The Passive House standard
Passive House is an international energy performance standard with around 30,000 projects certified by the Passive House Institute (PHI) across a range of countries and climates (including New Zealand).
The core focus of Passive House is to dramatically reduce the requirement for space heating and cooling, whilst also creating excellent indoor comfort levels. This is primarily achieved by adopting a fabric-first approach to the design through specification of high levels of insulation to the thermal envelope, exceptional levels of airtightness and heat recovery ventilation. Good solar orientation assists in meeting the required performance level in a Passive House, but is not essential.
Energy Architecture NZ Ltd has two categories for new build projects and one for refurbishments projects.
All categories involve energy modelling using specialist software, Passive House and EnerPhit standards involve third party certification of the performance.
Annual heating demand figures are indicated under each category.
