Based on the geological conditions of cut and cover tunnel of the South to North Water Transfer Project, lining temperature field for crack control is simulated by finite element software-ANSYS. Through simulation of hydration heat effects, large temperature difference areas can be identified quantitatively, thermal insulation and sprinkler maintenance can be carried on during the initial setting...
In arid and semi-arid areas, the diurnal and annual temperature ranges are large. Taking reasonable measures of thermal insulation, the indoor thermal environment can be comfort. The traditional dwellings, in arid and semi-arid areas of western China, have energy efficient characteristic, among which Yaodong is the typical representative. In this paper, the temperature in Yaodong wall will be tested...
Building energy consumption is tremendous in China. The energy consumption of building envelope walls is 4- 5 times higher compared with that of developed countries. The envelope walls built by solid clay brick and other masonry materials have a poor thermal insulation performance, and can not meet the requirements of building energy efficiency. This paper investigates the thermal performance in winter...
The situations of low story dwelling in northeast rural areas of China was introduced, aggregate comparing analysis was carried out on thermal insulating performance of dwellings with different structure, building material and thermal insulating equipment. According to construction experience of rural thermal insulating and ecotypical dwellings, a new rural dwelling was provided here. The new light-weight...
Typical residential earth buildings in Southern Hunan area are of civil engineering structure, namely, adobe walls, wooden doors and windows, wooden roof truss covered by blue tiles. In this paper, the author made a field mapping and energy consumption survey on a typical residential building in Southern Hunan area, and conducted an indoor test on heat and humidity index in summer and winter. The...
Space heating accounts for the greatest energy consumption in cold regions of China. Proper application of thermal insulation is one of the most effective energy conservation measures for residential buildings. Therefore, determining and selecting the optimum thickness of insulation is important not only for the environment but also for the energy costs. In this paper, a mathematical model demonstrating...
External thermal insulation system (ETIS) is an important part of building energy efficiency. Polyurethane foam as a superior external insulation material was analyzed in this paper. The variation law of bond strength of the ETIS with polyurethane foam was studied by atmospheric exposure tests which consist of two stages including high temperature-spraying water cycle and heating-refrigeration cycle...
The building thermal insulation is an important technology of building energy efficiency. Taking the typical residential in the cold region-Beijing and those of South China-Guangzhou as the template, this paper has conducted simulation analysis on their respective energy consumption when adopt exterior thermal insulation walls or interior thermal insulation walls. The study has shown that the exterior...
Mineral wool is among the commonly used conductive insulation material for building insulation. Studies on insulated building envelope in temperate climate have shown potential energy savings towards attaining energy efficient buildings and sustainable built environment. To date, there is no empirical data on the benefits of insulated building envelope in warm humid tropical climate. Such data would...
In order to research energy-saving transform of public building, six the large and medium-scale emporiums in Handan were selected as object. On the basis of investigation into typical department emporium, set an elementary model of emporium building, made out the four different transform program to improve heat preservation of exterior wall, such as used double-layer window and added heat insulation...
