Preliminary test and analysis of thermal environment and thermal comfort characteristics of composite ice shell structure buildings

As a new type of ice and snow buildings, the composite ice shell structure building has high artistic appreciation, but there is a lack of research on its internal thermal environment and thermal comfort. In this paper, the indoor and outdoor environment characteristic parameters of the ice restaurant and the thermal response vote of the subjects are obtained through a three-day objective test and subjective survey of the ice restaurant project of Harbin Ice and Snow World in 2021. Based on the result, a thermal sensation prediction model for composite ice shell structure buildings is established, which provides theoretical guidance for the design of indoor parameters of these buildings.
