Jeff and Joey’s own home at 6th Street SW has just been featured as a case study in the Mitsubishi Electric website. It is a nice summary of our HVAC system (with a few nice photos too), if that kind of thing interests you. I don’t think we ever officially announced that this house received Passive House certification, which is a quite rare 3rd party environmental building standard in the US, but quite widespread in Europe. Passive House design focuses on the envelope of the building, which is about 11″ in the 6th Street SW house. With double studs, Serious (now Alpen) triple pane windows, and copious amounts of cellulose insulation, our heating and cooling system is quite minimal. We have ductless wall-mounted units on the ground and first floors, and a ducted mini-split on the second floor for the bedrooms. Our house stays exceptionally warm in the winter and cool in the summer. We have a lot of cross breeze in the house as well, through thoughtfully placed windows.
