Thermal Simulation Analysis of Insulation of the New Heat-Insulation Bricks

Using the ANSYS thermal analysis module to do steady thermal analysis of given heat-insulating bricks. The results show that this kind of bricks can achieve better insulation in both sides; when the thermal conductivity of the heat insulating material in the hole space are less than 0.3 W/(m·K), the bricks can obtain the good insulation effect; the smaller the heat conductivity coefficients of the bricks materials and filling materials are, the better insulation bricks can achieve.

Thermal Simulation Analysis of Pass Design of the Heat-Insulating Bricks

The pass design, hole rates and materials affect the insulation properties of perforated bricks directly. In order to study their effects on the insulation of the perforated bricks, six models was analyzed by the thermal module of ANSYS. The results prove that larger quadrate holes rates lead to better insulation, and the material with small thermal conductivities contribute to large heat transfer resistance value of the bricks. To achieve the energy saving standards, more bricks with lower coefficient of thermal conductivity are to be developed.

With the ideality of sustainable development, this paper summarizes the meaning, principles and characteristics of the evaluation green university index system by probing into the research about the present construction of green university and related field. The system is based on a tree-like structure that consists respectively of the overall goal and multilevel indices. The thesis put forward an index system for assessment of green university, which contains five aspects (the green concept, the green culture, the green research, the green education, the green campus). Afterwards, the weightiness of index is determined by the way of AHP, and the method of the multi-hierarchy comprehensive evaluation system is applied to evaluate the universitys green degree.

Numerical Simulation Analysis of Hole Shape Design of Self-Thermal Insulation Perforated Brick

The hole shape design of perforated brick directly affects thermal insulation performance of wall. In order to study the influence of shape, size and configuration of perforated brick on the insulation performance, six kinds of perforated brick with different hole shape were designed, and their temperature field were simulated with finite element method. The results show that the insulation performance of perforated brick with square hole is the best. Filling brick holes with thermal insulation materials can improve the insulation performance of perforated brick, Besides; The thermal conductivity of perforated brick affects its thermal resistance, so brick materials with low thermal conductivity should be developed for the achievement of energy-saving standard of wall thermal resistance.

Based on the concept of sustainable development, this paper focus on the study of evaluation index system of green university. The model of the assessment index system of green university was created based on Analysis Hierarchy Process. The Fuzzy Comprehensive Evaluation (FCE) was used for post project evaluation on Jiangnan University. The results show that Jiangnan University meets the criteria of green university, and the corresponding improvement suggestions were put forward aiming at its disadvantages.

The Evaluation of Green University Based on Analysis Hierarchy Process

This paper gives the model of assessment index system to evaluate the process of green university based on Analysis Hierarchy Process. Based on sustainable development strategy, and according to the principles and the theoretical foundation of evaluation index system, the assessment index system was constructed from running a school with green ideas, constructing green culture, encouraging green scientific research, implementing green education, and building green campus. The weight vectors of the indexes were determined by Analysis Hierarchy Process. The model is beneficial to the evaluation and establishment of green university.

Green University Star Rating Evaluation Based on the Multi-Level Grey Approach

In the view of the construction of green university throughout the world, this paper summarizes the principles, connotation and methods of the evaluation green university index system. An index system is established for assessment of green university, which contains the green concept, the green culture, the green research, the green education and the green campus. By applying the multi-level grey approach, the article tries to innovate the evaluation approach of green university and develop Green Star rating system. Taken Jiangnan university as a case study, a comprehensive evaluation model is employed to puts forward a feasible and useful way for green university evaluation.

Green Campus Culture Construction of Green University

Green campus culture is a new type of campus culture, emphasizing the relationship between people and the environment is coordinated sustainable, profound and abundant. Green campus is an important aspect of the green university, an important way of promoting sustainable development and achieving the comprehensive development. Green culture construction should be carried on from several aspects: management, education, environment, activities and internationalization, etc, so as to give full play to its educational function.

Technical and Economic Analysis on Self-Insulation Schemes of 65 Percent Energy Efficiency for Residential Buildings in Hot Summer and Cold Winter Zone

With the further promotion to the energy conservation of buildings, the standard of 65 percent energy efficiency is gradually popularized. Because of some existing problems in external insulation Technology, such as security, durability and seepage, Self-insulation technique has been more and more concerned. In this paper, a kind of external insulation scheme and three kinds of Self-insulation schemes are designed for a typical residential building in Wuxi region. These schemes are simulated for energy consumption calculation and Economic Analysis by BECS software. The results show that self-insulation schemes not only meet the standard of 65 Percent Energy Efficiency, but also have more economic benefits than external insulation schemes.

Analysis on the Effect of Shape Coefficient to Energy Saving in Residential Buildings

Building shape coefficient is an important factor in building energy saving design. In order to analyze the influence of shape coefficient to the energy consumption, a typical residential building is simulated by BECS software to analyze the changing regular patterns of the energy consumption for heating and air conditioning while the building shape coefficient is made different. The relationship between building height and shape coefficient, and the impact of the building plane layout on the energy consumption are also analyzed. The results show that the reduction of shape coefficient is benefit to enhance the effect of energy saving.
