

maps for those building types.

So if that's applicable, applicable for your building type, it's going to be linked here.

And finally, we also encourage everybody to, you know, register for the next year of the program.

So I think that's all I had from my end.

Obviously very open to any questions that you have.

And yeah, thank you for your attention.

So are there any questions?

Let's take a look at the chat and see if there were any specific questions on that.

Daniel, there was a question on the GHG breakdown graph.

Is the average building in Ottawa specifically or Canada?

It's an Ottawa specifically, it's looking at the average building of the same building type.

So it's looking at your peer group.


And the next question was on the monthly performance graphs.

Is the Gray band for the building being reported on or for all buildings in this type?

There's a great band for the building being reported on?

Oh yeah, OK.

It's for all buildings of that type.

So if you're an office building, it's showing you the average performance band for office buildings in Ottawa.


That's it for questions that I see right now.

There is one more, I'm sorry, in the Q&A is the data drawn from ESPM.

So the data originally comes from Energy Star Portfolio Manager and is shared with an account that the City of Ottawa has a better buildings Ottawa account and that feeds grid seed and all of this information.

So it's the exact same data that gets input into Energy Star Portfolio Manager.

That is the key data source that we're using for this analysis, Yes.

Harry Harry's next question is, so no other data sources and I'd have to think really hard to see if there are any other data sources that are being pulled in.

There are for other parts of the analysis.

But Daniel, is there anything else in order to produce the these map, these insight reports?

Rather, yeah.

The insight reports come purely of comparing the energy that's flowing from Energy Star Portfolio Manager.

So it's all of the energy data that the participants in the program are reporting.

We're not pulling any of the Canadian wide averages or anything like that.

It's all just compared to the the data that's being reported as part of the Better Buildings Auto program, right.

But Harry, some of those additional elements like the thermal imaging scan that doesn't come from Energy Star Portfolio Manager and WSP specific Architect reports on 0 carbon pathways with costing that's also a separate piece of information.

And one more question back in the chat, was there a process in place for excluding data points that were considered to be incorrect, like consumptions of 0 or unusually high consumption values, Dan?


So one of the features that we've built into GRID, which is the tool that helps to generate these reports is that it flags any incomplete data or it flags any unusually high or low consumption data.

And then it allows the the program manager, in this case the City of Ottawa to mark those buildings as incomplete or invalid and they don't get included in the analysis at that point.

Absolutely, yeah.

And we do find frequently actually there was just a case earlier this week of a large portfolio owner that submitted their data to us and we went through that kind of high level quality check and found that the information they were submitting and other sources was incomplete and inaccurate.

And so we were working with them to correct that so that we can have a fulsome set of accurate data in our benchmarking program.

Can you still see my slide?

Because I want it with six minutes left and I'm committed to the 30 minute mark.

And so I just wanted to be clear that the Insight reports are really just one of the many growing Perks that we're offering in our program.

I'm constantly listening to our current and potential future stakeholders to hear what would be enticing for participation in the program or what their current struggles are in terms of, you know, engaging in further action on decarbonization or access to data.

So I'm listening to that and that's how we're developing our list of perks.

So Insights report is 1.

Also, we have access to free training, so participants in our program get access to sessions like energy efficiency for building operators is one that we've run.

We ran another one of making the case for decarbonization projects.

We're going to continue running the energy efficiency for building operators.

I was such a valuable workshop and the building operators are really a key stakeholder in moving all of this forward.

And how I like to divide this sometimes is the difference between investment projects on capital and investing in in people and operational changes, getting better checklists, policies, procedures, recommissioning of buildings.

So they're in two different categories in my mind all the time.

We also are offering any current participants discounts on a number of services.

One is the thermal images.

So if your property didn't have a beautiful thermal image to give a sense of how much energy leakage there is from the building envelope, feel free to participate in the program or ask me questions about how to get access to those those discounts, standardizing information, additional training programs.

We've just launched our webinar series and are open to feedback on how, what additional topics we should have moving forward.

Retrofit financing programs is another perk.

So there's right now a call for expression of interest any building that's multi unit residential to that condos or apartments that are large.

So part three of the Part 3, but there is funding right now specifically for Ottawa, a limited time offer.

So please do throw your hat in the race, just send me an e-mail after this and I'll send you the link.

