Abstract

The implementation of Net Zero Energy Buildings (NZEBs) is progressively vital for sustainable development, particularly in rapidly urbanizing regions such as Nashik, India. This study investigates how building performance simulation can support energy-efficient retrofitting of low-rise row housing to achieve net-zero or energy-positive outcomes. With Nashik experiencing significant urban growth and escalating energy demands, the research evaluates a range of retrofit strategies aimed at optimizing energy consumption and integrating renewable energy systems. Key interventions include passive design measures, high-performance insulation, energy-efficient appliances, and rooftop solar photovoltaic (PV) installations. Simulation results demonstrate that these integrated strategies can collectively reduce energy demand by approximately 47.68%, thereby enabling a transition to NZEBs. The findings highlight the potential for transforming existing housing stock into sustainable, self-sufficient units through a holistic retrofit approach. This research contributes to India’s broader objectives of achieving carbon neutrality, ensuring energy security, and promoting resilient urban development.
