Abstract
With the rapid development of global civil engineering construction, the intelligent structural system of civil engineering has evolved into one of the current global frontier disciplines. The research on the intelligent structural system of civil engineering and the current development situation are analyzed, and the main problems are combined. Giving reasonable suggestions is of great significance to the country's vigorous development of civil engineering intelligent structure system. This paper designs a new type of three-dimensional fiber grating sensor, including the design of the matrix model and the design of fiber grating strain gauges. This new sensor can effectively measure three-dimensional space, greatly expanding the application range of fiber grating sensors. In this paper, the design lighting area of each light pipe is taken as a unit. Each unit is set with 4 measuring points at the center and the edge. Each measuring point reads 3 illuminance value parameters and records the average value. Based on the results and comprehensive consideration of the short board situation, the research conclusions and recommendations are put forward. The foundation wall with aerated concrete blocks as the wall material can meet the requirements of 50% energy saving for exterior wall buildings with external decoration and internal insulation mortar. Compared with the benchmark wall of 50% energy saving of external wall buildings, the heat transfer coefficient is reduced by 50.1%, and the actual energy-saving effect of the wall can reach 75%. Meet the requirements of 65% for the energy-saving effect of exterior wall buildings. This paper considers economic parameters, such as the investment cost of building insulation materials, energy-saving income, and investment recovery period, and establishes a calculation model for analyzing the economics of insulation materials. Based on the heat transfer model of the composite wall and the fuel energy combustion equation, greenhouse gas is an established calculation model for CO2 and SO2 emissions. Studies have shown that when considering the room temperature insulation performance of insulation materials, the time required for the side of the concrete slab with glass fiber felt and aerogel insulation materials is about 2022 and 3363 s, respectively, indicating the fire resistance of aerogel insulation materials significantly better than fiberglass.
Highlights
With the rapid development of the social economy and the continuous improvement of people’s quality of life, energy consumption has gradually increased [1], of which building energy consumption accounts for about 40% of the total energy consumption of the whole society, so building energy saving is the key to achieving energy saving in the whole society field
Compared with the benchmark wall of 50% energy saving of exterior wall buildings, the heat transfer coefficient is reduced by 50.1% when the exterior decoration stickers are applied and the phase change mortar is applied inside. e actual energy-saving effect of the wall can reach 75%. e requirement of wall building energy-saving effect is 65%
When the phase change mortar is applied on both the inside and the outside, the heat transfer coefficient is reduced by 29.85% compared with the benchmark wall of 50% energy saving of the external wall building, and the actual energysaving effect of the wall can reach 65%, meeting the energy saving of external wall building 65% effect requirement
Summary
With the rapid development of the social economy and the continuous improvement of people’s quality of life, energy consumption has gradually increased [1], of which building energy consumption accounts for about 40% of the total energy consumption of the whole society, so building energy saving is the key to achieving energy saving in the whole society field. On the premise of meeting the requirements of building use and the quality of the indoor thermal environment, reduce the energy consumption of equipment cooling and heating, lighting, hot water supply system, and so forth; use energy reasonably and efficiently; and realize the overall energy saving of the building. Chowdhury and Dey. Advances in Civil Engineering produced the aerogel mortar by experiment and applied it to the structural wall in the French region. Using the outdoor weather data of the typical weather year as the external weather conditions, the numerical value of the energy-saving potential of phase change materials in residential buildings was simulated [5]. E heat transfer coefficient of the composite wall is tested by the variable temperature method to investigate the phase change energy storage, energy-saving effect of composite wall. The evaluation data of each case is analyzed and compared with the evaluation standard, and the conclusion of evaluation and analysis of lighting application effect is obtained
