Up-Spec provides data for a range of performance improvements for new homes
Improvement options cover comfortable temperatures, energy efficiency and water management
Specific data is available for nine climate zones
Up-Spec provides actual data for a range of performance improvements for new New Zealand homes across three themes: comfortable temperatures, energy efficiency and water management.
Figures are available for simple performance upgrades in nine climate zones across New Zealand: Auckland, Hamilton, Tauranga, Napier, Wellington, Nelson, Christchurch, Dunedin and Invercargill.
Many opportunities are available for most new-spec (volume-build) homes to improve their year-round comfort and reduce additional heating and cooling needs.
Energy efficiency options explored include photovoltaics, appliances and lighting
Options explored for water management include appliances, tapware, shower heads, toilets, greywater recycling and rainwater tanks.
The Up-Spec performance upgrades are based on independent research by BRANZ and were developed in consultation with the homebuilding and environmental advisory community.
