Cost Benefit Analysis of Retrofitting for Existing Building as Net Zero Energy Building: A Case Study in Composite Climate Zone
In response to the sustainable development goals and climate change, this paper presents a case study of an existing institutional building located in composite climate zone at Chandigarh, India, for retrofitting it as a Net Zero Energy Building (NZEB). Its cost benefit analysis and payback period has been carried out. This analysis determines whether the benefits outweigh the cost of implementation of NZEB. The before and after energy demands of the building has been simulated on eQUEST and validated with actual energy bills. The results of energy simulation has been used to arrive at the potential energy savings. A 250 kWp onsite grid interactive solar PV system on rooftops of existing buildings is recommended to meet the energy demand of the building, after implementation of retrofitting measures. Simulation results indicated that annual reduction in energy demand by retrofitting of building envelope components is 28.82 MWh, by retrofitting electrical appliances is 191.87 MWh, and by retrofitting Heating Ventilation and Air Conditioning is 90.46 MWh. An encouraging reduction of 53.6% in annual energy demand by deploying various energy efficiency measures is projected.
