World Green Building Week

World Green Building Week is 2125 September.

A number of online and in-person events are planned around the country. They include webinars, panel discussions and Green Campus Days on universities.

Topics will include:

  • Social procurement: a massive untapped green game changer?
  • Are we on the cusp of a healthy buildings revolution? Wellbeing, workplaces and the new normal
  • MBIE: Building for Climate Change
  • Is the financial services industry doing enough for a healthy, green Aotearoa?
  • Shovel ready. Can it ever work?

Government details steps to cut new build emissions

Two new documents set out proposals for cutting greenhouse gas emissions in construction.

The documents Transforming Operational Efficiency and Whole-of-Life Embodied Carbon Emissions Reduction were published by the Ministry of Business, innovation and Employment (MBIE) as part of its Building for Climate Change programme.

In the operational efficiency area, proposals for new buildings include:

  • Defined indoor environmental quality parameters that all new buildings must comply with (temperature, humidity etc.).
  • A mandatory Operational Emissions Cap setting out the total allowable annual emissions per square metre per annum for all new buildings.
  • A mandatory Water Use Cap setting out the total allowable potable water use per square metre per annum for all new buildings.
  • These two caps will tighten in a series of steps, reaching a final cap by 2035. The Cap for fossil fuel combustion emissions will be reduced to 0 by 2035.

MBIE plans to provide an online modelling tool for small buildings (up to 3-storey, 300m2 floor area) that will generate the reports required for compliance at building consent application and code of compliance stages.

With regards to embodied carbon in building materials:

  • Initially, whole-of-life embodied carbon of buildings will be required to be reported as part of the building consent process.
  • At a later stage buildings will also be required to meet a mandatory cap on their whole-of-life embodied carbon in order to obtain a building consent.
  • The cap will be tightened in a series of steps.

It is proposed that on-site renewable energy generation and storage is outside the scope of the framework.

Submissions on the documents close 30 September.

Solar generation growing but below global levels

Residential connections are growing but are still a tiny proportion of electricity generation.

The figures come from the recently released Energy in New Zealand 2020, produced by the Ministry of Business, Innovation & Employment and providing details about the 2019 calendar year.

Solar generation increased by 27%, from 99 GWh in 2018 to 126 GWh in 2019. Solar PV accounted for just over 0.3% of total electricity generation in 2019. The growth in solar photovoltaic (PV) uptake for electricity generation in New Zealand is lower than it is globally. Residential connections account for 80% of existing solar PV capacity.

Among other findings in the report:

  • Residential electricity use remained stable in 2019.
  • Average electricity costs faced by the residential sector did not change significantly over 2019. The nominal residential cost in the December quarter of 2019 was 0.6% higher compared to the 2018 December quarter.
  • Wind provided 2,232 GWh of electricity, or 5.1%, of total electricity supply in 2019. This was up 9.1% on the 2018 level.
