However, the inherently large thermal mass of TABSs, which results in slow thermal responses, may pose a risk of surface condensation under these conditions. In this study, to ensure TABS operation while preventing surface condensation, a computational fluid dynamics (CFD) model was developed that reproduces an entire floor of a building and the TABS. Through unsteady CFD analysis, the moisture generation sources in the indoor environment were evaluated, and a dew point temperature prediction formula was constructed based on the indoor moisture balance. Next, the surface temperature fluctuations caused by the moisture absorption and desorption of concrete were addressed, as well as the problem of uneven surface temperatures arising from the architectural structure. A safety rate was added to the predicted dew point temperature to mitigate the risk of condensation further. For the control method that keeps the entire TABS surface condensation-free, a model predictive control (MPC)-based control method was used to minimize energy consumption. The effectiveness of the proposed control method was validated through coupled analysis using MATLAB and CFD. The results demonstrated that the proposed MPC-based condensation-free TABS operation method could reduce energy consumption by 12.4 % compared with on/off control and by 9.3 % compared with standard MPC while keeping the entire surface condensation-free. Additionally, the indoor temperature was maintained at approximately 24 °C, providing a comfortable indoor thermal environment.</div></div>","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"114 ","pages":"Article 114245"},"PeriodicalIF":7.4,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145254806","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}

This study introduces an excellent approach to modify the cement-based repair materials through in-situ polymerization. The results demonstrate that in-situ polymerization substantially enhances the toughness and interfacial bonding strength of the repair materials. Specifically, compared to the control group, the flexural strength and tensile bonding strength of the modified group (with 5 % monomer content) increase by 57.6 % and 103.2 % at 28 days, respectively, while the compressive strength remains unaffected. Furthermore, the paper explores the mechanisms underlying the enhanced interface bonding strength, emphasizing the interlocking of the toughened repair material with the old substrate and the pinning effect of the penetrating monomers within the repair material at the interface. Overall, this research introduces a novel strategy for improving the properties of cement-based repair materials, with promising potential for future applications.","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"15 1","pages":""},"PeriodicalIF":6.4,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145254777","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}

Foam concrete is the focus of researchers as an alternative to traditional concrete due to its low density, high thermal insulation, lightness and environmentally friendly advantages. However, studies on the resistance performance of aluminum-added foam concrete against both high temperature and acid attack are limited, and there is a significant gap in the literature in this area. This study investigates the effect of using granulated blast furnace slag (GBFS) and fly ash (FA) in different proportions instead of cement on the performance of foam concrete containing fixed proportions of aluminum and foam. Fresh properties (flowability), physical properties (fresh unit weight, apparent porosity, water absorption and oven dry density), mechanical properties (7, 28, 90-day compressive strength and 7, 28, 90-day flexural strength), transport properties, and thermal conductivity parameters of foam concrete were investigated. Moreover, the performance against high temperature exposure and acid attack, as well as the effect of cooling methods (air and water) after high temperature on the performance of foam concrete, were investigated. In case of cooling with water, the compressive strength of samples exposed to high temperatures of 300, 600, and 900 °C decreased by up to 40 %. Samples containing FA preserved both early age and compressive strength more effectively after 600 °C temperature. Although GBFS was effective on early age strength, it deteriorated more at high temperatures.

