Occupancy sensors are also utilized in the corridors and other public spaces to turn off the lighting when not occupied." For the mechanical system, a combi- nation of high-efficiency Heat Recovery Ventilators (HRV's) and Energy Recovery Ventilators (ERV's) was used. "Fan power was reduced by using high-efficient ECM motors and ven- tilation air was ducted to each living space for improved air quality," says Tony Pagnotta, principal at Reinbold Engineering Group. Each suite also has independent heating and cooling systems to allow for individual billing. "This ensures accurate billing of energy consumption for heating and cooling. Every ten- ant pays for the energy they use," adds Pagnotta. To meet LEED requirements, high-efficiency natural gas water heaters coupled with low flow water fixtures where also used. For the parkade (on which the build- ings sit), lighting with occupancy sensors has been integrated into each individual light. "As occupants walk through the parkade, the lighting will automatically turn on and off in the area they are in. The entire lighting system conforms to the lighting power density and control requirements of ASHRAE 90.1 [2010]. Another sustainable design was the inclusion of a dual-port electric car charging station to promote the use of electric vehicles," explains Sauer. Outside, the detailed co-ordination of lighting in the central exterior plaza and walking areas provides a beautiful area for families to walk and explore, during the day or night. Klein adds that large planters around the site allow for the growth of sig- nificant trees, "something often not accomplished on a podium space above parking. This will create shaded plazas that will combat heat island and provide refuge from our hot summer climate." By grading up and over the parkade walls, and incorporating dividing planters that also housed the mechani- cal vents, the team was able to create spaces that feel private and yet still afford the site a level of natural surveil- lance by the residents. While the buildings are of course noteworthy and an essential part of this ongoing project, Central Green, which was built on the masterplan created by Ray Letkeman Architects, has achieved so much more, thanks to a great team and close collaboration throughout its development. "This project is as much about the buildings as it is about the creation of the urban realm and the interconnectivity between the build- ings. We have done an exceptional job trying to thread this collection of projects together in order to create a neighbourhood that will provide people a sense of community," says Dagenais.
