Passive house near Christchurch,
New Zealand

This single-family passive house was completed in 2019 in Ohaka, just north of Christchurch. One of the aims of this project was to demonstrate that a home that meets passive house standards is achievable for first-time buyers in New Zealand. The house’s simple geometry and moderate size (166 m² TFA, excluding the detached double garage) helped the building meet Passive House energy targets.

The windows were produced on South Island using European glazing. The southerly location in New Zealand, with low sunshine hours in winter and a temperate oceanic climate, meant triple glazing was required – in this case, with low-e coating and argon fill.

Christchurch experiences cold winters, but a small panel heater sized for a bedroom is providing all the additional heat they need to keep the whole house comfortably warm
