Special Issue Information

Dear Colleagues,

This Special Issue of Buildings aims to publish a collection of articles focused on energy-efficient, low-carbon and energy-flexible buildings. We welcome papers presenting new research results and proven practices aimed at reducing the energy needs of a building and improving indoor environment quality, as well as those considerably advancing building science. Special attention will be given to practical and experimental research articles reporting significant innovations. Articles reporting advances in theoretical and simulation methods are welcome once results are fully validated using appropriate experimental data, as well as those reporting application of numerical or theoretical methods for the analysis of new technology and materials and innovative designs.

Additionally, this Special Issue is also focused on innovative, cutting-edge technologies and knowledge, all rigorously verified with measurement and analysis. Buildings publishes articles related to the environmental performance of the built environment in a wide range of spatial scales, ranging from cities, communities and buildings to building systems and assemblies as well as other built environments, such as those related to transportation and industrial settings. We encourage submissions of collaborative, multidisciplinary research results with broader significance.

With the deepening of aerogel research and the popularization of its application, the demands for energy saving in the construction field has brought aerogels into the limelight. To explore state-of-the-art research and development trends related to aerogels applied in construction, CiteSpace was used to conduct a quantitative analysis based on the Web of Science core database. Results show that: (1) in the past 10 years, the number of papers on aerogels in the field of constructions has increased significantly; (2) the top producing countries in the aerogel field are mainly China and the United States, and the top two research institutions are all Chinese institutions (Univ Sci & Technol China and Chinese Acad Sci); (3) the main publishing journals are ENERGY AND BUILDINGS, CONSTRUCTION AND BUILDING MATERIALS, and CHEMICAL ENGINEERING JOURNAL; (4) the hot keywords are thermal insulation, silica aerogel, thermal conductivity, phase change material, mechanical property, graphene aerogel, self-assembly, energy saving, etc.; (5) aerogel is mostly used in building insulation, mainly in the form of aerogel glass, aerogel mortar, aerogel felt, and aerogel coating. In summary, in addition to systematically strengthening theoretical research, it is necessary to optimize the technical process and reduce costs in order to effectively promote aerogels in construction energy conservation and carbon reduction. Through this study, the current situation, hot spots, and development trend of aerogel application in construction can be revealed systematically. Overall, this study helps advance research on aerogels applied in buildings and help in tackling energy efficiency challenges. Full article

This paper investigates the effect of porous-media arrangement, hot-plate arrangement, heat flux, and inlet flow on the mixed convection heat transfer, and uniformity of temperature and concentration in an open enclosure. This model is considered for use as an adsorption treatment unit for radioactive waste gas in a nuclear medicine building. The radioactive waste gas flows through the cavity from bottom to top. The two-dimensional governing equations have been solved using the finite volume method. The Prandtl number and aspect ratio of the cavity are fixed at 0.71 and 1, respectively. The problem has been governed by five parameters: −10 ≤ Br ≤ 10, 10−6 ≤ Da ≤ 102, 0.1 ≤ Kc ≤ 10, 10−2 ≤ Ri ≤ 10, and 0.1 ≤ Kr ≤ 10, and the layouts of the porous layer and hot plates. The simulation results indicate that the Type C (polymeric porous media) has excellent heat transfer characteristics with a 10% increase in the Nusselt number (Nu). The contours of streamlines, isotherms and heatlines indicate that, with the increase of Richardson number (Ri), the trend of Nu varies for different arrangements of hot plates. It is interesting to note that the convective heat transfer of Type F (surrounded arrangement) was found to have the lowest Nu number for the same Ri number. The convective heat transfer is more pronounced for Type E (symmetrical arrangement). The Nu number of Type E (symmetrical arrangement) is about 110% higher than that of Type F (surrounded arrangement) and it is about 35% higher than that of Type D (centralized arrangement). This type also has a more uniform temperature distribution, as indicated by the temperature variance. The findings of this study can guide preheating system optimization. Full article
