Wānaka, New Zealand
2 Ardmore Street Wānaka Otago 9305 NZ

I combine a love of architecture and design with an understanding of building physics to help create more energy-efficient, healthy, comfortable and durable buildings that are better for people and the planet.

I can work with your design/ build team to create a building energy model and:

  • provide a realistic prediction of energy usage for heating and cooling;
  • identify risk areas with the proposed design (e.g. overheating); and
  • enable informed decisions to optimise your building for comfort and energy-efficiency.
