Quantifying environmental characteristics on psychophysiological restorative benefits of campus window views

In recent years, the physical and mental health of college students has received increasing attention. Campus window views have the potential to help college students quickly relieve psychological stress in their studies and daily lives. In the current study, we measured psychological and physiological changes in 42 participants to evaluate 15 campus window views at Shenyang Jianzhu University. The Short Version Revised Restoration Scale and two physiological measures (heart rate variability and skin conductance level) were combined with quantitative environmental characteristic indicators to analyze the impact of window views’ environmental characteristics on restorative benefits. The results revealed the following: (1) Environmental characteristic indicators were significantly correlated with psychological and physiological indicators, but they were not in a monotonic functional relationship. (2) The restorative benefits were greatest under the following conditions: 1.53 ≤ fractal dimension ≤1.57, 0.80 ≤ naturalness index ≤0.88, 0.48 ≤ green view index ≤0.51, 0.78 ≤ dominant color system proportion ≤0.82. When the quantity of the color system was 1, the restorative benefit was relatively low. This study provides insights into the thresholds for the impact of campus window view environmental indicators on stress recovery, and extends the theoretical basis of research on window views.

Study on fresh air load characteristics and energy saving measures of low energy consumption buildings in severe cold area

In order to study the fresh air load characteristics of low energy consumption buildings with different envelope structure parameters, combined with the law of fresh air load, energy saving measures were studied. Taking the ultra-low energy consumption building of Shenyang Jianzhu University as an example, the DeST simulation software was used to establish five groups of models with different envelope structure parameters for load simulation. The simulation results show that the fresh air heat load in model 1 to model 5 is 29.89%, 34.66%, 38.60%, 44.68% and 53.36% of the building heat load, respectively. The seasonal fresh air cooling load of air conditioning accounted for 13.78%, 13.85%, 13.88%, 13.99% and 14.05% of the building cooling load respectively. The thermal insulation performance of the envelope has great influence on the thermal load of the building, but little influence on the cooling load of the building. The better the insulation performance of building envelope, the greater the energy saving potential of fresh air load. Fresh air heat load is sensible heat load, and fresh air cooling load is mainly latent cooling load. From the theoretical point of view, the building adopts a heat recovery device with a heat recovery efficiency of 0.6, which can save 5989.91kW • h in the heating season and reduce the building heat load by 32.02%. In the air conditioning season sensible heat recovery device can save energy 131.45kW • h, reduce building cooling load by 1.56%; Total heat recovery device can save energy of 708.73kW • h and reduce cooling load of building by 8.43%.With the development of zero-energy building technology, the requirement of fresh air energy consumption is more strict, and the active all-heat fresh air heat recovery device is more suitable for this building. It also has more space for future development. This paper analyzes the change of energy saving potential of fresh air with the development of building envelope. The methods and ideas of reducing energy consumption of fresh air in low energy consumption buildings are discussed.

Building 3D Realistic Modeling Based on Air-ground Multi-source Data Fusion

Three-dimensional point cloud data is a new form of three-dimensional collection, which not only contains the geometric topology information of the object, but also has high simplicity and flexibility. In this paper, the air-ground multi-source data fusion technology is used to study the fine reconstruction of the 3D scene: based on the 3D laser scanning laser point cloud, the 3D spatial information of the ground visible objects is obtained, and the orthophoto obtained by the drone aerial photography is assisted, Obtain the three-dimensional space information of the top of the ground feature, and the ground three-dimensional laser scanner can quickly obtain the three-dimensional surface information of the building facade, ground, and trees. Due to the complex structure of the building and the occlusion of spatial objects, sub-station scanning is required when acquiring point cloud data. This article uses the Sino-German Energy Conservation Center Building of Shenyang Jianzhu University as the research area, using drone tilt photography technology and ground lidar technology to integrate. During the experiment, the field industry adopted the UAV image acquisition strategy of “automatic shooting of regular routes, supplemented by manual shooting of areas of interest”; in the field industry, the method of “manual coarse registration and ICP algorithm fine registration” The example results show that the ground 3D laser point cloud air-ground image fusion 3D modeling effect proposed in this paper is better and the quality is greatly improved, which makes up for the ground 3D laser scanning. In point cloud modeling, a large number of holes are insufficient due to occlusion and missing top information.