It's about 10 questions to potentially receive funding for all incremental elements of replacing your mechanical equipment and getting off of majority natural gas and having a major reduction in GHG emissions and more are being added on a regular basis.

So please feel free to let me know what else you'd like to see from the program.

If you're already participating in EWRB, then what we like to say is this is about 10 to 15 minutes of additional work for that laundry list of perks and programs as which is always growing and is here to meet your needs.

And if you're not already in EWRB participants, we can help.

Just send us an e-mail and we can help get you started on that path.

Our next webinar is planning to be on the state of building envelopes in Ottawa.

So it's going to be the high level results from the pilot project that we ran of having 191 buildings have thermal imaging scans, aerial and from from from street views.

So we'll have the results of that.

So the state of building envelopes in Ottawa.

You can register at this link and if you're missing any of that information, feel free to scan the QR code on the left.

We'll get you signed up for the Better Buildings Ottawa newsletter.

So you hear about all of the UpToDate information that we have launching or the one on the right is the general.

Send us an e-mail saying you were at this webinar and you have additional questions or e-mail better buildings at Ottawa dot CA if you don't have your smartphone handy.

And that's all we have for you today.

I'm just going to double check the chat in Q&A with two minutes to spare.

Oh, I see One more idea of a perk of the program from Houston.

Thank you so much.

I will continue to look into that.

Was there anything else in the Q&A?


Suzanne, do you want to launch the last poll then to get a sense of future webinar topics?

Thanks so much Suzanne.

Ooh, looks like EV charging is of great interest, but also program perks updates.


One minute to spare.

I just want to thank Daniel so much for making the time today for Suzanne for anything, everything in the background for everyone who is able to come today to a 29 minute webinar on your lunch hour or at a different time of the day.

Thanks so much.

It means a lot to me and to all of us as we continue evolving our program.

Have a great day.

Thanks so much.

Thanks, Marie.

Thanks, Suzanne.
Eric Ibey: Suzanne, if you want to start rolling, let's do it.

Suzanne Tewnion: absolutely. so welcome to our second better buildings, Ottawa. Webinars of soon-to-be series, like I said to some of you already. We're going to be doing a 30Â min presentation, and then a 15Â min. Question and answer with Eric.

Suzanne Tewnion: feel free to stay for that. But if you want to enjoy the rest of your lunch also feel free to take off after, as I'm sure you all have the notification, it will be recorded and eventually posted on our web page. So either feel free to look out for that if you want to come back and re-watch it. One important fact of this webinar is that we will be staying on topic today. Any outside chats and irrelevant information in our chats will likely be deleted as we keep going. And last, but not least, I'll pass it off to Eric, as I know he has a lot of talk about

Eric Ibey: for being here. I know lunch hour presentations are not everybody's favorite, so I do appreciate you being here, and I want to be aware of timing like, Suzanne said. I'm gonna try to get this wrapped up about 25 minutes and then I'm happy to stick around for questions.

Eric Ibey: As Suzanne said, we're gonna try to stay on topic. We've got a lot of different people coming from a lot of different, you know, areas and buildings. And so we don't wanna get into the weeds too too much. But if you have to take off for any reason, and you have some questions that weren't answered, and you'd like to add answered, I'm happy to take a conversation offline later. Just so, you know. So my name is Eric Ivy. I am a project manager in the climate change and resiliency Department at the city of Ottawa.

Eric Ibey: My background is, I'm a mechanical engineer, and I've dabbled in few different areas. But mainly I've done Hvac design and energy audits for commercial buildings during my career. So I'm here today to talk about decarbonization and different pathways towards decarbonizing your part. 3 buildings. And the reasons, again, some of these reasons might not be new to you. But we're gonna dig into them. Just a little bit more this present or this, this. The data that you're gonna see in this presentation is from a study we had done from an outside consultant who looked at our building stock?

Eric Ibey: Not specifically. It's it's a very It’s an average representation of different clusters of buildings in Ottawa. So I just wanna kind of caveat before I start that you're gonna see some numbers. It might not be relevant specifically relevant to your building. I'm gonna show you some of the assumptions that were made for the modeling and for the the numbers that you're going to see. But I just wanna everyone to keep in mind that this is a high level average. We're not looking at the worst performers, the best performers. It's really kind of an average. So with that. we got a couple of poll questions. So the first poll question is, what type of part 3 building retrofit are you most interested in just to get an idea of the folks we have. So we have apartment buildings, condos, hotels, office buildings, retail spaces and warehouses, and I believe, can I scroll? I can scroll to?

