The 2002 Solar
House was S&T's first entry into the Solar Decathlon. It was built by
S&T and RIT students and was eventually permanently placed at the Solar
Village. The house has a simple layout being described as a typical midwest
ranch. The roof is covered with photo-voltaic cells as well as water heating
tubes. Inside are several energy efficient appliances as well.
The house
makes power from 32 BP Solar BP-3160 Solar pannels producing 5.12kW. These
panels charge 8 Trojan L-16H lead acid batteries which hold 375 Amp Hours of
charge at 48 Volts. The batteries run through 2 Trace SW5548 inverters changing
the 48V DC into common 110-120VAC current found in almost all homes. The
house's hot water comes from 40 Thermomax evacuated tubes which heat water that
is stored in an 80 gallon storage tank. The house is heated and cooled by a
Mitsubishi heat pump. A resistance heated forced air system provides added heat
on extremely cold days.
Standard stick
and timber construction was used on the 02' house. Walls were constructed out
of steel studs and filled with extruded foam. Originally the roof was designed
to fold and the house was built into three sections to make transportation to
Washington, DC easier; however, the house is now permanantly fastened together
and to the foundation.
The house
uses nothing but energy efficient appliances. The washer/dryer combination unit
is much more efficient than if the house were to have a separate washer and
dryer. Energy efficient floresent lighting lights the house with the bulbs
using 75% less power than conventional lighting. Appliances are hidden behind
cabinet faces to give the kitchen a more uniform look. Also, the living room
bookcase is built into a door so that the bedroom and living room can be
connected in order to give the impression of a larger room.
