Low-cost and portable volatile organic compound (VOC) sensors, such as metal oxide (MOx) sensors have been developed and implemented in many indoor environments. But there is a lack of comprehensive studies on how accurate and reliable these sensors are and how to interpret the data from such sensors. This study aims to address these gaps in knowledge and data by conducting a comprehensive evaluation of current low-cost VOC sensors. The performance and limitations of the sensors were assessed in terms of stability, sensitivity, accuracy, detection limits, and recovery time for 11 individual VOCs of indoor air quality (IAQ) concern including toluene, formaldehyde, acetone, dichloromethane, tetrachloroethylene, 1,1,1-trichloroethane, m-xylene, naphthalene, acetaldehyde, phenol, and benzene. A standard procedure was developed for investigating the sensors in a 50 L stainless steel chamber with various VOC concentration levels that are relevant to realistic indoor environmental conditions. A total of seven types of commercially available off-the-shelf sensors with different configurations of various operating temperatures and sleep cycles, were tested. Sensor’s performances were quantified and evaluated based on their sensitivity, accuracy and stability and were classified into three levels: high, medium and low performances. Results show that six sensors exhibited reliable detection capabilities for at least one of the following compounds: acetaldehyde, acetone, benzene, phenol, tetrachloroethylene, and toluene while the sensor’s performance level varied among the compounds and sensor configurations. Among 40 tested sensor-configuration pairs, 11 showed high performance for acetaldehyde detection, 10 for acetone, 5 for tetrachloroethylene, 1 each for benzene, phenol, and toluene, while others showed medium to low performance. The test results revealed the limitations of most existing low-cost sensors including poor compound specificity, low sensitivity, low stability and poor accuracy. Future improvements are needed on sensing materials, on-chip signal processing, and interpretation of sensor data for IAQ assessment. These findings will help develop guidance for selecting and using low-cost VOC sensors for IAQ monitoring and control as well as for new sensor development and evaluation.

低成本和便携式挥发性有机化合物（VOC）传感器，如金属氧化物（MOx）传感器已经开发并在许多室内环境中实施。但是，对于这些传感器的准确性和可靠性以及如何解释这些传感器的数据，缺乏全面的研究。本研究旨在通过对当前低成本VOC传感器进行全面评估来解决这些知识和数据上的差距。通过对甲苯、甲醛、丙酮、二氯甲烷、四氯乙烯、1,1,1-三氯乙烷、间二甲苯、萘、乙醛、苯酚和苯等11种室内空气质量关注VOCs的稳定性、灵敏度、准确性、检出限和恢复时间，对传感器的性能和局限性进行了评估。开发了一种标准程序，用于在具有与实际室内环境条件相关的各种VOC浓度水平的50 L不锈钢室中调查传感器。总共测试了七种市面上现成的传感器，它们具有不同的工作温度和睡眠周期配置。根据传感器的灵敏度、精度和稳定性对传感器的性能进行了量化评价，并将其分为高、中、低三个等级。结果表明，6种传感器对以下化合物（乙醛、丙酮、苯、苯酚、四氯乙烯和甲苯）中的至少一种具有可靠的检测能力，而传感器的性能水平因化合物和传感器配置而异。在40个测试的传感器配置对中，11个对乙醛检测表现出高性能，10个对丙酮检测，5个对四氯乙烯检测，1个对苯、苯酚和甲苯检测，而其他的则表现出中低性能。测试结果揭示了现有大多数低成本传感器的局限性，包括化合物特异性差、灵敏度低、稳定性低和准确性差。未来需要在传感材料、芯片上信号处理和用于室内空气质量评估的传感器数据解释方面进行改进。这些发现将有助于为室内空气质量监测和控制以及新传感器的开发和评估选择和使用低成本VOC传感器提供指导。

