    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.

    We all want a warm, comfortable home, but many New Zealand houses are difficult and expensive to heat to healthy temperatures.

    Around 35% of the energy used in the average New Zealand household goes on heating your home. If your home doesn't have adequate insulation (like the majority of our homes), a lot of your heat is just wasted.

    Improving your home's ability to keep in the heat and smart use of a clean, efficient heating system will make your home more cost-effective to run and warmer and healthier to live in.

    Repairs to earthquake damage on your home through the Canterbury Home Repair Programme can expose hard-to-access areas like wall cavities, skillion or flat roofs, and suspended floors, creating the opportunity to install insulation. 

    Although you will need to pay for any insulation being installed that wasn’t there before the earthquake, the repair process is a great opportunity to get insulation fitted into these places that are normally tricky to access.

    There's no better time to think about energy efficiency than when you're building or
    renovating. It is when you can go back to the drawing board to really incorporate energy
    efficiency into your design.

    For little or no extra cost, you can create a home that's warmer, more comfortable and more
    cost-effective to run for years to come - and you don't have to compromise on style to do it.

    Designing for energy efficiency also means your home will use less of the world's energy
    resources, so you'll leave a better legacy for generations to come.
