ENERGY EFFICIENCY

Heating, Cooling & Ventilation

PHOTO: WHW/Craig Mosher

2 air source pumps condition the building. The heat pumps have a heating and cooling COP of 3.11 and 2.90.
Each of the ventilation systems is equipped with a heat recovery ventilator with effectiveness between 0.26 and 0.68.
Four flat plate panels pre-heat domestic hot water, resulting in a 36% reduction in the energy demand for that purpose.

Building Envelope

Roof

2/3 green living roof – Average R value 34 (RSI 6)

Walls

All insulation outboard of sheathing, continuous insulation plane over foundation wall, minimizes thermal bridge. Average R value 25 (RSI 4.4)
Locally quarried stone (<100km from site) and Nova Scotia harvested hemlock used for cladding

Windows

Thermally broken aluminum frames; low E, argon- filled sealed units (U 2.63W/m²K) or “Solera T” (U 1.14 w/m²K) glazing units
Glazing constitutes 18% of wall area

Solar Shading, Daylight & Lighting

PHOTOs: WHW/Craig Mosher

The building design provides daylight to 85% of regularly occupied spaces and direct lines of sight to perimeter glazing in 92% of regularly occupied spaces.
Interior and exterior artificial lighting designed to reduce light pollution and to preserve a dark sky.
Interior lighting designed to ensure maximum candela from each interior luminaire
