Impact of Typical Faults Occurring in Demand-controlled Ventilation on Energy and Indoor Environment in a Nordic Climate
Andersen, Kamilla Heimar; Holøs, Sverre Bjørn; Yang, Aileen; Thunshelle, Kari; Fjellheim, Øystein; Jensen, Rasmus (E3S Web of Conferences;Volume 172, 09006 (2020, Journal article; Peer reviewed, 2020-06-30)This study evaluates typical faults occurring in demand-controlled ventilation (DCV) system and the impact on three output results: energy use, thermal comfort, and indoor air quality. The methodologies used in this study ... -
Temperature-dependent ventilation rates might improve perceived air quality in a demand-controlled ventilation strategy
Yang, Aileen; Holøs, Sverre Bjørn; Opsahl Resvoll, Marie; Mysen, Mads; Fjellheim, Øystein (Building and Environment;Volume 205, November 2021, 108180, Peer reviewed; Journal article, 2021-07-24)The aim of the Best Vent project was to find the optimal control strategy for demand-controlled ventilation (DCV) without compromising on indoor air quality. In this paper, we discuss control strategies that would ensure ... -
