The basic premise is through smart design, and effective use of passive heating, cooling, and day-lighting techniques, buildings can be comfortable year-round in any climate without large, expensive. energy-intensive heating and cooling systems. They can reduce heating energy demand by 90%.

It's sometimes hard for people to imagine how we could meet global energy demand only with renewable energy -- a big part of what makes that possible is dramatically reducing the amount of energy we use (without reducing quality of life -- and indeed increasing it for a great many people). Passive House design is an exciting way to make that happen.
