A progress report is presented on a 2,700 ft{sup 2} (1,867.8 ft{sup 2} conditioned) home completed in mid-1994 in the Berkeley hills, which uses 320 ft{sup 2} of active, single-glazed roof panels, 2,000 linear feet of buried ground coils, 1,575 linear feet of tubing buried in a massive radiant floor and a 20,000 gal pool covered by a solar-bubble-blanket. The water-source heat pump was used for cooling of forced air to the house, heating from the ground coils to the radiant floor, and heating from the pool to the radiant floor. First, the passive performance of the unoccupied house was determined through three seasons, which showed maximum summertime temperatures of 78 F and minimum winter temperatures of 56 F, with no heating, cooling, or ventilation. With active heating, ventilation, solar heating, heat pump heating, the house maintained temperatures from 65 F at night, and from 68 to 74 F in daytime. The paper presents data on these various heating and cooling modes.
