du développement économique recommande au Conseil d’approuver :
1. La Politique sur les
immeubles écologiques en ce qui concerne les immeubles de la Ville d’Ottawa
ci-jointe;
2. Un investissement
additionnel de 5 % du coût total de construction de nouveaux projets afin de

The City of Ottawa has developed a Green Building Policy to enable new buildings and large scale renovations to be designed, delivered and operated in a more sustainable manner. The policy adopts LEED™ Canada, a not for profit rating system that promotes the development of buildings that are both ecologically and fiscally responsible.
The application of the LEED™ Canada Rating System to City of Ottawa buildings and renovations would demonstrate improved fiscal, social and environmental management. The rating system has four levels of LEED certification; certified, silver, gold and platinum. Each level has associated costs with varied annual savings and environmental benefits.
The Green
Building Policy was considered at the Corporate Services and Economic
Development Committee meeting of 19 April 2005 and at the Council meeting of 27
April 2005. The report had two
recommendations; to approve the Green Building Policy and to approve an
additional investment of 5% of the total construction cost of new
projects. Staff recommended the City
enroll at a "certified" level, as defined by LEED, based
predominately on the cost and benefits value.
The report dated 13 April 2005 is attached as Annex A.
As part of the approval process, Council asked that the item be referred back to staff for further information on the benefits and costs of the silver, gold and platinum levels of LEED programs and that the item be referred to the Environmental Advisory Committee (EAC) for their comment. The motion approved by Council follows.
"Moved by Councillor J. Legendre
Seconded by Councillor R. Jellett
That Item 8 of Corporate Services and Economic
Development Committee Report 26 be referred back to staff for further
information on the benefits and costs of the silver, gold and platinum levels
of LEED programs and that the Item be referred to Environmental Advisory
Committee for their comment."
DISCUSSION
This report addresses Council's motion by documenting the comments received from the EAC (attached as Annex B) and providing a summary of the cost/benefits analysis. The full analysis is attached as Annex C.
Comments from EAC
The
report was tabled at the EAC meeting of 12 May 2005 and select members from the
Committee reviewed the policy and provided comments for EAC's consideration at
their following meeting of 9 June 2005.
The comments led to the adoption of the following EAC
recommendation:
"Moved by P. Quealey
WHEREAS the Environmental Advisory Committee is
very supportive of the City adopting the LEED rating system for City of Ottawa
buildings; and
WHEREAS buildings that are LEED certified can
achieve life cycle cost savings and achieve a significant reduction in
operating costs (in the order of 25%); and
WHEREAS the City should seek to achieve the highest
possible LEED certified rating on the basis of life cycle costs; and
WHEREAS the City should consider investing a cost
premium greater than 5% when it can be demonstrated that the investment will be
paid back through a reduction in operating costs; and
WHEREAS the City should integrate in its Green
Building Policy alternate energy sources, such as geothermal heat exchange
system and hot water solar heating system; and
WHEREAS the use of alternate energy sources will
contribute to major reductions in energy use and greenhouse gas emission; and
WHEREAS Green Roof technology should be
incorporated in the Policy, especially for large corporate buildings to achieve
the greatest energy and environmental benefits; and
WHEREAS the City should consider the LEED rating
system when doing large scale renovation or re-capitalization projects of
existing infrastructure; and
WHEREAS the City should play a leadership role in
the community by serving as a model and sharing information with the private
sector; and
WHEREAS the City should consider partnership with
the private sector by participating in pilot projects like geothermal heat
exchange systems and should explore similar projects in residential
developments; and
WHEREAS the Policy's goal should be to achieve the
highest, most cost-effective environmental performance possible over the life
of a LEED certified building; and
WHEREAS staff should report back to Council on the
life cycle cost and environmental benefits of LEED certified corporate
buildings.
