Evaluation of passive-solar modular dwelling, June 30, 1980-August 30, 1981. Final report
One of the designs approved in the TVA Modular Solar Homes Project was installed, instrumented, and evaluated at Tennessee Energy Conservation in Housing Center on the University of Tennessee campus. This house was the 111m/sup 2/ Bayside model from Dixie Royal Homes. Its major passive feature is twenty cylindrical water tubes behind 14.6m/sup 2/ of south facing bay windows. The windows were insulated at night with an R 2.8 insulation curtains. Infiltration measurements were made and summer temperatures were monitored. A computer simulation was developed and the water tube portion was verified by comparing its predictions with data collected from the house and water tubes over a three week period. This verification showed the tube model water temperature predictions to be within three percent of the measured data. Some parts of the simulation program were used to calculate the net solar gain through the south glazing using measured weather and temperature data for the 1981-1982 heating season. With the measured auxiliary energy and the calculated net solar gain, a solar fraction of 0.40 was determined for the heating season. Using heating season data from a Knoxville TMY, the performance of the system and several alternatives were simulated by the complete simulation program. The alternative buildings were oriented in the same direction as the passive solar modular house (due South). The house, as designed, required 10 percent less auxiliary energy than the same house without water tubes, and 46 percent less energy than the same house with conventional amounts of south glass and no tubes or night insulation.
