Evaluation of building energy load of a multipurpose hall and its optimization through spectrally selective fenestration and passive design concepts

Abstract

Sports complexes and recreational centers are large and long-term investments that provide integrated facilities for training athletes and hosting social-cultural events. Due to their daily functioning, such buildings involve high energy consumption resulting in environmental impacts at both local and global scales. This article investigates the currently available methods for assessing the performance characteristics of a Multipurpose Hall using passive design techniques by modifying the building materials used for the wall envelope and fenestration design. Given that the proposed Multipurpose Hall is located near the composite climate of New Delhi, India, a study of climatic responses together with an energy evaluation of the building provides insight into the important envelope design for enhancing a building's energy efficiency. Several energy simulations were performed using DesignBuilder software to determine the annual lighting, heating, and cooling consumption for wall envelopes, window glazings, and dynamic shading techniques. Additionally, the solar gain of various fenestration designs was investigated, and the most energy-efficient building envelope was selected. The comparison of the baseline envelope with the modified envelope design revealed a notable improvement in energy performance.