BE IT RESOLVED THAT the Environmental Advisory
Committee recommends that the City's Green Building Policy be amended to
include the above considerations; and
BE IT FURTHER RESOLVED THAT the Environmental
Advisory Committee recommends that the City of Ottawa pursue at least the
Silver LEED rating for corporate buildings on the basis of a balanced approach
considering benefits, including reduction in energy use and greenhouse gas
emissions, reduced operating costs, and incremental capital investment."
Upon
review of the above noted comments it has been determined that all of the
referenced items are taken into account within the LEED points rating
system. However, given the flexible
nature of the LEED rating system, each individual project can achieve its
desired rating using a different combination of selected measures. Therefore, not all measures will be
integrated into every project. The
measures that are most appropriate to each project's requirements and specific
location will be selected to achieve the desired rating on a project by project
basis.
The
analysis summary explains that LEED™ Ratings System points are awarded to
projects meeting defined performance benchmarks which surpass standard
construction practices. Improved
building performance is recognized by awarded ratings of: Certified, Silver,
Gold and Platinum, based on the total number of points achieved by a given
project. Points are awarded through an
independent review of project documentation by a panel of design professionals
that follow a predetermined and transparent process.
The
cost/benefit summary has determined that:
1.
there is no correlation between the point value of a LEED™
credit and the associated cost;
2.
there are a range of different strategies that can often be
used to earn the same individual LEED™ credit;
3.
the cost of some credits vary significantly based on the building
type and programming requirements; and,
4.
some credit costs can vary due to regional or programming
requirements.
The
LEED™ Rating System contains seven (7) prerequisites that all buildings must
incorporate and a ‘pick-list’ of potential credits, from which project teams
can choose, to achieve their desired level of certification. The ‘pick-list’ framework means that not all
projects achieving a defined level of certification will have incorporated the
same credits.
High
cost credits are typically only incorporated if a higher level of certification
is desired or if there are additional programming or location circumstances
that provide practical rationale.
At
the present time, there is an average cost premium of approximately 5%
associated with the design and delivery of a LEED™ - Certified building. These costs can be broken down over the
following areas:
· 1%
for project review and certification;
· 2%
for mechanical and electrical equipment upgrades; and
· 2%
for enhanced product specifications.
The
same studies have determined that there is an average cost premium of
approximately 9% to achieve LEED™ - Silver status. These costs can be allocated in the following areas:
· 1%
for project review and certification;
· 4%
for mechanical and electrical equipment upgrades; and
· 4%
for enhanced product specifications.
The
implementation of the LEED Rating System leads to sustainable development,
however, it requires a balance between environmental responsibility and fiscal
practically. As with any other
innovation there are associated costs.
Studies have examined the costs associated with these strategies, and it
has been generally determined that an initial investment in front costs yields
a savings of over ten times the initial investment.
It is anticipated that as the design and construction communities gain experience with the provision of sustainable buildings these costs will decrease. Based on the outcome of the cost/benefit summary, staff believe the City of Ottawa can, over time, obtain a Silver level or better of LEED certification as the industry develops and matures.
CONSULTATION
Staff have reviewed and considered the comments from the Environmental Advisory Committee.
FINANCIAL IMPLICATIONS
As
outlined in the original attached report
the adoption of “green” building practices as defined by LEED™ - Canada “Certified” will require an
additional up front capital investment of 5% of the cost of construction. This additional cost has not been reflected
in the City's Long Range Financial Plan documents.
In return for this additional investment, 25% annual energy savings will be delivered and savings equalling 10 times their investment cost over the life of the building.

REPORT RECOMMENDATION
That Corporate Services and Economic Development Committee recommend that City Council
RECOMMANDATION DU RAPPORT
Que le Comité des services organisationnels et du
développement économique recommande que le Conseil municipal
1. approuve la Politique en matière de construction durable pour les immeubles de la Ville d’Ottawa et
2. approuve l’investissement additionnel de 5 p. 100 du coût total de la construction pour tout nouveau projet et qu’il profite ainsi de la diminution des frais d'exploitation attribuable aux pratiques de construction durable, comme le décrit le présent rapport.
