  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. A Sociological Approach to Indoor Environment in Dwellings : Risk factors for Sick Building Syndrome (SBS) and Discomfort

    Author : Karin Engvall; Dan Norbäck; Eva Sandstedt; Göran Strid; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Medicine; Indoor environment; Questionnaire; Atopy; Building age; Indoor air quality; Sick building syndrome SBS ; Validation; Dwelling; Energy conservation; Mechanical ventilation; Building dampness; Building reconstruction; Wood heating; Electric heating; Heat pump; Thermal Insulation; Sealing; Medicin; Dermatology and venerology; clinical genetics; internal medicine; Dermatologi och venerologi; klinisk genetik; invärtesmedicin; arbets- och miljömedicin; Occupational and Environmental Medicine;

    Abstract : The principal aim was to study selected aspects of indoor environment in dwellings and their association with symptoms compatible with the sick building syndrome (SBS). A validated questionnaire was developed specifically for residential indoor investigations, using sociological principles and test procedures. READ MORE

  4. 4. Heat conduction in two and three dimensions : computer modelling of building physics applications

    Author : Thomas Blomberg; Avdelningen för Byggnadsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; civil engineering; building physics; thermal radiation; numerical modelling; Heat conduction; computer programs;

    Abstract : The first aim of this doctoral work has been to develop a new generation of computer programs for transient and steady-state heat conduction in two and three dimensions. A large range of heat transfer problems within the field of buildings physics can be analyzed using these tools. READ MORE

  5. 5. 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
