Abstract ：
The secondary solar heat gain, defined as the heat flows from glazing to indoor environment through longwave radiation and convection, grows with the increasing of glazing absorption. With the rapid development and application of spectrally selective glazing, the secondary solar heat gain becomes the main way of glazing heat transfer and biggest proportion, and indicates it should not be simplified calculated conventionally. Therefore, a dynamic secondary solar heat gain model is developed with electrochromic glazing system in this study, taking into account with three key aspects, namely, optical model, heat transfer model, and outdoor radiation spectrum. Compared with the traditional K-Sc model, this new model is verified by on-site experimental measurements with dynamic outdoor spectrum and temperature. The verification results show that the root mean square errors of the interior and exterior glass surface temperature are 3.25 degrees C and 3.33 degrees C, respectively, and the relative error is less than 10.37%. The root mean square error of the secondary heat gain is 13.15 W/m(2), and the dynamic maximum relative error is only 13.2%. The simulated and measured results have a good agreement. In addition, the new model is further extended to reveal the variation characteristics of secondary solar heat gain under different application conditions (including orientations, locations, EC film thicknesses and weather conditions). In summary, based on the outdoor spectrum and window spectral characteristics, the new model can accurately calculate the increasing secondary solar heat gain in real time, caused by spectrally selective windows, and will provide a computational basis for the evaluation and development of spectrally selective glazing materials.

Abstract ：
Fine description for regional solar spectra has always been critical for improving solar energy utilization. However, it is difficult and complex to implement due to large amount and high-dimensional characteristics of the measured solar spectra. To address the above challenges, this study proposed a data-driven method to describe regional solar spectra using 211,877 global horizontal irradiance spectra in Beijing area as case data. Firstly, the dimensions of each measured spectrum were reduced from 2,221 to six using the deep autoencoder. Then, all dimensionality-reduced measured spectra were categorized into five clusters using the agglomerative hierarchical clustering. The clustering results exhibited notable variations across different months and dates. Finally, the local reference spectra were determined based on clustering results, and their effects on the performance of typical photovoltaic materials were analyzed. The maximum mismatch factor for typical photovoltaic materials under local reference spectra can reach up to 21 %. The comparisons with standard spectrum highlighted that the superior capacity of local reference spectra to describe the configuration of regional solar energy. This study provides a novel insight into the fine description for regional solar spectra, which sets a new direction for innovation in photovoltaic technology and promotes the sustainable utilization of renewable energy.

Abstract ：
Light meets the visual needs of the human body through the visual channel, and guides the physiological system of the human body to synchronize with the cycle of luminous environment through the non-visual channel, affecting emotions, sleep quality, alertness and even health. The indoor luminous environment of buildings where people spend more and more time is divided into two parts: artificial lighting and daylighting, both of which are separated from each other in terms of standards and research. However, integrated lighting scenes where daylight and artificial light exist at the same time are very common in real-life indoor environments, and the relationship between the two in integrated lighting and the impact of integrated lighting on non-visual effects remain unclear. In this study, the amount of daylight was manipulated by controlling sunshades in different artificial lighting environments, and the relationship between daylight and artificial light in integrated lighting was explored based on the subject evaluations. The results show that the direction and shading form have a significant impact on the perception of daylight, and the front facing direction has its particularity because it directly receives daylight. Additionally, artificial lighting settings with varying illuminance and correlated color temperature can also affect the perception of daylight. Furthermore, compared to artificial lighting alone, integrated lighting in sunny conditions can significantly increase circadian stimulus, which could improve daytime work efficiency.

Abstract ：
The luminous environment is an essential factor that affects people's working and living experiences in buildings. In order to clarify the building luminous environment parameters that are required for occupant satisfaction, we collected 2553 completed questionnaires while conducting field measurements of new and updated luminous comfort metrics in 15 contexts in four cities in China. By developing a five-step approach to identifying the luminous environment needs of different building occupants, including data cleaning, correlation analysis, and nonparametric testing, we determined the thresholds for all key metrics for each scenario. The research results show that different public building environments have unique luminous environment improvement requirements, and this conclusion can guide future lighting design, LED technology and daylighting integration technology.

