Active systems harvest energy using mechanical means or external sources of energy to make energy useable, to cause air-movement for ventilation, and to store heat or “coolth” for future use. They also use mechanical equipment, including pumps, fans, and other equipment.
For the Learning Module, we proposed a combination of solar voltaic, composting water heating, and geothermal, in order to expand learning about alternatives, facilitate research, and demonstrate a range of available technologies. Solar voltaic panels are planned for the roof so as to produce electricity. The system envisioned is a 1 kilowatt system that would cost $7-10,000 and should be able to power the building. We combined this with a geothermal heating system that can be installed for about $2-3000, and a composting water heating system with a range of opportunities for as modest $500-1000.
