Shades of Green: the 1970s vs. the Millennial Generation

The Millennial generation approaches design from the presumption that central air conditioning is normal and necessary

Posted on Nov 13 2012 by Vera Novak

Recently a friend asked for help in designing an off-grid house. Interestingly, I pulled out the old books from the '70s to show as examples and inspiration. We tagged a combination of ideas: an earth berm house, a passive solar house, an attached greenhouse buffer space, a solar thermal system, and a stack effectAlso referred to as the chimney effect, this is one of three primary forces that drives air leakage in buildings. When warm air is in a column (such as a building), its buoyancy pulls colder air in low in buildings as the buoyant air exerts pressure to escape out the top. The pressure of stack effect is proportional to the height of the column of air and the temperature difference between the air in the column and ambient air. Stack effect is much stronger in cold climates during the heating season than in hot climates during the cooling season. heating/cooling system incorporating a heat sinkWhere heat is dumped by an air conditioner or by a heat pump used in cooling mode; usually the outdoor air or ground. See air-source heat pump and ground-source heat pump. (southern rock exposure) and a cool northern forest glen.

It all seemed so — natural …
