A novel method is described for room heating using stored solar heat. Solar heat is stored in an insulated tank by using scrap and inexpensive heat absorbing or heat storing materials. Stored heat can then be extracted by air circulation for room heating. The temperature of the room air is controlled by a thermostat. When the room temperature drops below the set point on the thermostat, a circulating air pump turns on and extract the solar heat until the room temperature air reaches the desired set temperature. Once room temperature reaches the set point in the thermostat, the air circulation pump turns off.

The system and method to maintain the temperature inside a building or house within comfort levels independently of the Grid. The system has a collector; an accumulator; and a transformer, which is the building or house. The method consists of transforming energy from solar radiation into thermal energy, accumulating that energy into an accumulator, and using that accumulated thermal energy to warm the internal environment of buildings or houses. One of its loops functions between dawn and sunset and includes only the collector and the accumulator; its second loop includes only the accumulator and the transformer and operates primarily between sunset and dawn. The collector uses a blackened surface to transform sun's radiation into thermal energy to warm air that is used to conduct the thermal energy throughout the system. The system can be built with inexpensive material; utilized in significantly isolated areas; and constructed and assembled on site.

A greenhouse, for cold weather climates, is configured with a gable that is offset toward the north wall and therefore the south extension of the roof, from the gable to the south wall is longer than the north extension. A greater amount of light can enter through this south extension and the inside surface of the north wall is configured with a reflective surface to allow light to be more uniformly distributed around the plants. The north wall may have no widows and may be thermally insulated to prevent the greenhouse from getting too cold during the night. A ground to air heat transfer (GAHT) system may be configured to produce a flow of greenhouse air under the greenhouse for heat transfer, to moderate the temperature of the greenhouse. A thermal medium may flow to a thermal reservoir for heat exchange with the conduits of the GAHT system.
