  1. 1. 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

  3. 2. Distributed wireless control strategies for district heating substations

    Författare :Jonas Gustafsson; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : The overall fuel efficiency of district heating could clearly be improved by using new strategies for measurement and control. The potential for improvement is on the order of several percent. LÄS MER

  4. 3. Building Sustainability : Studies on incentives in construction and management of real estate

    Författare :Lovisa Högberg; Hans Lind; Tina Karrbom Gustavsson; Marja Elsinga; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; sustainability; sustainable buildings; sustainable renovation; sustainable construction; sustainable management; housing; sustainable building certification; energy efficiency; incentives; Fastigheter och byggande; Real Estate and Construction Management;

    Sammanfattning : This thesis summarizes the results from several studies with connection to sustainability in construction and management of real estate. Here, the concept sustainability includes environmental, social and economic dimensions and focus is on the actors with the best possibilities to impact real estate, namely the real estate owners and the developers.

  5. 4. Improved energy efficiency in double disc chip refining

    Författare :Dino Muhic; Per Engstrand; Lars Sundström; Mats Ullmar; Christer Sandberg; Hans Höglund; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermomechanical pulping TMP ; double disc refining; high intensity; Chemical engineering; Kemiteknik;

    Sammanfattning : The electrical energy consumption in thermomechanical pulping (TMP) is very high, in the range of 2 – 3 MWh/adt depending on process solution and on the product quality specifications for the paper product. Both pulpwood and energy prices have increased rapidly for some time. LÄS MER

  7. 5. Re-viewing industrial energy-efficiency improvement using a widened system boundary

    Författare :Svetlana Paramonova; Patrik Thollander; Mats Söderström; Stefan Grönkvist; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Improved energy efficiency in industry is important for reaching the targets within the EU strategy for increased sustainability. However, energy efficiency is not always prioritised within companies, and the improvement potential remains large. This paradox called an energyefficiency gap is explained by energy-efficiency barriers. LÄS MER
