  2. 1. System Expansion and Allocation in Life Cycle Assessment With Implications for Wastepaper Management

    Author : Tomas Ekvall; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; paper recycling; waste incineration; environmental life cycle assessment; LCI methodology; allocation; waste management; system expansion; system boundaries; life cycle inventory analysis;

    Abstract : The choice of system boundaries and allocation methods can have decisive effects on the results and conclusions of a life cycle assessment (LCA). System expansion makes it possible to model the indirect effects of a decision; however, this modelling is often based on inaccurate assumptions. READ MORE

  4. 2. Heating of buildings from a system perspective

    Author : Moa Swing Gustafsson; Erik Dotzauer; Jonn Are Myhren; Tomas Ekvall; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik; Reesbe företagsforskarskola;

    Abstract : Energy efficiency measures in buildings are considered to have great potential for reducing total energy use, and contribute to a reduced climate and environmental impact. In Sweden, however, there is a focus on bought energy, which does not always reflect the environmental and climate impact. READ MORE

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