Energy Efficiency and Sustainability in Buildings

Abstract

The importance of energy efficient buildings has assumed great urgency in light of fast depleting energy resources, energy scarcity and increasing environmental pollution. Innovative ways to cut down energy consumption are necessary. The construction industry is one of the largest energy consuming sectors. In modern buildings significant amount of energy is consumed to keep the building environment comfortable. In developing countries like India, rising population, increasing standards of living and rapid urbanization result in an increase in building construction activities. To achieve the collective objectives of energy security and environmental protection, eco-sensitive buildings that utilize their resources judiciously, minimize their emissions and have efficient waste management systems, should be considered and designed. The available options in architectural intervention, building materials and design methodologies need to be carefully evaluated to minimize energy usage, minimize the ecological degradation that may be caused by the construction of the building and provide cost effective solutions. The aim is to achieve the desired comfort with the least input of conventional energy. Architects and designers accomplish the task through solar passive design, use of renewable energy technology systems, and/or natural building materials. While designing such buildings, not only new building stock can be targeted but also existing buildings can be retrofitted with energy efficient and eco-friendly technologies, thereby substantially reducing energy consumption. All put together is Energy Efficient Housing.
