Abstract
Chain hotels constitute 40.09% of all hotels, with indoor room decorations typically undergoing replacement cycles every 2 to 5 years. Robotic 3D printing-enabled prefabrication offers transformative potential for sustainable construction, combining precision engineering with environmental consciousness. This study explores its application in the hospitality sector, addressing both sustainability and ergonomic data. Using AI-driven multidimensional ergonomic latent modeling, key environmental factors such as sound insulation, lighting adaptability, and air quality are evaluated for their impact on service flexibility, safety, and user experience. By aligning technological innovation, this research provides a latent model for advancing prefabricated building adaptive decoration and low-carbon hotel design. The study underscores the importance of interdisciplinary efforts to achieve global sustainability goals and redefines prefabrication technologies, especially robotic 3D printing prefabricated decoration, as catalysts for operational excellence and transformative industry standards in sustainable hospitality. Moreover, this work extends the exploration of robotic 3D printing prefabricated solutions to the context of extreme environments and even extraterrestrial buildings, such as building habitats on Mars or the Moon, contributing valuable human factors engineering insights for future adaptive built environment research in these challenging settings.

An exemption (waiver of ethics committee review) was granted by the School of Civil Engineering and Architecture, Zhejiang Sci-Tech University, on 15 January 2025 (Exemption/Reference No.: 20250115-1). The exemption was granted because the study was a non-interventional, anonymous online questionnaire on hotel interior decoration and tourists’ perceptions, collected no personally identifiable information and no sensitive personal information, and posed no more than minimal risk to participants. All procedures were conducted in accordance with the ethical principles of the Declaration of Helsinki (or equivalent standards) and applicable regulations and data-protection requirements. In line with the scope defined in China’s Measures for the Ethical Review of Life Science and Medical Research Involving Humans (issued 27 February 2023), which governs ethics review for life-science and medical research involving humans, the study was handled as exempt by the Approval Body.Footnote 1 Data handling complied with the Personal Information Protection Law (PIPL) and relevant national standards for personal information protection.Footnote 2
Informed consent
Informed consent was obtained from all participants using an implied electronic consent procedure via the Wenjuanxing platform. During the survey period (2 December 2024 to 17 December 2024), an information sheet prepared by the research team was presented on the first page of the questionnaire and described the study purpose, why the research was being conducted, voluntary participation, anonymity of responses, foreseeable risks (none beyond minimal risk), data-handling procedures, and the option to withdraw by exiting the survey at any time before submission. Consent was indicated by each adult participant (aged ≥18 years) voluntarily proceeding to complete and submit the anonymous questionnaire. Consent covered participation, use of anonymized responses for research analysis, and publication of aggregated results. The research team analyzed only anonymized responses and reported results only in an aggregated/anonymized form. We confirmed that informed consent was obtained from all subjects.
