Abstract ：
The rapid development of photovoltaic technology provides more possibilities for the efficient application of solar energy in buildings. This research proposed a phase change material (PCM) heat storage wall system with a "four-layer" structure. A performance test platform using low voltage DC was built to study the mechanism of electric thermal conversion of the graphene electrothermal film and the heat transfer characteristics of the "four-layer" structure. As shown in the experimental results, under the voltages of 24 V, 32 V and 42 V, (1) with the increase in voltage, the temperature of the electrothermal film increases, while its electrothermal conversion efficiency decreases from 85% to 75%; (2) during the heat storage process, because of its latent heat storage characteristics, the temperature of the PCM wallboard is 3 similar to 5 degrees C lower than that of the cement wallboard, but the effective heat storage increases by 59 similar to 65%; (3) during the heat release process, the effective heat release of the PCM wallboard increases by 41-78%, and the maximum heat storage and release efficiency is 98%; and (4) at 32 V, the PCM can completely change phase. The theoretical calorific value of the electrothermal film is equivalent to the hourly power generation of 1.45 m(2) of photovoltaic modules. The results provide basic data for the integration of photovoltaic and phase change technology and their efficient application in buildings.

Abstract ：
The continuous methane emission from the coal piles is associated with many environmental problems and safety risks, in large storage facility. The methane emission parameters of coal piles and the concentration distribution characteristics of methane, which are the basis of ventilation design, are rarely reported in large storage facilities. In this study, based on the mass-transfer diffusion theory, desorption-concentration gradient method for deter-mining methane emission parameters of coal piles in large facilities is proposed. In this method, firstly, the coal pile methane diffusion coefficient was deduced by conducting the coal particles absorption-desorption experi-ments and the particle-size distribution. Then, combing the diffusion coefficient and methane concentration -gradient on the coal pile surface, the coal pile methane diffusion flux was calculated. Further, when methane diffusion flux was utilized as the source item for CFD calculations, the results were consistent with the onsite measured values, which demonstrated the accuracy of this method. The CFD simulation results show that methane has diffusion characteristics that adhere upward along the slope of the coal pile and converge on the coal ridge. The methane flow reaches the dome upwards, where a higher concentration is formed. Both the coal pile volume and the methane diffusion flux will affect the concentration distribution of methane in large storage facility. For a larger diffusion flux, the explosion limit will be exceeded, and measures need to be taken to eliminate the safety risk. These findings provide principal data and analysis guide for optimized design of ventilation performance in closed industrial building.

Abstract ：
The risks of cross-infection among occupants will be greatly increased by the high occupant densities and mobility inside and outside university classrooms. In order to know the distribution characteristics of culturable bacterial aerosols in such public environments, during normal didactic activities, indoor and outdoor bacterial aerosols were sampled from December 2018 to December 2019 by using Andersen six-stage impactor in 11 university classrooms. The yearly average concentration of outdoor bacterial aerosols was 314 +/- 229 CFU/m(3), and the size mainly distributed within 2.1-4.7 mu m. For unoccupied condition, indoor culturable bacterial aerosols were dominated by outdoors (R-2 = 0.78), the yearly average concentration was 254 +/- 130 CFU/m(3), and the size mainly distributed within 1.1-3.3 mu m. For occupied condition, the yearly average concentration of indoor bacterial aerosols was 494 +/- 263 CFU/m(3), and the size mainly distributed in the range of 1.1-4.7 mu m. With human presence, occupants instead of outdoor air becoming the primary source of indoor culturable bacterial aerosols. The seasonal emission rates of bacterial aerosols resulted from occupants were in the order of summer > autumn > spring > winter, corresponding to 1538 +/- 646, 850 +/- 292, 592 +/- 254, and 388 +/- 219 CFU/person/h. Air temperature, relative humidity, and PM10 mass concentrations were main environmental factors (p < 0.01) to positively influence the concentrations distribution of indoor culturable bacterial aerosols. The results can provide basic data for evaluating the risks of occupants expose to bacterial aerosols and improving indoor microbial air quality in university classrooms.

Abstract ：
Despite the rapid growth in the uptake of renewable energy technologies, the educational profile and the skills gained at University level do not always comply with the practical needs of the organisations working in the field. Furthermore, even though the residential sector has very high potential in curbing its CO2 emissions worldwide thus meeting the challenging goals set out by the international agreements, such reduction has been limited so far. Within this context, the 'Skybelt' project, co-funded by the EU under the framework of the Erasmus + programme aims at enhancing in several Universities of Asia and Europe the engineering skills of students of all level for application of sustainable renewable energy solutions in the built environment. With the target of increasing the employability of graduates and the impact of the project, a survey on the labour market needs for specialists with enhanced knowledge and skills in the topic of the project has been conducted in the related Asian countries. Hence, relevant industries, labour market organisations and other stakeholders have been interviewed and the main results of this analysis is reported in the present paper. As first outcome of this activity, the obtained results have been considered in the selection of the modules to be improved according to a student centred study approach. © The Authors, published by EDP Sciences, 2021.

Abstract ：
Active-passive phase change heat storage technologies have been obtained extensive application to decrease greenhouse's demands for fossil energy during off-seasons. To develop the utilization ratio of solar energy in solar greenhouses during winter, the active-passive ventilation wall with latent heat storage (APVW-L) was introduced and could be integrated into greenhouse's back-wall. However, system design and operation parameters are subjected to numerous factors, including its structure, material performance and outdoor meteorological parameters. To achieve optimization in the energy performance of this system, this study used finite element analysis and lumped parameter analysis to establish coupled energy balance equations of the APVW-L and the air inside vertical air passages, and the cubic spline interpolation was used to calculate the continuous relationship between phase change material's equivalent specific heat capacity and temperature. This modeling method of the APVW-L was accurately validated against the measured data, and then used in the optimization design and operation strategy of the APVW-L in the greenhouses. This study demonstrated that the optimized APVW-L could store 5.36 MJ/(m(2).day) of solar energy in Beijing. Compared to the identical conventional greenhouses, after midnight, the experimental greenhouse having APVW-L increased the back-wall's interior surface temperature by 2.2-3.4 degrees C, and the average indoor air temperature by 0.8-1.4 degrees C. This study provides methods for the APVW-L's optimization design and its operation strategy, even for the rationalization of the near-zero energy consumption of the solar greenhouse during winter.

Abstract ：
Prefabricated concrete (PC) components need to be maintained after pouring to guarantee that concrete can harden well in a certain period. Currently, steam maintaining is one of the commonly adopted methods for this purpose. However, it is a bit costly and consumes a large amount of fossil energy. Based on the characteristics of maintaining process of PC components and the thermal characteristics of GH series phase change materials (PCMs) developed by our team, this paper presents an integrated design principle of passive solar energy and phase change heat experiments. Further, the selecting principle of PCMs on the inner surface of the main sun-facing wall of curing buildings wasput forward. The application results of Hebei province, China showed that, the 50mm-thick GH-37 PCM (temperature range of phase transformation: 37.4-43.5 and phase change enthalpy: 227.5kJ/kg) was suitable for the main sun-facing wall. Compared with GH-33 PCM, GH-37 PCM allowed the inner surface temperature of the main sun-facing wall to increase by 3.4 on average at night, the upper surface temperature of PC components to increase by 1.4, and the heat storage and release rate of PCM wall to increase by 62%. This research suggests a new method for renewable energy utilization and low-carbon based environmental protection in PC component curing process. © 2021, Chemical Industry Press Co., Ltd.
