  1. 16. An evaluation of regional sustainability by analysing energy and carbon flows – A study of Jämtland, Sweden

    Författare :Torbjörn Skytt; Bengt-Gunnar Jonsson; Fredrik Ståhl; Magdalena Svanström; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Regional sustainability; Energy flows; Exergy; Carbon GHG fluxes; Sustainability indicators; carbon dioxide emissions; methane emissions; nature emissions;

    Sammanfattning : Models showing the anthropogenic and natural flows of two sustainability indicators; carbon based GHG and energy (as work energy) have been made for the Swedish region Jämtland. The methodology used was inspired by the study sustainability analysis conducted on the small Danish island Samsø using the above two indicators. LÄS MER

  3. 17. Exergy and Parametric Analysis: Methods and Concepts for a Sustainable Built Environment

    Författare :Marco Molinari; Folke Björk; Gudni Johannesson; Bjarne W. Olesen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Energy use in the world is continuously increasing. In the last 30 years the use of primary energy worldwide has more than doubled and it is mainly supplied with fossil fuels. A more efficient use of energy in the built environment has to be pursued if a more sustainable development is to be attained. LÄS MER

  4. 18. Environmental Systems Analysis of Wastewater Management

    Författare :Erik Kärrman; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The history of wastewater management tells us that efforts have been made at solving only one problem at the time; sanitation during the first half of the 20th Century followed by eutrophication of lakes and sea and, for the past ten years, recycling of nutrients. After the "Brundtland Report", 1987, a reversal of the debate occurred where water management was discussed in a more holistic manner than before. LÄS MER

  5. 19. An analysis of architectural and urban planning strategies for developing energy efficient cities in China

    Författare :Zhenhong Gu; Fredrik Gröndahl; Dong Wei; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Energy efficiency; Nanjing; China; urban planning; passive house; low exergy system; Building Environmental Assessment; LCA; Swedish housing; Hammarby Sjöstad; eco-village; game theory; systems theory; soft systems methodology; Industrial Ecology; Industriell ekologi;

    Sammanfattning : This thesis presents a detailed analysis of architecture and urban planning strategies for developingenergy-efficient cities in a Chinese context. The overall aim of the work is to examine how Chineseurbanisation and city construction can be improved from an energy-saving perspective. LÄS MER

  7. 20. Modelling, analysis and optimisation of ship energy systems

    Författare :Francesco Baldi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Shipping is the backbone of today's economy, as 90% of global trade volumes is transported by sea. Much of our lifestyle today is only made possible by the existence of shipping as a cheap and reliable mean of transportation across the globe. LÄS MER
