1.1 Passive Solar Gain

 

This form of energy is often taken for granted; sunlight enters a building through windows, and warms the inside. In an average house in the UK, passive solar gain contributes 14% of the heating demand.

Thoughtful design can improve this figure further with very little, if any, increase in the cost of building the property:

  • Orienting the house so that the more often used rooms face south;
  • placing larger windows on the south side, and smaller on the north;
  • using building materials that store heat by adding “thermal mass” to the house and
  • laying out housing so that buildings do not over-shadow each other.
