  1. 11. 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

    Sammanfattning : Transactional Memory (TM) is an emerging programming paradigm that drastically simplifies the development of concurrent applications by relieving programmers from a major source of complexity: how to ensure correct, yet efficient, synchronization of concurrent accesses to shared memory. Despite the large body of research devoted to this area, existing TM systems still suffer from severe limitations that hamper both their performance and energy efficiency. LÄS MER

  4. 13. Energy Efficiency in buildings in the Baltic states and the Nordic countries

    Författare :Xiaoying Li; Jonas Björnerstedt; Mats Bergman; Xiang Lin; Robert Lundmark; Södertörns högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; energy efficiency; building regulation; multi-apartment buildings; retrofit; energy performance gap; housing management; energy price inflation; inflation expectations; energieffektivitet; byggreglering; flerbostadshus; renovering; energiprestandagap; bostadsförvaltning; energiprisinflation; inflationsförväntningar; Politics; Economy and the Organization of Society; Politik; ekonomi och samhällets organisering; Östersjö- och Östeuropaforskning; Baltic and East European studies;

    Sammanfattning : Improving energy efficiency in buildings is widely viewed as a cost-effective way of achieving climate and energy goals. The Energy Performance of Buildings Directive (EPBD) aims to enhance the energy performance of new buildings and increase the renovation rate of energy-inefficient older buildings in the European Union.

  5. 14. Building Energy Efficiency Measures in District Heating Systems

    Författare :Tina Lidberg; Louise Ödlund; Thomas Olofsson; Erik Dahlquist; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building simulation; combined heat and power; district heating; domestic hot water; energy efficiency; greenhouse gas emission; low-temperature; multi-family building; primary energy; refurbishment; byggnadsimulering; energieffektivitet; flerfamiljshus; fjärrvärme; kraftvärme; lågtemperatur; primärenergi; renovering; tappvarmvatten; växthusgas; Hållbar stadsutveckling; Sustainable Urban Development; Reesbe företagsforskarskola;

    Sammanfattning : Improving energy performance of existing buildings is an important part in decreasing energy use and in turn reducing greenhouse gas emissions and primary energy use. To be able to evaluate how energy refurbishment influences greenhouse gas emissions and primary energy use a wider system perspective is needed which puts the building in its context. LÄS MER
