OPTIMIZATION OF ENERGY USE INTENSITY IN A DESIGN-BUILD FRAMEWORK

The demand for sustainable building is increasing with minimal environmental impact, with increasing energy cost and more concern about environmental issues. In developing countries building does not provide sustainable condition, so the energy efficiency of the building is less. The objective is to analyze the criteria for energy efficiency, resulting in a series of feasible solution that can minimize the usage of energy and thereby reducing the energy demand and providing thermal comfort for the building occupant. And necessary improvement is performed in the building and the modeling is carried out for optimizing energy efficiency. Modeling is done qualitatively to ensure economical factors of building energy efficiency. By optimizing building energy use intensity, it offers sustainable savings in energy consumption. Building fabrics determine the energy use intensity in a residential building. By optimizing the building envelope the sustainable condition is obtained. Reducing energy use intensity from home will lower the energy production from fossil fuels. The building energy performance depends on the energy use intensity; the parameters which determine the energy efficiency of buildings are thermal comfort, water and energy. The simulation program guides the retrofitting of residential building, by optimizing the design-built framework the efficiency is improved in an economical way
