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

    Författare :Thomas Thorsell; Folke Björk; Mark Bomberg; Targo Kalamees; KTH; []
    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

    Sammanfattning : 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. LÄS MER

  4. 3. An Approach Towards Sustainable Building

    Författare :Navid Gohardani; Folke Björk; Kjartan Gudmundsson; Göran Lindahl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainability; Built environment; Sustainable renovation; High-efficient insulation materials; Sweden Green Building Council; Vacuum Insulation Panels VIP ; Decision making; GreenBuilding; Early stage; Stakeholders; A Concept for promotion of sustainable retrofitting and renovation in Early Stages ACES ; Early Stage Primary Energy Estimation Tool ESPEET ;

    Sammanfattning : The motivation for development of energy efficiency and implementation of novel advanced materials applied in buildings can be traced to increasing energy costs in conjunction with an enhanced environmental awareness among people. This doctoral dissertation presents contributions towards sustainable building, where factors such as building technology, energy efficiency in buildings, workers' health issues during construction measures, and certain economic considerations for renovation of buildings have been considered.

  5. 4. Sami lifestyle and health : epidemiological studies from northern Sweden

    Författare :Lena Maria Nilsson; Bethany Van Guelpen; Anna Winkvist; Per Lenner; Per Sjölander; Peter Bjerregaard; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sami people; traditional food; traditional lifestyle; the VIP cohort; mortality; cancer; cardiovascular disease; folkhälsa; Public health;

    Sammanfattning : The aim of this PhD thesis was to expand the current knowledge of “traditional Sami” diet and lifestyle, and to test aspects of the Sami diet and lifestyle, specifically dietary pattern, macronutrient distribution and coffee consumption, in population-based epidemiological studies of mortality and incident cardiovascular disease and cancer in a general population.In Paper I, semi-structured interviews were conducted with 20 elderly Sami concerning their parent’s lifestyle and diet 50-70 years ago.

  7. 5. Retrofitting of old Exterior Wall with Vacuum Insulation Panels: Measurements of Thermal Properties, Moisture Performance and Practical Considerations

    Författare :Pär Johansson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hygrothermal sensor; listed building; transient plane source; retrofitting; indoor moisture supply; vacuum insulation panel; hygrothermal simulation; exterior wall;

    Sammanfattning : The building industry is facing one of its most challenging tasks ever. Until 2050 the energy use for heating of buildings should be decreased by 50% which means a large part of the building stock have to be retrofitted to become more energy efficient. One of the possible solutions is to add thermal insulation to the exterior wall of the buildings. LÄS MER
