The project brief was to design a CertifiedPassive House on a sloping site in Drumderry. The dwelling is approached frombelow. This family Bungalow achieved Passive House Certification and the Bungalow also has a Irish BER of A1 @ 6.73 kWh/ m2/ yr (Audited result).
This is a single storey family house located in the Irish countryside. The design is contributing minimal impact on the surrounding landscapes, taking advantage of natural daylight and optimising the free heat from the sun.

If you had to do it again?
The builder was not used to building low energy dwellings. He was a good builder and needed quite some tutoring. Some of this torturing should have been done earlier in the build.
Building users opinion
We wanted and got a Passive House. The design works well and comfort levels are high throughout the Year.
