  1. 1. Energy efficiency and the challenge of climate change - Studies of the Swedish building sector

    Författare :Jonas Nässén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; technology diffusion; input-output analysis; Energy efficiency; Swedish building sector; carbon dioxide;

    Sammanfattning : The interrelated environmental, social and economic challenges imposed by global climate change will make it one of the central political issues in the coming century. Use of fossil fuels is the largest source of anthropogenic CO2 emissions and hence the transformation of the energy system plays a central role in the mitigation of future climate change. LÄS MER

  3. 2. An Approach Towards Sustainable Building

    Författare :Navid Gohardani; Folke Björk; Kjartan Gudmundsson; Göran Lindahl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainability; Built environment; Sustainable renovation; High-efficient insulation materials; Sweden Green Building Council; Vacuum Insulation Panels VIP ; Decision making; GreenBuilding; Early stage; Stakeholders; A Concept for promotion of sustainable retrofitting and renovation in Early Stages ACES ; Early Stage Primary Energy Estimation Tool ESPEET ;

    Sammanfattning : The motivation for development of energy efficiency and implementation of novel advanced materials applied in buildings can be traced to increasing energy costs in conjunction with an enhanced environmental awareness among people. This doctoral dissertation presents contributions towards sustainable building, where factors such as building technology, energy efficiency in buildings, workers' health issues during construction measures, and certain economic considerations for renovation of buildings have been considered.

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

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

    Sammanfattning : 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. LÄS MER

  5. 4. Towards Environmental Informatics for Building Stocks. A Conceptual Model for an Environmental Building Stock Information System for Sustainable Development - EBSIS

    Författare :Liane Thuvander; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building stock; information system; environmental system analysis; energy flows; building stock information system; material flows; environmental informatics; urban system analysis; environment; sustainable sevelopment;

    Sammanfattning : The Swedish building sector uses a considerable amount of all materials and all energy used in Sweden. Knowledge about the existing building stock, its impact on the environment related to the use of material and energy, however, is limited and target settings for environmental objectives and decision making are based on vague information.

  7. 5. The role of biobased building materials in the climate impacts of construction : Effects of increased use of biobased materials in the Swedish building sector

    Författare :Diego Peñaloza; Magnus Wålinder; Martin Erlandsson; Andreas Falk; Johanna Berlin; Dimitris Athanassiadis; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LCA; timber buildings; timber bridges; biobased building materials; dynamic LCA; climate change mitigation; building stock; scenario analysis; biogenic carbon; Byggvetenskap; Civil and Architectural Engineering;

    Sammanfattning : A significant share of the global climate change impacts can be attributed to the construction sector. One mitigation strategy is increasing the use of biobased materials. Life cycle assessment (LCA) has been used to demonstrate the benefits of this, but forest complexities create uncertainty due to omission of key aspects. LÄS MER
