I recently read an article on Treehugger about the successful completion of a passive house in the south. A passive house you say? What the heck is that?
Passive homes are built without a furnace. They rely on insulation and sunshine to keep it toasty and warm. In the summer they keep cool with a mini air conditioning system and an energy recovery ventilator.
Though you’ll reap benefits in no fuel bills, there are some concerns.
Air quality is among the biggest problems. Since the homes are so well insulated, fresh air will have to be brought in often. Perhaps only a mild concern considering how much will be saved in heating and cooling costs.
