D-60 Study on Simple Evaluation Method of Seasonal Load including Outdoor Air Load : Part2. Evaluation Method of Heat Load of Natural Ventilation considering the Air Flow of a Top and Bottom Floor Direction

Abstract

The purpose of this study is to establish a simple evaluation method of building seasonal load when the building is designed to in take outdoor air intentionally. For simplification of the method, an expression to estimate pressure difference was made, and the number of parameters which were related to natural ventilation was reduced. Using these results, it was showed how to evaluate seasonal heat load of natural ventilation.
