Chatterton Builders have teamed up with eHaus, New Zealand leaders in the design/build and testing of passive housing. This opportunity adds significantly to the suite of energy efficient options we are able to offer, through years of growing our expertise in the field of better performing homes. This relationship was a natural extension of our drive to provide better housing options for New Zealander’s.
Design build projects under this arm of our business are conducted under eHaus Canterbury. Same team, same expertise, same management….just a different name to reflect the partnership with the eHaus national operation and the specialist work that sets these homes apart*.
Whilst many of our homes are built to principals that increase energy efficiency, comfort and health – sometimes described as passive house principals, they may not be ‘Internationally Certified’ Passive Houses or Low Energy Homes, through home owner choice. However, some home owners want their house to be ‘Certified’, others don’t, but do want to know how their house, & large investment, will perform using the testing and measuring, that is part of the certification process.
Certification is undertaken by the International Passive House Association (iPHA) and requires certain criteria to be reached. House designs are tested against these criteria, and measurements taken (namely air tightness), during the build to ensure houses, which are designed to be passive houses, actually meet the criteria and are able to gain certification. The importance of this testing is that you can see how the house will perform, regardless of whether you are going for certification or not, and if there are any issues with the design or materials proposed, in its unique location, adjustments to the design can be made before its too late.

We moved into our new home a week ago and we can confirm that Passive Houses are good for asthmatics. The asthmatic in our family has noticed a significant reduction in symptoms. No wheezing or coughing and a better night’s sleep.
