Guide to smarter insulation

As a nation, we are committed to using energy wisely and efficiently. As a New Zealander, you can do your bit to help. Improving the energy efficiency of your house means both lower power bills and a warmer, more comfortable home.

Much of the energy we use in our homes and buildings is wasted or could be reduced. Produced by the Department of Building and Housing, this guide provides detailed information on initiatives to reduce energy use in new homes and buildings.

From 31 October 2007, there are new minimum standards for insulation in every home built in the South Island and Central Plateau of the North Island. In most instances, this will mean the use of double glazing.

After 30 September 2008, all new New Zealand homes need to meet these new insulation standards, resulting in these homes using about 30 percent less energy to stay comfortably warm.

All major extensions to existing homes will also need to meet the new insulation requirements.

From 31 October 2007 there are also new minimum standards for lighting in commercial and other large buildings.

This guide provides technical details to assist builders, designers and others who are building or renovating.

Some cost is added to a new home by new insulation requirements. See how these costs are more than met over time by reduced power bills in a new, more energy efficient home and building. There is a payback to your pocket, New Zealand and the planet.
