Electric Energy Saving Technology In Foshan Public Culture Complex

Energy conservation has become a general consensus of society.Reasonable energy conservation and improvement of energy efficiency will be important factors in the sustainable development of society.Statistical analysis of relevant data shows that,China's building energy consumption,of which electrical energy consumption is in the dominant position,accounts for about 32% of the total energy consumption of the whole society,so vigorously energy-saving and environmentally friendly green building is imperative.It is very important to adopt electric energy-saving technology in green building.The technology of electric energy-saving contains a lot of information,including not only the energy saving of power supply and distribution systems,energy saving of electrical lighting,energy saving of building electrical equipment(elevators,fans,pumps,transformers,etc.),but also the utilization of renewable energy such as solar power system,building energy efficiency management system,building automation systems and other management tools,so the study of building of electrical energy-saving technologies is of great significance to the study of whole building energy conservation.This paper,through a research of a large number of literature and engineering practice experience,on the basis of the summarization of current measures or techniques commonly used in energy-saving building,combined with the Foshan Public Cultural Complex(Youth Palace,Science and Technology Museum)project,gives us a detailed analysis and discussion of three kinds of electrical energy-saving technologies in this project,including:(1)Solar power system: the configuration of the main electrical equipment,the system's grid connection mode,the system's power distribution design,the lightning protection design,and the calculation of the number of PV modules connected in series and parallel.The configuration of grid-PV module electrical properties and other issues.(2)Lighting and control system: Energy saving can be saved from the source by using high-efficiency and energy-saving light sources,lamps and accessories under the requirements of satisfying illumination,color rendering,evenness and starting time;To achieve scientific and automatic centralized management,reducing operating and management costs while achieving the best energy-saving effect.(3)Energy efficiency management system: Briefly introduce the topological structure of the energy efficiency management system,collect statistics on the energy use of each energy point,and regularly provide energy consumption data for each measurement point to facilitate the classification and analysis of building energy consumption.Combining with the historical data,meteorological conditions and other factor analysis The rationality of the data makes it easy for managers to find the best combination of energy saving and comfort in the operation and use of buildings,reduce operating costs and increase economic benefits.
