摘要:

People’s social behavior, especially environmental behavior, has a great impact on energy consumption and carbon emission. This paper explores both categories of individual factors (e.g., values, habits, education, motivation, etc.) and social factors (e.g., institution, infrastructure, encouragement, etc.), to clarify the correlation between them and their sub-factors. Low-carbon campus is a representative type of low-carbon community which is less difficult to build than other communities because university students are well-educated and, to some extent, are more environmental aware and more willing to change their behaviors. The energy-saving and environment-friendly policies implemented on campus are collected and overviewed in this paper. Additionally, the leaders and employees from the related administration departments are interviewed, and the data of electricity amount and water usage are analyzed and a well-designed questionnaire is handed out in a survey. The survey investigates the environmental knowledge, energy use habits, attitude toward low-carbon transformation, comments on the current institution and so on. The results show that different groups of students have varied levels of environmental knowledge, energy use habits, and attitude toward low-carbon campus management. To improve energy conservation and cut carbon emission radically, advices on building low-carbon community are also proposed including professional curriculums of environmental protection, economic initiatives, effect management, good communications, and sound infrastructures and facilities.

摘要: The energy consumption of campus buildings has specific characteristics, because of the concentrated distribution of people’s working time and locations that change in line with distinct seasonal features. The traditional energy system design and operation for campus buildings is only based on the constant room temperature, such as 25°C in summer and 18°C in winter in China, not taking into consideration the real heating or cooling load characteristics of campus buildings with different functions during the whole day and whole year, which usually results in a lot of energy waste. This paper proposes to set different set-point temperatures in different operation stages of public and residential campus buildings to reduce the heating and cooling design load for energy station and total campus energy consumption for annual operation. Taking a campus under construction in Tianjin, China as an example, two kinds of single building models were established as the typical public building and residential building models on the campus. Besides, the models were simulated at both set-point room temperature and constant room temperature respectively. The comparison of the simulation results showed that the single building energy saving method of the peak load clipping could be used for further analysis of the annual energy consumption of campus building groups. The results proved that the strategy of set-point temperature optimization could efficiently reduce the design load and energy consumption of campus building groups.

Continuous amino-functionalized University of Oslo 66 membranes as efficacious polysulfide barriers for

《化学科学与工程前沿(英文)》 2023年 第17卷 第2期   页码 194-205 doi: 10.1007/s11705-022-2206-7

摘要: The shuttle effect of soluble polysulfides is a serious problem impeding the development of lithium−sulfur batteries. Herein, continuous amino-functionalized University of Oslo 66 membranes supported on carbon nanotube films are proposed as ion-permselective interlayers that overcome these issues and show outstanding suppression of the polysulfide shuttle effect. The proposed membrane material has appropriately sized pores, and can act as ionic sieves and serve as barriers to polysulfides transport while allowing the passage of lithium ions during electrochemical cycles, thereby validly preventing the shuttling of polysulfides. Moreover, a fast catalytic conversion of polysulfides is also achieved with the as-developed interlayer. Therefore, lithium−sulfur batteries with this interlayer show a desirable initial capacity of 999.21 mAh·g–1 at 1 C and a durable cyclic stability with a decay rate of only 0.04% per cycle over 300 cycles. Moreover, a high area capacity of 4.82 mAh·cm–2 is also obtained even under increased sulfur loading (5.12 mg·cm–2) and a lean-electrolyte condition (E/S = 4.8 μL·mg–1).

摘要:

Buildings are known to significantly affect the global carbon emissions throughout their life cycle. To mitigate carbon emissions, investigation of the current performance of buildings with regard to energy consumption and carbon emissions is necessary. This paper presents a process-based life cycle assessment methodology for assessing carbon emissions of buildings, using a multi-storey reinforced concrete building in a Sri Lankan university as a case study. The entire cradle-to-grave building life cycle was assessed and the life span of the building was assumed as 50 years. The results provide evidence of the significance of operation and material production stages, which contributed to the total carbon emissions by 63.22% and 31.59% respectively. Between them, the main structural materials, concrete and reinforcement steel made up 61.91% of the total carbon emitted at the material production stage. The life cycle carbon emissions of the building were found to be 31.81 kg·m2 CO2 per year, which is comparable with the values obtained in similar studies found in the literature. In minimizing the life cycle carbon emissions, the importance of identifying control measures for both building operation and material production at the early design stage were emphasized. Although the other life cycle stages only contributed to about 5.19% of the life cycle carbon emissions, they should also receive attention when formulating control strategies. Some of the recommended strategies are introducing energy efficiency measures in building design and operation, using renewable energy for building operation and manufacturing of materials, identifying designs that can save mass material quantities, using alternative materials that are locally available in Sri Lanka and implementing material reuse and recycling. This study is one of the first to undertake a life cycle carbon emissions assessment for a building in the Sri Lankan context, with the hope of facilitating environmentally-friendly buildings and promoting sustainable construction practices in the country.

