    • 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 ...

    • Local loss coefficients inside air cavity of ventilated pitched roofs 

      Gullbrekken, Lars; Uvsløkk, Sivert; Geving, Stig; Kvande, Tore (Journal article; Peer reviewed, 2018)
      Pitched roofs with a ventilated air cavity to avoid snow melt and ensure dry conditions beneath the roofing are a widely used construction in northern parts of Europe and America. The purpose of this study has been to ...

    • Wind pressure coefficients for roof ventilation purposes 

      Gullbrekken, Lars; Uvsløkk, Sivert; Kvande, Tore; Pettersson, Kaj; Time, Berit (Journal article; Peer reviewed, 2018)
      Wind pressure coefficients (cp) are important inputs for analytical calculations of wind load. The aim of this research is to investigate wind pressure coefficients on a test house located in Norway in order to pave the ...