The COVID-19 pandemic underscored the heightened risk of respiratory virus transmission in enclosed, densely populated environments. Aircraft cabins represent a unique setting, combining high ventilation and high-efficiency particulate air (HEPA) filtration with persistent uncertainty regarding dominant transmission routes. Using data from a documented long-haul in-flight outbreak, we developed a multi-route mechanistic model with Bayesian inference to quantify contributions of airborne, direct deposition, and contact transmission. Airborne transmission dominated, accounting for a median of 92.2% (95% credible interval [CrI]: 83.6–96.5%), whereas contact (7.8%, 95% CrI: 3.5–16.4%) and direct deposition (0.0%, 95% CrI: 0.0–0.1%) played minimal roles. Passengers seated within two rows of the index case had a 4.41-fold higher attack rate compared with those farther away (95% confidence interval [CI]: 1.98–9.81, P < 0.001), which our model reproduced through a simulated 5.00-fold (95% CrI: 2.10–12.86) higher risk in the same zone. Notably, 45% of observed infections occurred beyond this proximity, with our model predicting a comparable proportion (40%), indicating that long-range airborne transmission can persist even in highly ventilated cabins and underscoring limitations of contact tracing protocols. These findings provide quantitative evidence for SARS-CoV-2 transmission mechanisms in aircraft cabins and yield insights to guide risk assessment and infection control strategies in enclosed environments.

2019冠状病毒病大流行凸显了在封闭、人口密集的环境中呼吸道病毒传播的风险增加。飞机客舱是一个独特的环境，结合了高通风和高效微粒空气（HEPA）过滤，以及主要传播途径的持续不确定性。利用记录在案的长途飞行中爆发的数据，我们开发了一个多航线机制模型，并使用贝叶斯推理来量化空气传播、直接沉积和接触传播的贡献。空气传播占主导地位，中位数为92.2%(95%可信区间[CrI]: 83.6 ~ 96.5%)，接触（7.8%,95% CrI: 3.5 ~ 16.4%）和直接沉积（0.0%,95% CrI: 0.0 ~ 0.1%）的影响最小。与距离较远的乘客相比，坐在指数箱两排以内的乘客的攻击率高出4.41倍（95%置信区间[CI]: 1.98-9.81, P < 0.001），我们的模型通过模拟同一区域的5.00倍（95% CrI: 2.10-12.86）的风险来再现。值得注意的是，观察到的感染中有45%发生在这一距离之外，我们的模型预测了类似的比例（40%），这表明即使在高度通风的客舱中，远程空气传播也可能持续存在，并强调了接触者追踪协议的局限性。这些发现为SARS-CoV-2在机舱内的传播机制提供了定量证据，并为指导封闭环境中的风险评估和感染控制策略提供了见解。

In trying to solve the surge in carbon emissions (CO₂) caused by the growth in energy demand in Chinese public buildings (PB), scholars have focused on PB’s low-carbon development. However, existing research has mainly focused on the low-carbon benefits of buildings, with further investigation needed into user comfort and electricity pricing considerations. Therefore, this study develops a multi‑energy optimization framework to support low‑carbon transitions of Chinese PB while ensuring occupant thermal comfort and accounting for time‑of‑use (TOU) electricity pricing. Firstly, this study employs SketchUp and EnergyPlus to simulate the initial Energy Consumption (EC). Secondly, it develops four scenarios. Scenario 1 focuses solely on photovoltaic (PV) systems. Scenario 2 incorporates Ground-Source Heat Pumps (GSHP) as well as photovoltaics. Scenario 3 builds on Scenario 2 by improving the energy efficiency of the building envelope. Scenario 4 builds on Scenario 3 by incorporating TOU pricing. We then develop a multi-energy life-cycle cost-benefit (LCB) optimization model that includes carbon emission (ECO₂) reduction, which is solved using NSGA-II. Moreover, user behaviors are explicitly modelled and thermal comfort is quantified by Predicted Mean Vote and Predicted Percentage Dissatisfied indicators metrics to capture dynamic interactions among thermal comfort, EC and Electricity Price (EP). Results indicate Scenario 1 attains the lowest LCB, whereas Scenario 2 reduces ECO₂ by about 60.06% at a 53.25% higher LCB relative to Scenario 1, highlighting trade‑offs between cost and decarbonization. Scenario 4 is preferred by low‑carbon‑oriented stakeholders; cost‑sensitive users favor Scenario 1; balanced objectives point to Scenario 2. Under TOU, Scenario 4 moderates peak EC growth (7.83% at 10:00–12:00 vs. max 16.14% at 02:00–04:00). Global sensitivity analysis shows electricity price, peak sunlight hours and investment cost dominate system outcomes (sensitivity indices > 0.98). The findings provide practical guidance for prioritizing PV and GSHP deployment, envelope retrofits and TOU design to achieve comfort‑compliant, cost‑effective decarbonization of PB.

