PASSIVE SOLAR WITH THERMAL MASS WALL AND FLOOR 130 sq. ft. sunspace with blue stone floor; 150 sq. ft. of sloped double glazed insulated glass on the sunspace, at a 60 degree angle. 100 sq. ft. of vertical double glazed insulated glass facing south. 130 sq.ft. x 12" thick brick/concrete mass wall at rear of sunspace. The wall is heated by the sun in winter, and is shaded in the summer due to the higher solar angle. 1000 sq.ft x 6" thick concrete slab with tile floor on first floor of house. A thermostatically controlled fan moves heated air from the ‘solar hot air furnace’ (a.k.a. sunspace) into the living space on sunny days.
The sunspace also doubles as a solar clothes dryer and a greenhouse for starting vegetable transplants in the spring. But my favorite use of the sunspace comes when we hang up our hammock on a cold winter day. On a sunny 0℉ day, our 'solar furnace' will be 80℉ or more! Life is Good.
Snow needs to be removed from the glazing. This is fairly easy because of the steep angle of the glass. The glazing system has been exceptional. Installed in 1995, it has never leaked and the gaskets are still soft and pliable. “Pro-Seal” Glazing System Abundant Energy, Inc. Pine Island, NY 10969 www.abundantenergyinc.com
Environmental reasons were our main motivation to go the passive solar route, and Thomas Edison’s quote: “I'd put my money on the sun and solar energy. What a source of power!”
