This research used computer simulation techniques to test the effects of irradiance and wind reductions on the energy performance of similar base case houses in four distinct climate regions. A computer program that simulates shade cast from vegetation on buildings (SPS) was interfaced with a microcomputer-based building energy analysis program (MICROPAS) to model irradiance reductions. Performance of the relatively energy-efficient base case house was tested in Madison, Salt Lake City, Tucson, and Miami. Cooling loads were most sensitive to roof and west wall shade, and heating loads were most sensitive to south and east wall shade. Irradiance reductions can substantially increase annual heating costs in cold climates (as much as Subjects--Topical Terms:

520 $a This research used computer simulation techniques to test the effects of irradiance and wind reductions on the energy performance of similar base case houses in four distinct climate regions. A computer program that simulates shade cast from vegetation on buildings (SPS) was interfaced with a microcomputer-based building energy analysis program (MICROPAS) to model irradiance reductions. Performance of the relatively energy-efficient base case house was tested in Madison, Salt Lake City, Tucson, and Miami. Cooling loads were most sensitive to roof and west wall shade, and heating loads were most sensitive to south and east wall shade. Irradiance reductions can substantially increase annual heating costs in cold climates (as much as $1 28 or 28\% in Madison), and reduce cooling costs in hot climates (as much as \ $2 49 or 61% in Miami).
520 $a Wind speed reductions were beneficial in cold climates where air infiltration is a major heat loss pathway. A 50% wind reduction lowered annual heating costs $6 3 (11\%) in Madison. However, wind reductions increased cooling costs for the unshaded house in hot climates. In Miami, a 50\% wind reduction increased annual cooling costs \ $6 8 (15%). Landscape designs in temperate climates should attempt to reduce winter winds and allow summer breezes to cool unshaded surfaces.
520 $a Potential energy savings from optimal planting designs were estimated for each site and compared with costs for designs that were energy-consuming. The largest potential annual savings were found for energy-conserving designs in Tucson ( $2 00, 35\%) and Miami (\ $1 86, 38%) due to benefits from shade. Winter shade from the energy-consuming design increased annual heating costs $7 0 (10\%) in Madison. The need for precision planting techniques is greatest in temperate climates where irradiance reductions can have strongly positive and negative effects on space conditioning costs.
520 $a A benefit-cost analysis illustrated economic values associated with an energy-conserving design compared to an unlandscaped residence in Tucson. Benefits consisted of reduced cooling costs from shade, while costs were calculated for the initial planting, space heating, irrigation water, and pruning over a 20-year project life. Positive cash flows occurred during the first 10 years, but net present values were negative because irrigation water costs increased faster than benefits from shade during the last 10 years. The implication of these results is that energy-conserving designs may not be economical unless they also conserve water.
