Passive Diurnal and Yearly Solar Energy Control Applied hrough Calculated Building Surface Exposure at Various Latitudes.

摘要

A study has been carried on to determine the effect of building openings and orientation vis-à-vis the needed energy to keep interior spaces within the comfort zone. For this analysis the average temperatures throughout the year and average diumal temperature swings at four different locations were applied, indicating the effect of exposure to morning direct radiation, versus noon and afternoon and the potential energy gain from optimized orientation of buildings. Data such as temperature values were assigned the anticipated average based on collected data. Depending on latitude and local climate, it was evidenced that minor angle shifts may produce noticeable results in terms of energy gain or block. It is also evidenced information on the time energy is gained is as important as information on the daily overall gain. The energy gain of applying optimized orientation produces no environmental impact and negligible if any initial financial costs.