为了解决中国公共建筑因能源需求增长而导致的二氧化碳排放量激增的问题，学者们将重点放在了公共建筑的低碳发展上。然而，现有的研究主要集中在建筑的低碳效益上，需要进一步研究用户舒适度和电价考虑。因此，本研究开发了一个多能优化框架，以支持中国PB的低碳转型，同时确保乘员热舒适并考虑使用时间（TOU）电价。首先，本研究使用SketchUp和EnergyPlus模拟初始能耗（EC）。其次，开发了四种场景。场景1只关注光伏（PV）系统。方案2结合了地源热泵（GSHP）和光伏。方案3以方案2为基础，通过提高建筑围护结构的能源效率。通过合并TOU定价，场景4建立在场景3的基础上。然后，我们建立了包括碳排放（ECO2）减少在内的多能源生命周期成本效益（LCB）优化模型，并使用NSGA-II进行求解。此外，对用户行为进行了明确的建模，并通过预测平均投票和预测不满意百分比指标来量化热舒适，以捕捉热舒适、EC和电价（EP）之间的动态相互作用。结果表明，情景1的LCB最低，而情景2的LCB比情景1高53.25%，减少了约60.06%的ECO2，突出了成本和脱碳之间的权衡。低碳导向的利益相关者更倾向于情景4；对成本敏感的用户青睐场景1；平衡目标指向场景2。在分时电价下，情景4缓和了EC的峰值增长（10:00-12:00为7.83%，02:00-04:00为16.14%）。全局敏感性分析显示，电价、峰值日照时数和投资成本主导系统结果（敏感性指数>； 0.98）。研究结果为优先考虑PV和GSHP的部署、围护结构改造和TOU设计提供了实用指导，以实现符合舒适性和成本效益的PB脱碳。

Creating geometric digital twins of buildings remains a labor-intensive process, often limited to the reconstruction of structural elements. Non-structural components and their spatial relationships with indoor spaces are rarely integrated into a unified digital representation. This paper proposes a novel semi-automated method for generating graph-based geometric digital models for digital twins from 3D point cloud and image data. The approach extracts spatial and object information from these data based on deep learning methods. Multiple 2D detectors are trained on different public and customized datasets to broaden class coverage, and their predictions are mapped into a unified label space, fused per view, projected into 3D space, and merged into object instances that correspond to the same physical element. A new graph schema is then introduced to represent indoor spaces and elements, capturing both hierarchical and spatial relationships. The schema links each entity to its geometric representation and supports temporal snapshots. All extracted information is structured and stored in a graph database using the proposed schema. The method is validated on two real-world datasets, one residential house and one institutional facility, capturing a broader and more differentiated range of object classes across different building types and topologies. The promising results indicate that the method has the potential to be generalized to a wider range of buildings.

创建几何数字孪生建筑仍然是一个劳动密集型的过程，通常仅限于结构元素的重建。非结构构件及其与室内空间的空间关系很少整合到统一的数字表示中。提出了一种基于三维点云和图像数据的半自动化数字孪生几何模型生成方法。该方法基于深度学习方法从这些数据中提取空间和对象信息。多个2D检测器在不同的公共和定制数据集上进行训练，以扩大类别覆盖范围，它们的预测被映射到统一的标签空间，每个视图融合，投影到3D空间，并合并到对应于相同物理元素的对象实例中。然后引入一种新的图形模式来表示室内空间和元素，捕捉层次和空间关系。模式将每个实体链接到其几何表示，并支持时间快照。所有提取的信息都是结构化的，并使用提出的模式存储在图形数据库中。该方法在两个真实世界的数据集上进行了验证，一个是住宅，一个是机构设施，在不同的建筑类型和拓扑结构中捕获了更广泛、更有差异的对象类别。结果表明，该方法具有推广到更大范围建筑的潜力。

