    • 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 ...

    • Should we differentiate ventilation requirements for different user groups? 

      Holand, Nora; Yang, Aileen; Holøs, Sverre Bjørn; Thunshelle, Kari; Mysen, Mads (Springer Proceedings in Energy;Cold Climate HVAC 2018 - Sustainable Buildings in Cold Climates, Conference object, 2018-12-12)
      The aim of our study is to investigate whether it is necessary to adjust the venti-lation requirements according to different user groups. This study is focusing es-pecially on teenagers, who might have a higher odour load ...

    • VOC emission rates in newly built and renovated buildings, and the influence of ventilation – a review and meta-analysis 

      Holøs, Sverre Bjørn; Yang, Aileen; Lind, Merethe; Thunshelle, Kari; Schild, Peter; Mysen, Mads (The International Journal of Ventilation;, Journal article; Peer reviewed, 2018-02-20)
      Few field studies have evaluated ventilation strategies, such as temporarily increasing the ventilation rate, to counter the high pollutant-load from off-gassing of volatile compounds from new materials in these buildings. ...

    • What should the Minimum Ventilation Rate Be in a Demand-Controlled Ventilation Strategy? 

      Mysen, Mads; Holøs, Sverre Bjørn; Yang, Aileen; Thunshelle, Kari; Schild, Peter (Springer Proceedings in Energy;CCC 2018: Cold Climate HVAC 2018, Conference object, 2019)
      Demand-Controlled Ventilation is emerging as a dominant ventilation strategy in non-residential buildings in Norway. The ventilation airflow rate is controlled between pre-set minimum (Vmin) and maximum (Vmax) values, based ...
