The importance of building energy efficiency to civil engineering?

What is the specific content of the importance of building energy efficiency to civil engineering? Here, Zhong Da Consulting will answer your questions.

As we all know, energy is non-renewable. How to reduce energy waste while developing is a very important and thorny issue. In this regard, all walks of life in China have begun to pay attention to energy conservation, emission reduction and low-carbon environmental protection. With the development of economy, people's ideology has also been improved. Most people's ideas are no longer limited to advocating luxury and wealth, and more and more people attach importance to the low-carbon lifestyle of energy conservation and environmental protection. For the houses where people live daily, it is necessary to meet the requirements of energy conservation. On the basis of paying attention to building quality in civil engineering, building energy efficiency has also attracted people's attention, which also puts forward higher requirements for building construction units. Building energy saving in civil engineering is of inestimable importance, and the author of this paper will focus on this issue.

1 summary of energy saving in civil engineering buildings

1. 1 Analyze the current situation of building energy consumption in China. Nowadays, the construction field in civil engineering has been called the three major energy-consuming industries in China together with transportation and industry. Especially in the field of architecture, stimulated by China's economic development and the improvement of residents' living standards, the field of architecture in China's civil engineering has developed rapidly, and buildings have mushroomed. At present, the total area of housing construction in China is about 44 1 100 million square meters. On this basis, the annual increase in housing area/kloc-0.8 billion square meters is not comparable to the total area of all developed countries. But for many buildings at present, only 1% can be regarded as energy-saving buildings, and most of them are high-energy-consuming buildings, whether from the external structure of the building or from the heating equipment. Most new buildings are also high energy-consuming buildings. In recent years, due to the huge energy consumption, we have also realized the importance of energy conservation. China has given great encouragement and support to building energy conservation. Many regions have also formulated relevant acceptance standards and inspection standards for building energy conservation construction technology, and formulated policy standards for promoting and promoting energy conservation and environmental protection in the construction field in civil engineering. Energy-saving buildings are also developing slowly. However, compared with most developed countries, the starting point of building energy conservation in China is low, the time is late, and the number base of high-energy buildings is also large, so energy conservation, environmental protection and low-carbon development in the field of civil engineering construction are still very important.

1.2 Necessity analysis of energy saving in civil engineering buildings. Due to the new requirements of energy conservation and environmental protection, the concept of energy conservation has also begun to sprout in the field of architecture. In the process of gradual development, China's civil engineering has made certain achievements in the field of energy conservation. For some problems and defects that still exist at present, many regions in China have formulated relevant industry standards and energy-saving guidelines, which not only require high building quality, but also have higher requirements for energy saving, objectively urging and encouraging construction units to continuously improve the level of building energy saving. At present, with the gradual acceleration of industrialization, the level of urbanization is also constantly improving, and the total amount of construction in China is on the rise. However, due to the large consumption of energy and resources in the process of industrialization, the current energy is very tight. Reducing energy use in the construction field is an important means to effectively alleviate energy shortage, so it is of great significance to start implementing building energy conservation and emission reduction in civil engineering. In the traditional construction industry, a lot of energy is consumed, such as air conditioning, heating and other equipment used in the construction industry, as well as lighting facilities and hot water supply systems used in daily life. These facilities are high-consumption products, which is very unfavorable for energy saving. Among many energy-consuming facilities, air conditioning and heating equipment consume a lot of energy, accounting for more than half of all energy consumption. In practice, due to the poor quality of building insulation materials and the low thermal efficiency of heating equipment in China, the energy consumption of heating facilities in China is more than three times that of countries with the same climate conditions under the same area. In some areas of China where the temperature is very low, the energy consumption of buildings in urban areas can sometimes exceed 50% of the total local energy consumption. However, in many areas in China where summer is relatively hot, because there are no relatively concentrated large-scale heating facilities in winter, they will choose to use electrical equipment for heating in winter and air conditioning for cooling in summer. In this case, buildings will consume more power resources. In the face of energy shortage and serious environmental pollution, it is very important for the construction industry to take effective measures to save energy and reduce emissions, and it is necessary to solve the problem of energy waste in civil engineering in time.

2. Explore specific measures for energy conservation in the construction field.

2. 1 Discuss the basic principles that should be observed in building energy-saving construction. In order to ensure real energy conservation and environmental protection in the field of civil engineering construction, certain principles must be followed. First of all, we should follow the principle of respecting nature and selecting sites scientifically. In view of China's vast land area and huge differences in topography, climate and environment in different regions, in order to strengthen building energy-saving measures in civil engineering, it is necessary to conduct necessary investigation and analysis on local natural environment, topography and soil hydrology according to building site selection, and select appropriate building materials and facilities on the basis of fully respecting local natural culture and customs, so as to reduce energy consumption and waste. Another principle to be followed is to design the external environment of the building scientifically to ensure economic security. In practice, after the building site selection is completed, the surrounding environment will be comprehensively and reasonably built to a certain extent. For example, planting green belts around buildings can not only improve air quality, but also effectively reduce noisy noise without affecting normal indoor lighting. Moreover, urban greening landscapes such as streams and even rockeries can be built near houses, which seems to beautify the environment, but it can actually help regulate the climate to a certain extent. Hot summer helps to reduce the indoor temperature of buildings. At the same time, the frequency of air conditioning will be relatively reduced, and finally the purpose of energy saving and emission reduction will be achieved.

2.2 Establish and improve the management mechanism of building energy efficiency. Establishing and perfecting the management mechanism of building energy conservation is the main means to strengthen building energy conservation. However, the actual situation in practice is that the management and supervision mechanism of building energy efficiency in China is not perfect, the law enforcement is not enough, the legislation is lacking, and the investment in new technologies of building energy efficiency is not enough, which leads to no obvious progress in the field of building energy efficiency in China. Therefore, it is an important topic to promote the energy-saving management system in the construction industry, which is helpful to promote the smooth development of the building energy-saving industry. Therefore, the author suggests that relevant departments strengthen law enforcement, standardize the construction behavior of construction units, and improve the relevant laws and regulations system. It is very important to ensure energy conservation in the construction industry from two aspects: legislative mitigation and effective supervision.

2.3 Adhere to efforts to innovate and develop energy-saving technologies. The fundamental of energy saving lies in the progress and innovation of energy saving technology. In practice, using high-performance building materials and equipment, improving the utilization efficiency of resources, selecting building materials with high durability and strength, innovating new energy-saving technologies, and adding new technologies such as sound insulation and waterproof to building materials will make great contributions to energy conservation in the building field.

Concluding remarks

Building energy saving in civil engineering is of great practical significance to our daily life. Due to the current energy shortage, energy conservation in the construction industry will reduce atmospheric pollution and waste of resources, and will play a positive role in the harmonious coexistence of the whole human society and the environment. Moreover, the energy-saving of civil engineering buildings should meet people's pursuit of quality of life and improve people's living standards. Therefore, the author makes a necessary analysis of the current situation of China's construction industry and the waste of resources, and puts forward relevant measures in order to make necessary theoretical contributions to energy conservation and environmental protection in the construction field in practice.
