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

    Författare :Björn Mattsson; Chalmers tekniska högskola; []
    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

  3. 17. Evaluating building envelopes for energy efficient buildings : Energy- and moisture performance considering future climate change

    Författare :Björn Berggren; Avdelningen för Energi och byggnadsdesign; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Buildings account for a signifi cant proportion of the energy use thatgenerates greenhouse gases and consequently drives the ongoing climatechange. As the population of the world increases, the need for buildingsincreases, while the energy use needs to decrease. LÄS MER

  4. 18. Modelling Energy Conservation and CO2 Mitigation in the European Building Stock

    Författare :Erika Mata Las Heras; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cost assessment; bottom-up building modelling; techno-economical potentials; archetype building; energy conservation measures; European building stock;

    Sammanfattning : This thesis investigates energy conservation in building stocks with the aim of developing a methodology that can be applied to the national building stocks of the European Union (EU). For this purpose, a bottom-up building-stock model and a methodology for describing the building-stock have been established. LÄS MER

  5. 19. Assessment and optimization of life cycle enrgy use in buildings

    Författare :Farshid Shadram; Thomas Olofsson; Holger Wallbaum; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggproduktion och teknik; Construction Management and Building Technology;

    Sammanfattning : Buildings account for 40% of all energy use in European countries. The European Union (EU) therefore encourages member states to adopt Energy Efficiency Measures (EEMs) and implement energy-efficient practices during building design to minimize the energy use of buildings.

  7. 20. Energy efficiency strategies for residential buildings in a subarctic climate: Impacts on energy use and indoor thermal climate

    Författare :Shimantika Bhattacharjee; Lars Stehn; Sofia Lidelöw; Thomas Olofsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggproduktion och teknik; Construction Management and Building Technology;

    Sammanfattning : Adopting energy efficiency strategies in residential buildings are beneficial as these not only improve the energy performance but also improves the indoor thermal climate and minimizes the greenhouse gas emissions. There exist numerous studies on energy efficiency strategies and their influence on indoor thermal climate in residential buildings in cold climates. LÄS MER
