  1. 31. Lighting Control Systems for Energy Saving and User Acceptance: State-of-the-art and future directions

    Författare :Niko Gentile; Institutionen för arkitektur och byggd miljö; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Indoor lighting; lighting control system; lighting control; energy saving; energy efficiency; user acceptance; human factor; occupancy strategies; absence sensor; presence sensor; lighting switch; manual switch; daylight harvesting system; daylight-linked system; photoelectric dimming; photosensor.;

    Sammanfattning : Lighting accounts for one-fifth of global electricity use. In Sweden, energy demand for lighting corresponds to 20% of the total electricity use in office buildings. Lighting retrofit measures are considered to be among the most cost-efficient way to reduce energy use in buildings. LÄS MER

  3. 32. Improved Energy Efficiency in the Aluminium Industry and its Supply Chains

    Författare :Joakim Haraldsson; Magnus Karlsson; Maria Johansson; Max Åhman; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Energy is an essential resource in the daily lives of humans. However, the extraction and use of energy has an impact on the environment. The industrial sector accounts for a large share of the global final energy use and greenhouse gas (GHG) emissions. The largest source of industrial GHG emissions is energy use. LÄS MER

  4. 33. Passive Houses in Sweden. From Design to Evaluation of Four Demonstration Projects

    Författare :Ulla Janson; Avdelningen för Energi och byggnadsdesign; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Planning process; Energy efficiency; Passive house; Buildingconstruction; Residential buildings; Ventilation;

    Sammanfattning : The use of energy is a major global issue both according to climate changes but also in the aspect of national safety tied to the trade with energy sources. Of the total energy use in the member states of the European Union, about 40% is used in residential and commercial buildings. LÄS MER

  5. 34. Smart Cities and Climate Targets : Reducing cities' energy use with ICT and travel information

    Författare :Anna Kramers; Mattias Höjer; Åsa Svenfelt; Anders Gullberg; Frans Berkhout; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : This thesis examines use of ICT in helping to reduce energy use in cities, thereby contributing to sustainable development and achievement of cities’ climate targets. It explores how targets can be developed in a consistent and transparent way, how to identify the main ICT ‘hotspots’ as regards reducing citizens’ energy use and how they can be included in city planning.
