Property Council recently submitted on the Building Code Update 2021 and Operating Protocols.
While we support the intention of the Ministry of Business Innovation and Employment (MBIE) to ensure buildings are more energy efficient, there are parts of the update that require clarification and further refinement. This includes:
- refinement of the proposals to ensure its alignment with the Building for Climate Change recommendations (including proposed set of criteria for operating protocols) and the Healthy Homes Guarantee Act 2017;
- provision of further details around proposed options (including construction costs) for energy efficiency for large buildings, housing and small buildings;
- as well as adoption of a method of compliance with the Building Code with clear indication of whether it is mandatory.
We also recommend that MBIE refine the Building Code update 2021 taking into consideration other factors that contribute to building efficiency (e.g. condensation and overheating risks; other cost-effective means, such as improving airtightness, improving heating system, setting up mechanical ventilation to remove foul, moist or warm air); different insulation requirements for different buildings as well as prioritisation of significant issues (e.g. leaking buildings) over their current proposal of increased natural light.
