  2. 6. Convection in Loose-fill Attic Insulation

    Author : Paula Wahlgren; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; loose-fill insulation; forced convection; attics; natural convection; heat transfer; thermal insulation;

    Abstract : The objective of this study is to investigate the influence of convection on the thermal performance of loose-fill attic insulation under realistic climate conditions. In order to achieve this, a large-scale attic test model has been constructed in a climate chamber. READ MORE

    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. 8. Insulation materials in district heating pipes : Environmental and thermal performance of polyethylene terephthalate and polyurethane foam

    Author : Sara Mangs; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; HFC-365mfc; insulation; District heating pipe; 3-pentafluorobutane; cyclopentane; 3; 1; mass transport; 1; 1; thermal performance; polyurethane foam; polyethylene terephthtalate foam;

    Abstract : District heating can contribute to increased energy efficiency in society. The environmental impact can be reduced by minimising the heat losses in the district heating pipes during distribution of the heat to the customers. READ MORE

  6. 9. Cellulosic Thermal Insulation with Improved Water Resistance and Fire Retardancy

    Author : Chao Zheng; Monica Ek; Dongfang Li; Lennart Salmén; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Bio-based; Cellulosic; Fire retardant; Thermal insulation; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Abstract : Sweden is one of the largest countries by area in Europe, and almost 70% of it is covered by forest. These abundant forest resources benefit the Swedish bioeconomy, but the pulp and paper industry is facing the challenge of a decrease in the demand for printing paper due to a significant shift to electronic media; therefore, it is a priority to use pulp to produce alternative value-added products, such as thermal insulating materials in buildings.

  7. 10. Environmental and Thermal Performance of District Heating Pipes

    Author : Morgan Fröling; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heat distribution; cyclopentane; district heating pipe; long-term thermal performance; life cycle assessment; insulation; polyurethane foam; environmental performance; carbon dioxide; HFC-365mfc;

    Abstract : In order to move towards a sustainable society we need to increase the efficiency of our use of available resources, not only in economic terms but also in ecological terms. District heating, the utilisation of centrally produced heat for space heating and domestic hot water generation, has the potential to contribute to the eco-efficient use of energy resources in the parts of the world where space heating is needed.
