Optimization of Skylight Lighting and Building Energy Consumption in Large Airport Terminal Buildings--Taking Changsha Huanghua Airport T3 as an Example
Green airport as an important content of the four airport construction,coupled with the terminal building itself has the characteristics of high space,long operation time,high energy consumption,and dense personnel,so the advantages and disadvantages of the skylight design is particularly critical to realize the airport green low-carbon goals.This paper takes Changsha Huanghua Airport T3 terminal building as an example,through the single-factor study and multi-factor coupling study of natural lighting,lighting energy consumption,air conditioning energy consumption and heating energy consumption in the skylight design of this project,concludes that the optimal area ratio of the skylight to its roof is ought to be 5-7%,meanwhile the recommended values of solar heat gain coefficient and thermal transmittance for skylights are not larger than 0.30 and 2.0 W/(m2·K),respectively.The purpose is to design an airport achieving optimal comprehensive energy through refined daylight analysis,and to provide a good demonstration effect and reference for the construction of green low-carbon airport in China.