Given the world’s current needs and demands on our natural
environment it will not be possible to support current growth and development
trends on an ongoing basis. Within 30
years, the current rate of human consumption will reach depletion in several
key areas. Air, water and land are all
limited commodities and need to be managed responsibly in order to ensure their
availability for future generations.
All new buildings and large scale renovations have the potential to be designed, delivered, and operated in a more sustainable manner. LEEDTM - Canada is a not for profit rating system that promotes the development of buildings that are both ecologically and fiscally responsible. The program uses a scientific based framework to determine building performance and sustainable design achievements through the use of common standards of measurement that are easy to apply. The LEEDTM - Canada Rating System can clearly demonstrate improved fiscal, social and environmental management.
Through the adoption of the Green Building Policy the delivery of building projects as defined by LEEDTM - Canada “Certification” the following benefits can be achieved:
- 25% annual utility cost savings over current practices
- reduced life cycle costs through enhanced material selection
- reduced material consumption during manufacturing and transportation of selected building products
- reduced waste generation during construction
- reduced water consumption resulting from the use of more efficient systems and devices
- improved indoor environment
- healthy and productive work environments
- demonstrated leadership in environmental stewardship
- reduced greenhouse gas GHG emissions
- reduced utility consumption and cost
- reduced water consumption and cost
- reduced waste generation
- improved indoor air quality
Étant donné les besoins
et les pressions qui, à l'échelle mondiale, pèsent actuellement sur notre
environnement naturel, il ne sera pas possible de maintenir à long terme les
tendances actuelles de croissance et de développement. Le rythme actuel de la
consommation humaine entraînera, d'ici 30 ans, un épuisement de plusieurs
ressources clés. L'air, l'eau et la terre sont tous des ressources limitées qui
doivent être gérées de manière responsable afin d'en assurer la pérennité pour
les générations futures.
La conception, la construction et
l'exploitation des nouveaux immeubles et des rénovations immobilières
d'envergure peuvent se faire d'une manière plus écologique. LEEDMC-Canada est un système de
cotation sans but lucratif qui promeut la construction d'immeubles qui sont à
la fois écologiques et économiques. Ce programme applique un schéma
scientifique pour déterminer le rendement des immeubles et les objectifs
conceptuels écologiques au moyen de normes de mesure communes et faciles
d'application. Le système de cotation de LEEDMC-Canada peut faire ressortir clairement les
améliorations de la gestion budgétaire, sociale et environnementale.
Par suite de l'adoption d'une
politique de construction écologique, la réalisation de projets immobiliers
ayant obtenu la « certification » LEEDMC-Canada pourra produire les avantages
suivants :
-
économie
de 25 % du coût annuel de l'énergie par rapport aux pratiques actuelles;
-
réduction
des coûts du cycle de vie par un meilleur choix des matériaux;
-

Given the world’s current needs and demands on our natural
environment it will not be possible to support current growth and development
trends on an ongoing basis. Within 30
years, the current rate of human consumption will reach depletion in several
key areas. Air, water and land are all
limited commodities and need to be managed responsibly in order to ensure their
availability for future generations.
The environmental impact resulting from the use of buildings in North America is well documented. Studies carried out by the U.S. Green Building Council as well as the Department of Natural Resources Canada have shown that they use:
- 65% of total electricity generated
- 36% of total energy consumed
- 12% of potable water
- 40% of global material flow
In addition, building supply and construction activities also generate:
- 33% of the waste stream through construction, renovation and demolition activities
- 30% of greenhouse gas emissions (one of the principle causes of smog)
These numbers are estimated to be comparable to Ottawa’s consumption rates.
In order to reduce the environmental impacts of buildings, the City of Ottawa’s current building practices can be enhanced and aligned with leading trends in environmental and energy management.
