There is growing concern about the health effects of school classroom environments, where children spend long periods of time. However, little is known about the impact of multiple design features on children. This study used a virtual reality experimental approach to investigate the effects of classroom design characteristics on children's physiological and psychological outcomes. Ninety-six school-aged children (aged 10–14 years) experienced classroom environments using virtual reality technology and the restorative effects of seven design characteristics in different combinations were tested. The children's stress, attention, mood, and restoration were measured using physiological indicators and questionnaires during and after the experience. The results showed that six design characteristics had a significant effect on children: indoor plants, window views, seating arrangements, window areas, wall decorations, and wall and furniture colors. The effects and strengths of the different design characteristics varied. However, spatial density did not appear to have any effect. The results also revealed significant differences in cognitive and emotional perceptions according to gender and age. The need for future longitudinal experiments with long-term, real-life scenarios is discussed. The research findings can inform evidence-based design, guidelines, and standards for healthy school environments.

学校教室环境是儿童长时间待的地方，其对健康的影响日益受到关注。然而，人们对多种设计特征对儿童的影响知之甚少。本研究采用虚拟现实实验方法，调查教室设计特点对儿童生理和心理结果的影响。96 名学龄儿童（10-14 岁）利用虚拟现实技术体验了教室环境，并测试了不同组合的七种设计特征的恢复效果。在体验过程中和体验结束后，使用生理指标和问卷对儿童的压力、注意力、情绪和恢复能力进行了测量。结果显示，六种设计特征对儿童有显著影响：室内植物、窗外景色、座位安排、窗户区域、墙面装饰、墙面和家具颜色。不同设计特点的效果和强度各不相同。然而，空间密度似乎没有任何影响。研究结果还显示，不同性别和年龄的人在认知和情感方面的感知也存在明显差异。研究还讨论了未来进行长期、真实场景纵向实验的必要性。研究结果可以为健康学校环境的循证设计、指导原则和标准提供参考。

Thermal inactivation technology is an effective and safe method to control indoor bioaerosols. A predictive mathematical model describing the effect of residence time and exposure temperature on the thermal inactivation process of Klebsiella pneumoniae (K. pneumoniae), Escherichia coli (E. coli) and Staphylococcus aureus (S. aureus) in aerosol was developed. A continuous flow experimental system was set up to determine the survival ratio of bioaerosols under the wall temperature of 45–120 °C and residence time of 1.5–12 s. The experimental results showed that the thermal stability in the order from high to low was S. aureus > K. pneumoniae > E. coli. The inactivation model was developed based on the first-order kinetic model and Arrhenius equation and the model parameters were identified through particle swarm optimization (PSO) algorithm with the input of time-dependent exposure temperature calculated by computational fluid dynamics (CFD). The survival ratio calculated by the present model corresponded well with that observed in the experiment, with root mean square error (RMSE) being 0.0445, 0.0433 and 0.0376 for K. pneumoniae, E. coli and S. aureus, respectively. Based on the heat and mass transfer model for Trombe wall, it was found that solar-driven thermal inactivation could reduce the indoor bacterial concentration by up to 57 % for E. coli with thermal efficiency being 0.424 under solar irradiance of 496 W/m² and ambient temperature of 12.8 °C. In this way, solar driven thermal inactivation is a promising and sustainable method to deal with indoor bioaerosols.

热灭活技术是控制室内生物气溶胶的一种有效而安全的方法。研究建立了一个预测性数学模型，描述了停留时间和暴露温度对气溶胶中肺炎克雷伯氏菌（K. pneumoniae）、大肠杆菌（E. coli）和金黄色葡萄球菌（S. aureus）热灭活过程的影响。实验结果表明，生物气溶胶的热稳定性从高到低依次为金黄色葡萄球菌、肺炎双球菌和大肠杆菌。灭活模型是基于一阶动力学模型和阿伦尼乌斯方程建立的，并通过粒子群优化（PSO）算法确定了模型参数，同时输入了计算流体动力学（CFD）计算的随时间变化的暴露温度。本模型计算出的存活率与实验中观察到的存活率非常吻合，肺炎双球菌、大肠杆菌和金黄色葡萄球菌的均方根误差（RMSE）分别为 0.0445、0.0433 和 0.0376。根据 Trombe 墙的传热和传质模型，研究发现，在太阳辐照度为 496 W/m2 和环境温度为 12.8 °C 的条件下，太阳能驱动的热灭活能使室内大肠杆菌的细菌浓度降低达 57%，热效率为 0.424。因此，太阳能驱动的热灭活是处理室内生物气溶胶的一种有前途的可持续方法。

