• Air leakage paths in buildings: Typical locations and implications for the air change rate 

      Gullbrekken, Lars; Bunkholt, Nora Schjøth; Geving, Stig; Rüther, Petra (Peer reviewed; Conference object; Journal article, 2020)
      The harsh Norwegian climate requires buildings designed to high standards. An airtight building envelope is crucial to achieve an energy efficient building and to avoid moisture problems. Results from the SINTEF Building ...
    • Compact wooden roofs with smart vapour barrier – Pilot project experiences 

      Bunkholt, Nora Schjøth; Gullbrekken, Lars; Geving, Stig; Kvande, Tore (Peer reviewed; Conference object; Journal article, 2020)
      Compact roofs are normally built without organic materials between the vapour barrier and the roof membrane due to moisture safety risks. However, laboratory measurements indicate that organic materials could be used ...
    • Efficiency of BIPV system – Field study in Norwegian climate 

      Gullbrekken, Lars; Bunkholt, Nora Schjøth; Grynning, Steinar; Bellman, Martin; Kvande, Tore (1st Nordic conference on Zero Emission and Plus Energy Buildings, Conference object; Journal article; Peer reviewed, 2019)
      Use of solar cells (PV) and solar collectors are key remedies in buildings where a large part of the energy supply should be based on renewable energy. The aim of this work has been to evaluate calculated and measured solar ...
    • Er utvendig nedløp fra kompakte tak mulig? 

      Andenæs, Erlend; Skagseth, Vegard Andre; Bunkholt, Nora Schjøth (Journal article, 2020)
      Klimaendringer gir i Norge en økt mengde regn, som i urbane områder kan gi økt press på overvannssystemer. Derfor stilles det stadig oftere krav til å avlaste overvannsnettet ved å lede avrenning fra tak ut på terreng i ...
    • Experiences with external drainage systems from compact roofs in Norwegian climates 

      Andenæs, Erlend; Skagseth, Vegard Andre; Bunkholt, Nora Schjøth; Kvande, Tore; Lohne, Jardar (Peer reviewed; Conference object; Journal article, 2020)
      To reduce loads on urban drainage systems and facilitate local infiltration of stormwater, it is desired to lead runoff water from roofs through external drains and into the local soil. However, in cold climates, situations ...
    • Experimental Study of Thermal Buoyancy in the Cavity of Ventilated Roofs 

      Bunkholt, Nora Schjøth; Säwén, Toivo; Stockhaus, Martina; Kvande, Tore; Gullbrekken, Lars; Wahlgren, Paula; Lohne, Jardar (Journal article; Peer reviewed, 2020)
      Pitched wooden roofs are ventilated through an air cavity beneath the roofing in order to remove heat and moisture from the roof construction. The ventilation is driven by wind pressure and thermal buoyancy. This paper ...
    • Influence of Local Weather Conditions on Ventilation of a Pitched Wooden Roof 

      Bunkholt, Nora Schjøth; Gullbrekken, Lars; Kvande, Tore (Journal article; Peer reviewed, 2020)
      This paper investigates the influence of temperature and wind conditions on ventilation of the air cavity beneath the roofing in a full-scale pitched wooden roof construction. The potential for condensation in the air ...
