This attached solar greenhouse is designed for the Rocky Mountain (8,000 Degree
Day) climate. It provides about 100,000 BTUs per day to help heat the house,
as well as the 300 sq. ft. of floor space for growing plants. It is a 2X6 wood
frame structure with a large glass facade (210 sq. ft.) aimed at the winter
sun. The glass is insulated at night by a Beadwall system to help maintain minimum
air temperatures of 55F degrees.
A small fan moves hot air out of the greenhouse and into the main house delivering
heat and humidity on clear winter days. The fan is necessary to prevent temperatures
in the greenhouse from climbing over 90F at mid-day. Barrels of water stacked
two high along the north wall for thermal storage rise about 15F degrees on
a sunny day. They store heat for night time use, preventing daytime overheating.
Glass is tilted 58 degrees to the horizontal to gain maximum
solar aperture at this site. It has to be shaded by exterior curtains is the
summer. The 350 cfm fan brings heat in winter to the house, dropping 15F before
it returns to the greenhouse through an existing door. Summer ventilation is
by roof ventilator and by cross-breeze through doors.
The simplest form of solar water heater (a tank placed in the sunlight) is augmented
by a simple reflector as shown. The bright foil-clad reflector held by an aluminum
frame lights the back of the tank when positioned properly each month.