The metabolic rate (MET) is a fundamental parameter influencing thermal comfort, which further affects the well-being and productivity of the occupants. Here, the effects of activity intensity, ambient temperature, humidity, and barometric pressure on MET were studied. The results exhibited a quadratic relationship with temperature under most conditions when clothing insulation was fixed, but the ambient humidity had little effect on MET for Chinese young males. Barometric pressure influenced MET only below 80 kPa, where MET increased with decreasing pressure. In addition, a fundamental equation linking MET to walking speed was established, and based on this equation, temperature, clothing insulation correction, and barometric pressure correction were successively proposed. Validation against measured MET data from other studies showed an average relative error of 6.5% and a predictive reliability of 69.6%, demonstrating the equation’s superior predictive capability. Finally, a MET prediction equation for females was derived by replacing the fundamental equation, which maintained good predictive capability, highlighting the model's potential applicability. The obtained results were of great significance in promoting the development of MET measurement and estimation for future correction of thermal comfort standards.

代谢率（MET）是影响热舒适的基本参数，它进一步影响居住者的幸福感和生产力。本文研究了活动强度、环境温度、湿度和气压对MET的影响。当服装保温层固定时，大多数情况下与温度呈二次曲线关系，但环境湿度对中国青年男性MET的影响不大。大气压仅在80 kPa以下对MET有影响，且随气压降低MET增加。此外，建立了MET与步行速度的基本方程，并在此基础上提出了温度、服装保温校正和气压校正。根据其他研究的MET测量数据进行验证，平均相对误差为6.5%，预测信度为69.6%，表明该方程具有优越的预测能力。最后，通过替换基本方程推导出女性MET预测方程，保持了较好的预测能力，突出了模型的潜在适用性。所得结果对于促进MET测量和估算的发展，为今后热舒适标准的修正提供参考。

As essential public realms, street canyons play a critical role in shaping both pedestrian thermal comfort and the potential for solar energy utilization. In high-density urban settings, however, maintaining adequate solar access is increasingly constrained by intensive surrounding development. This study investigates the city of Wuxi, characterized by hot summers and cold winters, to explore how urban morphology influences seasonal solar radiation distribution. A ∼10 km² representative area was selected, encompassing three prototypical block typologies—setback towers, courtyard blocks, and linear blocks—each reflecting distinct development intensities. Parametric solar radiation simulations were performed using Grasshopper and Radiance to assess solar exposure on vehicular lanes and pedestrian sidewalks across different seasonal periods. Random Forest regression and SHAP (SHapley Additive exPlanations) analysis were employed to identify key morphological determinants of street-level solar access. The findings reveal that streets within courtyard block typologies receive 25.3%–26.3% less cumulative solar radiation compared to the other forms under equivalent conditions. Sidewalks consistently receive 4.2%–7.5% less radiation than adjacent carriageways.

作为必不可少的公共领域，街道峡谷在塑造行人热舒适和太阳能利用潜力方面发挥着关键作用。然而，在高密度的城市环境中，保持充足的太阳能供应越来越受到周围密集发展的限制。本研究以夏热冬冷的无锡市为研究对象，探讨城市形态对季节太阳辐射分布的影响。选择了一个10平方公里的代表性区域，包括三种典型的街区类型-挫折塔，庭院街区和线性街区-每一个都反映了不同的开发强度。利用Grasshopper和Radiance软件进行参数化太阳辐射模拟，评估不同季节车辆车道和人行道上的太阳辐射。采用随机森林回归和SHapley加性解释（SHapley Additive explanation）分析来确定街道太阳能接入的关键形态决定因素。研究结果表明，在同等条件下，庭院街区类型内的街道比其他形式的街道接收的累积太阳辐射少25.3%-26.3%。人行道受到的辐射始终比相邻的行车道少4.2%-7.5%。总体建筑强度与街道日照强度呈显著负相关（R²≈0.63），而单变量指标（如建筑覆盖率、高度）的预测价值有限。这些见解为早期城市设计决策提供了定量基础，使规划者能够优化街区类型，以增强密集城市环境中的太阳能性能。

