  1. 1. Energy Harvesting and Energy Storage for Wireless and Less-Wired Sensors in Harsh Environments

    Författare :Elof Köhler; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Piezoelectric; coupled harvester; Thermoelectric; harsh environment; piezoelectric harvester; Energy harvester; supercapacitor; Thermoelectric harvester;

    Sammanfattning : Engineering requires sensors to control and understand the environment. This is particularly important in harsh environments. The drawbacks, especially in gas turbines is the complexity of installing a wired sensor and the weight of the wires. This makes wireless sensors attractive. LÄS MER

  3. 2. 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. Micro-grids supplied by renewable energy : Improving technical and social feasibility

    Författare :Caroline Bastholm; Ewa Wäckelgård; Annette Henning; Frank Fiedler; Kirsten Ulsrud; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rural electrification; Electricity access; Decentralized; Off-grid; Photovoltacs; PV-hybrid; Micro-grid; Multi-disciplinary; Sociotechnical; Engineering Science; Teknisk fysik; Energy and Built Environments;

    Sammanfattning : Universal access to electricity stands high on the global agenda and is regarded as essential for positive development in sectors such as health care, education, poverty reduction, food production and climate change. Decentralized, off-grid electrification is deemed an important complement to centralized grid extension. LÄS MER

  5. 4. Simple Question, Complex Answer : Pathways Towards a 50% Decrease in Building Energy Use

    Författare :Philipp Weiss; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Buildings; Regional energy policy; Energy efficiency; Rebound effect; Community-Based Social Marketing; Teknisk fysik; Engineering Science; Energy and Built Environments;

    Sammanfattning : Addressing building energy use is a pressing issue for building sector decisionmakers across Europe. In Sweden, some regions have adopted a target of reducingenergy use in buildings by 50% until 2050. LÄS MER

  7. 5. Omställning – Tillväxt – Effektivisering : Energifrågor vid renovering av flerbostadshus

    Författare :Josefin Thoresson; Kajsa Ellegård; Wiktoria Glad; Örjan Svane; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Building refurbishment; apartment buildings; energy assemblages; urban energy transition; energy efficiency; STS; urban assemblages; built environments; translations; energy goals; Energieffektivisering; byggnadsrenovering; flerbostadshus; energisammansättning; urban energiomställning; STS; byggda miljöer; energimål; översättning;

    Sammanfattning : Flerbostadshus anses viktiga för att minska energianvändningen i byggnader, och potentialen att energieffektivisera i samband med renovering är stor. Denna studie behandlar hur arbete med energifrågor genomförs i renovering av flerbostadshus byggda under miljonprogrammet i stadsdelen Östra Sätra i Gävle. LÄS MER
