  2. 1. Moisture Transport in Porous Media. Modelling Based on Kirchhoff Potentials

    Author : Jesper Arfvidsson; Avdelningen för Byggnadsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; moisture distribtion; wood drying; wood; diffusion coefficient; numerical modelling; moisture flow; Moisture; transient measurements; periodic boundary condition; penetration depth; sorption coefficient; non-linear moisture flow; calculation model; anisitropy; Kirchhoff potentials; evaluation; moisture transport; Building construction; Byggnadsteknik;

    Abstract : The work presented in this thesis is focused on the development of the new concept to describe isothermal moisture transport using Kirchhoff potentials. The first four papers deal with moisture transport in porous media using Kirchhoff potentials. The last three papers deal with wood. READ MORE

  5. 3. What have residents got to do with it? : Variations in energy use and energy-related behaviours in single-family houses

    Author : Carolina Hiller; Jesper Arfvidsson; Thorbjörn Laike; Avdelningen för Byggnadsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy use variations; energy-related behaviour; single-family houses; households; residents; multi-disciplinary; field measurements; times-use diaries; energy use over time; load curves; power peaks; energy measurements; residential houses;

    Abstract : To achieve global energy goals, energy use in residential buildings must decrease. The implementation of technical measures is crucial but alone it is not sufficient; residents need to change their behaviour as well. READ MORE

  6. 4. Simulation of historic buildings for enhancement of preservation and energy performance – issues and methods

    Author : Torun Widström; Folke Björk; Kjartan Gudmundsson; Jesper Arfvidsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building simulation; historic buildings; energy performance; damage risk; mould; thermal bridges; Byggvetenskap; Civil and Architectural Engineering;

    Abstract : Historic buildings are often particularly poorly insulated and difficult to heat, and are also at risk for several reasons. These include potential lack of use due to low thermal comfort leading to low or no profitability, damage risks due to over and under-climatization and risks due to climate change altering the boundary conditions that they were built for.

  7. 5. Managing Uncertainty in Environmental and Cost Life Cycle Studies of Building Design

    Author : Peter Ylmen; Jesper Arfvidsson; Kristina Mjörnell; Johanna Berlin; Tomas Ekvall; RISE; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building design; life cycle; LCA; LCC; uncertainties; method; Building design; life cycle; LCA; LCC; uncertainties; method;

    Abstract : In order to mitigate global warming and address other pertinent environmental issues, it is important to reduce the environmental impact from the building stock. Emissions can be large for both operational energy consumption and production of materials. READ MORE
