Passive Houses

A Passive House is a building, for which thermal comfort can be achieved solely by heating or cooling of the fresh air volume required to provide good indoor air quality. Passive House requirements are performance based criteria defining limits to Heating/Cooling loads. Annual space Heating/Cooling demand, air tightness and annual primary energy needs are very critical.

Passive Houses are more and more popular all over the world. Especially in Europe some countries have put forward performance goals for construction that will be close to accomplish Passive House targets. In countries like the Netherlands and Norway, Passive House compliance will become the standard by 2020.

In New Zealand, the Passive House Institute www.phinz.org.nz has been operating since 2011. Stijn Van den Eeden at Prime.design is a Certified Passive House Designer who has been involved in one of the first Passive House designs in New Zealand.

Prime.design offers solutions with aluminium joinery that can be used for Passive Houses. The range of high-tech products vary from high-insulating windows and doors to sliding doors and skylights. With the newest technology even commercial curtain wall systems can comply with the very high requirements. These systems all come with specific solutions that deal with air tightness.

Recent studies in Europe have revealed that on average 25% of energy gets lost through defective air tightness. Reynaers Aluminium has developed not only energy-efficient systems but also a highly-efficient proprietary air tight connection detail to combat this issue.

The REYNACONNECT system consists of several components including a Duo-Foil for the internal airtight connection, a connection profile, stainless steel connection brackets, an exterior swelling tape an elastic PU foam to fill the void between frame and joinery and finally a paste to adhere the foil to the frame. 

PRIME has trained its installers to carefully prepare, install and finish this system to the principles of Building Physics. Prime's proprietary cladding flashing system and the REYNACONNECT take care of all connection details, guaranteeing air tightness, weatherproofing and durability in the most extreme temperatures as well as seismic and coastal areas.
