The New Zealand Green Building Council (NZGBC) welcomes today’s Government announcement to simplify rooftop solar installations and create a fast-track consent pathway for sustainable buildings.
Chief Executive Andrew Eagles says these reforms recognise the growing importance of energy efficiency, water conservation, low-carbon construction, and climate resilience in New Zealand’s built environment.
“This is a positive and practical step that will help more New Zealanders benefit from renewable energy and more efficient homes,” says Eagles. “Reducing red tape and acknowledging sustainability in the Building Act is a signal that smarter, more resilient buildings are a national priority.”
Eagles says it is vital that the upcoming definition of “sustainable buildings” is backed by clear, consistent, and measurable performance criteria that are trusted by industry.
“We have tried and tested tools already in the market — such as Homestar — which have been helping builders, developers and homeowners deliver warm, efficient, low-carbon homes for over a decade,” he says. “Aligning these new Government pathways with existing, proven standards like Homestar will provide confidence, consistency and accelerate real change.”
There is also mounting evidence that this makes financial sense. Major banks are now actively offering low-interest options for mortgages and developer finance for homes designed to Homestar standard. “Banks get it. Developers get it. Efficient homes mean lower operating costs for homeowners, potentially providing relief for soaring energy bills,” says Eagles.
He adds that it is good to see both solar generation and sustainable buildings reflected in the announcement.
“A truly sustainable building doesn’t just generate its own energy — it uses less energy in the first place, it makes the best use of water, and is designed to withstand a changing climate,” says Eagles. “That is good for all New Zealanders and also helps deal with our energy crisis. We look forward to working with MBIE and the Government to ensure the new framework delivers on this.”
“This announcement is a great step forward — now let’s make sure it leads to the best possible outcomes for Kiwi homes, communities, and our climate.”
