Thermal comfort and energy savings through cool elastomeric roof coatings

The design of a cool roof considers high reflectivity of sunlight leading to reduced absorption of heat by the building. The temperature in the rooms underneath the roof can be reduced and therefore air conditioning systems require less energy. Cool roofs can be made by applying a liquid coating, a sheet membrane, or highly reflective tiles or shingles. Our paper focuses on highly reflective elastomeric roof coating technology which also provides outstanding hydrolytic stability and excellent dirt pick-up resistance. The investigations of cool roofs on the indoor temperature and energy performance has been simulated considering specific building characteristics and climate conditions. We will also share measured energy savings and thermal comfort data for cool roofs in real case examples.
