“It’s like watering a garden with a leaky hose filled with holes,” he said. “We can turn on more water, but what’s the point if we don’t stop the leaks?”
Eagles said that after what happened on Friday morning, there would be “a lot of talk about new electricity generation. It’s vital that actually we look at one of the major causes of [Friday] – cold, inefficient housing”.
He said the Government should commit to a major retrofit programme similar to those being done in Ireland, Australia and the US.
“Research from Otago University shows if we built to best-practice standards, as the majority of the OECD already are, we could reduce the winter peak by 75 per cent. That’s huge, and not only takes pressure off the grid, but would be a massive win for New Zealanders’ health and cost of living.”
The 2021 research, by associate professor Michael Jack, found the reduction from building better homes was so dramatic, that despite predicted growth in floor area and achieving healthy temperatures, the winter peak in 2050 would be less than the current peak.
Ahead of last year’s election, the Green Building Council was one of 170 organisations from across Aotearoa that called for politicians to commit to a major retrofit programme to tackle the state of New Zealand homes, he said.
“This is what most of the OECD is doing, investing in healthier warmer homes, making their grid vastly more efficient.”
Eagles said the Institute for Energy Economics and Financial Analyisis in Australia has just published similar research to that of Otago University’s.
“Rather than mining for more gas, a more financially prudent approach is to lead with demand reduction.”
