Abstract

The development of near-zero energy buildings has raised higher requirements for the airtightness of building envelopes, while existing detection methods still fall short in terms of accuracy, efficiency, and applicability. This study focuses on improving airtightness detection technologies, analyzing the limitations of traditional methods under complex climatic conditions, construction errors, and large-scale building inspections. Through comparative experiments and simulation analyses, optimized detection processes and sensor technologies are proposed to enhance result stability and sensitivity. Research findings demonstrate that the improved detection methods not only effectively identify envelope leakage points but also enable rapid quantitative assessments, providing reliable assurance for energy efficiency in near-zero energy buildings. This research holds significant implications for enhancing building airtightness control standards and promoting standardized green building inspections.
