Comfortable temperatures

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

Energy efficiency options explored include photovoltaics, appliances and lighting

Water management

Options explored for water management include appliances, tapware, shower heads, toilets, greywater recycling and rainwater tanks.