Eric Ibey: We have institutional buildings, or all the above

Eric Ibey: awesome

Eric Ibey: 10 to 2019. Here we go.

Eric Ibey: Got 2 more. Are those last 2 people gonna participate.

Eric Ibey: 5, 4, 3, 2, one. Alright, Suzanne, let's let's see what we have. Gonna show the results. So 50% condos very interesting, and the other 40% apartment buildings alright.

Eric Ibey: Well, that makes me feel a little bit better, I guess, about the examples that I'm using in the presentation because we are. I use a lot of multi unit residential type buildings for this for this presentation. So that's great. See, we got some office buildings, all of the above interesting, all the above. That's If you said all the above, if you wouldn't mind, just maybe writing in the chat where maybe a little more specificity around all the above. Maybe your portfolio manager. Maybe you're coming from like hydro autoware, something like this. But anyways, we're just curious. But alright! Let me close this Suzanne, or do I? Share results? How do I do this?

PRED EDLRP: I did hit share results. It should have come up but see it, there's there's not okay, cool.

Eric Ibey: alright.

Eric Ibey: So first of all, the building archetypes that we're gonna look at in this study. They were clustered together. So you can see the building types. We have older Merbs, newer Merbs, large mix use institutional, commercial. Not so much industrial. Obviously, auto was not a big industrial town mid size, commercial, small, retail, low rise office and small warehouse.

Eric Ibey: Now you can see that I apologize. It's a little grainy, but the age of the building, and roughly, the size. This is what I'm talking about an average. This is really not, you know, your building might not really fall into that category. Maybe they do. But just to give an idea that when you see some of these numbers, although most of them are on a per square foot or per meter squared basis.

Eric Ibey: those numbers can be affected by a lot of things. As everyone knows, no no 2 buildings are really the same. So just to be aware of that.

Eric Ibey: So these matrices, I'm gonna show you these decarbonization measures matrices. I'm gonna take a moment to to explain, because I know there's a lot going on right there on the left hand side. We have the types of things that you can renovate in your buildings. So the first 3 walls, roof windows you've got envelope, and you've got Hvac delivery in the plant. Domestic hot water, and then the last is solar photovoltaic.

Eric Ibey: Across the top you'll see baseline level, one improvement level, 2 level. 3. Improvement. These are increasing in complexity usually cost, but also decreasing in the amount of you know utilities. You use decreasing greenhouse gas emissions and like, I say, a lot of these might not necessarily pertain to your building, depending on you having hot water, you know. Hot water heating system, a forest air system, but again pretty pretty high level. Along the bottom. You see 6 boxes. These are the different pathways that I'm going to be referring to throughout the presentation. So first, we have like for similar.

00:09:28.790 --> 00:09:36.629
Eric Ibey: So I'm gonna scroll through them. And you're gonna see boxes light up. So for like for similar, you can see that over the baseline. There's only 3 things happening. You're increasing the insulation to your roof. You're improving your windows and doing a little bit of work with your domestic hot water delivery on an easy fuel switch.

Eric Ibey: Little bit more. Not too much. You're just really adding a. The balcony, mounted heat pumps, air source heat pumps, or a central chiller and heat pump fuel switch ready.

Eric Ibey: Now we're getting into more envelope work, improving walls and roof. A little bit more Hvac delivery. We're installing ensuite ervs. Energy recovery ventilators and still no Pv. No photovoltaics in a fuel switch. Only now we're not touching the envelope. But we're just looking at air source heat pump for heating and and domestic hot water, also an air source heat pump.

Eric Ibey: and then for 0 carbon ready. Which is what I, what we're talking about, what we're the goal that this is the end goal. This is where we're trying to go.

Eric Ibey: We have envelope improvements, heating system and cooling system. If it's available improvements. And we're also adding photovoltaics to 50% of the roof area And then we have one level above which is Max site potential. The 3 differences here are, instead of an wall installation. You're going up to our 30. You are also centralizing your Hvac delivery by using a variable airflow Erv system and you're installing a ground source heat pump as opposed to an air source heat pump. So you might ask, well, why isn't that the goal? This seems better. And we're gonna get to that.

