1 Sustainable Building Policy Oliver Bowen Maintenance Facility 2011 Annual Report Building a great city The City achieved three LEED certifications in Executive Summary This report, the fifth annual on The City of Calgary s Sustainable Building Policy (SBP), provides an overview of the achievements in the 2011 calendar year and outlines ongoing sustainable building initiatives moving forward. Infrastructure & Information Services (IIS) is responsible for the development, implementation, evaluation and annual reporting of the SBP. The Sustainable Building Policy provides direction across all City business units and to civic and community partners. The SBP continues to position Calgary as a national leader and has been a catalyst for change towards more sustainable building construction and operating practices. As the benefits of sustainable buildings become more recognized, the number of certified projects has steadily increased since the SBP came into effect in The City added three additional Leadership in Energy and Environmental Design (LEED ) certified projects in 2011, for a total of 12 LEED certified City-owned and City-funded buildings in Calgary s building inventory. The 2011 additions are: Valley Ridge Fire Station No. 35 (LEED Canada New Construction (NC) v1.0 Gold). Oliver Bowen Maintenance Facility (LEED Canada NC v1.0 Gold). TRICO Centre for Family Wellness arena expansion (LEED Canada NC v1.0 Certified). New and upgraded buildings require monitoring and measurement to verify the performance impacts of integrated design and green building systems. It is through these measurements and analysis that buildings can evolve to be more durable and healthy, and to operate more efficiently on lower budgets. The Sustainable Buildings Partnership Program (SBPP) continues to focus on upgrades to existing City-owned facilities to improve energy and water efficiency and to measure the performance of existing buildings. The SBPP has allocated $4.2 million of Municipal Sustainability Initiative (MSI) funding to City business units over 2010 and Projects include energy audits, lighting upgrades, sub-meter installations, a solar thermal pilot project, irrigation controls to reduce water use, a green roof initiative and a material reuse demonstration. In 2011, IIS and the Office of Land Servicing and Housing began a review of the rating system target of BuiltGreen TM Silver which applies to City-funded affordable housing projects. This review begins the process of updating the SBP, ensuring the policy remains current and relevant. The SBP is an evolving document that must respond to the needs of individual business units, industry trends and technical innovations, and align with the strategic vision and direction set by Council priorities and policies. The City continues to build on lessons learned to demonstrate that strategic planning, innovative ideas and fiscal responsibility will result in an inventory of sustainable buildings that pass on economic, social and environmental benefits to generations of Calgarians to come. calgary.ca call Onward/ The City will lead in developing and managing adaptable facilities to improve economic, environmental and social benefits

2 Southland Leisure Centre New City-owned or City-funded occupied facilities in excess of 500 m 2 are required to meet LEED NC Gold certification. Introduction Infrastructure & Information Services (IIS) is responsible for annually reporting to the Standing Policy Committee on Utilities and Corporate Services regarding how well City facilities meet the goal of sustainability. In alignment with The City s commitment to sustainability and fiscal responsibility, the 2011 Sustainable Building Policy Annual Report and supporting information is again being made available in digital format on The City s website: calgary.ca/cs/iis/pages/about-landinformation/sustainable-building-policy.aspx. The purpose of the Sustainable Building Policy is to ensure all City-owned and City-funded facility planning, designing, constructing, managing, renovating, operating and demolishing is carried out in a sustainable manner that considers the triple bottom line while enhancing The City s reputation for fiscal responsibility, and supporting the health and well-being of facility users. As the SBP becomes more widely adopted, it is expected lifecycle costs are being reduced, and healthier, more durable and adaptable buildings are being constructed. Twelve City business units own or operate buildings and are impacted by the SBP. IIS continues to partner with these business units to achieve SBP compliance through technical and project management support, option analysis, education, training and awareness, and limited capital project funding. Leadership in Energy and Environmental Design is a rating system which evaluates environmental performance from a whole-building perspective. Within Canada there are six LEED rating systems. To date, The City has achieved certification in two of the six rating systems: New Construction & Major Renovations (NC), and Commercial Interiors (CI). LEED Canada NC 2009 includes the following seven sustainable building categories: Sustainable Sites Water Efficiency Energy and Atmosphere Materials and Resources Indoor Environmental Quality Innovation and Design Process Regional Priority Within each category are minimum performance requirements, referred to as prerequisites, together with optional credit performance requirements. Achievement of all prerequisites, together with sufficient credits, serves to verify sustainable building practices. As technology and knowledge surrounding sustainable buildings increases, green building rating systems such as LEED are evolving to support and promote higher standards of building construction, with a focus on strategic, long-term benefits. As such, minimum performance requirements for credit achievement have increased over time. For example, in the recent revision of the new construction green building rating system, water use reduction performance requirements increased from an optional credit to a prerequisite of 20 per cent reduction relative to a calculated baseline. Through its evolving green building rating system, the Canada Green Building Council (CaGBC) continues to encourage additional energy use reductions in sustainable building projects by significantly increasing credit achievement opportunities for optimizing energy performance. The City of Calgary is keeping pace with these increasing performance standards. Page 2