High-pressure-induced phase transition in cinchomeronic acid polycrystalline form-I**Project supported by the National Natural Science Foundation of China (Grant Nos. 11604224, 51805336, and 11774120), the Open Project of State Key Laboratory of Superhard Materials of Jilin University, China (Grant No. 201708), the Natural Science Foundation of Liaoning Province, China (Grant No. 20180550861), the Education Department of Liaoning Province, China (Grant Nos.

Diamond anvil cells combined with Raman spectroscopy and angle-dispersive x-ray diffraction (ADXRD) were used to investigate the compression behavior of cinchomeronic acid (C7H5NO4, CA), a hydrogen-bonded polymorphs. The compression of form-I at approximately 6.5 GPa caused an irreversible phase transition that produced the new polymorph form-III. Lattice and internal modes in the Raman spectra were analyzed to determine the modifications in the local environment of CA form-I molecules. The form-III was indexed and refined to a low-symmetry triclinic structure with space group P1. The mechanism for the phase transition involved the reconstructions in the hydrogen-bonded networks in CA form-I.

Research on the Construction of BIM Visualization Model Based on 3D Laser Point Cloud Data

The point cloud data of the main structure obtained by three-dimensional laser scanning technology is used as the basic data of the 3D modeling, and the point cloud data are processed by point cloud splicing, point cloud registration and point cloud de-noising. Taking the China-German energy saving demonstration center of Shenyang Jianzhu University as the research object, the "family" model of the building is established in the BIM modeling software Revit by the size of the point cloud data size, and then the BIM 3D model of the building is established so as to record and manage the building information on the building components. The experimental results show that the point cloud data obtained by 3D laser scanning has realized precise modeling and precise modeling in the process of building 3D model of building. Based on the idea of BIM, a three-dimensional model is established through the point cloud data. The model has accurate coordinate data, which provides the basis for the combination of BIM and GIS.

Low-carbon building design and practice in severe cold areas

With a vast territory and seven climate zones, China’s urbanization is constantly improving while building energy conservation and emission reduction are facing severe challenges, especially in severe cold areas. In China’s Liaoning Province, urban public buildings and rural residential buildings consume huge amounts of energy. According to the characteristics of Liaoning, “passive technology advanced, active technology second” is the best choice for energy saving and emission reduction. Taking Sino-German Energy Conservation Demonstration Center in Shenyang Jianzhu University as an example in this paper, through analysis of the operation monitoring data of energy consumption, the objective is to provide a good reference method and a design strategy for the near zero energy buildings in the severe cold areas and to verify its feasibility. At the same time, the parametric design technique is applied to feature-based design system, such as multi objective optimization and genetic algorithm combined simulation technology, Rhino Grasshopper Energy plus energy saving technology and cost-benefit analysis model to obtain the optimal solution. It provides innovative technology demonstration for building energy conservation in the severe cold areas.

3rd China-Romania Science and Technology Seminar (CRSTS 2018)

FOREWORDAfter the establishment of the People’s Republic of China, Romania was among the first countries in the world to have developed diplomatic relations with China (October 5th, 1949) and, in the following decades, the political, economic and cultural relations between the two countries have continuously evolved, being based on friendship, confidence and reciprocal support. Thousands of cooperation projects in almost all sectors of industry, agriculture, education, science, culture etc. were implemented for the benefit of China and Romania. Whilst the post-1989 changes in the Romanian society partially affected the intensity of this fruitful cooperation, more and more Romanian decision-makers and representatives of the business sector, the academia, as well as of the scientific and cultural life have recently understood that reviving the cooperation with China should be a priority. And not only because of the tremendous economic and technological development of China nowadays, but also because of the long-lasting friendship and trust between the two countries.In recent years, Transilvania University of Brasov has been at the forefront of the academic and scientific cooperation between Romania and China. The establishment of the Confucius Institute in 2012, in partnership with Shenyang Jianzhu University, represented the impulse for a new stage of intensive cooperation between the two universities and also between the two countries. Hundreds of staff and student mobility exchanges, the participation in scientific events in China and Romania, the establishment of new cooperation partnerships in Beijing, Tianjin, Hunan province etc., the establishment of a Chinese language Bachelor’s study programme, the implementation of an international joint laboratory project and a “111” project, and the active involvement in the “16+1 cooperation” in the field of forestry and education are only a few examples of this excellent cooperation in recent years. Our university is fully committed to the further development of the academic and scientific cooperation between Romania and China, and we are convinced that the approaching of the 70th anniversary of the People’s Republic of China and 100 years of modern Romania, will represent the beginning of a new stage of intensive cooperation between the two countries for the benefit of our peoples.List of committees are available in this pdf.

