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

    Författare :Pär Johansson; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 7. Radiation properties of coil-coated steel in building envelope surfaces and the influence on building thermal performance

    Författare :Ali Joudi; Bahram Moshfegh; Mats Rönnelid; Harald Svedung; Mathias Cehlin; Runming Yao; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy and Built Environments; Energi och samhällsbyggnad;

    Sammanfattning : Recent studies have shown that the optical properties of building exterior surfaces are important in terms of energy use and thermal comfort. While the majority of the studies are related to exterior surfaces, the radiation properties of interior surfaces are less thoroughly investigated. LÄS MER

  4. 8. Energy efficiency and carbon dioxide mitigation in building stocks-

    Författare :Erika Mata Las Heras; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis investigates the implementation of energy-saving measures (ESM) in existing building stocks from an energy systems perspective. The effects of the measures are assessed in terms of net and delivered energy levels, carbon dioxide (CO2) emissions, and the costs for implementing the measures. LÄS MER

  5. 9. Influence of building envelope on indoor air quality: Field measurements, analysis, and method development related to indoor odors

    Författare :Fredrik Domhagen; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; material emissions; VOC; odor; ventilation; indoor air quality;

    Sammanfattning : The ventilation system should provide occupants with fresh air while removing excess pollutants from the building. However, increasing ventilation may inadvertently draw more pollutants into the occupant area or prove ineffective in altering emission rates from building materials and furnishings. LÄS MER

  7. 10. Industrial Construction Methods for Cost-Effective and Sustainable Multi-Storey Buildings

    Författare :Hanif Pourghazian; Folke Björk; Anne Landin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building engineering; Byggnadsteknik;

    Sammanfattning : Reduction of the cost of construction is a constant goal for the building industry. One way of reducing the construction cost of buildings is to develop building technologies that will give increased productivity. Reduced construction time at the building-site and waste of materials and resources contribute to furtherreduction of the costs. LÄS MER
