Domestic Hot Water and Cooling Demand Coverage for Nearly Zero Energy Buildings Applying Combined Solar Heating and Radiative Cooling
Abstract
A new device capable to combine night radiative cooling and solar thermal collection (called Radiative Collector and Emitter, RCE) is analyzed to determine its potential to cover the Domestic Hot Water (DHW) and cooling demands for a single family detached house following nearly Zero Energy Building (nZEB) standards. The energy demand of the considered house is compared to the energy (heat and cold) production of the RCE in order to determine the potential for demand coverage. Results show best coverages can be achieved for climates Csb and Cwb of the Köppen-Geiger climate classification.
