How can you make a difference?
Your choice of building materials can make a difference. How much CO2 will be emitted during the manufacture of your building materials?
How will the building materials that you choose govern the energy consumption of your new home?
We advocate the use of magnum board (for RAB and wallboard) paired with wool insulation.
Magnum Board produces less greenhouse gasses during manufacture than mainstream wallboard.
According to Health Based Building, as a finished product, Magnum Board is negative CO2, meaning the product absorbs CO2.
Magnum Board provides enhanced airtightness without relying on plastic wraps, so this makes your home a better choice all-round.
This combination of building materials provides enhanced energy efficiency, so you will save while using less energy.
There are many other factors that will help you achieve a lower CO2 home. Contact us to learn more about how you can build a better future for your family and for our planet.
Our environmental crisis
The Intergovernmental Panel on Climate Change released a report in April 2022. Without immediate action, limiting global warming to 1.5°C is beyond reach. The 1.5-degree limit was agreed in Paris in 2015.
The following month we learned that parts of New Zealand are subsiding, so the average sea level rise of 3.5mm per year could be effectively doubled,

Sea level rise is caused by thermal expansion of the ocean, melting glaciers and by melting of the ice sheets. Because parts of our land are subsiding while the sea is rising New Zealand will feel the effects sooner than many.
It’s now or never to limit global warming to 1.5 degrees.
Home building contributes to the cause
Carbon pollution is the major driver of climate change. Even though water vapour is the most significant greenhouse gas, scientists have found that carbon dioxide (C02) controls the amount of water vapour in our atmosphere.
The building and construction sector is a significant contributor to greenhouse gasses. Greenhouse gasses are emitted when building products are made, when buildings are constructed, and when in use.
Worldwide, in 2017, the construction and operation of buildings accounted for 39% of emissions. According to The New Zealand Green Building Council, emissions from the NZ construction industry have increased by 66 percent in the decade from 2007 – 2017.
20 percent of New Zealand’s carbon footprint is created by our built environment. If New Zealand is to achieve its climate change goals including net zero carbon by 2050, then the construction sector and clients must make change.
