The Analysis of Tall Building Energy Performance by Using EDGE Application towards Net Zero Energy Building (NZEB)

Abstract

Net Zero Energy Building (NZEB) is one of the innovative concepts for sustainable buildings because of its ability to save energy and reduce carbon emissions simultaneously. This study used a descriptive approach to review tall building data through the parameter of saving electricity by using the EDGE application. Primary data is data obtained from working drawings or detailed engineering design (DED), work plans and specifications, and budget plans. EDGE application also produced several outputs to analyze energy performance: final energy use, operational CO2 emissions, embodied energy, utility cost, cooling loads, energy savings, operational CO2 savings, cost savings, annual EPI base case, improved EPI, number of affected people, base case and improved global warming potential of refrigerants. The EDGE also analyzed the following data: building type, site location, project details, building utility data, occupational and operational information, building dimension and specification, HVAC system, fuel used, and climate data. The energy performance of the building is analyzed by using EDGE’s parameters coded by EEM 01-37 that span from the windows-to-walls ratio to the use of low environmental impact refrigerant.
