Thermal conductivity of monodisperse silica nanospheres
Gao, Tao; Jelle, Bjørn Petter; Sandberg, Linn Ingunn; Gustavsen, Arild (Journal article; Peer reviewed, 2015)Monodisperse hollow silica nanospheres (HSNSs) with an outer diameter of ∼300 nm and shell thickness of ∼50 nm were prepared via a spontaneous dissolution–regrowth process of solid silica nanospheres (SSNSs) in NaBH4 aqueous ... -
Thermal Conductivity of TiO2 Nanotubes
Gao, Tao; Jelle, Bjørn Petter (Journal article; Peer reviewed, 2013)Thermal conductivity of TiO2 nanotubes prepared from a NaOH treatment of TiO2 particles with subsequent acid washing and annealing has been investigated. The obtained TiO2 nanotubes have a tetragonal anatase structure, and ... -
Thermal Modeling and Investigation of the Most Energy-Efficient Window Position
Misiopecki, Cezary; Bouquin, Marine; Gustavsen, Arild; Jelle, Bjørn Petter (Journal article; Peer reviewed, 2018)The energy consumption in buildings contributes substantially to the worldwide energy use and greenhouse gas emissions. One of the crucial elements defining energy consumption is the building envelope, which in modern ... -
Thermal Superinsulation for Building Applications - From Concepts to Experimental Investigations
Jelle, Bjørn Petter; Gao, Tao; Sandberg, Linn Ingunn Christie; Tilset, Bente Gilbu; Grandcolas, Mathieu; Gustavsen, Arild (Journal article, 2014)The application of traditional thermal insulation materials requires thicker building envelopes in order to satisfy the requirements of the emerging zero energy and zero emission buildings. This work summarizes the steps ... -
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 ... -
Vacuum Insulation Panels in Wood Frame Wall Constructions with Different Stud Profiles
Haavi, Thomas; Jelle, Bjørn Petter; Gustavsen, Arild (Journal article; Peer reviewed, 2012)In this work, the thermal performance of three different wall configurations was examined by hot box measurements and numerical simulations. Vacuum insulation panels were sandwiched between traditional insulation in walls ... -
Visible-Light-Driven Photochromism of Hexagonal Sodium Tungsten Bronze Nanorods
Gao, Tao; Jelle, Bjørn Petter (Journal article; Peer reviewed, 2013)Single-crystalline sodium tungsten bronze (Na-WO3) nanorods with typical diameters of 10–200 nm and lengths of several micrometers were prepared via hydrothermal synthesis. The as-prepared Na-WO3 nanorods crystallized in ... -
Window spacers and edge seals in insulating glass units: A state-of-the-art review and future perspectives
Van den Bergh, Sofie M G; Hart, Robert; Jelle, Bjørn Petter; Gustavsen, Arild (Journal article; Peer reviewed, 2013)Insulating glass (IG) units typically consist of multiple glass panes that are sealed and held together structurally along their perimeters. This report describes a study of edge seals in IG units. First, we summarize the ... -
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 ...