Understanding personalized thermal comfort is critical for creating comfortable indoor environments and achieving energy efficiency. Thermal history has a significant impact on human thermal adaptation, but it has received insufficient attention. Combining field investigation and statistical analysis, this study introduces the thermal neutral rate (TNR) and thermal comfort and acceptability rate (TCAR) to analyze the differences in thermal and humidity responses and adaptability among groups with different thermal histories in northern China. Results show that as subjects acclimatize to indoor environments, their thermal neutral temperature rises, and humid sensation votes approach 'neutral' conditions. Participants with no prior northern thermal history require up to 1 year to adapt to district heating environments, while adaptation to humid environments may take 2–3 years. The thermal neutral temperature of the un-adapted subjects was 18.0 °C, and post-adaptation, it varied within the range of 20.2–21.4 °C. For engineers designing indoor environments, maintaining temperatures within the range of 19.1–22.3 °C meets the comfort and acceptability requirements of participants with different thermal histories in the office. These findings provide evidence for understanding human thermal adaptation mechanisms and give recommended heating temperature ranges for comfortable indoor environments in office buildings in the severe cold zone.

了解个性化的热舒适对于创造舒适的室内环境和实现能源效率至关重要。热历史对人类热适应具有重要的影响，但目前尚未引起足够的重视。本研究采用实地调查和统计分析相结合的方法，引入热中性率（TNR）和热舒适可接受率（TCAR），分析了中国北方不同热史人群的热湿响应和适应性差异。结果表明，随着受试者适应室内环境，他们的热中性温度升高，潮湿感觉投票接近“中性”状态。没有北方热历史的参与者需要长达1年的时间来适应区域供热环境，而适应潮湿环境可能需要2-3年。未适应者的热中性温度为18.0℃，适应后的热中性温度在20.2 ~ 21.4℃之间变化。对于设计室内环境的工程师来说，将室内温度控制在19.1 ~ 22.3℃范围内，可以满足办公室不同热史参与者的舒适度和可接受性要求。这些研究结果为理解人体热适应机制提供了依据，并为高寒地区办公建筑的舒适室内环境提供了推荐的加热温度范围。

Contamination control in cleanrooms is essential for maintaining high productivity across various industries. In semiconductor manufacturing environments, hazardous gas leaks from instruments can pose serious health risks to operators, especially during the preventive maintenance. In this study, the numerical simulations were performed to evaluate and optimize the fan filter unit (FFU) arrangement in a cleanroom, aiming to effectively manage hazardous hydrogen chloride (HCl) gas leakage during semiconductor instrument maintenance. To reflect the actual situation, the study incorporates leakage conditions from a reference, considering various thermal factors. The simulation results indicate that the FFU arrangement and coverage rate, which influence internal airflow under a fixed air change rate (ACH), are critical for hazardous leakage control during preventive maintenance. A quantitative and comprehensive analysis of the accumulation of leaked gas on the operator and instrument surfaces showed that the analysis score proposed in this research on the horizontal FFU array with 30% coverage was 0.44, which is minimum among different cases, indicating the best performance on controlling dispersion behaviour of the hazardous gas in the cleanroom during the preventive maintenance.

Big environmental difference between the artificial indoor environments and the outdoor environments affects human comfort and physiological responses. This study examines the dynamic changes in human psychological and thermal responses to sudden, large temperature differences under three indoor conditions: slightly warm, neutral, and slightly cold. The similarities and differences between field studies and existing laboratory research were also analyzed.

The results indicated that the indoor-outdoor temperature differences under slightly cold, neutral, and slightly warm conditions were 24.5 °C, 32.6 °C, and 39 °C. Environmental differences between indoor and outdoor conditions were influenced by various factors, including temperature, air speed and so on. Human thermal responses differed significantly among the three conditions (P < 0.01). Thermal sensation vote (TSV), thermal comfort vote (TCV), and skin temperature showed great changes after the environmental shift. Skin temperature fluctuated more during down-step, while heart rate and heart rate variability (HRV) exhibited greater changes during up-step in this test. In real-world scenarios, human thermal responses were influenced by temperature, air speed, and human behavior, resulting in deviations from laboratory findings. Furthermore, a time-dependent model for skin temperature and TSV was developed, revealing that thermal sensation changes more rapidly than skin temperature during abrupt shifts from cold to near-neutral environments.

