Project Profile - ENZO

This net zero, 6-home development by iDEAL Projects is located in the northeast community of Winston Heights-Mountview, just north of the 16 Avenue corridor and serviced by Max Orange BRT. The innovative development consists of four rowhouses and two secondary suites. Designed as purpose built rental housing, the project represents a mix of energy efficiency, low-cost operational living and superior in-home comfort thanks to the improved air-tightness and insulation levels. When fully completed, the development is expected to generate as much energy as it consumes on an annual basis. The development is seeking the Canadian Home Builders Association’ Net Zero Home Label.
