Results show the following： （1） In smaller buildings （〈 5,000 m2）, setting temperatures are higher in summer and lower in winter, effects of ＂uncomfortable radiation from windows＂ are greater, energy-saving systems decrease indoor thermal comfort, but claims of ＂hot＂ and ＂cold＂ are fewer; （2） Claims of ＂hot＂ and ＂cold＂ are unrelated to the setting temperature and whether the air-conditioning control system is central or local; （3） The adoption rates of mitigation of dress codes （＂COOL-BIZ＂ and ＂WARM-BIZ＂） are higher than those of temperature mitigation of air conditioning.展开更多

For electrical automation engineering, the application and promotion of energy saving and environmental protection technology can reduce the waste of resources and solve the problem of power resource shortage to a certain extent. Therefore, the relevant departments need to constantly improve the energy-saving design technology in electrical automation engineering to make it play a full role in the electrical field.展开更多

According to relevant data, China's building energy consumption has remained high for many years, accounting for more than 30% of the total social energy consumption. In civil engineering, the construction of buildings is the most important content. At present, China's urbanization construction is further accelerated, and there are more and more civil engineering projects with larger and larger scale, which also means that the problem of energy consumption of civil engineering buildings will be more and more serious. Therefore, it is of great practical significance to strengthen the research on energy-saving measures of civil engineering buildings.展开更多

In recent years, China has been studying energy-saving methods and measures. Therefore, we should analyze the development of energy-saving technology in building electrical design, and put forward specific measures to develop energy-saving technology, so as to improve the overall energy-saving effect of building electrical design in our country.展开更多

At present, the public's demand for basic goods is increasing, which affects the increasingly complex electrical design of civil buildings. The designer should design the electrical system of the building according to the actual situation of the building to ensure the quality of the electrical system, save energy and reduce emissions as much as possible. However, the design of energy-saving systems is also influenced by many other factors, and the delay of their design. With the progress of science and technology, the safety, reliability and economy of energy-saving civil electrical equipment design are greatly improved.展开更多

In order to improve the quality of indoor environment, HVAC system has become an indispensable part of building system. But at the same time, the energy consumption of HVAC system also accounts for 50~60% of the total energy consumption of buildings, and it is a major contributor to the total energy consumption of buildings. Therefore, it is of great significance to carry out research on energy-saving technology of HVAC system and improve energy efficiency for achieving the goal of "double carbon". Based on this, this paper takes the urgency and importance of the application of energy-saving measures of HVAC system as the starting point, expounds the energy-saving design principles of building HVAC system, and puts forward some main energy-saving measures of HVAC system for reference.展开更多

The investigation results showed that the average intensity of energy consumption in office buildings in Tianjin accounts for 161.51 kW-h/（mZ.a）. By breaking the energy consumption down into detailed items, it was found that the heating system consumed the highest amount of energy （46.6%）, followed by equipment （35.9%）, cooling system （11%） and lighting system （6.69%）. The main factors for office building energy consumption were found and some feasible measures to save energy were proposed.展开更多
