Abstract
t— Building energy demand increases gradually as the urbanization advances. Energy consumption due to space cooling is a crucial area of research. Researchers around the globe, attempt to replicate the energy behaviour of building using numerous types of simulation tools. In this study, a model of an engineering college has been considered for analysis of energy consumption throughout a year. This article explores various factors affecting overall energy demand of a building which is located in the hot and dry climate of Bikaner (28.0229 °N, 73.3119 °E), India. An air-cooled chiller is modelled in eQuest, which is a building modelling and simulation tool, to meet the space cooling requirement of the building and a baseline model in eQuest is created in compliance with ASHRAE 90.1 and Energy Conservation Building Code (ECBC), Government of India. The impact of different building orientations and construction of roof assemblies on energy utilization is investigated. A lucid impact of aforementioned parameters on building energy requirement is observed which turns into a considerable saving in annual energy consumption up to 3.36%.
