Reduction in building energy requirements by modern energy conservation techniques

Energy Deficiency problem can be addressed either by increasing generation or by efficient consumption of energy. Shortage of electricity generation and excessive usage of electricity power has promoted the energy conservation measures. Energy audit of building identifies flaws in load consumption; and overall energy performance profile can be improved. This case study presents the complete energy audit of a Public sector Multi-Office building located in Lahore, Pakistan. A methodical analysis has been performed and potential Energy Conservation Recommendations (ECRs) are proposed for the building. These ECRs are backed up by the financial analysis. Analysis concludes that more than 30% energy can be saved by efficient utilization and retrofitting measures only. On field collected data has been analyzed using software; DIALuxEvo 3 for lighting system, Hourly Analysis Program (HAP4.41) for heating and cooling system and Smart-Viewer for thermal imaging.
