High Performing Buildings - Fall 2011 - (Page 51)

argon-filled glazing, and a doubling of insulation values over code requirements (average of R-29 for walls and R-40 for roof), the project significantly reduced heat gains and losses compared to a baseline building. Operable shading devices were also used to limit south and west solar heat gain. The supplied shades are designed to automatically retract during a windstorm to ensure that the fabric does not get damaged. The buildings use two condensing 90.5% efficient boilers as backup to the district energy plant. Boilers were initially installed as the project was completed before the construction of the district heating system. The exhaust air from the washrooms is centrally exhausted through a heat recovery wheel with an effectiveness of 81%. There is no vapor-compression cooling equipment, but a four-pipe fan coil system using domestic hot water (DHW) for heating, and domestic cold water makeup for summer cooling preheats the DHW. While this system does not provide year-round cooling, a system to chill water could be added for a full cooling system. In winter, the district heating system provides all DHW. A reduction in overall lighting power density (average of 0.6 W/ft²), and use of ENERGY STAR labeled appliances throughout, contributed to overall electrical savings.

Dockside uses bioreactor tanks and filter membranes to treat all sewage on-site, making it virtually drinking water quality. Treated water is used for irrigation and flushing of toilets, reducing the project’s potable water consumption by 67%. Synergy received all Energy + Atmosphere credits under LEED NC Canada.
