Curious to learn more about the Passive House standard and what sets it apart from regular building standards? Start with our FAQs below and contact us if you have any further questions.

Passive House is an internationally recognised building standard that delivers a building that requires very little energy for space heating or cooling.  It is fast being recognised as the highest efficiency standard across the globe.With strong functional knowledge being applied from the start, Passive House integrates building design, building science and construction methodology.There are five major principles to Passive House: insulation – consistently around the building envelope; high performing windows and doors; heat recovery ventilation system; thermal-bridge free design; Airtightness – maximum 0.6 air exchanges per hour.Although these principles are key, in order to achieve the Passive House Standard the energy modelling software must be used called the Passive House planning Package (PHPP). Without this the principles are useless as the final performance of the building is unknown. It is also important to understand that whilst the Passive House principles remain the same across the world’s climates, the details do have to be adapted to the specific climate and conditions at hand. eHaus is a company that understands how to implement the PHPP to provide a certain outcome in each of the 18 New Zealand climate regions. The result is a home that provides a warm and comfortable living environment. The temperature is even throughout the home and operates typically between 20 and 25 degrees, while consuming minimal energy. Passive Houses consume between 75%-90% less heating energy than a conventional house.
