Study On Window Opening Form Of Terminal Check-in Hall In Northern China Based On Natural Lighting And Energy Consumption Simulation

The development of transportation,such as aviation and subway,often marks the advanced level of a city,and as the "heart" of an airport,the role of terminal buildings is very important,and it is not only a transportation hub of a city.It also represents the regional image of the city.Compared with other large-scale public buildings,the functions of terminal buildings are more complex,the indoor environment needs to be comfortable all the year round,and the requirements of supporting facilities are more perfect.But behind these conditions is huge energy consumption.With the development of the city,the number of airport construction continues to increase,the reconstruction and expansion continue,the energy consumption of the terminal building is also increasingly prominent,the terminal building check-in hall,the use frequency is extremely high,the space is tall,and the energy consumption intensity per unit area is high.It has great energy saving potential.This article starts with the window opening form of the check-in hall,through the field investigation of the airport terminal check-in hall in the northern region,combs the present situation of the terminal building,sums up the spatial scale characteristics of the terminal check-in hall,and establishes the typical model.On the basis of the simplification of the model,the parameter setting of the envelope structure and the setting of the indoor parameters,the position,the ratio and the form of the opening window of the terminal building check-in hall are simulated and studied by means of digital simulation and analysis technique.Firstly,the basic law of the influence of window opening on natural lighting and energy consumption of check-in hall is explained.Secondly,according to the multivariable experimental method,the optimal window opening ratio range of natural lighting is obtained.Then through the simulation study,the results of energy consumption under the different windows ratio of the terminal building in northern China are obtained,and the lowest energy consumption range is obtained.Finally,based on the comprehensive analysis of natural lighting and low energy consumption,the proportion range of windows is obtained,which not only meets the natural lighting standard but also meets the requirements of low energy consumption of buildings.
