However, the heating load significantly influences the dynamic environmental spatial distribution in PTLS mode, directly impacting occupant thermal comfort and energy utilization, yet quantitative analysis remains limited. Moreover, the performance adaptability of heating terminals also varies due to differences in heating mechanisms. Therefore, a comprehensive evaluation of terminal space heating alignment with occupant demand across multiple load conditions is essential for developing a clearer theoretical framework for PTLS heating. This study presented a comparative assessment of three representative terminals under varying load conditions from an occupant-centric perspective. An occupant-location-based evaluation method was employed to explore the temporal-spatial matching coefficients of indoor environment with occupant demand. Terminal heat consumption and entransy were analyzed to reflect both the heat quantity and quality dissipation for PTLS mode. Additionally, the impacts of convective and radiative features of terminals on mitigating the effects of load variations on heating performance were also examined. Results suggest that the increased heating load had a greater impact on the spatial matching coefficients of convective terminals with the heat consumption ratio rising by 38.5%, whereas it had a more pronounced increase in the heat source grade demand of radiative terminals (41.7%). The “convection first, then radiation” strategy with optimized airflow demonstrated effective potential for achieving demand-matched heating and maintaining consistent performance with load variations.</div></div>","PeriodicalId":9273,"journal":{"name":"Building and Environment","volume":"281 ","pages":"Article 113183"},"PeriodicalIF":7.1,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144123626","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using OpenStreetMap’s XML-based data, the model distinguishes between porous elements like trees and solid structures, enhancing urban flow analysis. The framework employs the lattice Boltzmann method (LBM) within the open-source software OpenLB to simulate pollution transport. Nitrogen dioxide and particulate matter concentrations are estimated based on traffic and building emissions, enabling hot-spot identification.

Results show that alternating east–west winds during this period create a dynamic pollution distribution, identifying critical residential exposure areas. This work contributes a novel DT framework that integrates real-time meteorological data, OpenStreetMap-based geometry, and high-fidelity LBM simulations for urban wind and pollution modeling. Unlike existing DTs, which focus on structural monitoring or large-scale environmental factors, this approach enables fine-grained, dynamic analyses of urban airflow and pollution dispersion.

This study experimentally and numerically investigates the evaporation and settling characteristics of oil in water (O/W) emulsion droplets formed by SSMWFs. Firstly, based on the separation characteristic of oil and water phases during the evaporation process, an evaporation model for SSMWFs droplets was developed, and the evaporation process can be divided into water evaporation and volatile oil evaporation. Next, the evaporation characteristics was analysed. It indicates that the SSMWFs droplets do not evaporate completely, but exist in a final state of equilibrium particle size, which is mainly affected by the percentage of non-volatile components and the initial particle size. The evaporation rate is mainly affected by initial particle size, relative humidity and ambient temperature, while the concentration of gaseous volatile oils in the environment has little effect on it. Increasing relative humidity of the local environment provides more available time for capturing droplet pollutants before the evaporation of volatile oil components, at 20 %, 80 %, and 95 % RH, it takes 3 s, 18 s, and 63 s for the volatile oil components to start evaporating, respectively. Finally, the settling characteristics show that the deca-micron-level SSMWFs droplets released in large quantities during machining can suspend for over 300 s, posing non-negligible inhalation exposure risks. The study provides guidance for assessing the impact of SSMWFs droplets on human health, and for designing effective contaminant control strategies.</div></div>","PeriodicalId":9273,"journal":{"name":"Building and Environment","volume":"281 ","pages":"Article 113181"},"PeriodicalIF":7.1,"publicationDate":"2025-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144107646","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Conventional IEQ assessment approaches, including stationary sensor networks and human-propelled field surveys, are limited in scalability in both spatial and temporal dimensions. To address this, researchers have developed mobile sensing platforms for more agile measuring and monitoring. However, a systematic modeling approach for reconstructing high-resolution spatiotemporal maps of IEQ variables from the sparse data collected by these mobile platforms is still lacking. This paper introduces a Gaussian Process Regression (GPR) framework designed to interpolate and process raw data from robotic mobile sensing platforms and IoT devices, thereby reconstructing spatiotemporal representations of various IEQ parameters from both short-term and long-term monitoring. The results demonstrate that for short-term spatiotemporal indoor air quality distribution reconstruction, GPR outperforms K-Nearest Neighbors (KNN), Random Forest (RF), and Support Vector Regression (SVR) when using different cross-validation strategies. In addition to a high correlation with the measurements and small normalized mean squared error, GPR models show a minimal bias in variance compared to the measured data. Secondly, when applied to long-term autoregressive modeling of an air temperature sensor network, GPR exhibits fast convergence and maintains a root-mean-square error of 0.21 °C over long-term predictions. The results suggest that GPR can capture the temporal and spatial variations in air temperature data.

Using a within-subject, counterbalanced design, 37 participants experienced each of these four rooms.

This finding underscores the benefits of having a window for reducing stress. While the stress levels in the room with an artificial window were slightly lower than those in the rooms with a wall-only and a higher ceiling height, these differences were not statistically significant. Interestingly, the room with a higher ceiling height presented varying stress levels relative to other rooms. The stress levels at higher ceiling heights were significantly higher than those in the room with a window. However, compared with a wall-only room or an artificial window room, stress levels in a room with a higher ceiling height statistically insignificantly differed and fluctuated depending on the type of stress measurement.