Eric Ibey: Let me just go back to that for a second. Are there any questions anything coming up that? Or you? I can just keep rolling. I'm gonna take a sip of water. So if there's anything, come up, feel free to put up your hand, or write something in the chat at any point.

Eric Ibey: Hmm! And Suzanne, if there are questions that come up sometimes I missed them in the chat, if you wouldn't mind just interrupting me. That would be great. Thanks.

Eric Ibey: alright. So let's get into the 7 reasons why we should
upgrade, retrofit our buildings to 0 carbon ready. The first reason is, you are going to make more money part of this study that we had d10, sorry! Go ahead, Susan.

Suzanne Tewnion: There are a couple of questions now coming in. Sure, sure.

Eric Ibey: I guess I can open that up there.

Eric Ibey: So from Houston, Hi, Houston, consider vacuuming solution for increasing well, causing problem there, but I just only wanted to see. But as thank you, that's a that's a great suggestion. I appreciate that your opinion on geothermal heating, cooling. Are you also considering installing ef charging opinions on a lot of things? I don't know if this is getting into the weeds. Geothermal heating, I will say this on the geothermal. It's really dependent on your building sometimes. It's just not possible. That's from sorry. That's from Diana. Thanks for your question, Diana. We can talk about this a little more offline. But I would say it is really, really dependent on your building where you're located.

Eric Ibey: it's not a a solution. I don't think for everybody, but it could be. And it it could be a really great solution if you're if if it's possible. But and if sorry if charging you're referring to.

Eric Ibey: can you specify what what you mean by that? Sorry

Eric Ibey: if you want to turn your mic on I you don't have to turn your camera on. But sorry about that.

Eric Ibey: So ev charging wasn't considered in the study because we're mainly looking at where we can save on greenhouse gas emissions, really building, level, heating, cooling.

Eric Ibey: But yes.

Eric Ibey: this is a huge, huge topic. So again, probably a better conversation offline, and I have a colleague as well specifically works in ev charging, so perhaps I can even point you in his direction. But you can talk about those later. And your great question those effective nominal those are I. I don't. I think they are nominal. They are increasing from, you know, the baseline of 5.

Eric Ibey: That's total total R value if that if that answers your question, I'm gonna keep rolling.

Eric Ibey: So from this Kpmg report that was done for us. We're talking again about making making more money.

Eric Ibey: they found in in studying buildings, specifically multi unit residential and office buildings that the value of the building went up with when it became more efficient. And that's also lease rate. Differential went up as well. So buildings became more attractive to buyers, the tenants.
Eric Ibey: effectively.

Eric Ibey: you know, you can charge more for your building, whether you're selling or renting, II guess, but there is a bit of a caveat to this. I want to be as as transparent as I can. The study did not specify whether that meant that it was based on the high efficiency systems, or if it was based on aesthetics. Usually when a building is renovated even for energy efficiency type. Or, you know, greenhouse gas reducing reducing measures.

Eric Ibey: you improve the aesthetics of the building. And so, where people were the value going up because of aesthetics of both. I would probably argue both. But

Eric Ibey: just to say, too, that if in the future, if there's ever, if very hypothetical, if we have a building rating system. The building rating system would include things like energy efficiency, greenhouse gases. You know your how high your emissions are. So in that case the value would be tied to that rating again. That's in the future, not sure how that's ever gonna be a roll up, but it is being being used in places like Europe, and I believe a few jurisdictions in the United States have started using it as well.

Eric Ibey: So the second thing is, you're gonna save more money, which, of course kind of stands the reason. So to show that we're going to look at energy, use intensity, EU i. Eui, is really the amount of electricity and gas you're using in your building. So obviously, you make your building better. more efficient. You lower your utility uses you save more money.

Eric Ibey: but, as you can see in this chart are along the bottom. On the X-axis we have baseline Lfs is like for similar Fs ready is fuel switch ready. Then we have a like for similar plus fuel switch was, which was kind of that like light fuel switch and then we have 0 carbon ready without without Pv. With Pv. And Max. Site with Opv.

Eric Ibey: With Pv.

Eric Ibey: So you can see that. And our energy evolution target. By the way, energy. Evolution is city of auto strategy. Sort of our action plan to reducing greenhouse gas emissions and getting to net 0 citywide by 2,050, our buildings, the corporations building city buildings. We have a goal of 2,040.

