Inspection and Assessment of Energy-Saving Renovation Effect of Existing Residential Buildings, Taking Changfeng Residential District in Taiyuan University of Technology as an Example

Abstract

Taking a Sino-German Cooperation project—a demonstration project for energy-saving renovation of existing residential buildings in Changfeng Residential District of Taiyuan University of Technology—as an example, this paper introduces an energy-saving renovation scheme for this district and analyzes the results of energy efficiency inspection after renovation with an attempt to provide references for energy-saving renovation of existing residential buildings in the northern heating zone.

Recent progress on CO2 separation membranes

“…Zhang 71 synthesized a fluorine-containing polysulfone membrane by polycondensation reaction and compared its performance with that of a commercial polysulfone membrane. It was discovered that the polysulfone membranes containing fluorine had a greater gas permeability coefficient.…”

Building Information Modeling Methods for Post-Earthquake Retrofitting Visualization of Buildings Using Augmented Reality

“…One study [22], for example, proposed a combination of laboratory testing and numerical analysis based on using traditional and modern techniques to improve the durability and structural strength of materials. Traditional retrofitting processes have some problems such as the complexity of the professional systems, the tight construction schedule, the environmental restrictions of the construction site, the high requirements for construction quality and safety management, as well as the complex and changing site conditions [10]. Only relying on 2D drawings and planar training, it is difficult to meet the rapid retrofitting needs of modern post-earthquake buildings.…”

“…However, the lack of data synchronization between BIM and on-site processes is recognized as a primary barrier to BIM implementation [8,9]. Traditional retrofitting construction sites also suffer from gaps in planning and execution, and a lack of interaction between project participants [10]. AR is the preferred method to solve the problems regarding the integration of BIM into construction.…”

First-principles study of the (Cu x Ni1 − x )3Sn precipitations with different structures in Cu–Ni–Sn alloys

“…Young's modulus (E) is the comprehensive index of the B and G, which reflects the material stiffness and an internal property of the material. [30] Poisson's ratio (ν) is used to quantify the stability of the crystal against shear, and the larger the ν, the better the plasticity is. These polycrystalline structural properties are important for determining the mechanical properties of materials and can be calculated by using the Voigt-Reuss-Hill (VRH) approximation [31] from the following formulas:…”
