Energy Efficiency

Energy Efficiency H1 requirements

The MBIE has updated the Energy Efficiency (H1) requirements for insulating new homes and commercial buildings in the New Zealand building code.

This change has been put in place to reduce the amount of energy required to heat new buildings, to help make them warmer, drier and healthier with less impact on the environment.
