| Summary: | The Greenmoss Builders, Incorporated Solar Energy System is installed in a two story single-family residence in Vermont, and is designed to provide passive solar space heating and active solar domestic hot water preheating. The space heating system includes a Trombe wall with 278 square feet of window, gas-fired auxiliary units, and air distribution. The heating modes are: solar only; solar plus supplemental heat sources (gas-fired furnace and/or wood stoves) with thermal curtain open; residual (stored) solar plus supplemental sources with thermal curtain closed; and heating by furnace and/or stove only. An array of 88 square feet of flat plate collectors with water as the working fluid preheats the potable hot water supply before it is fully heated by a gas-fired water heater. Freeze protection is by drain-down. Modes of operation are collector-to-preheat, preheat-to-domestic hot water, and draindown. The instrumentation for the National Solar Data network is described. Original cost estimates for provisioning and installation of the solar system are given. (LEW) |
