ENERY CONSUMPTION ANALYSIS AND SIMULATION FOR ZERO ENERGY BUILDING

The growing urgency to mitigate climate change and reduce energy demand has led to the emergence of zero-energy buildings (ZEBs) as a sustainable solution in the construction industry. This study focuses on modeling and simulating energy consumption in ZEBs to evaluate their performance and optimize their design. A zeroenergy building is defined as a structure that balances its energy consumption with onsite renewable energy generation over a defined period, achieving net-zero energy usage.The increasing global demand for energy-efficient and sustainable construction practices has positioned Zero-Energy Buildings (ZEBs) as a vital component of the effort to combat climate change and reduce energy consumption. A Zero-Energy Building is designed to achieve a balance between its annual energy consumption and on-site renewable energy generation, resulting in net-zero energy usage. This study delves into the modeling and simulation of energy consumption in ZEBs, aiming to analyze their performance, optimize energy efficiency, and provide insights for practical implementation. The study emphasizes the importance of passive design strategies, such as optimal site orientation, natural ventilation, day lighting, and the use of thermal mass, in significantly reducing baseline energy demand. Active measures, including highefficiency HVAC systems, smart energy management systems, and the adoption of intelligent building automation technologies, are evaluated for their role in bridging the energy consumption gap. Furthermore, the research addresses challenges related to intermittency in renewable energy generation, peak load demands, and occupant comfort, proposing innovative solutions such as hybrid energy systems and advanced control algorithms. The simulation incorporates varying climatic conditions, occupant behavior, and energy use profiles to ensure comprehensive analysis and practical applicability. The insights gained can assist architects, engineers, and policymakers in making informed decisions to enhance energy efficiency, reduce greenhouse gas emissions, and support the transition to sustainable built environments. By addressing technical, environmental, and economic aspects, this work underscores the feasibility and necessity of Zero- Energy Buildings in shaping a resilient and energy-conscious future.