Eric Ibey: Now that target, as you can see, of 87, the closest we come to. It is with 0 carbon ready, and Max site. In all other scenarios we're not saving as much money. So this is a

Eric Ibey: I mean an argument to say that you you'd like to move as close to 0 carbon ready as you can progressively, and you also would like to do it in a way that makes sense.

Eric Ibey: You know, I'm gonna say this now, because I know people are. Gonna ask those questions. You know, what do you do. First, you do the fuel switch. Do you do the envelope?

Eric Ibey: We know realistically, and I know realistically from being in this industry for a number of years. That envelopes are very hard. They're they're expensive, you know. See? A lot of good payback. But that's there's a lot of things that are also happening that I'm gonna talk about late as we move along here. But I think envelope work is becoming more and more attractive because of the changing climate, not climate, weather, but climate of the industry as well, and So I you know they both have to be done envelope and mechanical systems but the order. Of course it always makes more sense

Eric Ibey: in perfect world. We would do our envelopes first, because then we lower our heating and cooling loads on the building, and then you install a smaller heating system than you would otherwise, which

Eric Ibey: I mean saves more money again in capital cost. So, depending on the the order of operations. You do your your renovations. It could affect costs later on.

Eric Ibey: Just gonna stop for a second and check the chat.

Eric Ibey: Okay.

Eric Ibey: alright, cool. Sorry, just taking a quick look at the chat. Alright.

Eric Ibey: So third one, you're gonna lower your greenhouse gases.

Eric Ibey: Kind of kind of obvious. But let's look at a chart that shows again for older merges. I'm I'm using the older merges archetype.

Eric Ibey: So our Ghg intensity.

Eric Ibey: So kilogram Co. 2 per meter squared. You can see from the baseline we're starting at around 42, 43 and getting down to about 10 at 0 carbon ready. Something interesting. I find interesting. The difference in emissions. Reduction from 0 carbon ready to Max site. Is not that significant?

Eric Ibey: at least not as significant as I originally thought it might be. So again, when we talk about the ground source heat pump versus air source heat pump.

Eric Ibey: Well, that doesn't look. That doesn't make the ground source seat pump as attractive as it should again.

Eric Ibey: very building specific, you might be able to make way. Better gains. But in terms of this is showing not a huge gain. So 0 carbon ready seems more attractive. It also seems more attractive, comes to the fourth point is that the 0 carbon ready scenario is cheaper. Ultimately, it's cheaper than going to this Max site, potential and more realistic.
Eric Ibey: So I'm going to give a little bit of love to the mid-size commercial building can see here at the bottom. Now we're talking. Capital costs dollars per square foot. So in a like for similar scenario.

Eric Ibey: you're looking at $63 per square foot. That's total to go up to 0. Carbon ready is $84 a square foot.

Eric Ibey: oh, $20 more, but 25 increase, I would say in most scenarios that I've seen the premium on going from like for similar to 0 carbon ready that 20 to 30% range seems pretty standard again depends on your building.

Eric Ibey: But to go from 0 carbon rating to the Max site it's a pretty big jump.

Eric Ibey: It's almost $30 a square foot.

Eric Ibey: So to get that very small gain in greenhouse gas emissions very small, gain in energy use, intensity.

Eric Ibey: Maybe that doesn't seem as worth it.

Eric Ibey: I think if I was a building owner I'd be dev definitely giving that a big, hard look. So that that's why it for the for this study we're saying that 0 carbon ready is you know, should be the goal.

Eric Ibey: So that's another question. What is the biggest challenge to decarbonizing your ability.

Eric Ibey: Suzanne? Thank you very much

Eric Ibey: alright. So we've got capital financing, lack of incentives, technical barriers, or lack of knowledge, lack of regulations or standards, human resource, capacity or other.

Eric Ibey: If you do have another. We'd love to hear what it is in the chat

Eric Ibey: way. Welcome to everybody that came in late. Thanks for being here. and thank you for participating in the polls. Alright, we got 71%, 5%. We're gone almost there.

Eric Ibey: Couple more seconds

Eric Ibey: more people griggle from 5, 4, 3, 2, one, all right.

Eric Ibey: and that share our results. So it looks like capital. Financing is the big winner. Surprise, surprise.

Eric Ibey: technical barriers, lack of knowledge, interesting lack of regulations. Also very interesting. Thank you very much. Everybody for participating. That's great.

