Due to the high consumption of fossil fuels and the environmental challenges the world is facing, the transition towards renewable energies has become increasingly evident. Thus, enhancing the performance of different renewable energy systems became a fundamental research focus. Improving the annual solar photovoltaic systems efficiencies became a critical need to maintain system performance and durability. The major challenge facing solar photovoltaic system technology to be controlled and reduced is the overheating of the solar cells, where this factor not only affects panel efficiency but also causes heat-induced structural damages, and long-term exposure which may accelerate material degradation, reduce panel lifespan, and potentially develop hot spots. Among the different solutions is the use of phase change materials. This research demonstrates detailed recent literature review alongside with the appropriate classifications and critical analysis related to four distinct PCM-based cooling systems: pure PCM, composite PCM, finned PCM, and hybrid PCM systems. These PCM systems affect solar system efficiency, electrical power generation, and temperature. Findings revealed that hydrated salt HS36 and paraffin wax RT42 in pure PCM systems can highly enhance system electrical efficiency, as well as enhancements achieved through composite PCM systems incorporating multiwall carbon, graphene nanoplatelets, and magnesium oxide. Moreover, finned PCM integrated with zinc nanoparticles and aluminum fins, demonstrated promising efficiency improvements. On the other hand, hybrid PCM systems, such as PVT-RT35HC integrated with graphene nanoparticle nanofluids, show significant efficiency gains and electrical power enhancements, knowing that the majority of studies performed during the last three years were introducing hybrid cooling systems integrated with phase change materials. This research article shows the potential of PCM-based cooling solutions in advancing renewable energy technologies and covers a comprehensive review that goes through the recent studies of the last three years about employing phase-change materials as a cooling system for solar cells through different ways that can be classified into four main categories which are pure PCM, composite PCM, finned PCM and hybrid cooling systems.

由于化石燃料的高消耗和世界面临的环境挑战，向可再生能源的过渡日益明显。因此，提高不同可再生能源系统的性能成为基础研究的重点。提高太阳能光伏系统的年度效率成为维持系统性能和耐用性的关键需求。太阳能光伏系统技术面临的主要挑战是控制和减少太阳能电池的过热，这一因素不仅影响面板效率，而且会引起热致结构损伤，长期暴露可能会加速材料降解，降低面板寿命，并可能产生热点。在不同的解决方案中，相变材料的使用是其中之一。本研究展示了详细的近期文献综述，以及与四种不同的PCM冷却系统相关的适当分类和关键分析：纯PCM，复合PCM，鳍状PCM和混合PCM系统。这些PCM系统影响太阳能系统的效率、发电和温度。研究结果表明，在纯PCM系统中加入水合盐HS36和石蜡RT42可以大大提高系统的电效率，而通过加入多壁碳、石墨烯纳米片和氧化镁的复合PCM系统也可以提高系统的电效率。此外，与锌纳米颗粒和铝鳍相结合的鳍状PCM显示出有希望的效率提高。另一方面，混合PCM系统，如集成石墨烯纳米颗粒纳米流体的PVT-RT35HC，显示出显着的效率提高和电功率增强，知道在过去三年中进行的大多数研究都是引入集成相变材料的混合冷却系统。这篇研究文章展示了基于PCM的冷却解决方案在推进可再生能源技术方面的潜力，并全面回顾了过去三年关于采用相变材料作为太阳能电池冷却系统的最新研究，这些研究通过不同的方式可分为纯PCM、复合PCM、翅片PCM和混合冷却系统四大类。

Price decrease of photovoltaic (PV) energy in recent years allows to an increase in the use of small-scale PV modules, especially in the residential sector. Considering that houses and buildings are exposed to solar radiation during the day, it is possible to generate electricity by installing PV modules at strategic locations within the construction, using facades, windows, walls and roofs as Building Integrated Photovoltaic (BIPV) applications. Based on the above, it is analyzed the geometry of Colombian terraces corresponding to an area located on top of houses and buildings, which have flat open spaces that serve as roofs. Uses of terraces are related to drying clothes and cultivation; therefore, it is possible assign a portion of the entire area to the generation of electricity from the installation of PV modules. Occupation area due to integrated BIPV applications, is an important issue and is often limited to the flat geometry of most commercial solar panels. Thus, the goal of this work, is to generate curved photovoltaic surfaces that maximize the area exposed to the sun, seeking to increase the power of radiation captured and using the same area of occupation of conventional PV modules. To achieve this, a Genetic Algorithm (GA) is integrated into a computational ray tracing tool, in order to evaluate the radiation captured by a set of surfaces, which have a projected flat area on the terrace of

