Impact of a Large Implementation of ZEBs in the Norwegian Power System
Dyrendahl, Tore (Master thesis, 2016)In the Energy Performance of Buildings Directive (EPBD), all new buildings are said to be nearly Zero Energy Buildings (ZEBs) from 2018/2020. A Zero Energy Building is a building that has a lower demand for energy, and is ... -
Impact of PV and variable prices on optimal system sizing for heat pumps and thermal storage
Fischer, David; Lindberg, Karen Byskov; Madani, Hatef; Wittwer, Christof (Journal article; Peer reviewed, 2016)Heat pump (HP) units coupled to thermal storage offer flexibility in operation and hence the possibility to shift electric load.
