Abstract
Abstract: Energy consumption is an important aspect with respect to operating costs of buildings. Modern buildings are being designed considering their energy performance and carbon footprints. However, there is scope to reduce the energyconsumption and carbon footprints in existing old buildings by suitable retrofitting. A case study is discussed where in the energy audit of an academic institution in northern India revealed several opportunities where energy consumption can be reduced considerably. This paper presents the analysis to achieve about 33% reductions in energy consumption and around 178 tons reduction in carbon footprint in an institutional building, Govt. Girls College Buildings Village Palwal Kurukshetra, India. It recommends measures that can be implemented with moderate investments and payback period. Another important feature is the utilization of roof-tops of institute building to install solar PV power plants apart from retrofitting measures. Presently 7% energy requirement is being met through installed solar PV power plant on the rooftop of institute building. Afterinstalling such power plants at all the roof-tops of building about 25% of energy needs can be met by solar energy source.
