It is high time to do something long overdue, implement a Nearly Zero Energy Building performance code

There is nothing in the next round of building code updates around building performance. I know there are politics involved, but all the politics pointed towards this last update before election including something about building performance. Waiting for building code updates is apparently not the way to go about this, we need a ground swell of industry support first and then it becomes easy to adopt as policy.

We’re proposing to pick up on what NZGBC started with the ​Zero Carbon Roadmap​ and give it a stand-alone cause and get voluntary adoption started. This was a pivotal movement in Canada that has created world leading building performance targets. https://energystepcode.ca/​. The end goal of this, is a Nearly Zero Energy Ready building code meaning the application of solar panels and a high renewable grid leads to carbon zero. Just like the Zero Carbon Roadmap spells out.

We ask you to join the Energy Step Code Aotearoa with Primary Energy (ESCAPE) society and get others to voluntarily join in.

There are no exclusions, no loopholes, no categories for different buildings, no climate zones, just one metric: energy use intensity (kWh/m2​/yr).

Total heating and cooling energy:
  • 2020 – 75 kWh/m2​/yr
  • 2023 – 60 kWh/m2​/yr
  • 2026 – 45 kWh/m2​/yr
  • 2029 – 30 kWh/m2​/yr
  • 2032 – 15 kWh/m2​/yr
Total energy use:
  • 2020 – 200 kWh/m2​/yr
  • 2023 – 175 kWh/m2​/yr
  • 2026 – 150 kWh/m2​/yr
  • 2029 – 100 kWh/m2​/yr
  • 2032 – 75 kWh/m2​/yr
