Energy efficiency and heating your home

This page identifies ways to improve new house design to ensure a house uses the heat from the sun more effectively.

All New Zealand houses are heated by the sun to some degree, but some are better at using the sun's heat than others. 

Designing your new house to include passive solar design principles will:

  • keep your home warmer in winter and cooler in summer;
  • help improve insulation;
  • reduce dampness and condensation;
  • save you money on power bills;
  • reduce air pollution locally.
