“…For instance, university buildings in the USA account for about 13% of the total building energy consumption, with teaching buildings being key drivers of this due to their schedules and occupancy densities [10]. Similarly, in China, Liu and Ren reported that colleges and universities use 8% of the total energy consumed by Chinese society [11]. They also mentioned that university students consume four times more energy than the average Chinese citizen.…”

In this paper, the energy performance of a university campus in a tropical climate is assessed, and four mixed classroom buildings are compared using benchmarking methods based on simple normalization: the classic Energy Use Intensity (EUI), end-used based EUI, and people-based EUI. To estimate the energy consumption of the case studies, building energy simulations were carried out in EnergyPlus using custom inputs. The analysis found that buildings with more classroom spaces presented higher energy consumption for cooling and lighting than others. In comparison, buildings with a greater percentage of laboratories and offices exhibited higher energy consumption for plug loads. Nevertheless, differences were identified when using the people-based EUI since buildings with larger floor areas showed the highest values, highlighting the impact of occupant behavior on energy consumption. Given the fact that little is known about a benchmark range for university campuses and academic buildings in hot and humid climates, this paper also provides a comparison against the EUIs reported in the literature for both cases. In this sense, the identified range for campuses was 49–367 kWh/m2/year, while for academic buildings, the range was 47–628 kWh/m2/year. Overall, the findings of this study could contribute to identifying better-targeted energy efficiency strategies for the studied buildings in the future by assessing their performance under different indicators and drawing a benchmark to compare similar buildings in hot and humid climates.

“…As a result, the Green performance study is carried out here based on the overall layout forms of dormitory buildings. The layout designs of table 5 coincides with one of a paper published by the author [13], but with the addition of diagonal layout and optimized integrated layout of long and short staged, the overall layout types are more diverse, which can fully explain which layout form is more suitable for the objective of environmental liveability. It can be seen from Tab.…”

Background: Green BIM emphasizing the contribution of BIM technology to the design and construction of green buildings. It attaching importance to the impact of climate and regional environment, using benchmarking and target setting, using BIM architecture for building performance analysis and realizing performance optimization through scheme comparison and modification. A university campus is a community that has a certain geographical scope and spatial scale and involves a variety of functions, such as teaching, scientific research, and living space. Hence, a campus possesses urban characteristics and diverse building types, and the construction of green university campuses will play a leading role in green urban construction in China under the increasing ecological and energy pressure of cities. Methods: Based on the Green BIM decision cycle model, the study employs BIM architecture to analyses building performance. By using the as the evaluation benchmark values and project objectives and taking the most representative teaching buildings, libraries, and dormitory buildings in universities in northern China as examples, the study selects appropriate BIM software, establishes models in steps, and conducts targeted visual analysis. The purpose is to find out the commonness and difference through the analysis, and then realize that the diversity of building types in campus determines that the green performance research of different types of buildings should comprehensively consider various design factors. Results and conclusions: Taking a university library in northern China as an example, the study optimized it from four aspects: base environment, function layout, envelope performance and system transformation, and management measures improvement. The results show that the total annual cumulative energy consumption load of the scheme is reduced obviously. The conclusions are that the improvement of university buildings' green performance must be comprehensively carried out from the aspects of planning, building design, system design, energy management, and energy conservation planning. In the future, we also need to carry out energy consumption data mining, continue the energy-saving transformation of existing buildings and energy consumption systems, achieve the goal of green and low-carbon campus.

“…The annual energy consumption is nearly 30 million tons of standard coal, and the water consumption is nearly 4 million tons. The total energy consumption accounts for 8% of the total social energy consumption (Liu & Ren, 2020). We found that the university-industry collaboration efficiency is determined by a university's characteristics, scientific research fund from the government, and regional economic status.…”

It is necessary to know the state of the Chinese universities. In this paper the general objective was determine the situation of Chinese universities: Problems, COVID-19 & efforts. Methodology, in this research, 31 documents have been selected, carried out in the period 2016 - 2021; including: scientific articles, review articles and information from websites of recognized organizations. The keywords used in the searches were: Chinese universities and COVID-19. Results, China has approximately 2,845 universities, which are gradually improving their infrastructure and academic level. The percentage of women has increased (UIS.UNESCO, 2021). A close collaboration between the university and the industry was presented as they refer (Hou, Hong & Shi, 2021). Employers consider the University of Hong Kong to have the best graduates (SICAS, 2018). Difficulty deciding what to investigate. The situation in Chinese universities is stabilizing, after COVID-19 was presented, continuing with virtual courses and the intensive use of ICTs. In addition, the progressive opening of these institutions, monitoring the health of students and teachers. Conclusions, Chinese universities are ranking better in world rankings such as the QS World University Rankings. They are overcoming the limitations imposed by COVID-19. The number of graduates, researchers and patents is considerable and competes with the great powers of Europe, Asia and North America. In addition, some of its universities are achieving international recognition and have students from various parts of the world.
