Thermochemical energy storage (TCES) can support decarbonising the building sector by offering high storage density and the potential for long-duration retention with low standing losses; it can be charged using low-grade solar or waste heat and discharged on demand for peak shaving and renewable integration, though realised benefits depend on material stability and system design. Because units are installed close to occupied buildings, occupant and worker safety is a primary criterion; material selection must therefore look beyond energy metrics to evaluate safety and sustainability. The Safe and Sustainable by Design (SSbD) framework provides a structured lens for such assessment. This study evaluates the applicability of SSbD to reaction-based TCES materials for buildings. A review of reviews in Scopus identifies 11 reviews and compiles 50 materials. Safety and hazard data are gathered from regulatory sources (ECHA, PubChem) and supplier safety data sheets. Life cycle inventories are screened via the Global Life Cycle Assessment Data Access network and supplemented by literature-based datasets and transparently documented proxies. Cost data are derived from supplier catalogues, market quotations, and literature. Readiness for SSbD assessment spans: 8/50 very high (e.g., CaCl₂·6H₂O, MgSO₄·7H₂O), 5/50 high (e.g., LiCl·H₂O, MgCl₂·6H₂O), 10/50 medium (e.g., Na₂S·5H₂O, SrBr₂·6H₂O), 3/50 low (MgSO₄·6H₂O, FeCl₂·2H₂O, CuCl₂·H₂O), and 24/50 not ready yet (mainly minor hydrates and all ammonia adducts). Cross-cutting gaps include PMT/vPvM indicators, selected chronic aquatic and endocrine endpoints, and basic occupational safety and health descriptors. The results provide an actionable evidence base for prioritising safer, sustainability-aligned TCES materials to support energy-efficient and climate-resilient buildings.

热化学储能（TCES）可以通过提供高存储密度和低站立损失的长期保留潜力来支持建筑部门的脱碳；它可以使用低品位的太阳能或废热充电，并根据调峰和可再生能源整合的需求排放，尽管实现的效益取决于材料稳定性和系统设计。由于机组安装在被占用建筑物附近，因此居住者和工人的安全是首要标准；因此，材料选择必须超越能源指标来评估安全性和可持续性。安全与可持续设计（SSbD）框架为这种评估提供了一个结构化的视角。本研究评估了SSbD对反应基TCES建筑材料的适用性。对Scopus上的评论进行审查，确定了11篇评论并汇编了50篇材料。安全和危害数据是从监管来源（ECHA, PubChem）和供应商安全数据表收集的。生命周期清单通过全球生命周期评估数据访问网络进行筛选，并辅以基于文献的数据集和透明记录的代理。成本数据来源于供应商目录、市场报价和文献。SSbD评估的准备程度范围为：8/50非常高（例如CaCl2·6H2O， MgSO4·7H2O）， 5/50高（例如LiCl·H2O， MgCl2·6H2O）， 10/50中等（例如Na2S·5H2O， SrBr2·6H2O）， 3/50低（MgSO4·6H2O, FeCl2·2H2O, CuCl2·H2O）， 24/50尚未准备好（主要是少量水合物和所有氨加合物）。跨领域差距包括PMT/vPvM指标、选定的慢性水生和内分泌终点以及基本职业安全和健康描述符。研究结果为优先考虑更安全、符合可持续性的TCES材料提供了可操作的证据基础，以支持节能和气候适应型建筑。

The study identifies smart glazing properties necessary for delivering net energy positive performance for office buildings. A comprehensive parametric framework is used to quantify the influence of smart window optical and thermal characteristics, tint control strategies, and building design parameters on whole-building energy performance. The analysis results demonstrate that smart glazed windows can transition from net energy liability to net energy positive elements of office building envelopes when climate-responsive control strategies and daylighting integration are appropriately implemented. Without daylighting control, smart glazed windows can increase annual energy use by up to 20% in cooling-dominated climates, whereas the deployment of daylighting control reduced total energy consumption by 5–7% in mixed climates such as Boulder, CO. Outdoor air temperature (OAT)-based control strategies consistently outperformed incident total solar-radiation (ITSR)-based controls, when coupled with optimal switching settings. Moreover, the sensitivity analyses reveal a nonlinear dependence of energy performance on window-to-wall ratio, with large windows increasing both the penalties and benefits of smart glazed fenestration systems. Improvements in thermal transmittance below 1.10 W/m²·K yielded diminishing returns, indicating that adaptive optical properties are more influential than ultra-low U-factors for achieving net energy positive performance for smart glazed windows. The evaluation of commercially available electrochromic glazing products when deployed to office buildings show energy savings of 2–5% for mild and mixed climates, near-neutral performance for cooling-dominated climates, and energy penalties for heating-dominated climates.

