Energy Conservation Week

Design & Technology

Each house received an energy audit and was modeled to determine various energy reduction scenarios. We applied this base model to each home:

Air sealing and insulation
CFL and LED lights
Low flow fixtures (shower head, toilet, aerators)
ENERGY STAR refrigerator and front-loading washer
Gas range and dryer (except in Kitchener).
