Description

In the previous study, the authors have already described the heat load simulation method considerling thermal effects of the external environment of a house. In this study, effect of housing density and housing direction in the housing area on the room temperatures and the heating and cooling loads is studied by the simulation method developed by the authors. While the heating load of the house in higher density area considerably increases in winter, the cooling load slightly decreases in summer. The simulation results showed that in case the housing density is less than 33%, the increase of the total heat load consisting of heating and cooling throughout an year is within 10% and in case the housing density is 53%, the total heat load increased by 30% comparing the house without adjacent buildings. It was found that the effects of adjacent buildings on the room thermal environment and heating and cooling loads are rather large in the housing area in the suburbs of large cities. The consideration of the adjacent buildings in the heat load simulation is necessary for the building model built in the housing area. When the effect of adjacent buildings is ignored, the space heating load may be underestimated.
