However, uncertainty remains regarding the best roofing material for improving subsurface cooling during hot summers in temperate continental arid climates. Comparative studies on different roof materials under various climatic conditions are essential to determine the most effective heat mitigation strategies for arid oasis cities. We present a conceptual model to examine the relationship between roofing materials and their thermal mitigation capabilities in arid regions during hot summers, while assessing the influence of climate factors on their cooling performance. An experiment in Urumqi evaluated the subsurface heat mitigation capabilities of four roofing materials: white polymer materials (WPM), sod (SOD), asphalt (ASP), and solar photovoltaic panels (SPP). The results showed that the WPM provided the most effective subsurface cooling. Compared with SOD, ASP, and SPP, WPM showed the lowest subsurface temperature. Notably, the subsurface temperature of the WPM was minimally affected by climatic factors and showed no correlation with solar radiation intensity, precipitation, and cloudiness (<em>P</em> &gt; 0.05), highlighting its superior cooling performance. WPM roofs are recommended for heat mitigation during hot summers in arid oasis cities owing to their low maintenance costs, ecological benefits, and superior cooling performance. This study highlights the subsurface cooling capabilities of various roofing materials and their interaction with climatic factors and provides valuable insights for heat mitigation strategies in arid regions.</div></div>","PeriodicalId":9273,"journal":{"name":"Building and Environment","volume":"267 ","pages":"Article 112282"},"PeriodicalIF":7.1,"publicationDate":"2024-11-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142661409","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}

To this end, a path model was formulated with aid of 1749 face-to-face field interview responses collected via questionnaire surveys together with physical measurements at the COS of nine residential housing estates in Hong Kong. The model findings suggested that pleasantness and landscape visual quality, as well as thermal acceptability were the primary drivers for soundscape quality of COS. The size of effects of thermal perceptions on soundscape quality was found comparable to those of aural and visual perceptions. In turn, pleasantness was more influenced by perception of dominant vehicle sound, human sound and birdsong than physical sound properties and psychoacoustics factors. Visual quality of landscape also played an important role on soundscape assessments via visibility of greenery and sky. Besides, thermal acceptability was found to directly influence soundscape assessments instead of thermal comfort or sensation. Above all, our findings provide valuable insights for residential housing estate designers in formulating strategies that can effectively improve soundscape quality in COS in compact city environments.</div></div>","PeriodicalId":9273,"journal":{"name":"Building and Environment","volume":"267 ","pages":"Article 112261"},"PeriodicalIF":7.1,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142661525","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}

The time length of the adaptation phase in existing studies disperses largely, which either risks low evaluation reliability or high time and economic costs. This study proposes to determine the time length of the adaptation phase for reliable subjective thermal environment evaluation and to avoid unnecessarily large time and economic costs. First, the variation and distribution of the initial thermal status of the adaptation phase are inferred from a steady bioheat model with ASHRAE (American Society of Heating, Refrigerating and Air-conditioning Engineers) Thermal Comfort Database II. Second, with the initial thermal status, the variation and distribution of the thermal stability time are inferred from the dynamic bioheat model. Third, the time length of the adaptation phase is quantified from the distribution of the thermal stability time according to the targeted reliability level. Results show that under the summer scenario, the time length of the adaptation phase increases from 16.9 <em>–</em> 31.2 min to 25.2 – 38.9 min when the reliability level increases from 90.0 % to 97.5 %. The time length of the adaptation phase of the winter scenario increases by 5.3 – 9.7 min relative to that of the summer scenario. A strategy of shifting the adaptation phase from thermal neutrality to slight warmth is proposed to effectively shorten the time length of the adaptation phase by 5.6 % – 19.4 % and 7.8 % – 23.9 % in the summer and winter scenarios respectively.

As one of the most promising advanced ventilation strategies, impinging jet ventilation (IJV) has received much attention. However, few study concerned its coupled indoor thermal and humidity environment and there is also no complete mathematical model for the IJV to synchronously predict its indoor temperature and humidity distributions. Therefore, this study first simulated the thermal and humidity environment in IJV rooms with considering the coupled thermal and moisture transfer effect. The results demonstrate a significant correlation between temperature and humidity distributions in IJV, with a correlation coefficient of approximately 0.4. Then, a simplified theoretical model for predicting temperature and humidity distributions in the IJV was established based on the theory of nodal model, and the key parameters within the model that are influenced by indoor airflow pattern were also identified. Next, the model results were compared with the simulation ones and showed that the proposed model is with a mean absolute error of 0.4 °C for the prediction of temperature distribution and of 0.21 g/kg for the prediction of humidity distribution. These discrepancies are sufficiently minor to validate the accuracy of the proposed model. Last, the potential application value of the proposed model was discussed. Overall, the current study contributes to extend the application of the existing coupled thermal and humidity models to IJV scenarios, and provides a robust theoretical foundation for the more rational design and practical application of the IJV.</div></div>","PeriodicalId":9273,"journal":{"name":"Building and Environment","volume":"267 ","pages":"Article 112272"},"PeriodicalIF":7.1,"publicationDate":"2024-11-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142661524","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}

Flow visualization results indicate that upstream stagnation levels significantly increase with increasing building height, along with higher wind speeds in approaching BLF, causing stronger front downwash flows and upwash flows behind higher buildings. Variation in flow structures with building height significantly change pedestrian-level wind speed fields, including (1) causing a significant increase in mean wind speed on the sides of buildings, although their influence on turbulent kinetic energies (TKE) in the region is not obvious; (2) causing an increase in mean wind speeds and especially TKE downstream of buildings; Accordingly, high peak pedestrian-level winds for higher buildings occur not only in windy regions beside buildings but also in generally considered low-speed wake regions. This suggests that measurement of only mean pedestrian-level wind around buildings, especially super high-rise buildings, may not be adequate and might underestimate the influence of pedestrian-level winds on pedestrians. In addition, by zoning according to different fluctuating wind characteristics around buildings, peak pedestrian-level wind speed can be estimated by gust factor with better accuracy.

Bay areas around the world are currently experiencing different stages of urbanization, and the transformation of urban land cover into thermal environments varies significantly. This study investigated the spatial-temporal changes of land cover change (LCC) and the land surface temperature (LST) in four major bay areas (including the San Francisco Bay Area (SFBA), the New York Bay Area (NYBA), the Tokyo Bay Area (TBA), and the Guangdong-Hong Kong-Macao Bay Area (GBA)) from 2000 to 2020. Utilizing correlation analysis and the multiscale geographical weighted regression model (MGWR), the goal was to understand how LCC impact the thermal environmental regionally. The results showed that: (1) The main shift in land cover involved a decrease in forested and cultivated area and an increase in impervious surfaces, with deforestation and agriculture conversion being major factors in this increase. The GBA gave a significant 112% rise in impervious surface during this period. (2) The LST trended towards higher, medium LST zones, closely linked with urban impervious surface expansion. (3) The MGWR model highlighted the direct non-stationary relationship between land cover alterations and LST effects. It showed that conversion to impervious surfaces, particularly from water and cultivated lands, markedly intensified LST, whereas water bodies and forests demonstrated a substantial capacity to mitigate LST. Urban planners were advised to mitigate LST elevations stemming from the transformation of forest lands and aquatic environments into impervious areas, a change notably prevalent in highly urbanized regions.
