The pilot study InnoGOK investigated the possible use of solar energy of sealed surfaces (traffic areas, parks, places and paths) in view of the problem of urban heat islands. The test facility of the HTL Krems is equipped with suitable test surfaces (asphalt, concrete and grass surfaces) and storage media (ice storage and earth storage), which were technically adapted and supplemented with measuring equipment during the study. The results of the so gained solar energy als well as the possible storage of this energy were then transformed to urban scales. The direct or phase shifted use ot the energy gained (e.g. service water heating, heat pump support, keeping traffic areas free of ice) was also shown within this project.
