Do I have to have lots of north facing windows for the Passive House to work?

Not necessarily. Sure enough, it is ideal to have north facing windows to harvest the free energy provided by the sun. However, it is also possible to achieve the Passive House standard if your site does not lend itself to maximising solar gain (but you will probably have to compensate for this with additional insulation). All designs have to be tested and verified in the Passive House Planning Package (PHPP) software. If you have a wonderful view from the southern side of your house, you needn’t deny yourself of this. The Passive House is not as rigid as many people think, particularly in the Australia’s moderate warm to temperate climate.
