Authors: Sun Bin , Guo Zixi , Zhang Yi , Zhen Huaibin , Zhang Shuling , Zeng Qinggang 
Published: September 2019

Abstract
The fracture conductivity is one of the most important factors affecting coalbed methane production. The size of proppant, the number of proppant placement layers and the embedment all affect the permeability, thus affecting the fracture conductivity. However, exist research ignored the influence of fracture width. Therefore, according to the formula for calculating the fracture width of acid fracturing, the formula for calculating the fracture width is deduced. According to Carman-Kozeny formula, the fracture conductivity calculation models with and without embedment are respectively established. Through conducting the flow experiment on the coal core, the influence of the number of placement layers and embedment degree on the fracture conductivity is analyzed. The results show that the larger the particle size of proppant is, the more layers are laid, and the wider the fracture width is, thus the greater the fracture conductivity is. The smaller the embedment degree of proppant, the greater the fracture conductivity.

Acoustics Tomography Simulation for Probing Oil Reservoir
Authors: Shen Yedi , Ma Zhongli 
Published: September 2019

Abstract
In oil exploration, the acoustic wave is usually generated by the hammer stroke method and then propagates to the interior of the formation. Finally, the information of oil reservoirs is obtained by inverting the reflected compressional waves. In order to make full use of the echoes, we use the reflected shear wave to inverse the compressional wave velocity and compare it with the actual measured compressional wave velocity to serve as a quicklook oil detection. COMSOL Multiphysics, based on the finite element analysis, is used to simulate the propagation process of ultrasonic waves in the physical model, which is different from the previous simulation methods. Moreover, it can provide data for other imaging algorithms quickly.

Authors: Lu Yufeng , Su Yi , Liang Zhaoting , Lu Yifan 
Published: September 2019

Abstract
In order to study the influence of the test current on the dynamic resistance measurement of the SF6 circuit breaker with different erosion degrees, simulated erosion experiment was carried on 126 kV SF6 circuit breaker. The result shows, that the higher the test current is, the smaller the resistance of arcing contact when the circuit breaker is of any degree of erosion, but there is always no obvious link between the arcing contact travel and the test current. In addition, the dispersion of the test results decreases with the increase of the test current. However, when the erosion of the circuit breaker is very serious, the dispersion of results will be great regardless of the value of the test current. Therefore, considering the influence of test current on contact resistance, in order to obtain actualarcing contact resistance and to reduce the dispersion of test results considering the influence of test current on contact resistance, the larger dynamic resistance test current should be chosen as much as possible, and the dynamic resistance test must be carried on many times when contact erosion is extremely serious, so that the state of arcing contact can be obtained according to the distribution of test results.

Authors: Wang Tao , Liu Dan , Dong Jing 
Published: September 2019

Abstract
An open-shell polyoxopalladate(II), TBA-Na-SrPd12(pent)3 (TBA = [(n-C4H9)4N]+, pent = [C5H9O2]-), was used as catalyst in the hydration of aromatic nitrile for the first time, because such structure exhibits ligand exchange ability. TBA-Na-SrPd12(pent)3 has been proven to be active for a series of substrates and interestingly the yield (22% ∼ 98%) is significantly influenced by the steric hindrance of aromatic nitriles. Furthermore, this polyoxopalladate can promote the hydration of benzonitrile under solvent-free conditions giving the yield of 99%.

Energy Flexible Buildings - The impact of building design on energy flexibility
Authors: Weiß T 
Published: September 2019

