  1. 1. Energy Efficient Renovation Strategies for Swedish and Other European Residential and Office Buildings

    Författare :Marcus Gustafsson; Sture Holmberg; Jonn Are Myhren; Chris Bales; Jarek Kurnitski; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; renovation; low-temperature heating; air heat recovery; district heating; heat pump; Energieffektivitet; renovering; lågtemperaturuppvärmning; värmeåtervinning; fjärrvärme; värmepump; Byggvetenskap; Civil and Architectural Engineering; Energy and Built Environments;

    Sammanfattning : The high energy use in the European building stock is attributable to the large share of old buildings with poor energy performance. Energy renovation of buildings is therefore vital in the work towards energy efficiency and reduced environmental impact in the EU. LÄS MER

  4. 3. Tappvattenvärmning med värmepump. Krav och erfarenheter

    Författare :Jessica Benson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system solutions; measurements; Heat pump; hot water;

    Sammanfattning : This licentiate thesis deals with system solutions for heat pump hot water heating inSweden. Hot water heating requires higher temperatures than space heating and thereforelowers the annual performance of the heat pump system. In existing single family houses,space heating represents the majority of heat pump delivered energy. LÄS MER

  5. 4. A System Perspective on Energy End-Use Measures in a District Heated Region : Renovation of Buildings and Hydronic Pavement Systems

    Författare :Stefan Blomqvist; Louise Ödlund; Patrik Rohdin; Jan Akander; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : A district heating and cooling (DHC) system can be a viable piece of the puzzle in the efforts of reducing the greenhouse gas (GHG) emissions. Especially if the DHC system include combined heat and power (CHP) plants which enable electricity production from renewable resources. LÄS MER

  7. 5. Fysiken spelar roll! : Undervisning om hållbara energisystem, fokus på gymnasiekursen fysik A

    Författare :Susanne Engström; Peter Gustafsson; Hans Niedderer; Erik Dahlqvist; Stellan Löfdahl; Mälardalens högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Physics teaching; sustainable energy education; Fysikundervisning; undervisning om hållbar energi; Pedgogical work; Pedagogiskt arbete; Naturvetenskapernas och teknikens didaktik;

    Sammanfattning : This thesis will present the result from one main investigation (step 1) and two follow-up studies (step 2 and 3). The main study consists of an interpreting, iterative analysis of statements made by ‘experts’ on contents of education gathered from a questionnaire, which result in a subject-specific content for physics education on sustainable energy systems (SES) presented as a category system.