人工室内环境与室外环境的巨大环境差异影响着人体的舒适性和生理反应。本研究考察了在三种室内条件下：微暖、中性和微冷，人体心理和热反应对突然、大温差的动态变化。并分析了现场研究与现有实验室研究的异同。结果表明，微冷、中性和微暖条件下的室内外温差分别为24.5°C、32.6°C和39°C。室内外环境差异受多种因素影响，包括温度、风速等。人体热反应在三种情况下存在显著差异(P <；0.01)。热感觉投票（TSV）、热舒适投票（TCV）和皮肤温度在环境转换后变化较大。在降压过程中皮肤温度波动较大，而心率和心率变异性（HRV）在升压过程中变化较大。在现实世界中，人类的热反应受到温度、空气速度和人类行为的影响，导致与实验室研究结果的偏差。此外，建立了皮肤温度和TSV的时间依赖模型，揭示了在从寒冷环境到近中性环境的突然转变中，热感觉的变化比皮肤温度的变化更快。

Younger schoolchildren in particular are at risk of overheating in school due to two key factors. Firstly, children have a preference for lower temperatures than adults, and yet schools are designed and operated using adult thermal preference guidance. Secondly, younger schoolchildren often lack the confidence to change their behaviour in a school setting (remove a jumper, more away from direct sunlight, drink more water etc.) without prompting from the teacher. This paper reports a pilot study of a storytelling approach to enable schoolchildren to enhance their behaviour to improve their thermal comfort. A control: intervention study was undertaken across eight classes, in two schools in Hampshire, UK, with KS1 (national curriculum Key Stage 1, age 6–7) and KS2 (Key Stage 2 age 7–9) children. A new story, “The Hottest Day at School” was developed, where actions to improve thermal comfort were introduced, read by the teacher to children of intervention classes prior to a heatwave. The thermally influenced actions and feelings of schoolchildren were assessed during the heatwave event via a sticker log activity which each child completed. Fisher's exact and Pearson's chi-squared tests indicate statistically significant differences in the actions of KS1 children in particular. Whilst acknowledging the preliminary nature of the findings, the paper suggests that the storytelling approach does enable children to adapt their behaviour to enhance thermal comfort.

由于两个关键因素，年幼的学童尤其有在学校过热的危险。首先，儿童比成人更喜欢较低的温度，而学校的设计和运营是在成人热偏好指导下进行的。其次，年幼的学生往往缺乏自信，在没有老师的督促下改变自己在学校的行为（脱掉套头衫，远离阳光直射，多喝水等）。本文报告了一项关于讲故事方法的试点研究，该方法使学童能够增强他们的行为，以改善他们的热舒适。对照：干预研究在英国汉普郡的两所学校的八个班级进行，其中有KS1（国家课程关键阶段1,6-7岁）和KS2（关键阶段2,7-9岁）的孩子。一个新的故事，“学校最热的一天”，其中介绍了改善热舒适的措施，由老师在热浪到来之前为干预班的孩子们朗读。在热浪事件期间，通过每个孩子完成的贴纸日志活动来评估学童的热影响行为和感受。Fisher的精确检验和Pearson的卡方检验表明，特别是KS1儿童的行为有统计学上的显著差异。虽然承认研究结果的初步性质，但该论文表明，讲故事的方法确实能使孩子们适应他们的行为，以增强热舒适。

This study investigates the performance of integrated personal exhaust ventilation and physical barriers in mitigating airborne transmission, addressing the critical need for effective infection control in indoor environments. Using computational fluid dynamics, we modeled aerosol dispersion in a test room and validated these results with experimental data. Experimental validation strengthened the computational findings by providing empirical evidence for system efficacy under varying airflow conditions. We examined various prevention levels, including no prevention measures, only physical barriers, and physical barriers integrated with personal exhaust ventilation. The designed system with a barrier height of 65 cm and a personal exhaust flow rate of 9 L/s per person demonstrated strong efficacy in mitigating airborne transmission. Further numerical analysis was conducted to evaluate the impact of critical parameters, including barrier height and exhaust flow rate, on the aerosol removal efficiency of the integrated system. Results indicate that reducing the barrier height to 45 cm and the exhaust flow rate to 6 L/s per person retains 95% of aerosol removal efficiency, offering the most cost-effective and sustainable design without compromising system's performance in limiting airborne transmission. These findings suggest that moderate adjustments can enhance system sustainability by enabling significant material and energy savings.

本研究调查了综合个人排气通风和物理屏障在减少空气传播方面的性能，以满足在室内环境中有效控制感染的关键需求。我们利用计算流体动力学模拟了测试室内的气溶胶扩散情况，并用实验数据验证了这些结果。实验验证加强了计算结果，为系统在不同气流条件下的功效提供了经验证据。我们研究了各种预防水平，包括无预防措施、仅有物理屏障以及物理屏障与个人排气通风相结合。所设计的系统屏障高度为 65 厘米，每人排气流速为 9 升/秒，在减少空气传播方面表现出很强的功效。还进行了进一步的数值分析，以评估屏障高度和排气流速等关键参数对综合系统气溶胶去除效率的影响。结果表明，将屏障高度降低到 45 厘米，排气流速降低到每人每秒 6 升，可保持 95% 的气溶胶去除效率，是最具成本效益和可持续性的设计，同时不会影响系统在限制空气传播方面的性能。这些研究结果表明，适度的调整可以显著节省材料和能源，从而提高系统的可持续性。

