Energy Saving Technology Analysis And Application Of Lighting Design In Civil Construction

With the development of our national economy and the improvement of people's living standard,the function of modern architecture is more and more abundant and humanized.It is reported that Chinese building energy consumption accounts for 1/3 of the total energy consumption in domestic,and the building energy consumption of China ranks second place of the global energy consumption list.In the era which low-carbon and energy-saving are highly promoted,the sustainable development of building industry is facing up to a severe test.As a vital part of the entire building consumption,the building lighting system has an inevitable trend to be environmental-friendly.Meanwhile,the application of the energy saving lighting technology will become an essential method of building energy conservation.The thesis researches the civil building lighting energy saving technology,aiming at promoting energysaving measures in the perspective of scientific and achieving the low-carbon and environmental-friendly of civil building lighting system.Through accessing to a large number of domestic and foreign information,reading the relevant specifications,and comprehending,integrating,analyzing,researching all of its contents,this thesis,which researches the application of the civil construction energy-efficient lighting technology,is accomplished eventually.And the key points of this paper are shown as follow:1.Based on the basic theory of the building lighting,research the possibility of energysaving lighting by the introduction and analysis of basic concepts,theory and calculation.The specific contents are shown as follow: firstly,the light measurement system,human visual characteristics and material's optical properties are introduced;secondly,analyzing the illumination calculation method,illustrating the lighting quality,the lighting style and the basic theory of electric light source and lamps and lanterns;thirdly,introducing the basic theory of building lighting power distribution;fourthly,analyzing the power supply types of electrical building lighting system,drawing forth the intelligent lighting control method,which energysaving effect is excellent;at last,the economical and technological analyzing methods of energy-saving lighting are proposed,supplying the basis for plans comparison.2.Combine both building lighting design basic theory and practice,propose five civil construction lighting energy-saving measures which feasibility are relatively high.Firstly,select the electric light source which is high light efficiency,long life and excellent economy,lamps and lanterns which is high efficiency,high lumen maintenance rate and high lumen utilization,and appurtenance which is low electrical loss.Secondly,configure the electric light source,lamps and lanterns reasonably,in order to achieve energy-saving,such as enhancing dimming coefficient and lamp utilization factor,improving the lighting quality,choosing reasonable lamp arrangement and lighting style,and using lighting simulation software for supporting design.Thirdly,the power quality shall be improved in the energy-saving design process of lighting distribution,reducing the transformer active loss,increasing the lighting line power factor,reducing the lighting line loss to achieve energy-saving.Fourthly,applying the intelligent lighting control system,adopting the exact energy-saving control strategies to reduce power consumption.Fifthly,taking advantage of natural light,combining lighting port,translucent materials,light guide tube and photovoltaic lighting with buildings to achieve energy-saving.3.Based on an actual project,a variety of lighting energy saving measures to be combined with the design,in line with norms,in order to get high lighting effect while achieving energy saving program.Utilize DIAlux for simulation design based on the grogram,then analyze and illustrate its energy-saving effect and economy.
