Through the City’s Sustainable Building Policy, all new City-owned buildings and major renovations are designed and constructed to achieve Leadership in Energy and Environmental Design (LEED) Silver Certification as a minimum. Established in 2008, the policy ensures facilities like the Terwillegar Community Recreation Centre are built to an environmentally sustainable standard that benefits all Edmontonians, now and in the future.
The LEED rating system is recognized as the international mark of excellence for green building in more than150 countries. In addition to LEED certification, City facilities are also built to achieve at least 30 per cent higher energy efficiency than the current National Energy Code of Canada for Buildings.
The guidelines for achieving LEED Silver Certification provide the framework to design buildings in a way that reduces costs and increases energy efficiency. This includes designing mechanical and electrical systems that are energy efficient and selecting windows that will balance a need for natural daylight and views, while minimizing energy loss.
There are many ways the LEED prerequisites and credits help reduce the environmental impact of the City’s buildings, including:
- Energy and Atmosphere:
- Minimum Energy Performance: reduces the environmental and economic harms of excessive energy use by achieving a minimum level of energy efficiency for the building and its systems.
- Optimize Energy Performance: achieves increasing levels of energy performance beyond the prerequisite standard to reduce environmental and economic harms associated with excessive energy use.
- Indoor Environmental Quality:
- Daylight: introduces daylight into the space, which reduces the use of electrical lighting.
- Quality Views: gives building occupants a connection to the natural outdoor environment by providing quality views.
Once facilities are operating, the City works to ensure facilities achieve a balance between energy efficiency, environmental sustainability and growth. The Office of Energy Management is responsible for enhancing energy performance to help reduce the City’s Greenhouse Gas (GHG) footprint. It achieves this through a number of ways, including using the sun (solar PV and solar thermal energy), biomass (waste management) or using ‘greener’ sources of energy such as natural gas to generate electrical power and heat.
These programs all support the City’s The Way We Green strategy, which strives to make Edmonton a more sustainable and resilient city. To read the full article go to my resources page and select ARTICLES....
