What are the effects of thermal bridging in metal outdoor sculptures attached to buildings?

Thermal bridging in metal outdoor sculptures attached to buildings can lead to several significant effects. First, it causes heat transfer between the sculpture and the building, potentially increasing energy loss and reducing thermal efficiency. This can raise heating or cooling costs for the structure. Second, temperature differences may result in condensation, leading to moisture buildup and potential corrosion or mold growth. Additionally, repeated thermal expansion and contraction can stress both the sculpture and the building's facade, risking structural damage over time. Proper insulation and design considerations are essential to mitigate these issues while maintaining artistic integrity. Understanding these effects helps artists and architects create durable, energy-efficient installations.
