In Japan, the reduction of energy consumption for space cooling, accompanied by anthropogenic heat emission in summer, is an important issue. The aim of this research project is to evaluate total adaptation of advanced energy saving technologies applied to a building of NIES (National Institute for Environmental Studies, Japan), CCRH (Climate Change Research Hall: since April 2001: three story RC structure: 4,900m2). Especially the effect on the reduction of the impact for indoor and outdoor thermal environment is focused. These technologies are the control of solar shading and day-lighting, indoor ventilation system, several kinds of roof structure (rooftop greening, PV panels coverage, high-albedo painting). Now in CCRH, behavior of energy and air are monitored in the schedule of three years. A numerical simulation of annual cooling load of this building in case of total adaptation shows 52% reduction. The results of this study will be used to amend the current design standard of office building in hot and humid climatic zone from viewpoint of mitigation of urban thermal pollution.