The low oxygen, low temperature, and low humidity conditions prevalent in indoor environments at high altitudes can adversely affect personnel health and work efficiency. A control method was proposed in this study to deliver a multi-parameter coupled airflow, which was optimized for heat, humidity, and oxygen, directly to the facial breathing zone. This was achieved by positioning the oxygen supply terminals at specific locations above the workstation computer. An integrated experimental and numerical simulation approach was employed to investigate the effects of key supply air parameters on the localized environment, leading to the identification of the optimal operating conditions. It was demonstrated that this method successfully elevated the workspace oxygen concentration to 22.81% (from a 20% baseline) under optimal thermal-humidity conditions, while indoor humidity was stabilized at 0.072 kg/m³. Furthermore, an average oxygen enrichment velocity of 2.05% per minute and an personal oxygen inhalation efficiency of 64.12% were achieved. An effective technical solution for localized precision control in high-altitude office environments was presented in this study.

Elevated night-time temperatures in bedrooms on hot summer nights impairs sleep quality and sleep thermal comfort. Passive and low energy night-time cooling strategies can enhance individuals’ comfort without relying on air conditioning. This study evaluates the impact of a low-energy, water-based cooling mattress topper on sleep thermal comfort and quality in healthy adults sleeping in overheated UK bedrooms. Seventeen participants took part in repeated-measures controlled-bedroom experiments consisting of three stages: (1) baseline sleep in their own bedrooms under normal summer conditions, (2) sleep on a standard bedding system in a bedroom controlled at 30°C, and (3) sleep in the same overheated bedroom with the cooling mattress topper. Objective sleep metrics were recorded using wrist actigraphy, while subjective thermal comfort and sleep quality were assessed using validated questionnaires.

The cooling mattress topper was found to significantly improve sleep thermal comfort metrics (p < 0.05) with large effect sizes (r = 0.71 to 0.93). Substantial improvements in perceived sleep quality and a reduction in time spent awake were also reported. Actigraphy data showed that use of bed cooling restored total sleep time to baseline levels and reduced Sleep Onset Latency by ten minutes compared to using standard bedding. The findings suggest that targeted bed cooling is an effective, low-energy solution for mitigating sleep disruption in overheated bedrooms, and for mitigating the effects of increasing summertime temperatures in UK homes. There is an urgent need for sleep-specific overheating standards for UK homes.

在炎热的夏季夜晚，卧室夜间温度升高会损害睡眠质量和睡眠热舒适度。被动式和低能耗的夜间冷却策略可以提高个人的舒适度，而无需依赖空调。这项研究评估了低能耗、水基冷却床垫对在英国过热卧室中睡眠的健康成年人的睡眠热舒适和质量的影响。17名参与者参加了重复测量的受控卧室实验，包括三个阶段：(1)在正常夏季条件下在自己卧室的基线睡眠，(2)在30°C控制的卧室中使用标准床上用品系统睡眠，以及(3)在同一间过热的卧室中使用冷却床垫。使用手腕活动记录仪记录客观睡眠指标，使用有效问卷评估主观热舒适和睡眠质量。研究发现，降温床垫能显著改善睡眠热舒适指标（p < 0.05），且效应量较大（r = 0.71 ~ 0.93）。据报道，睡眠质量的显著改善和清醒时间的减少。活动记录仪数据显示，与使用标准床上用品相比，使用床上冷却将总睡眠时间恢复到基线水平，并将睡眠开始潜伏期减少了10分钟。研究结果表明，有针对性的床上降温是一种有效的、低能耗的解决方案，可以缓解过热卧室的睡眠中断，也可以缓解英国家庭夏季气温升高的影响。英国迫切需要制定针对睡眠过热的标准。

Intermittent solar radiation inside vehicle cabins causes rapid and non-uniform heating, yet its minute-scale impacts on occupants’ thermal perception and physiological responses remain insufficiently understood. A climatic chamber experiment was conducted with twenty adults exposed to simulated solar intensities of 200, 400, and 600 W·m⁻², two orientations (frontal, lateral), and durations of 1–3 min. Alternating light-shade cycles reproduced realistic driving conditions. Subjective votes (TSV, TCV) and physiological indicators (skin and core temperature, heart rate, salivary cortisol) were measured. Linear mixed-effects models considered within-subject dependence and exposure sequence. TSV increased linearly with irradiance (+0.55 ± 0.08 per 200 W·m⁻²) and stabilized within 2–3 min. Discomfort peaked on the forehead during frontal exposure. Skin temperature increased sharply and decayed with short post-shade lags (∼15 s). Heart rate rose by 5–8 bpm (p < 0.01), reflecting transient cardiovascular activation. Cortisol showed no irradiance main effect but displayed order-dependent variation, suggesting cumulative or adaptive endocrine responses. Minute-scale solar loading elicits rapid perceptual and localized physiological adjustments without elevating core temperature. Forehead heating and short thermal memory are key features of dynamic comfort in cabins. These findings provide empirical evidence to inform radiation-aware and predictive HVAC control strategies for energy-efficient thermal management in passenger vehicles.

