Up-Spec provides data on practical and cost-effective measures to improve the performance of new homes. Specific data is provided across nine New Zealand climate zones, focusing on comfortable temperatures, energy efficiency and water management. The pages here were originally developed when H1/AS1 and H1/VM1 4th edition were the applicable compliance documents for Building Code clause H1 Energy efficiency.

Energy efficiency is about using the least possible energy to perform a task. Reducing energy loss and using passive design elements such as effective house orientation, glazing and insulation can make homes warmer, healthier and cheaper to run.