1 m^{2}

, considering historical irradiance data in Medellín, Colombia. The optimal PV surface obtained, presents an additional 19.3% of captured energy and an additional area of 28% compared to the flat geometry. This is a promising finding because it shows a direct relationship between radiation capture and the geometric shape of the PV surface. The performance of the Optimal PV surface is validated and compared with flat geometry using TracePro.

近年来光伏（PV）能源价格的下降使得小型光伏组件的使用增加，特别是在住宅部门。考虑到房屋和建筑物在白天暴露在太阳辐射下，可以通过在建筑物内的战略位置安装光伏模块来发电，使用立面，窗户，墙壁和屋顶作为建筑集成光伏（BIPV）应用。在此基础上，分析了哥伦比亚露台的几何形状，这些露台对应于位于房屋和建筑物顶部的区域，这些区域具有作为屋顶的平坦开放空间。梯田的用途与晒衣服和耕作有关；因此，可以将整个区域的一部分分配给安装光伏模块发电。由于集成BIPV应用，占用面积是一个重要的问题，并且通常限于大多数商用太阳能电池板的平面几何形状。因此，这项工作的目标是产生弯曲的光伏表面，最大限度地增加暴露在太阳下的面积，寻求增加捕获的辐射功率，并使用与传统光伏模块相同的占用面积。为了实现这一目标，将遗传算法（GA）集成到计算光线追踪工具中，以评估一组表面捕获的辐射，这些表面在1平方米的露台上有一个投影平坦区域，考虑到哥伦比亚Medellín的历史辐照度数据。与平面几何结构相比，获得的最佳PV表面提供了额外19.3%的捕获能量和28%的额外面积。这是一个很有希望的发现，因为它显示了辐射捕获和PV表面几何形状之间的直接关系。利用TracePro对优化PV曲面的性能进行了验证，并与平面几何进行了比较。

Deep geothermal heat exchangers (DGHEs) have emerged as a potential approach to exploiting geothermal energy as a stable high-temperature heat source for ground-coupled heat pumps. This study aimed to offer insights into the heat transfer of DGHEs by systematic numerical simulations. This study first created a finite-volume model (FVM) for the heat transfer of DGHEs, which uses the governing equations of circulating fluid inside the borehole as a time-varying boundary condition for the borehole wall. The FVM model was verified by comparison with several reported models. The heat transfer analysis emphasized the validity of the homogeneous-medium assumption about the ground and the time-varying characteristics of the heat flux on the borehole wall. The homogeneous-medium assumption seems to be only acceptable in cases of limited thermal conductivity differences between the ground layers (e.g., < 2.0 W/m·K). Not only the heat flux on the borehole wall varies linearly with borehole depth, but the slope and the interception of the line are linear functions of the logarithm of time.

深层地热换热器（DGHEs）作为一种稳定的高温热源，已成为利用地热能的一种潜在方法。本研究旨在通过系统的数值模拟来深入了解DGHEs的传热。本研究首先建立了DGHEs传热的有限体积模型（FVM），该模型使用井内循环流体的控制方程作为井壁的时变边界条件。通过与几个已报道的模型的比较，验证了FVM模型的正确性。传热分析强调了地面介质均匀假设的正确性和井壁热流的时变特性。均匀介质假设似乎只有在地层之间导热系数差异有限的情况下才可以接受(例如，<；2.0 W / m·K)。井壁热流不仅随井深呈线性变化，而且斜率和截距也是时间对数的线性函数。

