Many Build columns and stories focus on specific research and how BRANZ’s work is helping to create a building system that delivers better outcomes for all. What is perhaps less visible is any position BRANZ takes when it comes to issues of critical importance to achieving that mission.
Our research is deeply valued
We have learned through engagement with industry that BRANZ’s independence and research are deeply valued. However, the industry has also been clear that it wants us to use our independent scientific expertise to inform public discussion.
In short, BRANZ needs to do a better job of promoting that evidence and using it to support a clear, independent position or recommendation where appropriate.
I’m reminded of a comment in a recent survey that sums up the industry view: ‘We’d really like BRANZ to step up and say, here’s the evidence, here’s the data, here’s the rationale and here’s what’s needed to effect change across the entire industry.’
Speaking up on affordability
We’ve listened. BRANZ is increasingly promoting its evidence-based position on industry issues and opportunities, particularly regarding proposed policy changes to housing affordability.
For example, BRANZ has taken a position on overseas building product approval processes in response to the government’s proposed change in policy to address building affordability.
Recognising the value of introducing a more efficient process and the need for additional quality building materials in the market, BRANZ has supported the proposed change, noting that the emphasis should always be on quality:
- Ensuring product assessments are evidence based.
- Minimising any unintended consequences by identifying both lower-risk and higher-risk product categories – for example, internal insulation (lower risk) versus exterior roofing products (higher risk).
- Ensuring that higher-risk products continue to be specifically tested in the New Zealand environment to perform appropriately in our unique conditions.
Ensuring the facts are heard
More recently, BRANZ has reinforced support for higher energy efficiency standards and is encouraging the sector and government to retain the updated H1 standards introduced in 2023.
The science does not support the theory that the impact of H1 standards on homes causes overheating due to increased insulation. BRANZ has noted:
- the updated H1 standards are based on scientific evidence
- contrary to popular misperception, insulation does not cause overheating
- overheating is the result of poor design rather than better insulation
- the costs of reversing the H1 changes can be avoided
- the new H1 standards help align the building sector with national climate goals.
BRANZ has delivered and identified research that confirms energy-efficient homes have lower lifetime costs due to smaller energy bills. In addition, BRANZ continues to support the industry to identify cost-effective ways of delivering the H1 requirements without reducing insulation standards that improve our built environment and our lives.
Data and experience counts
In a third recent example, the government is progressing a requirement for building consent authorities (BCAs) to use remote inspections as the default approach so building a home is easier and cheaper. A public discussion paper has been released.
BRANZ will contribute meaningfully to this discussion and make public any submission. Our position will be based on the considerable data and scientific expertise we have generated through the development and implementation of our free remote inspection app Artisan, which is already used by many BCAs.
Leading from the front
BRANZ is in a unique position to add valuable, fact-based insights on the widest range of industry issues. Going forward, where we have the evidence and facts to lead discussion and support decision making for the benefit of Aotearoa New Zealand, we’ll continue to share our expertise and have a say.
