    • Possibilities for characterization of a PCM window system using large scale measurements 

      Grynning, Steinar; Goia, Francesco; Rognvik, Egil; Time, Berit (Journal article; Peer reviewed, 2013)
      The introduction of dynamic envelope components and systems can have a significant reduction effect on heating and cooling demands. In addition, it can contribute to reduce the energy demand for artificial lighting by ...

    • Responsive building envelope concepts in zero emission neighborhoods and smart cities - A roadmap to implementation 

      Taveres-Cachat, Ellika; Grynning, Steinar; Thomsen, Judith; Selkowitz, Stephen (Journal article; Peer reviewed, 2019)
      Designing a zero emission neighborhood (ZEN) from an energy point of view, has the benefit of distributing loads over time by creating a mosaic of buildings which individually may not have a zero emission balance, but reach ...

    • Robustness Classification of Materials, Assemblies and Buildings 

      Jelle, Bjørn Petter; Sveipe, Erland; Wegger, Erlend; Gustavsen, Arild; Grynning, Steinar; Thue, Jan Vincent; Time, Berit; Lisø, Kim Robert (Journal article; Peer reviewed, 2014)
      Reliable methods are needed for classifying the robustness of buildings and building materials for many reasons, including ensuring that constructions can withstand the climate conditions resulting from global warming, ...

    • Simulation and control of shading systems for glazed facades 

      Chaudhary, Gaurav; Goia, Francesco; Grynning, Steinar (Journal article; Peer reviewed, 2019)
      This paper presents a simulation study on the use of shading devices in highly glazed facades in the context of zero emission buildings (ZEB) located in a Nordic climatic context. Shading devices have the task to control ...

    • Solar efficiency index of building envelopes and load matching in low energy buildings 

      Taveres-Cachat, Ellika; Goia, Francesco; Grynning, Steinar (Chapter, 2018)
      Net-zero energy buildings oftentimes rely on solar-based building integrated technologies to offset energy use and achieve their goals. However, the value of a particular system is difficult to assess given that these ...

    • Solar shading control strategies in cold climates - Heating, cooling demand and daylight availability in office spaces 

      Grynning, Steinar; Time, Berit; Matusiak, Barbara Szybinska (Journal article; Peer reviewed, 2014)
      Modern office buildings often have large glazed areas. Incident solar radiation can lead to large cooling demands during hot periods although the solar radiation can help reduce heating demands during cool periods. Previous ...

    • Temperature and thermal comfort in office spaces: measurements vs. simulations 

      Lolli, Nicola; Brozovsky, Johannes; Nocente, Alessandro; Grynning, Steinar (Chapter, 2019)
      A deviation between the calculated and the measured data of energy use in buildings (known as performance gap) has been extensively reported. The aim of this study is to identify the underlying causes of the deviation ...

    • Thermal improvements of box-window using shading attachments. Hot-box measurements 

      Misiopecki, Cezary; Grynning, Steinar; Gustavsen, Arild (Peer reviewed; Journal article, 2023)
      This research explores shading potential for improving the thermal properties of a box-window. Two different types of shades along with three placements were considered. Ten configurations were tested in a hot-box apparatus ...

    • Transparent facades in low energy office buildings Numerical simulations and experimental studies 

      Grynning, Steinar (Doctoral thesis at NTNU;2015:112, Doctoral thesis, 2015)
      Windows are a key component in the building envelope. They are often, thought of as energy drains and something associated with excessive energy demands in a building. However, in order to assess the energy performance ...

    • Vacuum Insulation Panels for Building Applications: A Review and Beyond 

      Baetens, Ruben; Jelle, Bjørn Petter; Thue, Jan Vincent; Tenpierik, Martin J.; Grynning, Steinar; Uvsløkk, Sivert; Gustavsen, Arild (Journal article; Peer reviewed, 2010)
      Vacuum insulation panels (VIPs) are regarded as one of the most promising high performance thermal insulation solutions on the market today. Thermal performances 3 to 6 times better than still-air are achieved by applying ...

    • Vinduer for energieffektive bygninger: Kuldebroer ved vindusinnsetting 

      Decheva, Larisa Marinova (Master thesis, 2012)
      Vinduer har mange oppgaver. De sikrer dagslystilførsel og solvarmetilskudd, formidler visuell kontakt, gir ventilasjons muligheter og kan fungere som rømningsveg. Men vinduenes termiske egenskaper fører til et større ...

    • Windows in the Buildings of Tomorrow; Energy Losers or Energy Gainers? 

      Grynning, Steinar; Gustavsen, Arild; Time, Berit; Jelle, Bjørn Petter (Journal article; Peer reviewed, 2013)
      One of the most effective actions for reduction of energy loss through the building envelope is to optimize the thermal performance, area and localization of the transparent components in the façade in order to obtain ...
