Common problems of indoor thermal environment in glass curtain wall buildings in winter

The thermal performance and optical performance of the exterior envelope of glass curtain wall buildings have a great influence on the thermal comfort of indoor environment. Based on the examples of the diagnosis and commissioning of variable air volume central air conditioning system of glass curtain wall buildings completed by the authors team, sorts out the common problems of indoor thermal environment in winter, including indoor overheating, uneven heating and cooling, and indoor overcooling. Analyses the causes of the problems from three aspects: building load characteristics, design and operation of air conditioning system and curtain wall construction technology, and proposes the solutions, providing references for relevant design, construction and operation personnel.
