  1. 6. Improved building energy simulations and verifications by regression

    Författare :Jimmy Vesterberg; Thomas Olofsson; Folke Björk; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calibrated simulations; Energy signature; Regression; BES; IDA ICE; Multifamily buildings; EUI;

    Sammanfattning : It is common with significant differences between calculated and actual energy use in the building sector. These calculations are often performed with whole building energy simulation (BES) programs. In this process the analyst must make several assumptions about the studied building and its users.

  3. 7. Solar Shading for Low Energy Use and Daylight Quality in Offices: Simulations, Measurements and Design Tools

    Författare :Marie-Claude Dubois; Avdelningen för Energi och byggnadsdesign; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; screens; venetian blinds; awnings; design tools; measurements; computer simulations; solar-protective glass; heating; cooling; visual comfort; daylighting; energy use; Shading devices; solar protection; Architecture; interior design; Arkitektur; inredningsarkitektur; Energy research; Energiforskning;

    Sammanfattning : This thesis investigates the impact of solar shading devices on energy use and daylight quality in office rooms. The impact on energy use is analysed through computer simulations with the dynamic energy simulation program Derob-LTH while the impact on daylight quality is investigated through measurements in full-scale experimental office rooms and simulations with the program Radiance.

    Författare :Ricardo Ramirez Villegas; Ola Eriksson; Thomas Olofsson; Harpa Birgisdottir; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Buildings; renovation; greenhouse gas emissions; district heating; energy efficiency; building environmental assessment tools; energy use; space heating; life cycle assessment; life cycle costing; payback; scenarios simulation; Byggnadsrenovering; växthusgasutsläpp; fjärrvärme; energieffektivitet; system för miljöcertifiering av byggnader; energianvändning; byggnadsuppvärmning; livscykelanalys; livscykelkostnader; återbetalning; scenariosimulering; Hållbar stadsutveckling; Sustainable Urban Development; Reesbe företagsforskarskola;

    Sammanfattning : Energy use in the European Union is increasing. At the same time, it is estimated that by the year 2050 most of the EU population will be living in currently existing buildings. Some of these buildings are or will be in need of renovation, and they have identified a target to reduce overall energy use. LÄS MER

  5. 9. Single and Double Skin Glazed Office Buildings - Analyses of Energy Use and Indoor Climate

    Författare :Harris Poirazis; Avdelningen för Energi och byggnadsdesign; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal environment; indoor climate; energy use; building performance; building simulations; double skin façades; Glazed office buildings; single skin façades; thermal comfort;

    Sammanfattning : The energy efficiency and thermal performance of highly glazed office buildings are often questioned. However, nowadays glazed buildings are increasingly being built around the world, mainly due to an architectural trend, followed by the preference of companies to a distinctive image that a glazed office building can provide.

  7. 10. Evaluating energy efficient buildings : Energy- and moisture performance considering future climate change

    Författare :Björn Berggren; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Net Zero Energy Building; passive house; thermal bridge; building envelope; energy performance; moisture performance; multi criteria decision making; climate change; climate scenarios; EN ISO 13789; EN ISO 10211;

    Sammanfattning : One of the greatest challenges the world is facing is climate change. The need of reduction of energy use and an increased use of renewable energy in buildings constitutes important climate change mitigation measures. LÄS MER
