Earth-sheltered buildings in hot-arid climates: Design guidelines

Publication date: Available online 12 May 2017Source: Beni-Suef University Journal of Basic and Applied SciencesAuthor(s): Heba Hassan, Daisuke SumiyoshiAbstractOne of the most effective techniques to meet the tradeoff between thermal comfort and low energy consumption in hot-arid climates is Earth sheltering.This paper reports the results of research series which aim to measure the suitability of applying the Earth sheltering technique at hot-arid climates, in Egypt as a case study.The research tested 164 experts’ responses about their attitude towards Earth-sheltered buildings and obtained their recommendations and preferences about the architectural and urban design guidelines.On the other hand, basement’s thermal performance was tested, through simulation and measurements to reach the calibration process.Moreover, measuring the balance between the thermal comfort, and energy savings through a parametric optimization analysis. The tested design variables were 25 window/wall ratio percentages, 23 orientation angles, and five cities location templates; Ismailia, Sharm-El-Shiekh, Al Minya, Marsa-Matrouh and Al Kharga.The research results present site-specific guidelines, through several topics; architectural design guidelines, site selection and urban planning guidelines, for architects and urban planners regarding the application of this technique for residential buildings.
