Abstract :
Energy conservation in buildings is becoming an issue of great importance. Space cooling is getting important in most
countries and different techniques have been developed one of which is radiative cooling. A prototype roof component,
exploiting radiative cooling, was built and tested in the outdoor test facilities of the Centre of Renewable Energy Sources
in Greece. The component comprises a radiator, which is utilizing water as the fluid medium and its cooling performance
was investigated. This paper presents the construction of the component, the experimental set-up and the results taken
during the monitoring procedure.