Research and Application of Distributed Energy Integration Optimization for Sino-German Building in the Cold Area of China

With the global energy demand growth, caused by excessive energy consumption and environmental pollution is increasingly serious. And the building energy consumption accounts for about 40% of the global total energy consumption, with great potential for energy saving. Especially in the cold area of northeast China, the summer is very hot and the winter is long and cold. And extreme weather often occurs,the hot and cold polarization is serious. So china cold area need a stable way of energy supply, In the long run, DES systems are an essential part. DES system as a system that can be distributed on the user terminals and supplies energy, is more durable and less prone to massive power outages than a power grid system. To a large extent, it improves the fragility of traditional grid system, avoids the phenomenon of large-scale power outage and solves the problem of long-distance transmission loss.The author mainly describes the application of DES system in the severe cold area of China. Taking the of Shenyang Jianzhu University as an example, the author introduces the DES system including dual-source heat pump unit. This DES system involves a variety of energy forms and energy conversion devices. By promoting the use of low-texergyerature energy of the solar and air or ground, not only low-quality heat needs are met, but also high-quality energy is saved and the overall energy efficiency is improved. The author mainly analyzes the representative winter and summer seasons of Shenyang Jianzhu University Sino-German building, and the energy supply method using distributed energy system is compared with the conventional energy supply method using only the grid.And the Pareto function is introduced which including the best possible trade-offs between the economic and exergy inputs objectives, is obtained by minimizing a weighted sum of the total energy cost and total primary exergy input using branch-and-cut. The results show that energy costs can be significantly reduced through optimized operation of distributed energy systems compared to conventional energy supply systems that use grid-only power supply, and can significantly improve the overall effective energy efficiency to achieve energy saving and emission reduction.

The quality of luminous environment of man-machine systems

Illuminations of libraries influence readers learning efficiency, emotion, eyesight and health. Here, we apply the principles of the light distribution curves and make rational use of natural lighting and artificial lighting integrating the buildings' function and form, to create a pleasant light environment. We use measurement data analysis and calculation of illumination combined with ergonomics principles, to evaluate the illumination and glare on the Shenyang Jianzhu University library. For long-span libraries, on the premise of obtaining natural lighting through a good orientation, indirect daylight through the atrium can make up for the shortage of side lighting and play a complementary role in indoor illumination to a maximum depth of about 5 m. We provide new data to make optical quality better, to make man-machine systems achieve congruency, and to create comfortable and efficient learning environments for readers.

Risk Perception on Nuclear Energy Safety among Chinese University Students

Pseudo-dynamic test and numerical simulation of high-strength concrete frame structure reinforced with high-strength rebars

This paper describes an investigation of a high-strength concrete frame reinforced with high-strength rebars that was tested in the structure engineering laboratory at Shenyang Jianzhu University. The frame specimen was pseudodynamically loaded to indicate three earthquake ground motions of different hazard levels, after which the test specimen was subjected to a pseudo-static loading. This paper focuses on the design, construction and experiment of the test frame and validation of the simulation models. Research shows that a high-strength concrete frame reinforced with high-strength rebars is more efficient and economical than a traditional reinforced concrete frame structure. In addition to the economies achieved by effective use of materials, research shows that the frame can provide enough strength to exceed conventional reinforced concrete frames and provide acceptable ductility. The test study provides evidence to validate the performance of a high-strength concrete frame designed according to current seismic code provisions. Based on previous test research, a nonlinear FEM analysis is completed by using OpenSees software. The dynamic responses of the frame structure are numerically analyzed. The results of the numerical simulation show that the model can calculate the seismic responses of the frame by OpenSees. At the same time, the test provides additional opportunities to validate the performance of the simulation models.
