Wanaka Wedge House
Materials and systems for the Wedge House were selected to meet sustainability targets. A whole-house fan at the very top of the ""wedge" can evacuate heat and pull cool air from the shaded bottom courtyard. The fan was housed in a tightly sealed attic. Air exited the attic space by a weatherproof louvre on the end face of the wedge. Thermal performance exceeds New Zealand standards for a single-family house.

Nundah Apartment Block
This roof mounted fan was installed with a tiled roof on an apartment block with a shared attic space. To comply with fire regulations, the unit had a fire rated tunnel installed from the ceiling vent to the roof penetration.
The goal with this install was to reduce reliance on air conditioning in a home nestled in bushland. A combination of adjustable floor venting was installed here to bring cool air from underfloor during the day then switching to outside air at night.
