Effect on CO2 Reduction of Installation of Outer Skin Surface Technologies in Houses and Office Buildings

Publisher Summary CO2 emissions from the commercial and residential sectors have greatly increased in Japan. Governmental regulations for energy saving are very effective for the industrial sector, but they are found to be rather ineffective for the commercial and residential sectors. Thus, low-cost measures for CO2 reduction are really required in these two sectors. This chapter focuses on the installation of outer skin surface technologies to buildings. These technologies, low-cost measures for CO2 reduction, are applicable to buildings that have high light-reflective and high heat-emissive paint and the low light-reflective and the low heat-emissive outer skin surface. The air-conditioning demand in the building is calculated according to the recently developed dynamic heat load simulation program, and assesses the extent of reduction in CO2 emissions brought by high light-reflective and high heat-emissive paint or low light-reflective and low heat-emissive outer skin surface.
