Revolve provided green building consulting and energy modelling services for this 12,700 m2 (136,000 ft2) seniors home in Edmonton. One of Revolveās first tasks was to provide preliminary energy modelling and to help optimize the building design. In addition to the base model and systems, 5 additional envelope and 5 HVAC scenarios were investigated. The energy savings and lifecycle costs of each scenario were calculated which allowed the building owners to choose the most cost effective way to reach their energy targets. The energy models used in the optimization runs will also be used to demonstrate NECB 2011 and LEED compliance.
