    • Building Services Solutions Suitable for a Low Emission Urban Areas 

      Rønneseth, Øystein; Haase, Matthias; Georges, Laurent; Thunshelle, Kari; Holøs, Sverre Bjørn; Fjellheim, Øystein; Mysen, Mads; Thomsen, Judith (ZEN Report;26, Research report, 2020)
      It is believed that well-performing building envelopes with low thermal losses and low solar heat gains enable simplified building services solutions. The purpose of this report is to summarize the status of promising ...

    • Digitalisering av bygninger i drift. Hvor smarte er næringsbygninger i dag? 

      Andersen, Kamilla Heimar; Yang, Aileen; Holøs, Sverre Bjørn; Fjellheim, Øystein (SINTEF Fag;88, Research report, 2022)
      Europakommisjonens ambisjon om å bli verdens første klimanøytrale kontinent innen 2050 er avhengig av digitale teknologier og løsninger som kunstig intelligens (KI), 5G, tingenes internett (IoT), skytjenester og "edge ...

    • 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 (Peer reviewed; Conference object; Journal article, 2020)
      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 ...

    • Potensial- og barrierestudie. Energitjenester i næringsbygg 

      Fjellheim, Kristin; Lien, Synne Krekling; Walnum, Harald Taxt; Sandberg, Nina Holck; Cheng, Caroline Y; Fjellheim, Øystein (SINTEF rapport, Research report, 2021)
      Energibruk i næringsbygg unntatt industribygg utgjør 14 % (31 TWh i 2019) av total energibruk i Fastlands-Norge, og redusert energibruk i bygningsmassen er viktig i utviklingen av framtidens energisystem og for å frigjøre ...

    • 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 (Peer reviewed; Journal article, 2021)
      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 ...

    • VOC contributions from building materials, furniture, and user equipment in low emitting and modular classrooms 

      Yang, Aileen; Holøs, Sverre Bjørn; Hak, Claudia; Vogt, Matthias; Schmidbauer, Norbert; Fjellheim, Øystein (SINTEF Proceedings;9, Chapter; Peer reviewed; Conference object, 2021)
      This study aimed to assess whether building materials, furniture, and user equipment are sources of pollution that would influence the need for ventilation. Between 2017-2020, measurements were taken in four regular ...

    • ZEN Case Study. End User Flexibility Potential in the Service Sector 

      Lien, Synne Krekling; Ahang, M.; Lindberg, Karen Byskov; Fjellheim, Øystein (ZEN Report;27, Research report, 2020)
      The electricity grid is designed to handle peaks in electricity consumption and is usually dimensioned to handle peak loads at the coldest hours of the year. Over the years to come, investment plans in the Norwegian ...
