Energy House Peeking over the horizon just on the other side of Riverknoli a new structure made its appearence this year at R.I.T. Began as a research project by Dr Paul Wojciechowski the idea of utilizing the sun's energy in a private home was realized through the joint effort of R I.T, Rochester Gas Electric and the Rochester Home Builders Association. This New England salt box” design employs some of the latest and most accessible solar technology, producing a practical phototype for a contemporary family dwelling Thirty-eight solar collectors mounted or a traditional steeply pitched roof transfer the sun’s rays into heat. Heated water from the collectors is then pumped to special holding tanks and used for the hot water system and actual heating of the house. This system, in conjunction with fortified insulation and carefully thought-out window placement results in a nearly self-sufficient energy system. Electricity is used for traditional lighting and appliances as well as heating the water In the holding tanks up to temperature during extended periods of poor weather. 4

Air Flow Air is heated by the sun which enters through the front bay of windows. Due to the open design the heated air rises through the first and second floors. As this air reaches the apex it cools and drops down the shaft created by the steel staircase. A louver door at the basement level of the staircase adds additional drawing power for the cooling air. Once entering the basement the air is drawn into a vent where residual heat is extracted for re-circulation and spent air is exhausted outdoors. Water Flow There are four holding tanks. As hot water in the first hot water tank cools (approx. 2 degrees a day) It is pumped into the warm tank This process is repeated with each tank — warm into cool, cool into cold, and provides for maximum heat retention, Water from the cold tank isthen pumped up to the roof, heated by the solar panels and then returned to the hot tank, thus completing the cycle.
