130 COSTS OF GREEN BUILDINGS
PLATINUM PROJECT PROFILE
Vento Residences, Calgary, Alberta
Designed by Busby Perkins+Will, this 38,750-square-feet (3600-square-meter),
three-story mixed-use project includes retail, underground parking, and 22 resi-
dences (including two affordable housing suites). A 45 percent reduction in
energy derives from an enhanced building envelope; improved insulation levels;
double-glazed, argon-filled, low-e windows; exhaust air heat recovery ventilation;
and lighting occupancy sensors. The energy cost performance of the Vento
Residences is 47 percent better than Canada’s Model National Energy Code for
Buildings. Dual-flush toilets, low-flow fixtures, and rainwater reuse contribute to
reducing potable water use by 50 percent.*
