摘要 ：
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.

摘要 ：
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.

摘要 ：
Steam is used to provide heating and moisture in the curing process for the production of precast concrete (PC) construction elements. The generation of steam requires large amounts of fossil fuels. This study considers the incorporation of solar thermal energy into the steam curing of PC construction elements for reducing the need for fossil fuels and associated CO2 emissions. For this purpose, the board made of composite phase change material covers the inner surface of the main sun-facing wall in the heating & curing building. The PCM board is heated by sun rays and accumulates thermal energy during the PCM's phase transition, and this energy then is released to the indoor environment of the building, reducing the amount of steam required to maintain a certain level of temperature during the curing process. The energy consumption simulation software, EnergyPlus, and two physical models (built on the scale of 1:3) were used to study the effects of two different PCMs on the thermal performance of such new type of heating & curing buildings. Composite PCMs considered were GH-33 and GH-37 with 33 and 37 degrees C melting temperatures developed by the research team. The theoretical and experimental results are in good agreement and demonstrate that, compared to the GH-33, GH-37 PCM increases the temperature of the inner surface of the main sun-facing wall and the upper surface temperature of the PC construction element by 3.4 and 1.4 degrees C, respectively. The heat accumulation and discharge rates also were greater by 62%. For the investigated design of the building and given location in China, the deployment of studied PCM wall panels results in a reduction in the annual energy consumption and CO2 emissions by 58.6 GJ and 5 tons, respectively. The method developed for applying solar energy and selecting PCMs for augmenting steam curing of PC construction elements can be deployed in different geographical regions.

摘要 ：
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.

摘要 ：
Air filters are one effective way of removing indoor fine particulate matter (generally known as PM2.5). An accurate evaluation of indoor PM2.5 filtration load will provide great help in designing efficient air filtration systems. In order to make the existing indoor PM2.5 filtration load calculation model more available by considering the availability of some important parameters, such as air infiltration volume through a unit length of external window (ql), particle penetration factor (P), and deposition rate (k), this study introduces a determination method of those key design parameters for various external window airtightness levels under infiltration conditions. Furthermore, the indoor PM2.5 filtration loads were quantified based on a longitudinal field measurement from five unoccupied offices located in the central area of Beijing, China. Results revealed that higher airtightness level windows can help to significantly decrease the indoor PM2.5 filtration load. The proposed method in this study can help in the calculation of indoor PM2.5 filtration load through infiltration and the design of indoor air filtration systems. © 2020, Springer Nature Singapore Pte Ltd.