The Ottawa 20/20 plan identifies liveable communities that are environmentally sensitive and healthy as one of its principle goals. As a key player in community development, the City of Ottawa has the opportunity to show environmental stewardship and leadership as well as prudent financial management by ensuring that its building facilities are managed in a responsible and sustainable manner.
All new buildings and large scale renovations have the potential to be designed, delivered, and operated in accordance with the Canada Green Building Council’s Leadership in Energy and Environmental Design Rating System (LEEDTM - Canada).
LEEDTM - Canada is a not for profit rating system that promotes the development of buildings that are both ecologically and fiscally responsible. The program uses a scientific based framework to determine building performance and sustainable design achievements through the use of common standards of measurement that are easy to apply. The LEEDTM - Canada Rating System can clearly demonstrate improved fiscal, social and environmental management.
DISCUSSION
There are significant benefits associated with the responsible management of natural resources and the environment. Green building practices not only reduce the impact of building activities on limited renewable and non-renewable resources, they also reduce the cost of owning and operating those facilities over their complete life cycle.
However, these initiatives must be measurable and verifiable in order to prove their true value. The adoption of a structured rating system against which to measure, verify and report upon the sustainability of building initiatives, undertaken by the City of Ottawa, will demonstrate commitment and leadership at the local, national and international level.
Standards to measure and rate the environmental impact and sustainability of building activities have been created by a number of national and international agencies. Following a review of available rating systems, it has been identified that the Leadership in Energy and Environmental Design (LEEDTM - Canada Rating System) strongly supports the goals and objectives identified in the Ottawa 20/20 Growth Management Plan. The LEEDTM - Canada Rating System was created and released by the Canada Green Building Council in September 2004, taking Canada’s geography and climate conditions into account.
The LEEDTM - Canada Rating System looks at building practices under the following categories and awards points based on their proven performance: (see Appendix B for detailed explanation)
- site development
- water efficiency
- energy and atmosphere
- materials and resources
- indoor environmental quality
- innovation and design process
A total of 70 points are available within the LEEDTM - Canada Rating System and completed projects are ranked according to the project delivery practices employed on a project-by-project basis. The available rating categories are as follows:
- LEEDTM - Canada “Certified” – 26 to 32 points,
- LEEDTM - Canada “Silver” – 33 to 38 points,
- LEEDTM - Canada “Gold” – 39 to 51 points, and
- LEEDTM - Canada “Platinum” – 52 to 70 points.
It is proposed that all new building or renovation projects be delivered as LEEDTM - Canada “Certified” projects which require between 26 and 32 points to receive accreditation.
At the present time several Canadian cities have or are in the process of adopting the LEED - Canada rating system. These include:
- Calgary (LEED Silver)
- Kingston (LEED Silver)
- Victoria (LEED Silver)
- Vancouver (LEED Silver)
- Public Works and Government Services Canada PWGSC (LEED Silver)
In addition, many U.S. state departments, state governments and municipalities have also adopted the LEED rating system.
Through the delivery of “Green Buildings” as defined by LEEDTM - Canada “Certification” the following benefits can be achieved:
- 25% annual utility cost savings over current practices
- reduced life cycle costs through enhanced material selection
- reduced material consumption during manufacturing and transportation of selected building products
- reduced waste generation during construction
- reduced water consumption resulting from the use of more efficient systems and devices
- improved indoor environment
- healthy and productive work environments
- demonstrated leadership in environmental stewardship
Sustainable building practices not only demonstrate responsible leadership practices, they also demonstrate good business practices. Through the investment of an additional 5% of the total cost of construction new City buildings can be LEEDTM - Canada “Certified”, achieve life cycle cost savings and achieve a 25% reduction in operating costs. This increased investment of 5% is broken as follows:
Project
Certification
Project
review and certification 1% additional cost.
This work is undertaken by the Canada Green Building Council on a not
for profit basis.
