The guidelines we developed in the Waitakere NOW Home were further tested in a collaboration between Beacon and the New Zealand Housing Foundation, a charitable trust dedicated to assisting low-income households into their own homes.
A standard Housing Foundation design was amended using Beacon’s guidelines and with advice and guidance from Beacon’s research team.
A family of six lived in the house while it was monitored for temperature and humidity. Their feedback and the monitoring results provided valuable information for future NZ Housing Foundation homes.
- The HomeSmart Home was an exceptionally low energy home, using only 3980kWh per year.
- The improved thermal envelope reduced heating requirements, and energy draw, to virtually nil. A portable electric heater and the lounge inset heater were used initially to keep the newborn baby warm, but subsequently the heaters were not used at all.
- The photovoltaic system generated nearly a third of the electricity used in the home, about 2000kWh per year.
- The HomeSmart Home was warm and healthy in winter with an average 19°C in the living room, and 18°C in the bedroom.
- However, in summer, the home tended to be too hot, especially upstairs.
- Water use in the home was modest at an average of 117 litres per person per day.
- The greywater system reused about 30% of the total greywater produced by the household.