Abstract
Thermal load management has substantial theoretical potential for energy flexibility. To use the inherent flexibility in buildings, for example, district heating companies could temporarily control the heating system of buildings to switch-off or preheat dwellings in the morning to avoid using peak load gas boilers. The »thermal flexibility« in this study indicates the tolerance of buildings towards the changes of its heating system operation according to an external signal. The focus of this investigation is to give an overview of »thermal flexibility« of residential buildings in Austria from 1920 – 2020 with different envelope qualities, construction types and heating systems. Existing residential buildings in Austria usually have a high thermal mass within their massive brick or concrete primary structure, and therefore their indoor thermal conditions react slowly to operative changes in the supply of thermal energy. Depending on the buildings ability to retain or store heat inside the building envelope, space heating can be used to offer energy flexibility. Among other factors, especially the quality of the thermal envelope, the thermal capacity of the building, the sluggishness of the heat delivery system and passive solar gains are crucial for keeping indoor thermal comfort. Dynamic building simulation in IDA ICE is used to evaluate the potential of selected building typologies to shift heating loads away from peak demand periods. Potentials of various building archetypes according to the EU-Tabula building database to time-shift the operation of the heating system are pointed out respecting occupants’ comfort.
Dynamic Benchmarking of Building Strategies for a Circular Economy
Authors: Eberhardt L , Birgisdottir H , Birkved M 
Published: September 2019

Abstract
Increasing building demands from a growing world population puts enormous pressure on natural resources. Management of resource consumption and environmental impacts is therefore vital to secure contemporary and future well-being and progress. Circular Economy (CE) is perceived as an industrial economy model potentially minimizing resource consumption, waste production and environmental impacts by the means of increased material circularity e.g. reuse. In order to promote CE in buildings, there is a need for benchmarks to support building designers in choosing environmentally viable solutions. Although life cycle assessment (LCA) help policy makers and building practitioners to define such benchmarks, benchmark studies often rely on static LCA approaches. Hence, uncertain and unknown dynamic changes during a buildings’ long service life influencing the performance of long term sustainable building design principles are not accounted for. Through a literature review the paper at hand identified dynamic technological progress such as resource and energy consumption, energy grid mix, waste management, design and innovation and production efficiency as potentially essential to include when defining realistic CE building strategy benchmarks. How these dynamic factors may affect LCA results were demonstrated through a case study of a concrete column based on a range of possible scenarios. This included estimated future projections and the uncertainty relating to prospective assessments resulting in an output in the form of a span of possible future developments and environmental impacts instead of a single output. Based on the literature review and case study, main challenges of incorporating dynamism within building LCA benchmarking were identified.

Authors: Verellen E , Allacker K 
Published: September 2019

Abstract
The current renovation rate in Belgium is less than 1% and should be increased to 2, 5% to reach the European targets to reduce the GHG emissions by 2050. There is a need to rapidly increase the renovation rate and at the same time guarantee that these renovations reduce the environmental impact on our planet. In order to define environmental benchmarks for existing buildings and their renovation targets, a better understanding of the existing building stock is needed. In this paper, the approach used to model the existing building stock is presented for the specific case of Leuven. The methodological steps, challenges and data gaps are presented in detail. The proposed building stock model uses GIS data in order to gain insights in the geospatial distribution of the impacts of the stock. These spatial maps moreover allow to clearly visualise the impacts which can improve communication and contribute to policy actions.
Impact of dynamic CO2 emission factors for the public electricity supply on the life-cycle assessment of energy efficient residential buildings
Authors: Müller A , Wörner P 
Published: September 2019

Abstract
Climate change and its effects are the reasons for the energy transition in Germany and lead to an increasing exploitation of renewable energy sources. At the same time, energy efficient buildings reduce the heat demand significantly and allow for the operation of electricity based heating systems. With the aid of dynamic CO2 emission factors, the life-cycle assessment (LCA) for buildings can be adapted to reflect the fluctuating nature of renewable energy sources and the dynamics of heating power demand during the use phase more precisely. A case study using dynamic building simulation and static as well as dynamic emission factors for the year 2017 shows deviations of 3.4 % in the building’s GHG emissions. Furthermore, two emission factors for 2030 and 2050, which reflect the national 80 % carbon dioxide reduction target, are developed and applied to the case study. For these emission factors, the overall building’s GHG emissions decline drastically, whereas the deviation between the LCA using static or dynamic emission factors increases significantly. It can be seen that the application of a more dynamic approach for LCA adds substantial value to the investigation. However, further investigation on a broader set of dynamic input parameters for the LCA of energy efficient buildings seems to be reasonable.