汽车舱内的间歇性太阳辐射会引起快速且不均匀的加热，但其对乘员热感知和生理反应的微小影响仍未得到充分了解。在一个气候室实验中，20名成年人暴露在200、400和600 W·m（⁻²）两个方向（正面、侧面）的模拟太阳强度下，持续时间为1-3分钟。交替的光影循环再现了真实的驾驶条件。测量主观投票（TSV， TCV）和生理指标（皮肤和核心温度，心率，唾液皮质醇）。线性混合效应模型考虑受试者内部依赖性和暴露序列。TSV随辐照度（±0.55±0.08 / 200w·m）呈线性增加，并在2-3分钟内稳定下来。在正面暴露时，不适在额头上达到顶峰。皮肤温度急剧升高，并在短暂的遮光后滞后（~ 15 s）内腐烂。心率上升5 - 8bpm (p < 0.01)，反映了短暂的心血管激活。皮质醇不存在辐照主效应，但存在顺序依赖性变化，提示累积性或适应性内分泌反应。分尺度的太阳能负荷在不升高核心温度的情况下引起快速的感知和局部生理调节。前额加热和短热记忆是客舱动态舒适的主要特点。这些发现为客运车辆节能热管理的辐射感知和预测HVAC控制策略提供了经验证据。

This study investigates the distinct auditory perception patterns in autistic children compared to non-autistic peers, focusing on the impact of auditory stimuli on behavioural responses. We conducted a two-phase study: the first phase involved subjective assessments of auditory perception using tonal stimuli, whereas the second phase developed a personalised noise-control strategy based on these perceptions. The study enrolled 83 children in the autism group and 50 children in the comparison group, aged 7–12 years. Findings revealed that autistic children exhibited decreased tolerance to tonal stimuli starting at 40 dB HL. The perceived difference ranged from 5 dB to 20 dB, with 250 Hz showing the greatest difference to the comparison group. Clustering analysis identified distinct profiles within the autism group. The proposed auditory perception-based tuneable noise-cancelling headset was evaluated using everyday sound stimuli and was effective in mitigating unpleasant aural perception. A mobile application was introduced to facilitate real-time assessments and personalised interventions. After a three-week period of using the proposed headset, eighteen parents reported that they observed improvement in their children’s reaction to sensitive sound, while the other six parents did not observe any changes. The study's results highlight the importance of personalised auditory interventions to alleviate sensory overload and enhance the quality of life of autistic children.

本研究探讨了自闭症儿童与非自闭症儿童不同的听觉感知模式，重点研究了听觉刺激对行为反应的影响。我们进行了两阶段的研究：第一阶段涉及使用音调刺激对听觉感知的主观评估，而第二阶段则基于这些感知开发个性化的噪声控制策略。该研究招募了83名自闭症儿童和50名7-12岁的对照组儿童。研究结果显示，自闭症儿童对40 dB HL的音调刺激的耐受性下降。感知到的差异从5 dB到20 dB不等，其中250 Hz与对照组的差异最大。聚类分析确定了自闭症组中不同的特征。所提出的基于听觉感知的可调谐降噪耳机使用日常声音刺激进行评估，并有效减轻不愉快的听觉感知。引入了一个移动应用程序，以促进实时评估和个性化干预。在使用该耳机三周后，18位家长报告说，他们观察到孩子对敏感声音的反应有所改善，而其他6位家长没有观察到任何变化。这项研究的结果强调了个性化听觉干预对于减轻感官负荷和提高自闭症儿童生活质量的重要性。
