Simulation And Optimization Of Natural Lighting And Energy Consumption In A Train Station

In line with the social development and improvement of living standards, the demand of people's comfort is growing, while the world is also faced with the current situation of energy shortage, which makes the needs of modern life and the availability of resources supplying formed a pair of contradictions. As a large-scale civil construction, railway stations bears a huge, complex and frequent flow of people. For this reason, the train station requires a high demand on light environment, hot environment.Firstly I introduce the basic theory of natural lighting, including the lightening climate ,the standards of natural lighting, the form of lightening, lighting design and lighting calculation. The beginning introduction will be followed by the basic information about one train station as an example. When One major area of translucent roof reach 22.3 percent and use the lighting of the north-south layout as the typical object ,we do the research of the lighting effects. Including: lower layer, train exit and the natural lighting coefficient distribution; waiting hall, entrance hall and the station platform in sunny weather at the Office of the annual illumination and the corresponding changes in the situation of human feelings, and analysis about the situation of " Lighting excess ";the exit hall to stand in the whole cloudy day at the indoor illumination, of" inadequate lighting ",the situation and the important work of these two surface of uniformity of light , At the same time, also on three different translucent roof area of 10%, 22.3%, 25.6% in a fixed transparent material with the lighting effects compared to a simulation study, and more options by comparing the energy consumption of lighting To measure differences in energy-saving measures, finally made the lighting and energy-saving measures to optimize the views and suggestions by checking energy consumption targets of air-conditioning .
