Our model homes are designed to meet the Passive House standard using a raft slab foundation. An optimal site is relatively flat with good access to free solar energy from the sun. The south facing wall should be oriented within 20 degrees of solar south. We can meet the Passive House standard even if these requirements are not meant by adjusting the insulation levels in the slab and roof and adjusting the glazing ratios and glazing specifications.
