Space cooling demand in Europe is on the rise, yet systematic assessments of how passive measures can moderate this growth remain scarce. Passive measures such as shading, glazing, and ventilation reduce cooling demand by limiting heat gains without relying on active energy use. This study evaluates their techno-economic potential across the EU-27 using a bottom-up building stock model. By linking energy savings with investment needs, we construct country-level cost curves that establish a merit order for implementation. Results show that shading and glazing upgrades are the most cost-effective measures, with multi-family buildings delivering higher savings at lower costs than single-family houses. Regional differences are notable: Mediterranean countries show limited additional headroom, while Central and Northern Europe retain larger unrealized potentials. The findings provide policymakers with a practical roadmap for integrating passive cooling into national renovation plans and local energy plans, thereby supporting the long-term objectives of European energy and building directives.
欧洲的空间降温需求正在上升,但关于被动措施如何减缓这一增长的系统评估仍然很少。被动措施,如遮阳、玻璃和通风,通过限制热量的增加来减少冷却需求,而不依赖于主动能源的使用。本研究使用自下而上的建筑存量模型评估了欧盟27国的技术经济潜力。通过将节能与投资需求联系起来,我们构建了国家层面的成本曲线,为实施建立了价值顺序。结果表明,遮阳和玻璃升级是最具成本效益的措施,与单户住宅相比,多户住宅的成本更低,节省的成本更高。区域差异是显著的:地中海国家显示出有限的额外空间,而中欧和北欧则保留了较大的未实现潜力。研究结果为决策者提供了一个实用的路线图,将被动式冷却纳入国家改造计划和地方能源计划,从而支持欧洲能源和建筑指令的长期目标。

Mitigating energy consumption for transparent building envelopes has emerged as a crucial strategy for improving building energy efficiency in recent years. Although electrochromic (EC) windows dynamically regulate their Solar Heat Gain Coefficient (SHGC) to reduce heating and cooling loads, the comprehensive optimization of control strategies remains underexplored in architectural implementations. This study integrates building energy simulations with the Entropy Weight Method (EWM) to assess the EC glazing performance under diverse control strategies through multi-objective evaluation. Three strategies of solar radiation-based, window surface temperature-based, and indoor daylight illuminance-based control were implemented to dynamically modulate the optical properties of EC glass. Key metrics including building energy consumption, daylight performance, and thermal comfort indices were analyzed to establish practical guidelines for varied building orientations across the climatic zones in China. Results demonstrates that under optimized control conditions, annual cooling energy consumption decreased by 32%, daylight glare index (DGI) satisfaction increased threefold and predicted mean vote compliance improved by 10% compared to conventional glazing in Shanghai. Notably, control strategies based on indoor illuminance with a colorization threshold of 300 lx achieved superior daylight comfort and glare reduction across most orientations. Rational control strategies enable EC smart window to outperform conventional counterparts in most climatic regions, providing dual benefits of enhanced occupant comfort and building energy efficiency.
近年来,减少透明建筑围护结构的能源消耗已成为提高建筑能源效益的一项重要策略。虽然电致变色(EC)窗口动态调节其太阳热增益系数(SHGC)以减少加热和冷却负荷,但在建筑实现中,控制策略的综合优化仍有待探索。本研究将建筑能耗模拟与熵权法(EWM)相结合,通过多目标评价来评估不同控制策略下EC玻璃的性能。采用基于太阳辐射、窗面温度和室内照度的三种控制策略对EC玻璃的光学性能进行动态调节。分析了建筑能耗、日光性能和热舒适指数等关键指标,为中国不同气候带的建筑朝向建立实用指南。结果表明,在优化控制条件下,与传统玻璃相比,上海的年冷却能耗降低了32%,日光眩光指数(DGI)满意度提高了三倍,预测平均投票合规率提高了10%。值得注意的是,基于室内照度的控制策略,颜色阈值为300 lx,在大多数方向上实现了卓越的日光舒适性和眩光减少。合理的控制策略使EC智能窗在大多数气候地区的表现优于传统的智能窗,提供了增强居住者舒适度和建筑能效的双重好处。

This study aims to optimise the thermal performance and space efficiency of Cold Thermal Energy Storage (CTES) systems using a beneficial and unbeneficial probability utility index analysis. The optimisation framework simultaneously minimises complete solidification time (St) and complete melting time (Mt), while maximising the compactness factor (C). The effects of fin height, fin spacing, and fin thickness on heat transfer performance and system compactness are systematically evaluated. The optimisation results identify an optimal configuration with a fin height of 10 mm, a fin spacing of 2.4 mm, and a fin thickness of 0.75 mm, resulting in an enhancement in heat transfer efficiency and a reduction in both solidification and melting times compared to the baseline design reported in the literature. Sensitivity analysis indicates that fin height is the dominant parameter, contributing 95.8% to overall thermal performance, followed by fin spacing (2.75%) and fin thickness (0.94%). The proposed methodology provides a robust and systematic framework for balancing thermal efficiency, compactness, and response time in CTES systems. These findings offer practical design guidelines for high-performance CTES applications in refrigeration, air conditioning, and peak-load shifting, and support future advancements in cold thermal energy storage technologies.
本研究旨在利用有利和不利的概率效用指数分析来优化冷热储能(CTES)系统的热性能和空间效率。优化框架同时最小化了完全凝固时间(St)和完全熔化时间(Mt),同时最大化了致密系数(C)。系统地评价了翅片高度、翅片间距和翅片厚度对传热性能和系统紧凑性的影响。优化结果确定了最佳配置,翅片高度为10 mm,翅片间距为2.4 mm,翅片厚度为0.75 mm,与文献中报道的基线设计相比,传热效率提高,凝固和熔化时间缩短。灵敏度分析表明,翅片高度是主导参数,对整体热性能的贡献为95.8%,其次是翅片间距(2.75%)和翅片厚度(0.94%)。所提出的方法为平衡CTES系统的热效率、紧凑性和响应时间提供了一个强大的系统框架。这些发现为高性能CTES在制冷、空调和峰值负荷转移方面的应用提供了实用的设计指南,并支持未来冷热储能技术的发展。

