Energy Savings using Bioclimatic Architecture with Special Reference to Bahrain

Abstract

This paper is a theoretical application of the urban climatic values of Bahrain to the determination of Bioclimatic Design Strategies to be considered in the architectural design. The primary objective is the maximum exploitation of the natural strategies for the hygrothermic conditioning of buildings. The paper focuses the theme from the energy conservation point of view through the application of Bioclimatic Guidelines. The combined effect of Dry Bulb Temperature and Relative Humidity determine the hygrothermic human comfort, hence they are used as the main criteria for the analysis. Annual climatic values were considered to define the different seasons; hot, cold and comfort periods. The energy savings are established in a quantitative way, expressed by hours of conventional energy consumption when Bioclimatic Design Guidelines are applied on a building placed in the urban area of Bahrain. Climatic data recorded within the urban area is used for the study. The quantitative analysis is based on the comparative savings between a building designed with reference to Bioclimatic Guidelines were considered with respect to another building designed without considering those guidelines. A general conclusion from the study indicated that about 39% of energy could be saved if buildings are designed according to Bioclimatic Guidelines.
