Description

Complying with the new requirements of clause H1 (the rules for thermal performance in housing in the New Zealand Building Code) for windows follows the previous process implemented in 2022 and 2023, but the insulation values are higher.

In the future, designing homes to reduce space heating and cooling needs will likely use a modelling method to determine their designed thermal performance. This will ensure that the best choices can be made to maximise the benefits of solar gain through glazing and minimise energy and carbon used for space heating and cooling with clever design.
