2 May 2013 — A “High Performance House”, now on show in Christchurch where 10,000 homes faced demolition after the 2011 earthquake, could help housing needs.
The pre-fabricated home, means, in theory, home owners could pack and leave their damaged homes on Monday, demolition and removal would be done on Tuesday and Wednesday and on Thursday the foundation would be prepared.
The house to be delivered on site the following Monday or Tuesday.
The High Performance House is constructed with a new system called Warmframe.
Warmframe is an innovative new building system which combines steel framing, insulation and windows into a single unit, built off-site and which is much better insulated than Building Code minimums. Claddings and coatings can also be added in the factory.
It was developed by industry partners – New Zealand Steel, Frametek-RFS, InsulPro, Fletcher Aluminium and Resene.
The house was designed by architect Anne Salmond. Other features include photovoltaics for energy generation, solar water heating, a wood pellet burner and a rain water tank.
Canterbury Earthquake Recovery Authority chief executive Roger Sutton said off-site manufactured houses such as the High Performance House could fill a real gap in the Christchurch rebuild.
New Zealand Steel marketing and sales vice president Scott Fuller said because of the speed of offsite fabrication in a controlled and secure environment with no weather delays it was ideal for Canterbury rebuilds.
“A faster build causes less disruption, allowing people to continue to live in their old homes throughout the construction period. Other accommodation will only be required whilst the site is cleared and the house is delivered and assembled.”
The February 2011 Christchurch 6.3 magnitude earthquake killed 185 people and caused widespread damage across Christchurch, especially in the central city and eastern suburbs.
Many buildings were already weakened by the 4 September 2010 earthquake and its aftershocks.
