This book reports on a study of the renewable energy- based heating and cooling systems of a multipurpose building. The first objective of the investigation was to demonstrate the potential of solar-assisted cooling, the second focused on the total energy balance of the building. For base-load heating and cooling, the building is equipped with a ground source heat pump, supplied by a ground storage. For solar cooling, the building is equipped with solar collectors and two desiccant evaporative cooling (DEC) plants. During the first year of operation, significant problems occurred in the...
