Announced in the eHaus winter 2019 newsletter:
“We noted, with interest, the Waikato expoHaus today registered 19.5 degrees inside as the staff arrived for work, with an outside temperature of just 4 degrees. There was also no heating used over night! We get excited imagining when PassivHaus becomes the NZ minimum code, allowing all Kiwis to thrive in warm, healthy homes.”