In the event of a hydrogen leak, the build-up of hydrogen near the ceiling of an underground garage poses a significant safety risk. Fast and accurate estimation of hydrogen concentration distribution is crucial for risk assessment. This study proposes a novel neural network named multi-expert variational hybrid network (MEVHN) to predict the distribution of hydrogen concentration under the ceiling when the peak concentration reaches its maximum value during a leakage event. The model utilizes data from discrete sensors to make predictions. It incorporates a mixture of experts (MoE) framework to transform the sensor data into latent variables, which are then used by a variational auto-encoders (VAE) decoder to predict the hydrogen concentration distribution. Constraints are added to the loss function to improve the prediction accuracy further. The results show that the MEVHN has an inference time of 1.3 seconds, a coefficient of determination (R²) of 0.977, a mean absolute error (MAE) of 1.86E-3, and a mean squared error (MSE) of 3.15E-5. These results indicate that the model performs well in predicting the 2D hydrogen concentration distribution.

在发生氢气泄漏的情况下，地下车库天花板附近积聚的氢气构成了重大的安全风险。快速准确地估计氢气浓度分布对风险评估至关重要。本文提出了一种新的神经网络-多专家变分混合网络（MEVHN）来预测泄漏事件中峰值浓度达到最大值时天花板下氢气浓度的分布。该模型利用来自离散传感器的数据进行预测。它采用混合专家（MoE）框架将传感器数据转换为潜在变量，然后由变分自编码器（VAE）解码器使用这些变量来预测氢浓度分布。在损失函数中加入约束条件，进一步提高预测精度。结果表明，MEVHN的推理时间为1.3秒，决定系数（R²）为0.977，平均绝对误差（MAE）为1.86E-3，均方误差（MSE）为3.15E-5。结果表明，该模型能较好地预测二维氢浓度分布。

Incorporating energy-flexibility strategies into urban blocks can yield substantial benefits in terms of energy efficiency, economic viability, and carbon emission reduction. This study proposes an energy-flexibility strategy aimed at enhancing the energy and economic performance of a residential building system that integrates photovoltaics power generation, electric vehicles charging, and battery energy storage system. Simulation models were developed to comprehensively evaluate the performance of this strategy in residential blocks with different morphologies in Shenzhen, China. Simulation results indicate that the energy-flexibility strategy can reduce the average annual grid energy consumption of the block by 41.6% for multi-story buildings, 22.6% for small high-rise buildings, and 12.5% for high-rise buildings compared to the benchmark system. The average levelized cost of electricity over the entire lifecycle is 67.1%, 40.5%, and 29.7% lower than that of the benchmark system for multi-story, small high-rise, and high-rise buildings, respectively. The average peak-time grid flexibility factors for multi-story, small high-rise, and high-rise blocks reach 0.01, 0.17, and 0.35, significantly reducing the net grid power inflow during peak electricity demand periods. The total carbon emissions over the lifecycle can be reduced by 11.8% to 67.7%, with particularly notable carbon reduction benefits observed in multi-story blocks. Compared to traditional building-attached photovoltaics systems, blocks employing the energy-flexibility strategy achieve remarkable economic benefits and peak-shaving advantages, albeit at the cost of slightly higher grid power inflow and carbon emission.

Wood buildings, with their exceptional carbon sequestration capabilities, show immense potential in achieving carbon neutrality. However, the volatile organic compounds (VOCs) emitted from these structures pose significant health risks. To address this issue, this paper proposed an innovative thermal catalytic Trombe wall (TC-T-Wall), designed with architectural aesthetics in mind. Experiments were conducted on a wood building equipped with the TC-T-Wall to evaluate its thermal performance and air purification efficiency. Heat and mass transfer models were developed and validated, and the system's performance was analyzed under varying TC-T-Wall areas. Additionally, energy consumption in wood buildings with TC-T-Wall was examined in different regions. Key findings were as follows: (1) Experimental results showed that the indoor temperature of the wood building increased from 18 °C to 41 °C, and formaldehyde concentration dropped from 1.826 ppm to zero within three hours. (2) As the TC-T-Wall area increased, the formaldehyde degradation rate rose from 67% to 93%, and the total volume of clean air produced increased from 112.89 m³ to 309.88 m³. (3) Energy consumption analysis across different regions revealed that the TC-T-Wall system performed especially well in Nanjing. In January, energy consumption was reduced by 53.69%, and in July by 19.11%, with the system producing 9,212 m³ of clean air in January and 7,259 m³ in July