A comprehensive report prepared by California’s Sustainable Buildings Task Force entitled “The Costs and Benefits of Green Buildings” determined that an additional “minimal upfront investment of about 2% of construction costs typically yields savings of over ten times the initial investment.
Adherence to the energy performance standards required for LEEDTM - Canada “Certification” produces buildings that are 25% more energy efficient than buildings being delivered based on the current Model National Energy Code. This means that a 2% increase to purchase more efficient heating and air conditioning equipment yields 25% energy savings each year.
Example: a project with a total construction cost of $7.5 million and an annual utility budget of $80,000 will require an additional investment of $150,000 to gain a utilities savings of $20,000 annually. This results in a 7.5 year simple payback period on the investment and ongoing benefits thereafter.
This brings the total additional upfront investment required to deliver LEEDTM - Canada “Certified” building projects” to 5% of the total cost of construction.
The draft “Green Building” policy was circulated to the Planning, Environment and Infrastructure Policy Branch of the Planning and Growth Management Department. The comments returned indicated that the proposed policy supports the goals and directions layout in the City’s 20/20 Plan and supporting plans. The proposed Green Building Policy is particularly supportive of the goals and directions identified in the Corporation’s Environmental Strategy.
The draft “Green Building” policy was circulated to all Divisions within Corporate Services Department, Real Property Asset Management Branch (RPAM) to align building design, construction and operating practices. The comments returned indicated that the proposed policy supported best practices in the various disciplines.
The adoption of sustainable building practices as defined by LEEDTM - Canada Rating System “Certified” will result in significant environmental benefits and cost savings. A LEEDTM - Canada “Certified” project will deliver the following improvements in building practices:
- reduced greenhouse gas GHG emissions
- reduced utility consumption and cost
- reduced water consumption and cost
- reduced waste generation
- improved indoor air quality
The adoption of “green” building practices as defined by LEEDTM - Canada “Certified” will require an additional up front capital investment of 5% of the cost of construction.
In return for this additional investment, 25% annual energy savings will be delivered and savings equalling 10 times their investment cost over the life of the building.

Énoncé |
The City of Ottawa is committed to a sustainable existence and strives to reduce the environmental impacts of its operations. In recognition of the potential negative impacts associated with the design, construction and operation of the civic building inventory all new buildings will be designed and delivered in accordance with the ‘Certified’ performance level of the Leadership in Energy and Environmental Design – Canada (LEEDTM - Canada) Building Rating System. The design, construction and operation of the municipal building inventory not only requires significant capital expenditures but has documented negative environmental impacts. The design and delivery of municipal buildings that have been LEEDTM – Canada “Certified” clearly demonstrates improved fiscal, environmental, and corporate responsibility. |

La Ville d'Ottawa adhère rigoureusement aux
principes de durabilité de son urbanisation et s’efforce de réduire les
répercussions de ses activités sur l’environnement. Compte tenu des effets
négatifs potentiels associés à la conception, à la construction et à
l'exploitation des immeubles municipaux, tous les nouveaux bâtiments seront
conçus et aménagés conformément au niveau « certifié » du système
d’évaluation des bâtiments LEEDTM
(Leadership in Energy and Environmental Design – Canada – leadership en
matière d’énergie et d’environnement – Canada). La conception, la construction et l'exploitation
des immeubles municipaux demandent d’importantes dépenses en immobilisations
et peuvent se répercuter négativement sur l'environnement. La conception et
l’aménagement d’immeubles municipaux qui obtiennent la certification de LEEDTM – Canada sont la preuve
évidente d’un plus grand sens des responsabilités sur les plans financier,
environnemental et municipal. |

The Leadership in Energy and Environmental Design Green Building Rating System (LEEDTM)
LEEDTM is a voluntary consensus based standard for the development of high performance sustainable buildings that reduce the documented environmental impacts associated with the construction industry. The program was originally developed by the U.S. Green Building Council (USGBC) and has been adapted for Canadian markets by the Canada Green Building Council (CaGBC). The LEEDTM toolkit currently includes a standard for new construction projects, LEEDTM-NC and other tools are to be available shortly. Both LEEDTM-EB (Existing Buildings) and LEEDTM-CI (Commercial Interiors) have completed the pilot project phase and are in the final comment process. These tools are expected to be released for application and project registration very shortly.
