Traditional passive cooling techniques in hot arid regions have been discussed in previous research work to explore their passive-cooling abilities and strategies. This paper dwells on traditional curved-roof geometries and forms in order to create more energy efficient buildings and indoor thermal comfort environments in hot climates.
This paper presents part of a continuing research, which is aimed at exploring the relationship between the intensity of the received solar radiation on roofs and their geometrical configurations. Throughout the research, a number of investigations have been carried out on different curved-roofs forms (domes and vaults) with different curvatures (cross section ratios (CSR)) at different orientations to study their solar radiation performance. This paper illustrates some of the generated results which compare between the Hourly Total Clear Sky Irradiance Intensity I(HTCS) W/m2 on flat and vaulted-roof, which has a semicircular Vaulted-roof Cross-sections Ratio, VSCR = 1. The geographical latitude of Aswan (23.58oN) has been chosen to represent the hot dry climatic conditions of southern Egypt.
