  1. 6. Moisture Safety in Wood Frame Buildings - Blind evaluation of the hygrothermal calculation tool WUFI using field measurements and determination of factors affecting the moisture safety

    Författare :Solof Mundt Petersen; Avdelningen för Byggnadsfysik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blind Validation; Moisture Safety; Hygrothermal Calcualtion Tool WUFI; Wood Frame Buildings;

    Sammanfattning : Due to increased awareness of climate change and higher energy costs, well-insulated buildings have become more common. Furthermore, interest in the use of wood in building to produce more carbon dioxide-efficient buildings has increased. LÄS MER

  3. 7. Experimentella studier av värmeflöden och värmelagring i ett bebott flerbostadshus

    Författare :Lars Stenlund; Gunnar Bäckström; Olov Sandberg; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Energy balance; heat storage; heat flow; night setback; buildings; time constants;

    Sammanfattning : The study is experimentally inclined, with a high target precision for performance measurement. A comprehensive programme of measurements was carried out in a two-storey building, having a massive structure and dating from 1970. Measurements were made continuously during the heating season from a total of about 70 points. LÄS MER

  4. 8. Transmission loss of vehicle seals

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vehicle seals; reverberation room test; contact analysis; simple model; mass law; FEM analysis; distorted circular duct model; Acoustics; Akustik;

    Sammanfattning : Sound transmission loss of vehicle seals was studied in this thesis. Reverberation room test and semi-anechoic chamber test were respectively studied. LÄS MER

  5. 9. Indoor air quality and chemical emissions of organic compounds in newly built low-energy preschools

    Författare :Josefin Persson; Thanh Wang; Jessika Hagberg; Pim Leonards; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Indoor air quality; volatile organic compounds; brominated flame retardants; organophosphate flame retardants; low-energy preschools; environmental certification; indoor dust; surface wipes;

    Sammanfattning : In 2010, the European Union (EU) introduced the “Energy performance of Buildings” directive, which stipulates that all new buildings must reduce their energy consumption by constructing low-energy buildings. This could be achieved by constructing airtight and energy efficient envelopes with functional building materials such as age-resistant plastic films, insulation and different sealing products.

  7. 10. Numerical Modelling of Some Engineering Heat Transfer Problems

    Författare :Daniel Eriksson; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; Energiforskning;

    Sammanfattning : Engineering heat transfer problems are very often of a complex nature and most often no analytical solutions exist. One way to create solutions to such problems is to apply numerical methods. This study concerns heat transfer problems with coupled conduction, convection and thermal radiation. LÄS MER