摘要: has been applied to a variety of applications such as video surveillance, traffic monitoring, assembly control, and other public safety applications. Context information, such as perspective distortion and background interference, is a crucial factor in achieving high performance for . While traditional methods focus merely on solving one specific factor, we aggregate sufficient context information into the network to tackle these problems simultaneously in this study. We build a fully convolutional network with two tasks, i.e., main density map estimation and auxiliary . The main task is to extract the multi-scale and spatial context information to learn the density map. The auxiliary task gives a comprehensive view of the background and foreground information, and the extracted information is finally incorporated into the main task by late fusion. We demonstrate that our network has better accuracy of estimation and higher robustness on three challenging datasets compared with state-of-the-art methods.

摘要: In about 1949, there was a large-scale migration of architects from the mainland to Hong Kong, China. Among them were those important figures in the modern Chinese architectural history such as Robert Fan, Su Gin-Djih, and Chu Pin. Their arrival at this colony had changed its architectural practice substantially from professional organization to actually built environment. Their unique contributions to Hong Kong’s modern architecture have been a new research interest in recent years. This paper tells a story about Robert Fan and his design of the Chung Chi College campus in the 1950s with an intention to reveal the multiaspects of the so called “migrant architects” through a single architectural event. The author tries to capture the intertwining relationship between the migrant architects and educators through the reconstruction of the recruitment process for a campus architect by Chung Chi College and to identify Mr. Robert Fan’s concept of campus planning with reference to his early design experience in the mainland of China.

摘要: The key parameters that may influence building energy performance is studied by comparing the building energy data of college buildings in two different regions (the USA and China). By introducing data-orientated approach, a study of a set of on-campus building energy demand and consumption is conducted for cooling, heating and electricity. In addition, the heating, ventilation and air conditioning (HVAC) and lighting systems are studied in great detail. The breakdown analyses of the current energy consumption data are used to focus the investigation on critical issues. The analysis shows that the energy consumption of college buildings in the USA can be 3–5 times more than that of college buildings in China. The over-high energy consumption in campus buildings in the USA is mainly caused by operation schedule, system style, cooling and heating counteraction and sensor/actuator faults in the control systems, which also leads to the discussion of energy difference on the concept of “full control” or “local improvement” in building environment control. The study also indicates that the building energy efficiency can only be achieved by adjusting the demand according to natural conditions, encouraging green life behaviors, and developing relative technical solutions coordinated with the thrift culture and human behavior.

摘要: Building a rainwater system based on the idea of low-impact development (LID) is an important aspect of the current “sponge city” construction in China. The “sponge city” concept emphasizes that the runoff can permeate the soil or be stored temporarily, and rainwater could be used again when it is needed. Beijing is one of the earliest cities to study rainwater harvesting and LID techniques in China. Through long-term monitoring of rainfall, runoff flow, and water quality of a campus demonstration project in Beijing, the runoff quantity and pollutant concentration variations have been analyzed. Furthermore, the runoff reduction effects of single LID measure, such as green roof, filtration chamber, and permeable pavement, have been investigated. Additionally, the overall reduction effectiveness of the LID system on the average annual rainfall runoff and pollution load has been discussed. Preliminary studies suggest that runoff pollutant concentration is positively correlated with the rainfall interval time, and the longer rainfall interval time leads to higher runoff pollutant concentrations. The very good outflow quality of the rainwater harvesting system could satisfy the reclaimed water quality standard for scenic entertainment use. The non-point-source pollution reduction effects of the LID system are obvious because the pollutants could be removed by filtration on the one hand and the pollution load could be reduced because of the significantly reduced outflow on the other hand.