To address global challenge of climate changes, renewable energy has been fully developed in recent years. However, renewable energy is usually intermittent which makes it challenging for application. Liquid air energy storage can effectively store intermittent energy with promising prospects. Liquid air is a mixture composed of N₂, O₂ and Ar with different evaporation temperatures. It is assumed to form temperature and concentration stratification during storage and thus causes safety challenge. To address this issue, molecular dynamics (MD) simulation method is used to study the temperature and concentration distribution characteristics in liquid air. The results show that the system temperature remains constant at 94 K with no temperature stratification during storage. However, the concentration of liquid air changes along vertical direction (z axis): the oxygen concentration remains stable around 21 % as z is 0–60 Å, rises to 22.1 % as z is from 60 to 70 Å and drops to 0 % as z is above 80 Å. The thin and short stratification phenomenon occurs at the gas-liquid interface region. In addition, a higher heat flux leads to a higher evaporation rate and a larger oxygen concentration. As the heat flux increases from 0.0 to 2.4 W/m², evaporation rate rises from 0.13 to 0.2 % and the oxygen concentration at the liquid-gas interface reaches 22.3 %. Thus, concentration stratification exists during liquid air storage and should be treated carefully. This paper provides an insight into the temperature and concentration distribution of liquid air during storage and is significant for safety improvement and development of liquid air energy storage.

为应对气候变化这一全球性挑战，近年来可再生能源得到了充分发展。然而，可再生能源通常是间歇性的，这使得它的应用具有挑战性。液态空气储能能有效地存储间歇能，具有广阔的应用前景。液态空气是由不同蒸发温度的N2、O2和Ar组成的混合物。假定在贮存过程中会形成温度和浓度分层，从而给安全带来挑战。为了解决这一问题，采用分子动力学（MD）模拟方法研究了液态空气中的温度和浓度分布特征。结果表明：在贮存过程中，体系温度保持在94 K不变，无温度分层现象；然而，液态空气的浓度沿垂直方向（z轴）变化：当z为0 - 60时，氧浓度稳定在21%左右Å，当z为60 - 70时，氧浓度上升到22.1% Å，当z大于80时，氧浓度下降到0% Å。在气液界面区出现薄而短的分层现象。此外，较高的热通量导致较高的蒸发速率和较大的氧浓度。当热流密度从0.0 W/m2增加到2.4 W/m2时，蒸发速率从0.13%增加到0.2%，液气界面氧浓度达到22.3%。因此，液体空气储存过程中存在浓度分层现象，应谨慎处理。研究了液体空气在储存过程中的温度和浓度分布，对提高液体空气储能的安全性和发展具有重要意义。

Thermal bridges may represent up to 50 % of the building's envelope area and may increase the energy consumption of buildings by up to 30 %, however their impact is often not taken into account adequately in China. In this study, the energy performance of a typical two-story residential building under four different Chinese climate zones is investigated using WUFI Plus program in terms of annual heating and cooling energy demands. Several typical thermal bridges were taken into consideration. Two methods were used to evaluate the effect of thermal bridges on the building energy performance, the simplified method commonly used in China and the dynamic 3D modelling method, and were compared to do not consider thermal bridge. Also, two different types of building envelope, brick wall and aerated concrete wall, were used to evaluate the effect. The results show that by taking into account the thermal bridges, the annual heating energy demands of residential building increase 21.2 %, 24.8 %, 27.8 %, and 16.6 % under the four Chinese climate zones. Therefore, attention should be paid in the building envelope design to reduce thermal bridges. Compared to the dynamic 3D modelling method, the simplified method underestimates annual heating and cooling energy demands.

热桥可能占到建筑围护结构面积的50%，并可能使建筑的能耗增加30%，但在中国，它们的影响往往没有得到充分的考虑。本研究以中国四种不同气候带下典型两层住宅建筑的能源性能为研究对象，采用WUFI Plus程序对其年度供暖和制冷能源需求进行了研究。考虑了几种典型的热桥。采用国内常用的简化法和动态三维建模法两种方法来评价热桥对建筑能源性能的影响，并与不考虑热桥的方法进行比较。此外，还采用两种不同类型的建筑围护结构，砖墙和加气混凝土墙，对效果进行了评价。结果表明：考虑热桥后，中国4个气候带居住建筑年采暖能源需求分别增加21.2%、24.8%、27.8%和16.6%。因此，在建筑围护结构设计中应注意减少热桥。与动态三维建模方法相比，简化方法低估了年供暖和制冷能源需求。

