THE EFFECT OF SEA BREEZE FOR URBAN THERMAL ENVIRONMENT

Abstract

Urban heat island problem is actualized in many cities, and tends to rise a peak of energy demand in the summer daytime. We investigate the new city concept with environmental symbiosis and energy conservation, and a new city model is analyzed from various standpoints. In this study, we remark two effective countermeasures for urban thermal environment, that is, (1) arrangement the city formation to make the most of sea breeze, (2) urban green planting and energy conservation in the city. We estimate these effects on typical summer by 3-D numerical model for heat island simulation which calculate the distribution of velocity, air temperature, and humidity. The effect of each countermeasures is evaluated from the results, and spatial differences of effects in the city is made clear.