Renovation of existing buildings to meet Nearly Zero Energy Building (NZEB) standards is essential for reducing energy consumption and CO2 emissions in the residential sector, making it a central strategy for achieving national climate goals. While commonly applied renovation measures effectively reduce operational energy consumption and CO2 emissions, they may increase the building’s environmental impact due to embodied emissions from construction materials and equipment. To address these opposing effects, this study employs a life cycle-oriented multi-objective optimization (MOO) approach to identify optimal renovation strategies for a representative collective residential building. A Definitive Screening Design (DSD) is used to create a minimal simulation experiment, and regression analysis is applied to develop surrogate models that define the relationships between primary energy consumption (PE), life cycle emissions (LCE), life cycle cost (LCC), and the considered renovation measures. These surrogate models are integrated into the MOO model, which is optimized using the NSGA-III algorithm to simultaneously minimize PE, LCE, and LCC. The resulting Pareto-optimal solutions reveal distinct trade-offs, characterized by a non-linear positive relationship between PE and LCE, a linear negative relationship between PE and LCC, and a non-linear negative relationship between LCE and LCC. These relationships indicate that improvements in energy and environmental performance are associated with significant cost increases. To evaluate and rank the Pareto-optimal solutions, the hybrid Entropy-TOPSIS method is applied, resulting in the selection of an optimal renovation strategy with its corresponding set of renovation measures. The proposed methodology provides an efficient decision-support approach for renovating collective residential buildings following NZEB standards.
改造现有建筑以满足近零能耗建筑(NZEB)标准对于减少住宅部门的能源消耗和二氧化碳排放至关重要,使其成为实现国家气候目标的核心战略。虽然通常采用的改造措施有效地降低了运营能耗和二氧化碳排放,但由于建筑材料和设备的隐含排放,它们可能会增加建筑物对环境的影响。为了解决这些相反的影响,本研究采用面向生命周期的多目标优化(MOO)方法来确定具有代表性的集体住宅建筑的最佳改造策略。采用确定性筛选设计(DSD)创建最小模拟实验,并应用回归分析开发替代模型,定义一次能源消耗(PE)、生命周期排放(LCE)、生命周期成本(LCC)和考虑的改造措施之间的关系。将这些代理模型集成到MOO模型中,使用NSGA-III算法对MOO模型进行优化,以同时最小化PE、LCE和LCC。所得到的帕累托最优解揭示了不同的权衡,其特征是PE与LCE之间存在非线性正相关关系,PE与LCC之间存在线性负相关关系,LCE与LCC之间存在非线性负相关关系。这些关系表明,能源和环境绩效的改善与成本的显著增加有关。为了对pareto最优解进行评价和排序,采用混合熵- topsis方法,选择最优改造策略及其相应的改造措施集。提出的方法为符合NZEB标准的集体住宅改造提供了有效的决策支持方法。

The global push for carbon neutrality has intensified the need for rapid and accurate energy prediction methods for BIPV-integrated modular buildings. Traditional physics-based simulation approaches suffer from excessive computational burden. This study presents a novel machine learning-based rapid energy prediction methodology specifically designed for modular buildings with building-integrated photovoltaics. A comprehensive feature engineering framework captures the unique thermal and geometric characteristics of modular construction through six-surface property encoding, geometric parameters, and solar irradiance calculations. The methodology employs a modular building decomposition strategy that enables individual module analysis while maintaining system-level accuracy. An XGBoost-based prediction model achieves superior performance across four representative climate zones. The model achieves R2 values exceeding 0.93 for heating loads, cooling loads, and total energy consumption. Experimental validation using a real-world BIPV-integrated modular building demonstrates prediction accuracy within industry-acceptable limits, with mean absolute errors below 1.5°C. The computational efficiency assessment shows prediction speeds over 2,000 × faster than traditional simulation approaches, enabling real-time design iteration.

Traditional physics-based simulation approaches suffer from excessive computational burden. This study presents a novel machine learning-based rapid energy prediction methodology specifically designed for modular buildings with building-integrated photovoltaics. A comprehensive feature engineering framework captures the unique thermal and geometric characteristics of modular construction through six-surface property encoding, geometric parameters, and solar irradiance calculations. The methodology employs a modular building decomposition strategy that enables individual module analysis while maintaining system-level accuracy. An XGBoost-based prediction model achieves superior performance across four representative climate zones. The model achieves R<sup>2</sup> values exceeding 0.93 for heating loads, cooling loads, and total energy consumption. Experimental validation using a real-world BIPV-integrated modular building demonstrates prediction accuracy within industry-acceptable limits, with mean absolute errors below 1.5°C. The computational efficiency assessment shows prediction speeds over 2,000 × faster than traditional simulation approaches, enabling real-time design iteration.