该研究确定了智能玻璃的特性，为办公大楼提供净节能性能所必需的。一个综合的参数框架被用来量化智能窗户的光学和热特性、色调控制策略和建筑设计参数对整个建筑能源性能的影响。分析结果表明，当气候响应控制策略和采光整合得到适当实施时，智能玻璃窗可以从办公建筑围护结构的净能源负向净能源正元素转变。在没有采光控制的情况下，智能玻璃窗可以在以凉爽为主的气候条件下每年增加20%的能源消耗，而在混合气候条件下，如科罗拉多州博尔德，采光控制的部署可以减少5-7%的总能源消耗。室外空气温度（OAT）控制策略始终优于基于入射总太阳辐射（ITSR）的控制策略，当与最佳开关设置相结合时。此外，敏感性分析揭示了能量性能与窗墙比的非线性依赖关系，大窗户增加了智能玻璃开窗系统的损失和收益。当热透射率低于1.10 W/m2·K时，收益递减，这表明自适应光学特性比超低u系数对智能玻璃窗实现净能量正性能的影响更大。对商用电致变色玻璃产品的评估表明，在温和气候和混合气候下，电致变色玻璃产品可以节省2-5%的能源，在以冷为主的气候下，电致变色玻璃的性能接近中性，而在以热为主的气候下，电致变色玻璃的能源消耗减少。

To address the inherent limitation of traditional solar chimneys—where ventilation efficiency is constrained by their heavy reliance on single-sided heating—this study explores the performance enhancement potential of integrating transparent glass inserts. Employing a synergistic approach combining experimental tests and Computational Fluid Dynamics (CFD) simulations, the research clarifies the nonlinear coupling mechanism between the insert-induced efficiency improvement and key geometric parameters (i.e., chimney depth and height).

In the experimental phase, an electrically heated aluminum plate was used as a controllable heat source to avoid external weather interference, with benchmark tests conducted on ventilation performance under three depths (0.2, 0.3, 0.4 m) with/without inserted plates at constant power. In CFD simulations, 500 W/m² incident solar radiation was applied to the glass outer surface as a boundary condition. Extended simulations were further performed to systematically investigate the impacts of chimney height (1.0–2.2 m), depth-to-height ratio and plate length ratio (λ) on ventilation performance.

The results demonstrate that the integration of transparent inserts double the effective plume area, thereby reducing flow resistance and significantly enhancing the mass flow rate. While, the ventilation rate increases monotonically with both chimney depth and height, but the relative efficiency increment exhibits a distinct nonlinear characteristic, with an optimal depth-to-height ratio of 0.1–0.3. Additionally, optimizing λ to 0.8 effectively the formation of bottom recirculation vortices, leading to a further 7% improvement in ventilation rate. This study not only provides actionable design optimization guidelines for solar chimney systems but also reveals the intrinsic coupling mechanism among geometric parameters, built-in components, and flow field structures, thereby laying a solid theoretical foundation for the development of high-performance passive ventilation technologies in buildings.

为了解决传统太阳能烟囱的固有局限性，即通风效率受到严重依赖单面加热的限制，本研究探索了集成透明玻璃嵌套的性能增强潜力。采用实验测试与计算流体力学（CFD）模拟相结合的协同方法，阐明了插入效率提高与关键几何参数（烟囱深度和高度）之间的非线性耦合机制。在实验阶段，采用电热铝板作为可控热源，避免外界天气干扰，在恒定功率下，对有无插板在三种深度（0.2、0.3、0.4 m）下的通风性能进行基准测试。在CFD模拟中，在玻璃外表面施加500 W/m2的入射太阳辐射作为边界条件。进一步进行了扩展模拟，系统地研究了烟囱高度（1.0-2.2 m）、深高比和板长比（λ）对通风性能的影响。结果表明，透明插片的集成使有效羽流面积增加了一倍，从而降低了流动阻力，显著提高了质量流量。通风量随烟囱深度和烟囱高度单调增加，但相对效率增量表现出明显的非线性特征，最佳深高比为0.1 ~ 0.3。此外，优化λ至0.8有效地形成底部再循环涡，导致通风率进一步提高7%。本研究不仅为太阳能烟囱系统提供了可操作的设计优化指导，而且揭示了几何参数、内建构件、流场结构之间的内在耦合机制，为建筑高性能被动通风技术的发展奠定了坚实的理论基础。

With the increasing frequency of extreme heat events and the intensification of the urban heat island effect, thermal safety for children in outdoor urban environments has become a critical concern. Traditional heat stress indicators have limited applicability for early adolescents, leading to ambiguous predictions. Using experimental data collected from 36 junior high school students (aged 12 ± 1 years) in Nanning, China, from June to August 2024, we introduced an enhanced two-node model integrated with a genetic algorithm to predict and mitigate heat stress. Through real-time monitoring of core/skin temperatures and microclimate data via wireless sensors and a mobile thermal comfort device, four key physiological parameters in the model were optimized. The optimized model improved the predictive accuracy for group trends in skin and core temperatures, reducing the RMSE by 76.07% and 75.86%, respectively. Furthermore, by incorporating six spatial scenarios with different shading conditions and underlying surfaces into ENVI-met, the model quantitatively revealed significant effects of various environmental factors on the body temperature changes of early adolescents (p < 0.05). This study lays a theoretical foundation for evidence-based child-friendly design strategies and provides scientific support for protecting adolescents’ health in the context of climate change.

