Frequently asked questions

What is passive solar design?
Passive solar design orients and shapes a home to use the sun's position through the seasons — typically placing main living areas facing north (in the southern hemisphere) with eave overhangs sized to let in low winter sun while blocking high summer sun, reducing the need for artificial heating and cooling.
Does passive solar design cost more to build?
Not necessarily — much of it comes from orientation and window placement rather than expensive materials, though features like double glazing or thermal mass flooring do add cost. Ask the builder listed on each plan what's included.
