PRELIMINARY DESIGN OF CALCULATION SYSTEM FOR THE DETERMINATION OF GLOBAL WARMING EFFECTIVENESS BY COOL CITY POLICY IN KAWASAKI CITY

Abstract

To mitigate the heat island phenomenon in Kawasaki, the reductions of housing air conditioning electricity consumption by the application of wateretentive system were detrmined By using AUSSSM tool, outdoor air temperature which is the major factor for air-condition load was set and the spatial distribution of outdoor air temperature in vertical direction was determined An urban model consists ofbuilding usage and land use data was developed using GIS. The electricity consumptions for air-conditioning in high-rise and low-rise congested housing district areas were calculated, and 8% and 6% of electricity consumption reductions, respectively, could be expected.
