APPLICABILITY STUDY OF PREVIOUS MODELS FOR SEPARATING THE DIFFUSE AND DIRECT COMPONENT OF GLOBAL RADIATION IN LOW LATITUDE REGION

Abstract

In recent years, in Southeast Asia and the Middle East, large scale buildings have been constructed along with economic development. On the environmental and facility design of those buildings, energy consumption prediction must be performed in detail. It is necessary to grasp the meteorological conditions in the place where the buildings are constructed. Among the meteorological data, director diffuse radiation is separated from global irradiance generally. However, separation models were developed with the data in middle or high latitude regions. Therefore, we have measured meteorological data in low latitude region, and verified the applicability of the models with the data.
