Original Abstract

Radiant wall systems present a potentially feasible solution for building retrofit which could be preferable to the more common radiant floors and ceilings due to several benefits. The wall systems can be tailored for the specific situation by varying the configuration and thermal properties of the material layers. In this study, we focus on two types of wall cooling systems. The first system has pipes attached to the outer side of the facades of existing buildings. This system was compared with a wall system with pipes embedded underneath the surface in inner plaster. A sample of experimental and computational results is presented to demonstrate the possibilities and limitations of applying these systems in existing buildings. The system with pipes attached to the facades can provide a reasonable thermal output if properly designed. It might be preferable in situations when interventions on the inner side should be avoided. The system with pipes in plaster underneath the surface can be used both on facades and inner walls. Especially when combined with a thermally insulating core made of, e.g., aerated concrete it provides a rapid thermal response and high thermal output and can be very suitable for building retrofit.