But dynamic boundary conditions like solar radiation, wind, and atmospheric factors cause spatiotemporal thermal non-uniformity, deviating from the uniformity assumption. Thus, non-uniform thermal behavior of the National Stadium was studied by long-term monitoring and numerical analysis. Sensor node was developed with vibrating-wire stress/temperature sensor and wireless communication module comprising ATmega64, CC1101, TPS7333, AT45DB641E, and ADS1115. A robust tree-type wireless sensor network was deployed, featuring time-aligned data acquisition and cloud computing-based remote platform. The National Stadium's system adopts 160 sensors to monitor temperature and stress in 40 members, including 9 top chords, 22 bottom chords, 6 webs, and 3 columns. Long-term monitoring revealed significant spatiotemporal non-uniformity in the structural temperature field, with solar radiation causing &gt;10 °C differences and daytime temperatures well above ambient. The structure showed marked thermal-sensitivity, with clear stress gradients, strong stress-temperature correlation, and annual stress variations of many members exceeding 20 MPa. Based on ray-tracing and computer graphics, an algorithm was established to identify dynamic shading effects among structural members and applied to thermal/structural analysis. A numerical method was developed that incorporates heat conduction, convection, and radiation, while accounting for realistic thermal boundary conditions induced by solar radiation, wind, and ambient temperature. In the simulation, temperature distribution was modeled using link elements, and thermal stresses were modeled using beam elements. Measured and simulated data closely replicate each other, with average error rates for temperature and stress in monitored members below 8 % and 16 %, respectively, and average deviations within 2.9 °C and 1.1 MPa. These results highlight the reliability of the numerical approach and support the validity of the simulation method in representing structural thermal behavior.

This study proposes an innovative dual-path optimization strategy for Phase Change Material–Cementitious Envelope (PCM-CE) systems by integrating spherical phase change macro-capsules (SPCMs) with extruded polystyrene (XPS) thermal insulation. A validated three-dimensional transient simulation model, incorporating a dynamically adjusted effective thermal conductivity to capture natural convection, was used to assess the effects of insulation placement and SPCM content under realistic sol–air boundary conditions. Results show that the external-insulation (ETIM) configuration enables pronounced synergy between thermal resistance and latent heat capacity: increasing SPCM content from 0 % to 20 % reduces temperature amplitude by 63.1 %, increases time lag by 72.2 %, and decreases heat flux amplitude by 70.0 %. In contrast, the internal-insulation (ITIM) configuration achieves less than one-third of these improvements due to phase-change activation mismatch. An optimal combination of 15 % SPCM and 10 mm XPS delivers comparable regulation to 20 % SPCM while reducing material use and cost. Energy storage analysis confirms that insulation placement exerts a greater influence on dynamic regulation than total storage capacity. The proposed framework—ETIM enabling full-cycle PCM activation, complemented by optimized SPCM content—offers a scalable, engineering-feasible solution for climate-adaptive retrofitting and high-performance new construction in high-diurnal-range regions.</div></div>","PeriodicalId":15064,"journal":{"name":"Journal of building engineering","volume":"114 ","pages":"Article 114238"},"PeriodicalIF":7.4,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145222990","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}

The ashes were characterized by X-ray fluorescence, X-ray diffraction, thermogravimetry, particle size distribution, real specific mass, and determination of amorphous and crystalline silica. Pozzolanicity was assessed in calcium hydroxide pastes and suspensions, by thermogravimetry and electrical conductivity. In cement–ash pastes, the Frattini method and scanning electron microscopy were also performed.

Using computer-generated 3D office images created through parametric modeling, we developed a database of 1024 labeled scenes. Our digital equivalent of a controlled experiment included carefully designed “control” and “test” conditions, indicating the presence or absence of each attribute, such as window size and operability, visible sunlight and view features, types of furniture, indoor plants, and natural materials. Using a multi-image ranking survey, we crowdsourced 24,888 rankings from 2100 participants and derived a novel perception score for each image (a Q<ce:inf loc=\"post\">M</ce:inf>-score). We trained machine learning models (SVMs) to predict scores based on single and combined attributes. Larger windows and visible sunlight predicted higher scores across all perceptions. Window view depth was a stronger predictor of high scores than natural views. Wood floors emerged as a strong predictor of increased productivity and comfort. Multi-attribute models with combined terms outperformed single-attribute models, and the connection model achieved the highest prediction accuracy (68.8 %).

A simulation-based methodology was implemented using TRNSYS 18 for a case study office in Bolzano, Italy. The control framework employs a “controller and worker” configuration, where the controller represents the building and the workers simulate potential control actions. These actions are evaluated using a cost function that integrates key performance indicators (KPIs): total energy consumption, thermal comfort under direct solar exposure, and visual contact with the exterior. Three control modes were defined by adjusting cost function weights to prioritize energy savings, view quality, or thermal comfort.