The energy systems of public institutions experience unsatisfactory actual operation and improper operation management, and the level of building energy consumption is increasing annually. Research on the application of key energy-saving technologies in public institutions is an effective method to improve building energy efficiency and reduce energy wastage. In this study, the aperformance of key energy-saving technologies in public institutions were considered as the research object. Combined with the characteristics of different energy-saving technologies and relevant national standards, the evaluation indices were selected from four aspects: comprehensive energy efficiency, economy, environment, and operation management. According to the results of expert investigations and measured data, the index weight was determined using the artificial neural network and expert scoring methods, and a complete evaluation system of indices was built. There were 4 first-level, 10 second-level, and 11 third-level evaluation indices in the evaluation system. The evaluation indices of each level with the largest weights were the comprehensive energy efficiency of the buildings (0.532), technical energy efficiency (0.331), and water pump power consumption to heat (cold) transmission ratio (0.167). The evaluation system for key energy-saving technologies in public institutions is useful for operation managers to identify the weak points of system operations and formulate timely optimisation schemes. This evaluation system can be used as a valuable reference for improving the energy-saving levels of public institutions.

事业单位能源系统实际运行不理想，运行管理不当，建筑能耗水平逐年上升。研究公共机构节能关键技术的应用，是提高建筑能效、减少能源浪费的有效途径。本研究以公共机构关键节能技术的绩效为研究对象。结合不同节能技术特点和相关国家标准，从综合能效、经济性、环保性和运行管理四个方面选取评价指标。根据专家调研结果和实测数据，采用人工神经网络和专家评分法确定指标权重，构建了完整的指标评价体系。评价体系中有4个一级评价指标，10个二级评价指标，11个三级评价指标。权重最大的各级评价指标分别为建筑综合能效（0.532）、技术能效（0.331）和水泵耗电量与热（冷）传动比（0.167）。公共事业单位关键节能技术评价体系有助于运营管理者发现系统运行的薄弱环节，及时制定优化方案。该评价体系可为提高事业单位节能水平提供有价值的参考。

The COVID-19 pandemic threatened the world. As an important transportation hub connecting countries and regions, airports have played a critical role in COVID-19 prevention and control. This study developed an infection risk-human comfort-energy consumption model to calculate the COVID-19 transmission and energy consumption for epidemic prevention and control in seven different functional areas of an airport during different seasons (winter, summer, and transition season) and actual passenger movement. When considering dynamic passenger flow, the energy consumption needed to prevent and control transmission of the epidemic in each area of the airport could be reduced by 71–85 %. The waiting, dining, and shopping areas were the areas with the highest energy consumption, accounting for 25–47 %, 15–32 %, and 11–38 % of the total energy consumption of epidemic prevention at the airport, respectively. The dining area had the highest energy consumption per square meter, reaching 14.2 kWh/m² at its highest. After closing the dining area, energy consumption was reduced by 14–20 %. Compared with strict epidemic prevention and control, energy consumption in the airport was reduced by 70–85 % considering both optimized intervention and dynamic passenger flow. The results of this study provide a scientific basis for energy-saving and emission reduction in airports under an epidemic situation.

新冠肺炎疫情威胁全球。机场作为连接国家和地区的重要交通枢纽，在疫情防控中发挥了重要作用。本研究建立了感染风险-人体舒适度-能耗模型，计算了某机场不同季节（冬、夏、过渡季节）和实际客流量在7个不同功能区的COVID-19传播和疫情防控能耗。在考虑动态客流的情况下，机场各区域防控疫情传播所需能耗可降低71 - 85%。候机区、用餐区和购物区是机场防疫能耗最高的区域，分别占机场防疫总能耗的25 - 47%、15 - 32%和11 - 38%。用餐区每平方米能耗最高，最高时达到14.2 kWh/m2。关闭用餐区后，能耗降低了14 - 20%。与严格的疫情防控相比，综合考虑优化干预和动态客流，机场能耗降低70 - 85%。研究结果为疫情下机场节能减排提供了科学依据。

