Welcome to Level.
The authority on sustainable building.
Level will help you design and build homes which have less impact on the environment and are healthier, more comfortable, and have lower running costs.
The new Building Code requirements for energy efficiency in new houses have already come into force for the South Island and the North Island up to the Franklin and Thames-Coromandel districts. They apply to the rest of the North Island from 30 September. Level has useful background explanations on insulation and glazing.
