This study aims to bridge this gap by developing an AI-driven, blockchain-secured DT solution for smart building management. A multi-stage empirical methodology was adopted, combining an extensive literature review, expert consultations and iterative prototype development. The research findings indicate that according to industry experts, real-time data processing, enhanced security, predictive analytics, user-friendly design, seamless integration with other systems, and sustainability considerations are among the most critical features for effective BMS, which are reflected in the proposed framework. A functional platform prototype was designed, developed and evaluated through real-world testing in an administrative building, demonstrating improved automation, responsiveness and an intuitive user experience. This study contributes to both academia and industry by providing an integrated, scalable and empirically validated model for next-generation BMS. Going beyond theoretical exploration, it presents a practical roadmap for implementing new technologies in building operations, supporting effective integration, improved resilience and increased sustainability.

This study addresses the research gap in prioritizing LEED healthcare criteria for green hospitals in Türkiye, a topic that has received limited attention. The aim of this study is to develop a hierarchical framework using the Analytical Hierarchy Process (AHP) to rank these criteria while factoring in essential project management principles such as cost, quality, and time. The research problem was modeled using SuperDecisions software, and 10 experts provided insights through 28 pairwise comparisons, with results indicating that the “Materials and Resources” criterion is the most important, while “Innovation” is the least important. This research offers practical strategies for prioritizing LEED healthcare criteria, improving decision-making in the design and certification of green hospitals. The AHP methodology enhances transparency in the ranking process, providing valuable insights for architects, building engineers, healthcare facility managers, and policymakers. The study's originality lies in integrating project management principles with the AHP framework to address the unique challenges of designing sustainable healthcare facilities in Türkiye. By focusing on the priorities of various decision-makers, this research contributes to the efficient implementation of LEED certification, guiding the transition of existing hospitals. The study is expected to serve as a roadmap for Türkiye and other countries in obtaining LEED certification.

Ambient temperature and humidity levels play a crucial role in enhancing the efficacy of tasks performed within an occupancy area. Due to the discomfort caused by hot weather conditions in tropical regions, the use of cooling systems is common practice to help normalize the environmental temperature for the comfort of the occupants. However, inefficient air conditioner usage, especially when rooms are unoccupied, leads to excessive energy consumption and high electricity costs. To address this issue, this paper proposes an Arduino-based solar-powered smart monitoring system for occupancy and energy use in lecture rooms. The system consists of two solar-powered Arduino boards (Wemos D1 and AI-Thinker camera). The Wemos D1 integrates a temperature sensor and a PIR motion sensor to monitor environmental conditions, while the AI-Thinker camera provides image-based occupancy verification via Telegram. Real-time data transmission is enabled through Blynk and Telegram applications, allowing remote monitoring of room conditions. Results show that the system achieved 41.12 % weekly energy savings, effectively reducing carbon footprints and operational costs. The prototype conforms with SDGs climate action and clean energy initiatives, demonstrating its potential for sustainable energy management in lecture rooms.","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"28 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143678181","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Short fibers improve mechanical properties as well as reduce cracking due to autogenous and drying shrinkage of printed material. Moreover, the rheological properties of micro-reinforced composite materials play an important role to improve their processability by additive manufacturing. Therefore, the present study investigates the effect of micro-fibers addition on rheological properties and 3D printing processability of concrete based composites. For that a set a concrete mixtures containing steel, rock wool, or cellulose microfiber (varying from 0.5 wt% to 2.0 wt%) were produced. An extensive rheological assessment of the mixtures, utilizing oscillatory tests modes, like amplitude, frequency and time sweep, was conducted. The capacity to produce a continuous filament (extrudability test) and the ability to support successive layer deposition without failure (buildability test) were evaluated. The results show that incorporating fibers on concrete allows precise control of the material’s rheological properties, leading to optimize printability. The fibers addition increases the storage G’ and loss modulus G’’ of concrete, with the cellulose reinforced concrete exhibiting the highest storage G’ and loss modulus G’’. Consequently, fiber addition affects layer support and open time during printing. Among the tested materials, cellulose fibers had the most significant impact on the concrete rheological behavior. Furthermore, extrusion nozzle size should be adjusted according to fiber length to prevent clogging during extrusion. These findings contribute to better understanding the role of rheological properties in optimizing the 3D printing process of microfiber reinforced concrete.</div></div>","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"105 ","pages":"Article 112406"},"PeriodicalIF":6.7,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143698004","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, the microstructural change of GUHPC after high temperature exposure was analysed utilizing X-ray Diffraction (XRD) and Scanning Electron Microscope (SEM) methods. Test results revealed that GUHPC demonstrated different degrees of thermal damage at high temperatures ranging between 200 °C and 1000 °C but exhibited superior thermal spalling resistance. The reduction in strength, elastic modulus and fracture properties after high temperature exposure can be divided into three stages, i.e., 25–200 °C, 400–600 °C and 800–1000 °C, respectively. These three stages defined the mild, moderate, and severe damage. Compared to air cooling, water cooling caused thermal shock to specimens, resulting in a greater loss of strength.

Moreover, a support tool and roadmap are presented to integrate BIS-Model into each phase of smart building software development. The BIS-Model framework was empirically validated through a study using a real-world smart building system.
