Advanced Innovative Solutions for Final Design in Terms of Energy Sustainability of Nearly/Net Zero Energy Buildings (nZEB)

In this Reprint, we gather innovative research on advanced strategies to enhance building energy sustainability and accelerate the transition toward nearly and completely net-zero-energy buildings. The articles combine experimental studies and numerical modeling to identify effective solutions for reducing energy use, limiting greenhouse gas emissions, and improving indoor comfort in various climates. The contributions cover a broad range of technologies applied to both the building envelope and systems, including passive solutions such as phase-change materials, green roofs, dynamic insulation, high-performance walls, flexible canopies, and prefabricated straw bale construction. Window innovations are explored through studies on electrochromic glazing and ventilated double-skin façades. Several papers also assess energy performance standards and thermal comfort regulations, offering insights into certification processes and policy frameworks. Additional works expand the focus to novel air-conditioning concepts, visual comfort optimization, and smart monitoring tools for zero-energy building management. By merging diverse perspectives and methodologies, in this Reprint, we provide a concise yet comprehensive overview of emerging trends in sustainable building design, offering a reference for researchers, practitioners, and policymakers committed to improving building efficiency and climate-responsive architecture.
