  1. 6. Energy renovation of multi-family buildings in Sweden : An evaluation of life cycle costs, indoor environment and primary energy use, and a comparison with constructing a new building

    Författare :Lina La Fleur; Bahram Moshfegh; Patrik Rohdin; Andreas Koch; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Residential buildings account for 27% of the final energy use in the European Union. In cold climates, space heating represents the largest proportion of the energy demand in residential buildings. By implementing energy efficiency measures (EEMs) in existing buildings, energy use can be significantly reduced. LÄS MER

  3. 7. Combined production of edible mushrooms and biofuels from lignocellulosic residues

    Författare :Feng Chen; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Forest residues, wood-processing by-products and other lignocellulosic materials are promising renewable resources for bioconversion to advanced biofuels such as cellulosic ethanol. Increased production of biofuels from lignocellulosic materials would allow reducing environmental problems caused by the use of fossil resources while supporting development of bioeconomy. LÄS MER

  4. 8. Towards sustainability with building services systems : – by focusing on material choices, energy use and thermal indoor climates in residential buildings

    Författare :Mats Dahlblom; Avdelningen för Installations- och klimatiseringslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; residential apartment buildings; building services systems; energy use; hvac; hydronic heating system; heating control; feedback control loop; indoor temperature measurements; individual metering and billing; indoor temperature variations; thermal comfort; vertical temperature gradient; case study;

    Sammanfattning : For a development to be considered sustainable, social, economic and environmental requirements must be met. The Swedish sustainable development goals, based on Agenda 2030, contain 16 national environmental quality goals. The National Board of Housing, Building and Planning is responsible for achieving the goal "A good built environment". LÄS MER

  5. 9. Exergy Analysis in Buildings : A complementary approach to energy analysis

    Författare :Marco Molinari; Folke Björk; Gudni Jóhannesson; Ivo Martinac; KTH; []
    Nyckelord :Exergy; Energy; Building systems performance; Built environment.;

    Sammanfattning : Though mandatory to be pursued, improved energy efficiency is not the only target to reach. The quality of energy has to be assessed as well. Most of the overall energy use in residential building is for low temperature heat, i.e. LÄS MER
