Energy-efficient building design optimization and renewable energy integration for zero-energy residential buildings using simulations

The increasing urgency to combat climate change and reduce energy consumption in the residential sector underscores the importance of zero-energy buildings. Residential buildings contribute significantly to global energy use, making it essential to explore innovative solutions for energy-efficient design and renewable energy integration. This study addresses the energy performance gap in achieving zero-energy residential buildings by optimizing design strategies and incorporating renewable energy sources. Through advanced simulation modeling, this research evaluates various building components, such as insulation, glazing, shading, HVAC systems, and photovoltaic panels, in the context of a single-family home in climate zone 5 (cool). The simulations were performed using state-of-the-art energy modeling tools, allowing for precise, location-specific analysis. The results highlight the potential for significant reductions in energy consumption when renewable energy systems are integrated, consistently narrowing the energy performance gap. This study not only provides critical insights into optimizing zero-energy residential building design but also offers a framework for policymakers, designers, and engineers to enhance energy efficiency in the built environment. The findings hold implications for future sustainable design practices, promoting the transition toward a low-carbon, energy-resilient future.
