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

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.