3 Valley Ridge Fire Station No. 35 Green building rating system target achievements The City of Calgary is a leader within the community, and continues to integrate social, economic and environmental responsibilities when developing new sustainable buildings. The original Sustainable Building Policy in 2004 required City-owned or City-funded building to target LEED Silver. In 2008, Council amended the SBP to require new occupied facilities in excess of 500 m 2 to meet or exceed the green building rating system target of LEED Gold. Figure 1 outlines the sustainable building rating systems and targets for City-owned and City-funded buildings, as set out in the SBP.

5 Green building rating system target achievements continued Figure 3 illustrates that the total number of LEED certified buildings owned and funded by The City has increased from three in 2005, to 12 in By the end of 2011, there were 33 LEED certified buildings in Calgary representing various building uses. The increased number of LEED certified buildings in Calgary s public and private sectors demonstrates the community s shift in values, and recognition of the long-term benefits of sustainable buildings. The City continues to lead by example on strategic and sustainable issues in the community, and to demonstrate to the private and public sectors that sustainable development is an achievable, fiscally responsible, strategic goal that benefits future generations. Figure 3: 2011 cumulative LEED certified buildings City-funded City-owned YEAR Other certified projects in Calgary NUMBER OF LEED CERTIFIED BUILDINGS Note: Includes buildings certified under LEED New Construction & Major Renovations (NC), Commercial Interiors (CI) and Core and Shell (CS). Canada Green Building Council (CaGBC) data demonstrates that The City of Calgary s average LEED credit achievement and the Canadian average credit achievement are very similar. 1 The City of Calgary consistently achieves LEED credits by diverting over 75 per cent of project construction waste from City landfills. All 12 certified projects reduced water use by at least 30 per cent (as compared to a traditional building), as well as achieving the green power credit as a result of The City s Energy Services Agreement (Retail). As shown in Figure 4, there are 194 projects in Calgary which have been registered with the CaGBC. The City currently has a total of 32 City-owned or City-funded projects registered with the Canada Green Building Council. Seventeen of the 32 projects are targeting LEED Gold certification, 10 targeting LEED Silver certification and five targeting LEED Certified. Ten of the registered projects are nearing completion and the final stages of certification.

6 The Water Centre Triple bottom line performance monitoring The City commissioned 10 facility energy audits in The City has strategically adopted a triple bottom line strategy which involves measuring and reporting on factors such as greenhouse gas emissions, community engagement, and environmental health and safety. In order to report on these initiatives, measurements must be obtained to identify baselines and quantify successes. It is important to measure the performance of buildings once they are occupied to evaluate water conservation and reduced energy use. Operational efficiency in these areas correlate to reduced operating costs over the life of the building. To date, it has been difficult to measure the success of the Sustainable Building Policy without quantifiable performance data, such as electrical, natural gas or water usage, consistently correlated with unique building variables such as floor area, building uses, schedule and occupancy. The Sustainable Buildings Partnership Program (SBPP) was developed to enable City business units to better measure performance, upgrade building systems, and evaluate sustainable building technologies for existing City facilities. The SBPP stewards funding from the Municipal Sustainability Initiative (MSI) and Pay-As-You-Go capital, with total funding of approximately $20 million in 2010 through In 2010, this program committed $1.6 million to upgrading the operational performance of existing City-owned buildings, with an additional $2.6 million allocated for SBPP projects in The SBPP promotes a collaborative, cross-departmental approach to problem solving and project delivery. IIS has partnered with Recreation, Parks, Fire, Roads, Corporate Properties & Buildings, Water Resources, Water Services, Transit and Animal & Bylaw Services to undertake unique projects with measureable results. Projects initiated to date are of four main types: energy audits, sub-metering, building and site upgrades, and technology pilots. Page 6

