Four techniques and examples of building sustainably in NZ

The business case for sustainable building in New Zealand is clear: The increase in cost for green construction materials is repaid five-to-six times over in 20-years, and it increases building value - especially for offices - as much as 40 per cent. Both of these figures are from the Ministry for the Environment and highlight the cost-saving, money-making benefits builders and architects could offer their clients by consciously considering green construction products and methodologies.

While no longer a niche market here in New Zealand, the sustainable building still presents an opportunity for builders and specifiers to enhance their skills, differentiate from competitors and help the environment in the process. It also is very tangible for many homeowners with easily accessed online resources such as Homestar; a comprehensive, independent national rating tool that measures the health, warmth and efficiency of New Zealand houses.

But where to start? These four examples show off some of the nation's best building techniques and ideas. While no longer a niche market, sustainable construction is still an opportunity for builders and specifiers to enhance their skills.

Hobsonville Point is a 167-acre medium density development on the shores of Auckland's Waitemata Harbour and was rated a very high sustainability neighbourhood by the Beacon Pathway Observational Tool and Resident Self-Report Tool.

This picturesque Auckland community ranks in our list because it shows that sustainability comes not just from individual units, but from the interconnected whole. Hobsonville Point is designed so that residents have easy walking access to a number of important facilities, and indeed 86 per cent of locals reported using one of their local parks in the month prior to being questioned, and 90 per cent had visited their local farmers' market.

The area also has a high concentration of renewable energy sources, and its streets are designed to maximise solar access for most dwellings while simultaneously discouraging fast driving.

• Key takeaway: Green building isn't just about using better concrete or planting more, but rather taking a holistic approach to community design that reduces residents' needs to rely on fossil fuels, and maximises their personal well-being and safety.
