    Författare :Henrikki Pieskä; Johan Silfwerbrand; Adnan Ploskic; Qian Wang; Sture Holmberg; Sasan Sadrizadeh; Ambrose Dodoo; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radiant cooling; Geothermal cooling; Energy efficiency; Thermal comfort; Sustainable development; Strålningskylsystem; Geotermisk kyla; Energieffektivitet; Termisk komfort; Hållbar utväckling; Strömnings- och klimatteori; Fluid and Climate Theory;

    Sammanfattning : Sustainable development is increasing its significance in both the scientific and political agenda. In light of this development, the United Nations have published 17 Sustainable development goals (SDGs). LÄS MER

  3. 2. On the impact of temperature perturbations on the creep of sensitive clay

    Författare :Yanling Li; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; thermal cycles; sensitive clays; oedometer tests; temperature; natural bonding; apparent preconsolidation pressure; multi-physics modelling; geothermal; static thermal loading;

    Sammanfattning : Temperature affects the soil response, but is not fully understood and quantified and thus often ignored. The temperature fluctuations resulting from energy foundations and construction activities, such as excavations and soil stabilization, however, may lead to changes in the hydromechanical response of the clay.

  4. 3. Performance evaluations of high-temperature cooling systems in Mediterranean climate

    Författare :Henrikki Pieskä; Christophe Duwig; Saqib Javed; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; High-temperature cooling; building energy simulations; exergy; Högtemperaturkyla; byggnadsenergisimuleringar; exergi; Strömnings- och klimatteori; Fluid and Climate Theory;

    Sammanfattning : Cooling demand in Europe is predicted to grow 25-50% between 2020-2050. Meanwhile, the EU aims to lower the greenhouse gas emissions from its building stock by 60%. Therefore, it is essential to find solutions that can meet the growing cooling demand with less energy and integrate renewable energy sources. LÄS MER

  5. 4. Novel and ancient technologies for heating and cooling buildings

    Författare :Sofiane Amara; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vattenteknik; Water Resources Engineering;

    Sammanfattning : The basic issue of this thesis concerns one of the fundamental problems of the future of our society: How to meet the energy requirements for a large and growing world population while preserving our environment? This question is important for the world and the answers are complex and interwoven.Conventional energy sources, fossil and fissile, are polluting in the present and in the future: they erode the environment and their resources are limited.

  7. 5. District heating and cooling systems transition : Evaluation of current challenges and future possibilities

    Författare :Marwan Abugabbara; Avdelningen för Installations- och klimatiseringslära; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-domain modelling; Modelica; Heat pumps; 5GDHC; BLTN; Validation;

    Sammanfattning : District heating and cooling systems offer a cost-effective and secure supply of heating and cooling to connected buildings. They are widely recognised as a key solution to decarbonise the building sector due to their high potential of integrating renewable energy sources. LÄS MER
