Development of a Building Energy Performance Index for Hot-Humid Regions

Abstract

INDEX is the nationally accepted benchmark in processing and evaluating energy usage in architecture. It has been measured and analysed from the four main impact factors of buildings; site and location, building form, construction materials, and the mechanical efficiency of the equipment inside the buildings. These also attempts to figure out a case study which can be classified according to three characteristics; old building, typical building and the energy efficiency of the building. Main objective of the case study is to find out the mean score of each item and to use the score as benchmark. Afterwards, the relations of factors consider the weighting evaluation, analysed on a similar basis. The consumption coefficient is used to make an index which has been scored into relationship formulation. The total numbers of scores which are based on the four key criteria provide an indication of the energy efficiency of the building. A score of 1 point is given for the standard benchmark. Scores below 1 point indicate better building performances. The outcome of the research was a computer program and formulation. This can be used as a simple tool for layman or as an appropriate guideline for designing and renovating buildings. The research results are used to gain a clear picture of energy performance of buildings and contribute to know how to achieve and improve for better results for the design and construction of high performance green buildings, as well as introduce the basis of energy conservation code for hot humid regions and illustrate how this method can help to meet sustainability targets.
