easibility Analysis of Green Technologies For Residential Buildings

Abstract

Pakistan is suffering from acute energy crisis since last decades. There is a big gap between power supply and demand and the shortfall is about 5000 MW per day. This shortfall is badly affecting all sectors which consumes electricity like residential, commercial, industrial and agriculture etc. Among the total energy about 43 % is consumed by the residential buildings. This high consumption needs to be minimized so finding desirable and effective ways to minimize the energy consumption of existing residential buildings and to propose strategies that are energy efficient is the aim of this research work. Each household has its own energy consumption pattern which is affected by the socio-economic conditions, number of occupants, the age group and gender. Thus, figuring out a generalized procedure for the transformation of residential buildings into the energy efficient building becomes very challenging. The proposed methodology aims at optimizing the energy consumption of residential buildings and finding a generalized procedure that can be adopted to transform any residential building into a low energy building. The test site selected for the proposed work is situated at canal town Peshawar which is a residential building. To lower down the electricity consumption of the selected building different insulation materials and energy efficient equipment’s along with different retrofitting strategies are analyzed in this research work. The financial analysis is also carried out based on the KWH savings, with an improvement in energy consumption up to 30%. Keywords— LEB, Retrofitting, Energy Efficiency, Green technologies.