Eric Ibey: And of course it's not a big surprise to see capital financing as the as the winner.

Eric Ibey: Alright! Can you confirm if that stop sharing? I have to click that a couple of times. Is it gone alright?

Eric Ibey: So next point

Eric Ibey: by going to net carbon, 0 carbon ready, you will improve your buildings. Resiliency resiliency is a word that is coming up a lot more lately given changing weather conditions.

Eric Ibey: Power outages. Resiliency is, I think, becoming a lot more pertinent on people's radars. And as it should.

Eric Ibey: how resilient is your building! How well can your building withstand a power outage or some sort of weather weather disaster? And when we talk about multi inter residential as we have been, mostly, as we saw in the beginning. Most of you are interested in those sorts of buildings, you know, where people live.

Eric Ibey: This this matters so the metric that we use to measure resiliency, or at least one of the metrics is called Teddy. Thermal energy demand intensity. So it's a energy per meter squared calculation, which is basically the heating load. It's only a heating time of year measurement, and it is a heating the heating load on your building.

Eric Ibey: So the things that decrease your thermal energy, demand intensity, are improving your envelope and improving the way you ventilate your building so as opposed to bringing 100% makeup, bear into your building. You know you replace that with heat, recovery, energy, recovery.

Eric Ibey: That also will get your Teddy down, and you can see through by this graph that the only 3 that get us down there, the fuel fuel switch ready, 0 carbon ready in the Max site.

Eric Ibey: The other ones don't get us too close. Now, why does this matter? And II found this graph. And I really really love this graph. So this is from the thermal Resiliency Design Guide at the University of Toronto. If you wanna dig farther into building resiliency.

Eric Ibey: Google, that maybe Suzanne can find that. Actually, I didn't put that in the notes, but that thermal. If you, if you're really interested, it's a great great guide so passive habitability as you can see. It's measure of how long a building remains habitable during extended power outages.

Eric Ibey: That's again like, I said, becoming more important. Given that. We've seen a lot of power outages in the last few years. So on this graph, you can see outdoor air temperature goes from above 2°C down to minus 10 over the course of a week.

Eric Ibey: That red dotted line is your survivability threshold. So 50°C is the is the line that below that your building is not survivable any longer and you can see a typical existing building drops below that threshold. After 2 days a code compliant building drops after 3 days, and a high performing building still stays habitable after 7 days and maybe longer.

Eric Ibey: That's becoming like, I say, a huge factor in why we should upgrade our buildings. This is not something that necessarily shows up in the Ghgs or your bottom line when you're you're talking about your electricity and gas bills.

Eric Ibey: But this is something that's becoming more and more important for residents of buildings all the time. So anyway, that's again again, if you want more information on resiliency, go check out that guide really really great resource.

Eric Ibey: Just gonna take a look at the challenge here. Thought, Thanks.

Eric Ibey: Jacob. Sorry I didn't. I missed that. In addition to the lack of human capital is also the the regulation like to like where it's nearly impossible to get approval by condominium members.

Eric Ibey: Yes, condos they are. They seem to be that that. That tough one. Right? That's yeah.

Eric Ibey: That's I'm gonna point to Marie. She is the expert on all things, Condo related. But again, we know that there's a lot of different challenges. And you know, again brings me back to my original point. It's a building by building basis. Everyone has different board members, and the way you share utility costs, it's. you know this, there's so much to this. So a. A. Again. I know this is very high level, but I hope it's also providing just a little bit of you know little bit of guidance or a little bit of hey? I didn't. I couldn't think about that. I didn't think about that before 6 point escalation rate.

Eric Ibey: So this was an assumption made in the modeling where you're seeing all these graphs and all this information coming from The electricity and gas escalation rates were assumed to be 2%. Now. this is like, I said, this is. This is not a knock on on what the assumptions are. This is how we have to run computer models is the way it goes. But

Eric Ibey: if we look at. So again, electricity and gas assumed to be both the same as an escal as an escalation rate. But the Canada Energy Regulator made an update in 2023, very recently. And you can see in commercial buildings electricity from 2023 to 24 to 2050

Eric Ibey: goes down. And this is projected year by year. You can go look at this. Again on the website. I think, Suzanne, did you share that? Oh, can I share it, please?

