We look at each Passive House project starting with a blank page, so far each of our projects are quite different. We don’t create a Passivhaus using any particular formula, we carefully consider what is the most effective manner of achieving performance and comfort based on the finishes the client is looking for, the location and form of the building. 

Other considerations we make include the availability of materials, local trade skills and the project budget. Creating a Passive House in New Zealand in an affordable manner is a challenge in New Zealand. We don’t have a full catalogue of materials available to us and some materials are cost prohibitive as there is poor consumer demand.

Thus we have to be innovative and look for ways we can save on some of elements to help pay for the key elements such as windows.

At eZED we maintain a strong relationship with the industry so that we can keep up with new innovative materials but ensure they are being appropriately applied.
