What is sustainable building?
By the 1980’s environmental problems were becoming global in scale and in 1987 the Brutland report used the term ‘Sustainable development’. The aim of the Brundtland Commission was to help direct the nations of the world towards the goal of sustainable development.
In simple words, sustainability means meeting our own needs without compromising the ability of future generations to meet their own needs. In addition to natural resources, we also need social and economic resources, so health is part of sustainability.
The basic objectives of sustainability are to reduce consumption of non-renewable resources, minimise waste, and create healthy, productive environments.
Sustainable design seeks to reduce negative impacts on the environment, and the health and comfort of building occupants, so improving building performance is key.
What is the current situation in New Zealand?
Thirty-five plus years on, we find the building industry in New Zealand at large, has apparently ignored the need for sustainable development.
We don't accept that this is good enough
Inside this wheelbarrow is all the waste from the frames we built on site (pic above). We’re actively working to minimise our waste.
Our Foreverbreathe homes are built to 2.6 – 3 ach, not too tight, just right. This effectively halves the amount of energy required for heating and cooling in comparison to a new home built to code.
This improved airtightness is achieved without the use of plastic wraps and internal moisture is managed to the right degree – creating a healthy environment and a long-lasting structure.
The components of the Foreverbreathe wall system are very low toxin. When in use, the wall system will work to filter toxins rather than to add to them. The system has been advocated by the Asthma Society under it’s Sensitive Choice label – well worth exploring if someone in the family suffers from a respiratory system disorder.
A key part of the Foreverbreathe wall system is wool insulation. Wool works naturally to make your home more comfortable in both winter and summer – just like it does when you wear it. The R value of your wall system can be increased by upgrading from 90mm thick walls to 140mm thick walls, should you choose.