The implementation of energy economics principles (EEPs) in sustainable construction and environmental mitigation is widely acknowledged. However, limited research has focused on the hindrances faced in implementing these principles in the context of developing countries. To address this research gap, this study examines these hindrances from the perspective of professionals in the Nigerian construction industry. Existing hindrances were extracted from extant studies using a systematic literature review with predefined inclusion/exclusion criteria which helped formulate the questionnaire. Through the application of exploratory factor analysis, five clusters of hindrance factors were identified, encompassing financial constraints, inadequate policies and regulations, insufficient technological infrastructure, lack of awareness and education and stakeholder-related challenges. Furthermore, the multinomial regression analysis confirmed that the hindrances related to financial constraints, inadequate policies and regulations and insufficient technological infrastructure are the most significant barriers. This study advances scientific knowledge on the hindrances to the adoption of EEPs in Nigerian building projects, providing a comprehensive understanding of the challenges faced in the context of the Nigerian construction industry. Findings from the study will inform policymakers, industry professionals and other stakeholders about the key challenges that require attention and intervention, facilitating the development of targeted strategies and initiatives to overcome these barriers effectively.

能源经济原则（EEPs）在可持续建筑和环境缓解中的应用得到了广泛认可。然而，有限的研究集中于在发展中国家实施这些原则所面临的障碍。为了解决这一研究差距，本研究从尼日利亚建筑行业专业人士的角度考察了这些障碍。通过系统的文献综述，从现有研究中提取存在的障碍，并采用预定义的纳入/排除标准，帮助制定问卷。通过探索性因素分析，确定了五类阻碍因素，包括资金限制、政策法规不足、技术基础设施不足、缺乏意识和教育以及与利益相关者相关的挑战。此外，多项回归分析证实，与财政限制、政策和条例不足以及技术基础设施不足有关的障碍是最重要的障碍。本研究推进了在尼日利亚建筑项目中采用EEPs的障碍的科学知识，提供了对尼日利亚建筑行业背景下面临的挑战的全面理解。研究结果将使决策者、行业专业人士和其他利益相关者了解需要关注和干预的关键挑战，促进制定有针对性的战略和举措，以有效克服这些障碍。

Cold storage technology is useful to alleviate the mismatch between the cold energy demand and supply. The integration of cold energy storage in cooling system is an effective approach to improve the system reliability and performance. This review provides an overview and recent advances of the cold thermal energy storage (CTES) in refrigeration cooling systems and discusses the operation control for system optimization. Firstly, the composition and principles of cooling systems coupled with CTES are presented. Special attention was paid to cold storage medium of phase change material (PCM) with high energy density and stable phase change temperature. Then, based on the classification of driven energy, the different applications of passive or active cooling systems with CTES are classified, including building cooling, cold chain logistics, and other refrigeration systems. Most importantly, the operation control which is necessary to performance optimization is presented, including operational control strategies, cold load predictions, and economic evaluation methods. Three types of operational control strategies are summarised using water storage and cooling system as an example. Two types of cold load predictions, parametric regression and artificial neural network method, are introduced. Three aspects of economic costs are summarized in terms of initial equipment investment cost, operational cost, and life-cycle cost are summarized. Finally, an outlook on the development of cooling systems using CTES is given.

Abandoned mines are rich in geothermal resources. In this article, the feasibility of applying a water resource heating system in abandoned mines is explored, adopting mine water in the extraction zone as the research object. First, the utilization mode of geothermal resources in abandoned mines is introduced, and the applicable scenarios of different mine water heating methods are clarified. Second, to prevent the heat transfixion phenomenon caused by an irrational arrangement of pumping wells, a three-dimensional numerical calculation model for multiphysical field coupling of the pumping wells of a water source heat pump in abandoned mines is established, and 14 distinct types of well arrangements are simulated. According to the occurrence degree of heat transfixion, the most reasonable arrangement of pumping wells is selected. The influences of different recharge temperatures, pumping and recharging flow rates, well spacings, hydraulic gradients, aquifer thicknesses, porosities and other factors on the pumping temperature are studied according to the selected pumping and recharging well arrangement scheme. Finally, by choosing a residential building as the analysis object, a simulation model of the abandoned mine water source heat pump heating system is constructed, which is compared with a gas boiler heating system, revealing the energy savings and environmental protection benefits of the abandoned mine water source heat pump system. The results of this paper provide a scientific basis for the utilization of mine water geothermal resources, which can facilitate the transformation of abandoned mines and provide theoretical and technical guidance in engineering practice.