Abstract ：
The falling film flow characteristics of a liquid on the surface of corrugated sheet packing are crucial for its mass transfer performance in various industrial applications. In this study, a falling film flow experiment with laser-induced fluorescence technology was conducted to validate the flow characteristics of a falling film simulated using computational fluid dynamics (CFD). The influences of Reynolds number (Re) and the packing structure on flow characteristics were analyzed with quantitative film thickness and wetted area obtained through three-dimensional simulation. The results show that the CFD model can accurately predict the liquid falling-film flow behavior and calculate the characteristic parameters. For sinusoidal corrugated sheets, when Re reaches 500, the groove flow changes into a rivulet flow along the adjacent ripples and the wetted area is at its largest, about 0.022 m(2). However, relative to the geometric area of the corrugated sheet, the wetted area can only reach 20% of the surface area, and the overall wetting performance is still poor. Triangular and trapezoidal corrugated sheets were further proposed and proved to improve the wetting area compared with the sinusoidal sheet, with maximum increases of 23% and 9%, respectively. On this basis, extensive research was carried out on the corrugation angle. The results show that a triangular corrugated sheet with a 75 degrees corrugated angle was more conducive to the flow of the liquid film, and the wetted area was 38.8% of the surface area.

Abstract ：
Thermochromic (TC) window has been developed as an effective approach to realize building energy saving by regulating solar transmittance according to temperature stimuli; however, the non-uniform transmission and absorption of the solar spectrum result in a significant color shift and temperature increase. This study investigates the radiometric, photometric and colorimetric performances of four different TC windows with an experiment-verified model. The simulation and calculation are conducted under measured spectrum conditions in Beijing; subsequently, a comprehensive evaluation method for daylight-thermal environment method is conducted. The results show that all selected TC windows possess an energy efficiency between 3.0% and 7.9%, improve daylight availability from 2.8% to 18.8%, and reduce discomfort hours by up to 111 h. Two hydrogel TC windows improve the quality of dynamic transmitted daylight by nearly 7% considering correlated color temperature and color rendering index; the HETS hydrogel TC window is found to be the most suitable for Beijing. Finally, to increase the application potential of TC windows in Beijing, several material properties are desired, including high transition temperature with high solar modulation capability, high and uniform visible light transmittance, and low emissivity. This process for the optimization of climate-responsive material can be further adopted in other areas. © 2022 Elsevier Ltd

Abstract ：
The use of wet scrubbing to remove airborne molecular contaminants in cleanroom make-up air units has economic benefits and good application prospects. Still, problems with this method include low removal efficiency and large water consumption. To improve scrubbing performance, we built a full-scale scrubbing experiment platform using SO2 as the removal object. In addition, we applied structured packing in the scrubbing process to enhance the mass transfer between gas and liquid, and we tested the wet scrubbing removal efficiency and pressure drop under a variety of operating conditions. Results showed that under the condition of double -row spraying only, the SO2 removal efficiency increased with increasing liquid-gas ratio. The efficiency ranged from 57% to 83.9% and the pressure drop ranged from 6 to 15 Pa. After adding structured packing, the removal efficiency under different liquid-gas ratios improved significantly. Improvement was more apparent, ranging from 72.2% to 86.2%, when the liquid-gas ratio was low. The pressure drop also increased, ranging between 59 Pa and 100 Pa. In addition, we changed the packing thickness and the number of stages, and found that when the packing thickness was 0.2 m and the two-stage spacing was 0.15 m, removal efficiency improved up to 89.7%. The research results are significant for optimizing wet scrubbing performance and, at the same time, have practical engineering value for controlling the concentration of airborne molecular contaminants in the cleanrooms.

Abstract ：
Background: Coronavirus disease 2019 (COVID-19) is primarily a respiratory disease that has become a global pandemic. Close contact plays an important role in infection spread, while fomite may also be a possible transmission route. Research during the COVID-19 pandemic has identified long-range airborne transmission as one of the important transmission routes although lack solid evidence. Methods: We examined video data related to a restaurant associated COVID-19 outbreak in Guangzhou. We observed more than 40,000 surface touches and 13,00 0 episodes of close contacts in the restaurant during the entire lunch duration. These data allowed us to analyse infection risk via both the fomite and close contact routes. Results: There is no significant correlation between the infection risk via both fomite and close contact routes among those who were not family members of the index case. We can thus rule out virus transmission via fomite contact and interpersonal close contact routes in the Guangzhou restaurant outbreak. The absence of a fomite route agrees with the COVID-19 literature. Conclusions: These results provide indirect evidence for the long-range airborne route dominating SARSCoV-2 transmission in the restaurant. We note that the restaurant was poorly ventilated, allowing for increasing airborne SARS-CoV-2 concentration. (C) 2021 The British Infection Association. Published by Elsevier Ltd.
