The greenhouse-residence unit of the Sundwellings Demonstration Center at Ghost Ranch, Abiguice, New Mexico, has been studied by computer modeling and simulation techniques. A thermal network model of the building has been developed in the framework of PASOLE, the Los Alamos passive solar energy simulation program. Simulation studied based on hourly weather data recorded during the 1977--78 heating season leave been done. Model validation was done by hourly comparisons of simulation predicted temperatures in the building with measured values of corresponding temperatures. The building model was used to predict a 12-month performance with the 1976--77 Los Alamos weather data. A solar fraction, the ratio of the solar portion of the residence heat input to the total heating load, was computed to be 60%. Other performance and design questions studies with 12-month Los Alamos simulation runs include the importance of the thermocirculation vents, the effect of external insulation on the residence walls, and the effect of nighttime insulation on the greenhouse glazing.
