Integrating Of Building Energy Modelling For Achieving Net Zero Energy Building In Hot Humid Climate

Abstract

The Building Sector Significantly Contributes To Energy Consumption, Particularly In Hot And Humid Regions Where Cooling And Dehumidification Demands Are High. In Rapidly Growing Cities Like Mumbai, Pune, And Nagpur, High Temperatures (30°C–38°C) And Humidity Levels (70–85%) Increase Reliance On Mechanical Cooling, Leading To Higher Energy Use. This Study Presents A Structured Workflow For Climate-responsive Building Design To Achieve Net Zero Energy Building (NZEB) Performance. A Seven-phase Methodology Is Adopted, Including Climate Analysis Using Typical Meteorological Year (TMY) Data, Baseline Model Development, And Building Energy Modelling (BEM) Using EnergyPlus And DesignBuilder. Passive And Active Strategies Are Integrated To Optimize Performance, Followed By Solar Photovoltaic System Implementation. Results Show Significant Energy Reduction, Enabling NZEB Achievement And Supporting A Climate-specific Framework Aligned With ECBC Guidelines.
