  2. 21. Building Energy Efficiency Measures in District Heating Systems

    Author : Tina Lidberg; Louise Ödlund; Thomas Olofsson; Erik Dahlquist; Högskolan i Gävle; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 22. Energy performance of multifamily buildings : building characteristic and user influence

    Author : Jan-Ulric Sjögren; Thomas Olofsson; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy performance; total heat loss coefficient; gain factor; benchmarking; parameter influence; multivariate method; Building engineering; Byggnadsteknik;

    Abstract : Today many professional property holders use different types of software for monthly energy analyses. The data is however often limited to energy and water use, that is paid for by the property holder. In year 2001, financed by the Swedish Energy Agency, the first steps were taken to create a national web based data base, eNyckeln. READ MORE

  5. 23. Heat demand profiles of buildings' energy conservation measures and their impact on renewable and resource efficient district heating systems

    Author : Lukas Lundström; Erik Dahlquist; Fredrik Wallin; Björn Karlsson; Jan Akander; Sven Werner; Mälardalens högskola; []

    Abstract : Increased energy performance of the building stock of European Union is seen as an important measure towards mitigating climate change, increasing resource utilisation efficiency and energy supply security. Whether to improve the supply-side, the demand-side or both is an open issue. READ MORE

    Abstract : In Sweden, buildings are responsible for about 40 % of total energy use and about 10 % of total CO2 emissions Today more than 60 % of existing Swedish residential buildings are over 40 years old and are in need of major renovation. In addition, 15 % of all multi-family buildings and 27 % of all single-family houses were built before 1945. READ MORE

  7. 25. Gothenburg District Cooling System - An evaluation of the system performance based on operational data

    Author : Maria Jangsten; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building chilled water systems; district cooling; high temperature district cooling; low delta-T;

    Abstract : The global energy demand for providing cooling in buildings is expected to increase the next decades, along with a rapid growth in the number of air conditioners and chillers. A more energy efficient, economical and environmentally viable solution to this increased cooling demand, is district cooling. READ MORE
