The Waitakere NOW Home was designed to show that a warm, dry, healthy, water- and energy- efficient, and affordable home could be built using materials and products available at the time (2005).
A family lived in the house while it was intensively monitored. Temperature, humidity, how much water and energy was used and where, and liveability were all assessed.
- The house was very warm to live in and the family only used a heater and electric blanket on a handful of days in the year
- The living room and bedroom reached World Health Organisation recommended temperatures for good health
- The family used 33% less energy than an average similar household and 45% less than in their previous house
- The family used half the average water use in Waitakere City
- The 13,500L rain tank supplied 47% of the home’s water needs in year 1, and 52% in year 2.
- The solar water heater provided 55% of hot water needs.

Beacon’s first live research home still outperforms many new homes today
BRANZ research found the Waitakere NOW Home had better thermal performance (warmer, more comfortable, requiring less heating) than 210 homes consented in 2016.
