So here’s the deal:
- Passive solar design optimises the design of your house to capture energy from the sun. It is not by itself an adequate measure to deliver a comfortable low energy project.
- The PassivHaus standard uses Passive solar design in conjunction with techniques that minimise heat loss. This ensures that solar energy goes further towards heating your home.
- The PassivHaus standard is also beneficial if you have a site with less than perfect sun, as low heat losses make it easier to heat your home from other sources of energy.
