The project uses a combination of passive and active strategies to reduce the energy consumption of the buildings. Key elements include a super insulated envelope, high performance windows and doors, and super-efficient heating and cooling that employ heat recovery ventilation techniques. The overall philosophy is to maximize the efficiency of the envelope so that mechanical systems can be downsized as much as possible.

HERS Score.jpg

Based on early schematic design assumptions, the units are targeted to achieve a HERS score range of between HERS 48 +/- , prior to taking into account the Solar Photovoltaic input.  This means the homes are 52% +/- more efficient than new construction code compliant home. With PV output included, the HERS score for the units are around –5 range +/-.
