6. Towards molecular weight-dependent uses of kraft lignin
Sammanfattning : There is growing demand for a more efficient use of polymers that originate from renewable feedstocks due to the depleting supply of fossil fuels, based on economic and environmental reasons. As a result, lignin has attracted renewed interest as a resource for various bioproducts. LÄS MER
7. Transparent Wood Biocomposites for Sustainable Development
Sammanfattning : Sustainable wood nanotechnologies that combine optical transmittance and mechanical performance are interesting for new functionalities utilizing transparency. Wood is a sophisticated bio-based material with a natural hierarchical, anisotropic and porous structure. LÄS MER
8. Windows : Optical Performance and Energy Efficiency
Sammanfattning : This thesis treats angle-resolved optical properties and the energy efficiency of windows. A theoretical evaluation of optical and thermal properties of windows is briefly surveyed and the energy performance of a large selection of windows, under different conditions, is examined. In particular, angle dependent optical properties are analysed. LÄS MER
9. The ORC method
Sammanfattning : The ORC Method (Optimised RC-networks) provides a means ofmodelling one- or multidimensional heat transfer in buildingcomponents, in this context within building simulationenvironments. The methodology is shown, primarily applied toheat transfer in multilayer building components. LÄS MER
10. Optical Characterization and Energy Simulation of Glazing for High-Performance Windows
Sammanfattning : This thesis focuses on one important component of the energy system - the window. Windows are installed in buildings mainly to create visual contact with the surroundings and to let in daylight, and should also be heat and sound insulating. LÄS MER
