  1. 1. Behavior Change Towards a Sustainable Lifestyle – Effects of Interventions and Psychological Factors on Pro-Environmental Behaviors

    Författare :Kerstin Weimer; Richard Ahlström; Francisco Esteves; Tommy Gärling; Mittuniversitetet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; values; attitudes; moral judgment competence; locus of control; sense of coherence; pro-environmental behavior; energy conservation; feedback; Relational Frame Theory; motives and barriers to behavior change; food consumption; organically produced food; nudging; värderingar; attityder; moralisk bedömningskompetens; kontroll-lokus; känsla av sammanhang; miljövänligt beteende; energibesparing; feedback; Relational Frame Theory; motiv och hinder för beteendeförändring; matkonsumtion; ekologiskt odlad mat; nudging;

    Sammanfattning : Climate changes due to human-caused global warming are serious challenges for the planet. Changes in individual human behavior towards more pro-environmental actions are thus highly necessary. Human behavior is complex, however, and promoting behavior change requires a solid understanding of how people behave in different situations and contexts. LÄS MER

  3. 2. Energy Efficiency through Thermal Energy Storage : Possibilities for the Swedish Building Stock

    Författare :Johan Heier; Viktoria Martin; Chris Bales; Signhild Gehlin; Högskolan Dalarna; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal energy storage; buildings; energy efficiency; energy savings; peak load reduction; Swedish building stock; termisk energilagring; byggnader; energieffektivisering; energibesparing; toppbelastningsutjämning; Sveriges byggnadsbestånd; Värmelagring i byggnader;

    Sammanfattning : The need for heating and cooling in buildings constitutes a considerable part of the total energy use in a country and reducing this need is of outmost importance in order to reach national and international goals for reducing energy use and emissions. One important way of reaching these goals is to increase the proportion of renewable energy used for heating and cooling of buildings. LÄS MER

    Sammanfattning : 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. LÄS MER
