Okanagan College Daycare – Passive House (2016/17)


The Okanagan College Daycare project is seeking Passive House Certification, with specific focus on reducing primary energy consumption and improving occupant health and comfort.

The building envelope designed by LandformADB and constructed by Ritchie Design Build provides the most energy efficient barrier between the indoor comfort and external extremes of -20°C to +40°C.

BC Building Science carried out the Passive House envelope tests, supported by Certiphiers group.

Archineers provided the integrated design services to assist with securing a night cooling and natural ventilation strategy, along with mechanical systems design including PHI approved HRV, Air sourced heating and cooling, Earth Tubes and Hybrid Heat Pump Hot Water heater.

The building will be Net-Zero energy through the addition of Photovoltaic solar cells fixed to the south facing roof. Water efficiency is also being encouraged through rainwater capture and reuse.
