(See Choose the Low-Hanging Fruit by Lechner.) In this issue we focus on passive solar heating techniques.   Most passive […]

Indoor Air Filtration with Plants

As I’ve been learning about passive solar retrofits, I’ve also learned that when a home is better insulated, while it can make the energy systems more efficient, the quality of the indoor air can become more of a concern. For example, when drafty windows are replaced, the home can become more energy efficient, yet an […]
