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

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Thomas Thorsell; KTH.; [2012]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  4. 4. Studies on Building Air Leakage -a transient pressurisation method, measurements and modelling

    Detta är en avhandling från Department of Fire Safety Engineering and Systems Safety, Lund University

    Författare :Björn Mattsson; [2007]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; air change rate; Airtightness; CFD-simulations; moisture transport; air leakage; mould growth; cold attics; transient pressurisation;

    Sammanfattning : Airtightness of the building envelope is a key factor for good performance of a building. The main part of this thesis deals with the exploration of a transient pressurisation method for air leakage measurements.In the transient method, an enclosure is pressurised to a desired pressure. The air flow into the enclosure is then stopped. LÄS MER

  5. 5. Fire temperature development in enclosures Some theoretical and experimental studies

    Detta är en avhandling från Luleå : Luleå tekniska universitet

    Författare :Alexandra Byström; Luleå tekniska universitet.; [2013]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stålbyggnad; Steel Structures;

    Sammanfattning : This thesis is devoted to problems connected to heat transfer and fire dynamics in enclosures. The thesis consists of a main part which summarizes and discusses the theory of heat transfer, conservation of energy and fire dynamics. Based on these theories, some cases of different fire scenarios have been analyzed. LÄS MER
