Balconies in the Shanghai, thermal bridges or sun shadings?
Ye YangAbstract: In the Cfa climate area, such as the city of Shanghai, balconies have two impacts on the thermal performance of the envelope, reducing solar gains passing through glazing and increasing heat loss flowing through the thermal bridges. The former one is the benefit of the building element, and the latter is yet the drawback. The paper compares the reduced solar radiation during cooling season with the additional heat transfer during heating season. It is found that the benefit is the overwhelming factor throughout the year’s energy balance. Besides, the additional rate of heat loss from the balconies are computed, the common construction of balconies insulation is discussed as well.