Eric Ibey: Absolutely so, if anybody wants to. You know, this is, this is a really cool tool but you'll see natural gas is going up from 2023 to 2050. It's more than tripling in cost now. Nobody has a crystal ball. Nobody knows exactly what the future holds.

Eric Ibey: but

Eric Ibey: if we're planning for the future asset management planning. And we're thinking about our buildings. If I were to go into the model, which, unfortunately, I can't, I don't have access to our consultants models. But if I were to go in and change those escalation rates to reflect what you're seeing on the screen right now and guarantee you those

Eric Ibey: all those scenarios that are dropping your emissions? Are gonna look a lot better. They're gonna look a lot more attractive because that cost of of gas is going up so much, and the cost of electricity is essentially dropping. So

Eric Ibey: again, we don't know what the future holds. But if we're talking about future proofing our buildings, planning for the future.

Eric Ibey: We don't know but you know the way things are going. If I had a crystal ball I would. Probably III think this is probably not far off. But again, who knows? We will see, time will tell.

Eric Ibey: And the final, the final thing that I wanted to mention in this model. Carbon price assumption was was used at $170 per ton as a flat rate into 2050.

Eric Ibey: Yeah, do we know what's gonna happen? Do we know what is going to happen with carbon pricing? No. That's a very political charge question.

Eric Ibey: But if the carbon price increased. if it increased over time, if it was higher than 170 per ton. Then, again.

Eric Ibey: those scenarios are going to change, and decarbonizing becomes a lot more attractive again.

Eric Ibey: So our final question, this is a pretty simple one. Does your building's long term asset management strategy incorporate carbon pricing.

Eric Ibey: basically yes or no, or not applicable to you. Give you a couple of seconds.

Eric Ibey: I used to know we're pretty neck and neck right now.

Eric Ibey: and go from 5, 4, 3, 2, one.

Eric Ibey: and share the results.

Eric Ibey: pretty even split from yes and no. Interesting.

Eric Ibey: yeah. Think that's that's good to know. So I would say that.

Eric Ibey: And just to expand on this real quick, if you are using, I mean, there are, there are free tools on the Internet that you can find red screen from Nrc. And is a pretty decent one. There's one called King set but you can. You can start to look, and some of you will probably been involved in other webinars and workshops have seen those. These are tools that you can use to predict what the you know what's gonna happen with utility costs, and you can adjust things like carbon pricing like escalation rates and get a better idea of, you know, what the future might hold, whether or not you do certain certain retrofits or not.

Eric Ibey: So

Eric Ibey: before I open it up, I just want to say that our next webinar is gonna be on October fourth 12 pm. Again. That's gonna be program purpose Update for the better buildings. Ottawa program. We hope that everybody here is a part of our better buildings auto-up program. So if you wanna scan I QR code,

Eric Ibey: you know. And you want to join that Webinar, please. We'd love to see you there.

Eric Ibey: We can throw. We can send out an email after with with all these things as well. If you don't quite get there. And on the left we, we have a newsletter if you'd like to subscribe a lot of great information there. And if you wanna send us an email, the emails at the bottom. You can also scan that QR code on the right to send us an email directly, like, I say, if you wanna take any of these conversations offline, if you think that it's a little bit in the weeds of your particular building, I'm happy to chat about it, and otherwise.

Eric Ibey: Thank you very much. All for being here, and I'm gonna open up the chat and see what we got here. Diana, please repeat the names of these tools to estimate carbon pricing. Sure red screen. II don't. I haven't played with redscreen a lot lately. I know there's been up some updates made, maybe Marie, or I don't know if you can comment on that specifically. But it's a pretty decent tool. King set

Eric Ibey: KKIN. GSET. T. Is another great asset management tool for predicting you know, paybacks and emissions, reductions. And and

Eric Ibey: you know also I would say that if you are part of the better buildings auto program and you are already reporting your data to Ewrb and sharing with auto, there's a lot of great stuff you can get out of that. So I would encourage you. If you are not reporting, please report. It is mandatory province wide, and if you are going to please share it with us, it helps us, and it helps.

Eric Ibey: you know, if the more we know, the more data we have, the more we can create incentives and programs that are gonna help buildings. Because, as we see, there is premium on going to net 0, that's we're not hiding that. That's that's just that's a reality.

Eric Ibey: But the more we know the more we can help. So you know, please get involved and and share that data with us. It would be really helpful.