LEEDTM promotes the development of buildings that are both ecologically and fiscally responsible. The program uses a scientific based framework to determine building performance and sustainable design achievements through the use of common standards of measurement that are transferable and easy to use.
The system addresses building performance within six categories. Each category contains a series of mandatory prerequisites and achievable credits, which are defined by benchmarks. Documentation of design and construction accomplishments that meet or exceed the stipulated benchmarks allows for accumulation of points. The number of points achieved determines the LEEDTM designation awarded. The requirements out of a total of 70 points are:
This is the first category in which points can be achieved. There is one prerequisite and 14 possible points available. All projects must develop Erosion and Sedimentation Plan to reduce negative impacts on water and air quality. Other points are available for:
This category is designed to reduce the water use within a building thereby reducing the load on municipal services for water treatment and sewage requirements.. There are no prerequisite requirements and there are five possible points within three credits. Points can be achieved for:
There are three prerequisites and six credits that provide a possible 17 points. The intention of the LEEDTM Energy and Atmosphere category is to reduce the depletion of non-renewable energy resources, reduce related environmental impacts, such as emissions, and to encourage the use of renewable energy sources. The City of Ottawa will explore incorporating energy efficiency as mandatory requirements to ensure maximum return on operating savings.
At minimum, projects are required to establish and achieve a minimum level of performance by compliance with ASHRAE 90.1 or by using the Model National Energy Code for Buildings. Systems must also receive basic commissioning to ensure that fundamental elements have been designed, installed and properly calibrated to operate as intended. Projects are not to use CFC based refrigerants in their HVAC or refrigeration equipment, to reduce ozone depletion. Points can be earned for:
There is one prerequisite and fourteen possible points in this category. The intention of these credits is to encourage design strategies that reduce and reuse material resources and construction waste, and to encourage the selection of building materials that have reduced emissions, contain recycled content, are manufactured from renewable resources or provide other reduced impacts to the environment. The one requirement in this category is that the building be designed to facilitate the reduction of waste generated at the site by providing an easily accessible area that is dedicated to the separation, collection and storage of materials including; paper, corrugated cardboard, glass, plastics and metals. Other credits address:
There are two prerequisites and eight credits that allow for a possible 15 points in this category. The first prerequisite requires that the project meet the requirements of the standard ASHRAE 62 – Ventilation for Acceptable Indoor Air Quality, in order to provide indoor air quality (IAQ) performance for the health, comfort and well being of the building occupants.
The second requirement addresses the control of environmental tobacco smoke within the building. The program requires that building occupants be protected from exposure to tobacco smoke by prohibiting smoking within the building and the designation of exterior smoking areas away from entries and operable windows. As the City already has a no smoking policy for public buildings this credit is already mandated.
Other credits within this category include:
This is the final category and there are five possible points available. The first four points are provided for exceptional performance above the requirements of the LEEDTM Green Building Rating System and/or performance in green design categories that are not currently addressed. The final credit is available for having the project guided by a LEEDTM Accredited Professional. Persons that have achieved this accreditation have received training in the principles of sustainable design and have successfully completed the LEEDTM Accredited Professional exam.
Many of the aspects of the LEEDTM Green Building Rating System reflect environmental commitments that have been made in the Ottawa 20/20 Environmental Strategy. The rating system provides a framework for measuring delivery towards these promises. In many municipalities across the United States the LEEDTM Rating System has been adopted by both public and private organizations as an example of corporate leadership and environmental responsibility. Designing and constructing building to LEEDTM certification has become ‘matter of course’ and is just the way of doing businesses. The City of Ottawa would hope that other organizations will follow their lead and develop similar policies for future construction or major renovation projects. The table on the following pages provides a more in-depth overview of the LEEDTM framework.