7 TRICO Centre for Family Wellness Sustainable Buildings Partnership Program achievements Roofing material salvaged from the Talisman Centre was used to create new storage facilities. In 2011, The City commissioned 10 energy audits at its recreational facilities, water and wastewater treatment facilities and at a fire station. The energy audits will be used to prioritize sustainable initiatives at the facilities in the future. Planning was completed for the installation of 24 electricity sub-meters at four recreation facilities and one water treatment facility, along with process water meters at Max Bell arena. In 2012, building owners will be able to use the sub-meter data to quantify energy and water use, and to identify opportunities for improved performance. The SBPP has funded several lighting and lighting control upgrade projects. In 2011, Recreation and IIS partnered to plan lighting upgrades at 10 City arena bowls. These projects have an anticipated average simple payback of 10 years. A partnership between IIS and Corporate Properties & Buildings delivered lighting upgrades that improved lighting levels and energy efficiency at the Manchester Building Q. The holistic approach taken in the project planning and delivery ensured that the old materials were properly disposed of. Twelve kilograms of the total 12.5 kg fixture weight was successfully recycled for all 129 light fixtures. In 2011 the Talisman Centre Roofing Reuse Project saw construction of 10 maintenance equipment storage facilities at various Parks and Recreation sites across the city, with eight facilities to be constructed in 2012 for a total of 100 bays. The storage facilities constructed using the roofing material salvaged from the Talisman Centre roof replacement project will protect and prolong the life of City maintenance equipment. The reuse of the roofing material also diverted approximately 3,000 m 2 of waste material from City landfills. Inclusion of performance monitoring as a part of each SBPP project plan ensures triple bottom line performance improvements are being measured. Performance monitoring is under way at several projects including the Southland Leisure Centre solar thermal project, and results will be communicated in future reports. IIS Engineering & Energy Services division is also using MSI funding to purchase an energy information software system called Energy Cap. The software will track, monitor, analyze and report energy consumption, costs and trends. In addition, it will enable Environmental & Safety Management to report on corporate emissions and greenhouse gases. Another MSI-funded corporate initiative, the IIS Building Repository Project, will support more accurate and consistent data collection, and better enable comparative building performance measurements in the future.

8 Cardel Place The City continues to successfully achieve the green building rating system targets set by the Sustainable Building Policy. Policy review and update In 2008, The City revised its Sustainable Building Policy to include a sustainable building rating system target for affordable housing projects funded by The City. At that time, a target of BuiltGreen Silver was adopted for new affordable housing projects, with the expectation that the rating system and target level would be piloted for a minimum of two years. In 2011, Infrastructure & Information Services and the Office of Land Servicing & Housing began a review of this pilot. These business units are working together to gather lessons learned from the pilot, research third-party rating systems suitable for affordable housing projects and explore approaches undertaken by other North American municipalities and affordable housing agencies. Ensuring alignment with existing City of Calgary, Calgary Housing Company, and other affordable housing funding agency requirements, the review team will deliver recommendation(s) for updating the Sustainable Building Policy, keeping the Policy current and consistent with The City s sustainability objectives. The pilot review project will serve as an example of how the SBP as a whole can be reviewed and updated over the coming years. Future directions Year after year, The City continues to successfully achieve the green building rating system targets set by the Sustainable Building Policy. With 32 projects currently registered with the Canada Green Building Council, a significant number of additional LEED certifications are anticipated in the coming years. Infrastructure & Information Services continues to pursue opportunities to raise awareness of the intent and strategic benefits of the SBP. Through increased awareness, business units can make better-informed, strategic decisions that reduce the demand on The City s long-term operating budget. The SBP is expected to evolve along with advances in technology and available green building rating systems and tools. By engaging the Office of Land Servicing & Housing with respect to affordable housing projects, IIS has begun the process of reviewing and updating the SBP. Future work will bring together the additional impacted stakeholders to collaboratively review the effectiveness of the existing SBP in meeting The City s sustainability goals. IIS will then bring forward further recommendations to ensure the SBP remains relevant and current. The City continues to demonstrate strategic planning, innovation and fiscal responsibility resulting in a sustainable buildings inventory that passes on economic, social and environmental benefits to future generations.
