Working With a Small and Predictable Performance Gap
(SINTEF Proceedings;5, Chapter; Peer reviewed; Conference object, 2020)Much is written about the performance gap. Multi- ple studies show alarming discrepancies between de- sign and actual building energy performance. Should this prove to be a universal truth, the need of more detailed dynamic ... -
Visualizing user perception of daylighting: a comparison between VR and reality
(SINTEF Proceedings;5, Chapter; Peer reviewed; Conference object, 2020)This study introduces a novel method to investigate human perception of daylight in an interactive and immersive way, using game-engine and virtual reality (VR). The proposed method produces highly realistic renderings in ... -
Quasi-Dynamic Modelling of DC Operated Ground-Source Heat Pump
(SINTEF Proceedings;5, Chapter; Peer reviewed; Conference object, 2020)The performance of a conventional ground-source heat pump (GSHP) has been measured in the laboratory with alternating current (AC) and direct current (DC) operation using the standardised points from EN14511:2018. The ... -
Solar PVT for heat pumps: Collector development, systems integration, and market potential
(SINTEF Proceedings;5, Chapter; Peer reviewed, 2020)Solar PV/thermal hybrid collectors have been researched for decades, but have never had market success. This paper motivates a research agenda for PVT based on heat pump integration. The market potential is defined and ... -