Eric Ibey: And Diana, there's also another one. I'm I'm blanking on the name right now, but I can look that up later, and I'd be happy to send it over to you.

Eric Ibey: Will the presentation be shared? I absolutely we can. That's not a problem. We're gonna share some per, would you say? Are we not sharing it?

Suzanne Tewnion: I can speak to that. It will be shared. It probably usually takes about a month to, but you put up, but it will be on our better buildings Ottawa Web page.

Eric Ibey: I'm sorry you mean the the video or the actual slides.

Suzanne Tewnion: Oh, because I mean.

Eric Ibey: we can do both. And I mean the video takes a little longer. But I

Eric Ibey: we'll be quiet. Suzanne is the guard for that.

Eric Ibey: Will there be grants from the city to help buildings reach the Bbo targets, Samuel? That is a great question. I hope so. We're trying. We are working really hard on that.

Eric Ibey: There's that's that's a big part of what we do. And yeah, we're trying absolutely. But yeah, if we if we are expecting people to to do to go to net 0. There's gonna have to be some help. And it's it's not just coming from the city to. There's gonna be a lot of help coming from a lot of other places, too. So

Eric Ibey: we we are. I know we're working hard behind the scenes to to try to get those those rolled out for sure.

Eric Ibey: And again, if you are registered with better buildings, Ottawa you will get first first access. First look at information for all those things that come out.

Eric Ibey: we update that newsletter that I just shared. You know, that's something that you're gonna get that information right away, and you get in the door first to that money, because money is always incentives, grants. It's always limited. So you wanna be first again, if you are a part of our better buildings auto already, you're getting that knowledge. If you're not, I encourage you to sign up so you can get access to that.

Eric Ibey: Jacob, you're welcome. I'm glad it was helpful. Thanks for being here.

Eric Ibey: So what am I taking from today's webinar that since we have a plan or a study to replace signing with the next 5 years. This may be one of the best investment stores we're using kind of footprint. Or

Eric Ibey: do you agree with that?

Eric Ibey: Generally speaking, yes, I would say yes. And the thing is, Jacob, what's important is replacing siding. You have one chance to do building envelope work in the building's life.

Eric Ibey: New construction and one renovation is really what you're going to get. Probably. So if you're doing the siding.

Eric Ibey: Look, try to, you know. Maybe you're looking at the windows at the same time. If you've already got all that scaffolding and all that things set up. You wanna try to do as much as you can, because the chances are you're probably not gonna do it again. And especially if it's in 5 years, you know. You look at the sign. You look at the installation we also have. You know, we've been just as an aside. We've been. We've had some thermal scanning done at a lot of the buildings around Ottawa, and we've seen from those

Eric Ibey: thermal scans that most buildings have issues with with infiltration, with, you know, icing with thermal bridging. There's just so many issues going on with envelopes. So I would probably encourage you also to, you know, to have maybe a study done. Maybe you've already done that. But

Eric Ibey: you know, try to see what can be done.

Eric Ibey: At the same time as you're doing, deciding, because, like, I say, you, you get one shot at this. But yeah, I would. I would agree that that's one of the best things you can do right away.

Eric Ibey: and I, as I said, you improve your installation, you improve your envelope, it drops your heating and heating, cooling demand on your building the load. And now, when you go in 5, 1015 years to replace your central heating, your your whatever your you know, you put in an air source heat pump. Well, now, that heat pump can be a lot smaller, which means a lot cheaper. So you're gonna save money.

Eric Ibey: So thanks for the question.

Eric Ibey: no confirmation.

Eric Ibey: There are grants and fine thanks, Janice.

Eric Ibey: perfect. So there, there you have it, Samuel.

Eric Ibey: please loosed.

Eric Ibey: Go to our website. Check it out you're welcome and as appreciate you being here.

Eric Ibey: Yeah, thanks, Janice. Janice is the the authority on grants and and money. So II can't really answer that as well as she can. So thanks, Janice, and private funding. Absolutely.

Eric Ibey: Thank you. Thank you. Thank you. Oh, this is awesome. Brian. So there's no other questions.

Eric Ibey: Thank you all for being here much appreciated, taking time out of your lunch. Like, I say, if there's any questions, I'm really happy to get on email, jump on a phone call and and chat a little bit more about that. Otherwise have a great afternoon and a great rest of your day. Folks.
