ENERGY MODELLING FOR BUILDINGS

Abstract

A penny saved is a penny earned, they said. So with joules of energy! With recent exponential increases in energy pricing, the formerly neglected or underestimated concept of energy conservation has swiftly assumed great significance and potential in cutting costs and promoting economic development, especially in developing-country scenario like India. Reckless and unrestrained urbanization, with its haphazard buildings, has bulldozed over the valuable natural resources of energy, water, and ground cover, thereby greatly hampering the critical process of eco-friendly habitat development. However, it is not too late to retrace the steps. The resource crunch confronting the energy supply sector can still be alleviated by designing and developing future buildings on the sound concepts of energy efficiency and sustainability. The 21' century is witnessing Urbanization and Industrialization at a very fast rate in India. In India, the rate of increase in generation of Electrical Energy has not been sufficient enough to meet the growing demand. The gap between the demand and supply is increasing with each passing day. Therefore there is an urgent need to develop certain measures so that this gap between demand and supply is reduced. The buildings consume significant energy and hence the buildings need to be designed so that the consumption is reduced and energy is saved. The slogan also says "Energy saved is Energy generated". India's building sector is growing fast �â� � 20 million dwellings, 19 million sq m of commercial space, 13 million sq m of retail space, and 50,000 hotel rooms over the next five years.
