Solar greenhouses use a variety of features such as double glazing, insulation for non-glazed exterior surfaces, added thermal mass, and passive ventilation systems to reduce or eliminate the need for backup heating and for powered ventilation.
Andrew's design incorporates all of these, and he provides some summer and fall temperature and humidity logs to show how the greenhouse is doing.
