Research On Energy Saving Of Line-side High-speed Railway Station Waiting Hall Based On Visual Comfort

With the development of Chinese economy,science and technology,and the development of large-scale high-speed railway construction,the number of high-speed railway station houses has also shown a rapid growth trend in recent years.The rapid development of high-speed railways has also brought new challenges to China's sustainable development strategy^[1].How to ensure the construction of China's high-speed rail infrastructure,and on the basis of satisfying the functional construction,attention to comfort issues has become the development direction of today's high-speed rail construction.In the design of the waiting hall,attention to comfort and energy saving has become an important aspect of design thinking today.Natural light is a very efficient green energy source.How to take advantage of natural light and enhance the energy efficiency of indoor lighting in public buildings is of great significance.Indoor lighting comes from windows,and the specific shape,area,and orientation of windows are important factors that determine the efficient use of natural lighting.At present,in the design and construction of the waiting room of the high-speed railway station,more consideration is given to the shape requirements.Many high-speed railway stations use large-area glass materials on the facade or the top.This design often increases energy consumption,so it is reasonable in the design of the high-speed railway station The use of glass to balance comfort,aesthetics,and energy conservation has become the focus of this study.First of all,this paper summarizes the advantages and disadvantages of the existing light environment by conducting an actual survey on the waiting halls of existing high-speed railway stations.From the perspective of visual comfort^[2],a questionnaire survey is conducted for existing waiters and a subjective survey of valid questionnaires Evaluation and analysis,quantified visual comfort,proposed a proposal for energy saving of lighting while satisfying visual comfort,and proposed corresponding guidelines and assisted design for the construction of energy saving in the waiting hall of high-speed railway stations.And carry out experimental research on visual comfort,classify and compare the influencing factors of visual comfort,and obtain the change rule of influencing factors on visual comfort^[3].Secondly,establish a standard model of the waiting room of the high-speed railway station,and use Radiance,Daysim and other software to perform natural light simulation throughout the year,and conduct simulation research on different working conditions such as window opening method,area size and window opening direction.Use the simulated data to analyze the natural light data,and get the numerical values of natural light simulation evaluation DA,DF,UDI,etc.According to the results,analyze the advantages and disadvantages under different working conditions.According to the working condition model,DIALux evo performs lighting simulation analysis,and compares it with the results of the subjective visual comfort questionnaire survey to find out the optimal lighting energy saving scheme for the waiting halls of small and medium-sized high-speed railway stations under the comfort conditions.Station building design provides reasonable guidance.Through a multi-angle optimization research method,combining the natural light environment of the high-speed rail station with the energy saving of the waiting hall lighting,while waiting for the passenger,using the visual comfort angle of the passenger as the starting point,the physical quantity data obtained by software simulation experiments will be The window design of the high-speed railway station provides a reference to maximize the efficient use of natural light.Use lighting simulation software to optimize the lighting energy saving scheme for the waiting room of high-speed railway stations,adjust the power of light sources and the arrangement of lamps to reduce the LPD value,thereby reducing the energy consumption of indoor lighting;and provide corresponding energy-saving optimization strategies to save energy,Green building.
