MBIE has summarised its take on the New Zealand Emissions Reduction Plan. Building for Climate Change (BfCC) will be its tool to make this happen through legislation. We will finally be stepping up to designing for thermal performance (eg operational carbon) and embodied carbon. At Sustainable Engineering, we’re doing our best to lay out a path for this to happen …
First emissions reduction plan heading in right direction on buildings
The long-awaited first Emissions Reduction Plan was published yesterday and media commentators are rushing to dissect it. I liked that the foreword describes the problem as also an opportunity: “a challenge present[ing] the single greatest opportunity we’ve had in at least a generation … It means warmer homes and lower household power bills.” I have three initial observations, specifically on …

Scaling up PH trades training
New Zealand needs more tradespeople, full stop. But we also need tradies with skills and experience of building the Passive House way, especially as larger certified projects get underway. In the UK, a large construction firm developed their own training and to date more than two thousand tradies have earned their “Passivhaus Passport”. This seems to be shorter and more …
