Designing for solar gain

Room layouts for solar gain

To maximise useful solar gains in winter, rooms with the highest occupied hours should be positioned along the south side of the building. Ideally:

  • Living rooms should face South or West.
  • Kitchens North or East.
  • Consider north facing home offices to avoid glare.
  • Bedrooms should be avoided on the West elevations, because these receive solar gain at the end of the day, just before they are occupied, so carry a high risk of overheating.

*Note: with this strategy there is an increased risk of overheating. However, this can be effectively managed with suitable solar shading and prioritising dual aspect.

Design Actions

  • Position occupied rooms to the south
