jismart2023010: A Study on The Energy-saving Potential Analysis and Visual Comfort of Highperformance Windows

Abstract

To achieve its “dual carbon” goals, China requires the building industry’s active participation. Building envelope design affects energy use level. Good envelope design saves energy and helps carbon neutrality. Windows balance lighting and heat control to improve indoor comfort and lower energy load. Innovative envelope design saves energy and looks good. Urgent for building industry to achieve China "dual carbon". Field studies in Qingdao reveal prevalent use of large glass windows in buildings, which are: (1) decorative but cause light pollution; (2) and prone to energy loss. Summer sun enters and increases air conditioning needs. Winter heat escapes rapidly and necessitates more heating. This article will improve the traditional windows based on the previous research results, and call this new envelope structure a high-performance window. The improved windows can significantly reduce building energy use while enhancing indoor visual comfort. As a vital energy-saving building component, enhanced windows directly boost buildings’ energy efficiency. This will lead to tremendous energy savings and emission reductions, facilitating China in reaching its “dual carbon” goals. It also bears great significance for constructing an ecological civilization. These surveys and analyses provide foundational data for follow-up research.
