Abstract

Evaluation of the ventilation performance of buildings, especially for residential houses, is complicated because many rooms are connected intricately and there are many factors which influence ventilation condition. The purpose of this study is to clarify the relations among ventilation performance, ventilation systems, air tightness of house and other factors, using Supply Rate Fulfillment index and network flow model. SRF index can treat transferred air, which passed through other rooms, as certain potential of fresh air. Following conclusions are obtained for the ventilation performance evaluation of different systems in an apartment house. ・Under the condition of using F_<co>-class plywood and applying ventilation requirement in the Japanese energy conservation standards (1999), the concentration of formaldehyde will be below the WHO standard. ・The range of wind velocity and wind pressure, in which Overall Supply Rate Fulfillment index complying with ventilation requirement for individual rooms in the Japanese energy conservation standards stay lager than 0.8,are shown.
