  1. 31. Documentation and Maintenance Planning Model – DoMaP A response to the need for conservation and long-term maintenance of façades of modern multi-apartment buildings Based on case studies in Göteborg in Sweden

    Författare :Pär Meiling; Chalmers tekniska högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; public housing companies; façade-materials; Sustainable integrated conservation; long-term maintenance operations; deterioration; optical measurement techniques; generic multi-apartment buildings;

    Sammanfattning : Sustainable maintenance and renovation of façades on generic multi-apartment buildings from late 1950s through 70s constitute vital challenges for the housing companies owned by City of Göteborg. These challenges comprise a wide array of issues, such as deterioration and damages in occurring façade materials, status assessments, technical improvements, reduction of energy consumption, and up-keeping of housing qualities and tenants attraction.

  3. 32. Energy demand management in selected African countries

    Författare :Philip Kofi Adom; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : This thesis contains five empirical papers that contribute to the energy demand management literature on Africa. It investigates the following policy issues – business cycle and energy conservation, government fuel subsidies and energy efficiency, economic growth and environmental quality, structural effects in parameters, the transition between energy efficiency and energy inefficiency, forecast of energy demand, shifts in demand behaviour, and the persistence profile of energy demand to shocks – using data from five countries: Algeria, Nigeria, South Africa, Cameroon and Ghana.

    Sammanfattning : Developments in machine design play a crucial role in the global endeavor towards sustainability. The potential for energy conservation and emission reduction has pushed lubrication research to the forefront, with the lubricant considered to be a vital machine component. LÄS MER

  5. 34. Optical Design and Characterization of Solar Concentrators for Photovoltaics

    Författare :Johan Nilsson; Avdelningen för Energi och byggnadsdesign; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Stationary solar energy concentrators are a promising option for decreasing the price of photovoltaic electricity. This thesis studies stationary concentrators in PV/Thermal applications. The studied systems are parabolic troughs intended for building integration. The first chapters briefly explain the optics of solar energy concentrators. LÄS MER

  7. 35. Swedish district heating systems and a harmonised European energy market : means to reduce global carbon emissions

    Författare :Jörgen Sjödin; Sven Werner; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Energy systems in Europe are becoming more harmonised and the European Union is working to establish a single market for energy. In this thesis, it is therefore regarded as a system failing to consider a separate and isolated Swedish energy system. Extending the system boundaries enables increased resource efficiency. LÄS MER
