    Abstract : 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. READ MORE

  5. 3. Building Integration of Solar Energy. A Multifunctional Approach

    Author : Andreas Fieber; Avdelningen för Energi och byggnadsdesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis consists of two parts. The first part deals with building integrated solar energy, mainly from an architectural point of view. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 5. Heat conduction in two and three dimensions : computer modelling of building physics applications

    Author : Thomas Blomberg; Avdelningen för Byggnadsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; civil engineering; building physics; thermal radiation; numerical modelling; Heat conduction; computer programs;

    Abstract : The first aim of this doctoral work has been to develop a new generation of computer programs for transient and steady-state heat conduction in two and three dimensions. A large range of heat transfer problems within the field of buildings physics can be analyzed using these tools. READ MORE
