Evaluating the Effectiveness of Energy-Efficient Design Strategies in Achieving Net Zero Energy Building through Reduced Energy Consumption

Abstract

Abstract: Net zero energy buildings (NZEBs) have emerged as a sustainable and energy-efficient solution to the challenges of climate change and rising energy costs. These buildings are designed to generate as much energy as they consume, resulting in zero net energy consumption. The paper explores the evolution of NZEBs and the latest emerging technologies that are enabling their development, including smart building automation systems, energy-efficient lighting and HVAC systems, vacuum insulation panels, Building Integrated Photovoltaic (BIPV) systems, and advanced sensors. The effectiveness of these strategies is analyzed using Autodesk insights and Revit software. The paper also discusses the comparison of Energy Use Intensity (EUI) before and after implementing energy-efficient and renewable energy techniques, which is crucial in determining their effectiveness. The proposed building achieved a significant 57.3% reduction in energy consumption after implementing various NZEB design strategies, resulting in a mean EUI value of 99.8 kWh/sq. m/year. The analysis was conducted using Autodesk Insights and Revit software, utilizing the Building Information Modeling (BIM) approach for building design. This paper concludeswitha discussion on the future of NZEBs and how they are an important step towards achieving sustainable and efficient energy use in the building sector,resultingincostsavings andreducedcarbon emissions
