Transient thermal analysis of hollow clay tiled concrete roof for energy conservation and comfort

Study presents a new concept of laying hollow clay tiles (HCT) over RCC instead of Weathering Course (WC). Transient heat transmission across roof structures for typical Indian climatic conditions has been studied. Energy savings with HCT roof is found to be 38-63% than conventional WC roof. When air is allowed to flow through the hollow passages, air flow is found to take care of all variations in the outside climate and solar radiation, thus providing almost uniform roof bottom surface temperature.