Annex B- EAC Comments and Extracts fo
Minutes from HRSSC 9 June 2005
Green Building Policy
Introduction
The City of Ottawa has developed a green building policy that will ensure the delivery of building projects as defined by LEED (Leadership in Energy and Environmental Design) rating system. As part of the approval process Council asked that the item be referred back to staff for further information on the benefits and costs of the silver, gold and platinum level of LEED programs and that the Item be referred to the Environmental Advisory Committee (EAC) for their comment.
Comments
The EAC is very supportive of the City adopting the LEED rating system in the design of building projects. The intention is to achieve initially LEED Canada Certified but the City should pursue higher ratings when it is justified on the basis of life cycle cost savings. The City should not limit the additional investment at 5% of the total construction cost of new project when it can be demonstrated that the investment will be paid back through a reduction in operating costs. Instead, capital budgets which are impacted by this Policy will be expected to be budgeted to meet a minimum of LEED Silver Rating. Budget planning involving life cycle cost analysis to achieve a higher rating of gold or platinum is encouraged. The Policy’s goal should be to achieve the highest, most cost-effective environmental performance possible over the life of the facility.
The Policy should have a provision to report back to Council on the life cycle cost and environmental benefits of LEED certified corporate buildings.
As part of the design of building projects, the City should also integrate in its Green Building Policy alternate energy sources, such as geothermal heat exchange systems and hot water solar heating system. Alternate energy sources such as these can contribute to major reductions in energy use and greenhouse gas emissions.
In an effort to achieve the greatest energy and environmental benefits, the City should also consider Green Roof technology in the building design, especially for large corporate buildings which is the main focus of the Policy. Already, Green Roof projects have been demonstrated at Toronto’s City Hall and Vancouver Public Library.
The City should also consider the LEED rating system when doing large scale renovation or recapitalization projects of existing infrastructure to achieve the highest most cost-effective environmental performance possible over the life of the facility.
The City should also play a leadership role in the community by serving as a model to the private sector. It should share information on its experience and encourage the private sector to design building in accordance with the LEED rating system. The City should also look at partnership with the private sector by participating in pilot projects. Geothermal heat exchange projects in residential developments offer promise in this regard.
Conclusion
The EAC recommends that the City Green Building Policy for the construction of corporate buildings be amended to include the above considerations.

Annex C- Cost/ Benefit Analysis
LEED RATING SYSTEM – Cost / benefit summary
An increased awareness of environmental
issues as a whole and specifically the environmental and health impacts of our
constructed environments have lead to a widespread demand for a common
framework for the assessment and certification method for green buildings. In response to this demand, the Leadership
in Energy and Environmental Design (LEED™) Green Building Rating system was
developed by stakeholders in the building industry.
As result of the proven benefits of green
buildings, many organizations are adopting ‘Sustainable Building Policies” that
require all new construction or major renovation projects to be designed and
delivered using the LEED™ Rating System.
The City of Ottawa is considering adopting a policy that would call for
all future municipal buildings over 500 m2 in area to be LEED™ Certified initially and LEED™ Silver once
experience has developed in the methodology.
The process does require adaptations to standard design and,
construction practices and as with any change, there are always concerns
regarding the cost implications.
However, it is important to note that the definition of sustainable
development calls for a balance between environmental responsibility and fiscal
viability.
