A Study Of Energy-saving Design In Terminal Buildings In The Third Expansion Project Of Dalian International Airport

With the rapid development of China’s airport construction,compared with the general public buildings,the airport building consumes a lot of energy,and the airport terminal is a large energy user.Dalian airport terminal has high requirement for heating and cooling,so it has high energy consumption intensity and huge energy saving potential.In the future,it is urgent to study the energy saving design of airport terminal.Taking the third terminal of dalian airport as an example,this paper takes the planning stage,individual buildings,overall environment and resource design elements as the entry point to carry out research,aiming to explore the energy-saving integrated design methods and tools in line with the operation logic of reconstruction and expansion.This paper systematically reviews the ways and design methods of airport terminal energy saving at home and abroad,and points out the deficiencies of airport energy saving design in China.It is divided into four chapters.The first chapter is the introduction,which analyzes the research background and significance of airport energy-saving design,as well as relevant case studies and practical results at home and abroad.The second chapter makes a detailed analysis from the four aspects of planning and design,single building design,overall environment design and resource recycling and utilization,summarizes and summarizes the basic elements of airport energy conservation design,and reveals the basic strategies of airport energy conservation design.The third chapter focuses on the energy saving design of the third phase expansion project of dalian international airport.The fourth chapter combined the problems and deficiencies in terminal design,put forward the relevant rectification measures and strategies.In this paper,the terminal building energy saving design has been evaluated,while putting forward the corresponding optimization scheme.The physical environment design was optimized,and the enclosure structure was transformed into a double-layer breathing curtain wall.The sun visor was used to solve the problem of sunlight in the west,and the atrium and side atrium were used to solve the problem of natural lighting in the ground floor.In terms of the overall environment optimization of the terminal,the problems of indoor lighting are solved through the design optimization of outdoor landscape greening,base water-retaining capacity,indoor space and artificial lighting.The optimization of resource recovery and utilization is mainly aimed at water resource recovery and utilization and the economical utilization and recovery of various types of consumables.Based on the above research results,an effective energy saving scheme in line with the climate characteristics of Dalian was summarized,and the appropriate energy saving scheme was adopted to reduce energy consumption on the basis of ensuring the comfort level of the airport,providing a reference for the construction of energy-saving airports in the same type of cities.