随着极端高温事件的频繁发生和城市热岛效应的加剧，儿童在城市室外环境中的热安全已成为人们关注的焦点。传统的热应激指标对早期青少年的适用性有限，导致预测不明确。利用2024年6月至8月对中国南宁市36名（12±1岁）初中生的实验数据，提出了一种结合遗传算法的增强型双节点模型来预测和缓解热应激。通过无线传感器和移动热舒适装置实时监测核心/皮肤温度和小气候数据，优化模型中的四个关键生理参数。优化后的模型提高了皮肤和核心温度群体趋势的预测精度，RMSE分别降低了76.07%和75.86%。此外，通过将6种不同遮阳条件和下垫面的空间情景纳入ENVI-met，该模型定量揭示了不同环境因素对早期青少年体温变化的显著影响（p < 0.05）。本研究为基于证据的儿童友好型设计策略提供理论基础，为气候变化背景下保护青少年健康提供科学支持。

With population aging, improving the winter outdoor thermal comfort of older adults with chronic diseases in historic urban districts is important for health and for sustainable urban renewal. Focusing on two representative sites—Jinli in Chengdu (southern group, hot summer–cold winter) and Buzili in Zhangjiakou (northern group, cold zone), we combined micrometeorological measurements with questionnaires, obtaining 1,512 valid older adult samples. Physiologically Equivalent Temperature (PET) was used to assess winter thermal perception, and machine learning models were applied to identify key influencing factors. Results indicate that the northern group has a Neutral Physiologically Equivalent Temperature (NPET) of 7.4℃ and a thermally acceptable range (TAR) of 1.90–14.66℃, whereas the southern group has an NPET of 12.3℃ and a TAR of 8.93–18.51℃. Random Forest performed best for predicting Thermal Sensation Vote (TSV) (north R² = 0.804, south R² = 0.867). SHapley Additive exPlanations (SHAP) translated qualitative directions into indicative intervals: V_a exceeds about 2.0 m/s it markedly shifts TSV toward “colder”, whereas keeping near ground V_a within 1–1.5 m/s lowers risk; in the south, when RH reaches about 80% or higher and T_a is above about 12℃, the marginal warming effect of temperature increase alone attenuates, suggesting a priority for dehumidification plus moderate warming. PM2.5 and PM10 showed a negative association with Thermal Comfort Vote (TCV) in the north. This study provides winter thermal benchmarks and quantifies the context sensitivity of temperature–wind/humidity couplings into practice oriented indicative intervals, enhancing health levels for elderly individuals with chronic diseases in historic districts.

随着人口老龄化，改善历史城区老年人冬季室外热舒适对健康和城市可持续更新具有重要意义。以成都金里（南组，夏热冬冷）和张家口布子里（北组，寒区）两个代表性站点为研究对象，采用微气象测量与问卷调查相结合的方法，获取有效老年人样本1512份。使用生理等效温度（PET）评估冬季热感知，并应用机器学习模型识别关键影响因素。结果表明，北侧组的中性生理等效温度（NPET）为7.4℃，热可接受范围（TAR）为1.90 ~ 14.66℃，而南侧组的NPET为12.3℃，TAR为8.93 ~ 18.51℃。随机森林对热感觉投票（TSV）的预测效果最好（北R2 = 0.804，南R2 = 0.867）。SHapley加性解释（SHAP）将定性方向转化为指示区间：Va超过2.0 m/s， TSV明显向“更冷”方向移动，而保持近地Va在1-1.5 m/s内降低风险；在南方，当RH达到80%以上，Ta在12℃以上时，单纯增温的边际增温效应减弱，应优先进行除湿+适度增温。在北方，PM2.5和PM10与热舒适指数呈负相关。该研究提供了冬季热基准，并将温度-风/湿度耦合的上下文敏感性量化为面向实践的指示区间，为历史街区的小气候优化和年龄友好型设计提供了证据

This study provides winter thermal benchmarks and quantifies the context sensitivity of temperature–wind/humidity couplings into practice oriented indicative intervals, enhancing health levels for elderly individuals with chronic diseases in historic districts.</div></div>","PeriodicalId":11641,"journal":{"name":"Energy and Buildings","volume":"357 ","pages":"Article 117131"},"PeriodicalIF":7.1,"publicationDate":"2026-02-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"146146606","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}