In order to fully understand the cost implications associated with the
LEED™-Canada framework, the City of
Ottawa commissioned Jacques Whitford Limited to review reports that have been released to determine if costs can be allocated
to specific credits within the LEEDTM
framework. Within the LEED™ Ratings System, points are awarded to projects that
meet defined performance benchmarks which surpass standard construction
practices. Improved building
performance is recognized by awarded ratings of; Certified, Silver, Gold and
Platinum, based on the total number of points achieved by a given project. Points are awarded through an independent
review of project documentation, by a panel of design professionals that follow
a predetermined and transparent process.
It is important to remember that sustainable
development requires a balance between environmental responsibility and fiscal
practically. It has been determined
that:
·
there
is no correlation between the point value of a LEED™ credit and the associated
cost;
·
there
are a range of different strategies
that can often be used to earn the same individual LEED™ credit;
·
the
cost of some credits varies significantly based on the building type and
programming requirements; and,
·
some
credit costs can vary due to regional or programming requirements.
The LEED™ Rating System contains seven (7)
prerequisites that all building must incorporate and a ‘pick-list’ of potential
credits from which project teams can choose to achieve their desired level of
certification. The ‘pick-list’
framework means that not all projects achieving a defined level of
certification will have incorporated the same credits.
Projects will naturally ‘cherry pick’ credits
in the initial planning phase by determining credits that are either inherent
to the design or can be incorporated with minimal additional premium cost
implications. The project team will
then examine the possibility of incorporating credits that may have a higher
cost premium. High cost credits are
typically only incorporated if a higher level of certification is desired or if
there are additional programming or location circumstances that provide practical
rationale.

Studies have proven that over their
lifecycles green buildings use less energy and water, generate less greenhouse
gases and other pollutants, use natural resources wisely, and generate less
waste. Building operation costs are
reduced and typically economic lives are increased. Indoor environments are healthier as a result of improved
ventilation, thermal comfort, natural light and reduced source emissions. Providing healthier indoor environments
reduces ‘sick-building syndrome’ and the risks of potential litigation. In addition, research has found that
improved indoor environments result in increased productivity, decreased
absenteeism and improved worker morale.
Sustainable buildings are considered a key component in the quest to
achieve sustainable development to support our quality of living.
Studies have found that ‘green’ buildings
provide:
·
a
annual utility savings, often in the are of about 25%;
·
provide
reduced maintenance costs, through improved material selection;
·
generate
less waste, both during construction and operation;
·
provide
healthier indoor environments and improved worker satisfaction through the
provision of better quality indoor environments; and,
·
demonstrate
environmental leadership.
As with any other innovation there are associated costs. Studies[1] have examined the
costs associated with these strategies, and it has been generally determined
that an initial investment in front costs yields a savings of over ten times
the initial investment.
At the present time, there is an average cost premium of approximately
5% associated with the design and delivery of a LEED™-Certified building. These costs can be broken down over the
following areas:
The same studies have determined that there is an average cost premium
of approximately 9% to achieve LEED™-Silver status. These costs can be allocated in the following areas:
However, it should be noted that as the design and construction
communities gain experience with the provision of sustainable buildings these
costs are expected to decrease. It is expected that in the near future the cost
premium for LEED™-Silver status will decrease to the 5% range and LEED™-Gold
will be attainable for the 9% premium.

Councillor Legendre expressed his thanks and congratulations to staff on this matter, noting when the report was first before Council in April of this year he had moved the motion to refer it back. The Councillor opined the recommendations contained in the present report were considerably improved and felt the City would be well served by this more aggressive approach.
That
the Corporate Services and Economic Development Committee recommend that City
Council approve:
1. The attached “Green Building Policy for the City of Ottawa
Buildings”;
2. The additional investment of 5% of the total construction cost of new
projects in order to take advantage of the operating cost savings associated
with sustainable building practises and achieving the LEED Certification target
as a minimum, as outlined in the report; and
3. That staff pursue the Silver LEED rating when it can be
demonstrated that the investment will be paid back through a reduction in
operating costs over a period of seven years, and that staff report back to
Committee if there is a need for additional capital funding to achieve those
savings.
