BREDEM 8 has been tested against measured consumption data and against simulation models. The testing has addressed both the annual and monthly energy use predictions and the predictions relating to important design issues.
Testing against measured consumption data of the highest quality has confirmed that the model produces overall predictions which are reliable. Testing against simulation models also demonstrates that BREDEM 8 produces overall predictions which are very comparable to those of the simulation models.
In 1989 the "Advanced House" was constructed in Brampton, Ontario as an example of leading-edge energy-efficient and environmentally responsible housing . It is part of Canada's contribution to the International Energy Agency Task XIII Advanced Solar/Low Energy Residential Buildings, which examines innovative methods of reducing residential energy consumption.
