  1. 1. Advances in Thermal Insulation : Vacuum Insulation Panels and Thermal Efficiency to Reduce Energy Usage in Buildings

    Author : Thomas Thorsell; Folke Björk; Mark Bomberg; Targo Kalamees; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vacuum insulation panels; VIP; serpentine edge; thermal bridge; composite film; gas diffusion; defect dominated; holistic approach; building enclosure; integrated testing and modeling; energy equivalent; field performance; air flow; thermal insulation efficiency;

    Abstract : We are coming to realize that there is an urgent need to reduce energy usage in buildings and it has to be done in a sustainable way. This thesis focuses on the performance of the building envelope; more precisely thermal performance of walls and super insulation material in the form of vacuum insulation. READ MORE

  2. 2. Vacuum insulation in buildings : Means to prolong service life

    Author : Thomas I. Thorsell; Gudni Jóhannesson; Christer Sjöström; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum insulation; thermal bridge; serpentine edge; coated film; Building engineering; Byggnadsteknik;

    Abstract : Vacuum insulation panels, VIPs, constitute a new insulation material, 6 to 8 times better than traditional insulation materials, which utilizes the positive influence vacuum has on the thermal properties of certain materials. A VIP is a composite with a flat core enclosed by an envelope preventing the core to fill with gas. READ MORE

  3. 3. Building Retrofit using Vacuum Insulation Panels: Hygrothermal Performance and Durability

    Author : Pär Johansson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory; retrofitting; interior insulation; listed building; field study; exterior wall; brick wall; numerical simulation; wooden beam ends; measurement; vacuum insulation panel; transient plane heat source; exterior insulation;

    Abstract : Many old buildings have unsatisfactory thermal performance compared to the standards of today. One way to increase the thermal performance is to add thermal insulation to the building envelope. However, many old buildings are listed and considered to be valuable for historical and esthetic reasons. READ MORE

  4. 4. Robust and Durable Vacuum Insulation Technology for Buildings

    Author : Peyman Karami; Folke Björk; Kjartan Gudmundsson; Jan Akander; KTH; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Vacuum Insulation panels VIPs ; Million Program; Energy saving; Thermal conductivity; thermal transmittance U-value ; Thermal bridges; Stationary and transient measurements; Dynamic simulations of heat and moisture conditions; Full scale measurement in climatic chamber; LCA; Vakuumisoleringspaneler VIP:ar ; Miljonprogrammet; Energibesparing; Värmeledningsförmåga; värmegenomgångskoefficient U-värdet ; Köldbryggor; Stationära och transienta mätningar; Dynamiska simuleringar av värme och fuktförhållanden; Fullskaleförsök i klimatkammare; LCA; Civil and Architectural Engineering; Byggvetenskap;

    Abstract : Today’s buildings are responsible for 40% of the world’s energy use and also a substantial share of the Global Warming Potential (GWP). In Sweden, about 21% of the energy use can be related to the heat losses through the climatic envelope. READ MORE

  5. 5. Assessment of novel applications for nano-porous thermal insulation in district heating pipes and building walls

    Author : Axel Berge; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive façade; nano-porous insulation; thermal insulation; district heating pipes; hybrid insulation;

    Abstract : In nano-porous thermal insulation there is a strong relation between the pressure and the thermal conductivity, even at pressures close to atmospheric pressure. This thesis presents research on applications of nano-porous insulation in hybrid insulation district heating pipes and in building walls. READ MORE
