ENERGY RETROFIT OF BUILDINGS

Abstract

More than one third of worldwide energy is consumed in buildings, accounting for about 17% of global carbon emissions. In large cities, building energy use can account for up to 80% of carbon emissions. The built environment is therefore a critical part of the climate change problem and solution. The vast majority of buildings that will be around in 20, 30 and even 50 years from now have already been built and are impacting our environment. Therefore to address climate change we must focus on reducing the energy used by existing buildings. In this regard, the dissertation has been carried out with an attempt made to study the processes of realisation of retrofitting potential and incorporating it in real world scenario. The existing literature in the field of energy retrofit has guided us to establish the loopholes in the techniques currently followed and helps us form a systematic approach towards taking the appropriate retrofitting measures. This dissertation report includes a study of various retrofitting techniques that can be followed in general, method of assessment of energy performance of a building and applying these to a case study of Lecture Hall Complex, lIT Roorkee. Manual computations of results and analysis are done on the same in lighting, electrical, plumbing and HVAC. This is further validated by E-quest energy simulation software.
