![]() ![]() ![]() In most parts of the country, the 6 star standard rating is the minimum to be approved for the construction of stand-alone (Class 1) dwellings. The National Construction Code (NCC) references these star ratings specifying a minimum number of star levels for all new houses built in Australia. In Australia the Nationwide House Energy Rating Scheme (NatHERS) rates the energy efficiency of a home, based on its design using a star rating system (out of ten). This is only about 10% of the energy used in conventional buildings. To gain full accreditation from the International Passive House Institute the total heating and cooling demands of a new build must remain under 15kWh/m²/year. īy implementing the correct design strategies, Passive House buildings are able to achieve an extremely high level of energy efficiency.

Passive House buildings are designed to be resilient to temperature peaks and be comfortable all year round. The concept has been around for approximately 30 years, and is based upon the premise that adopting a few key design principles can enable the creation of buildings with healthy, dry indoor spaces that require little or no heating or cooling. Passive House (from the German Passivhaus) originated in Europe. Passive House design can successfully be implemented in these different climates. In southern Australia the demand is mixed between space heating and cooling, while it is mostly cooling in the central and northern parts of the country. In Australia the demand for heating and cooling is mixed. The first Passive House was built in 1991 by Austrian physicist Wolfgang Feist as a solution to more efficiently heat European homes in winter, but this building concept has been proven to be just as effective to cool down a home in the sweltering Queensland summers as keeping European houses cozy in their harsh winters. Siniat has proudly supported Passive House projects in Australia, including supplying plasterboard to Sapphire House, the first Passive House in Australia built to Bushfire Attack Level Flame Zone (BAL-FZ) regulations (the highest bushfire risk rating) and the SUHO project in South Australia. Passive House is gaining popularity in Australia as a design principle that can offer healthy, comfortable, low energy and resilient buildings. ![]()
