  2. 1. Direct Ground Cooling Systems for Office Buildings

    Author : Taha Arghand; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Ground heat exchangers; Energy renovation; Renewable energy; GeoTABS; Active chilled beams; Geocooling systems; TABS; ground-coupled cooling; Passive ground cooling; Thermal comfort; Direct ground cooling; Energy efficiency; Boreholes; Ceiling cooling panels; High-temperature cooling; Optimization; Comfort cooling;

    Abstract : The solving of crucial global energy challenges hinges on improving energy efficiency in building energy systems. Accomplishing energy-efficiency targets often entails incorporating sustainable energy sources into the energy supply system. READ MORE

  4. 2. Heat driven cooling in district energy systems

    Author : Magnus Rydstrand; KTH; []
    Keywords : District heating; district cooling; thermal storage; humidified gas turbines; combined heat and power; cooling;

    Abstract : Abstract The threat of global warming, caused by increasingemissions of carbon dioxide (CO2), is one reason why cooling supply systems mustwork more efficiently in the world today. An increasing share,currently between 10 and 20%, of the global output ofelectricity is consumed to produce cooling. READ MORE

  5. 3. Heating and Cooling Requirements in Commercial Buildings. A duration curve model including building dynamics

    Author : Per-Erik Nilsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVAC system; cooling requirements; duration curve; heating requirements; commercial building; heat balance; balance curve; energy analysis;

    Abstract : In many European countries, especially, the heat loss due to transmission and air leakage, in many buildings today, is only a fraction of what it was in those built in the early 70's. At the same time there have been changes in the way the buildings are used which, among other things, has lead to an often considerable increase of the internal heat loads. READ MORE

  6. 4. High-Temperature Cooling Systems for Sustainable Buildings Using Geothermal Energy : Holistic Assessment in the Mediterranean Climate

    Abstract : 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). READ MORE

  7. 5. Climate and Energy Use in Glazed Spaces

    Author : Maria Wall; Institutioner vid LTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; design tool; field measurements; calculations; thermal comfort; cooling; heating; energy requirement; solar energy; climate; atrium buildings; glazed spaces;

    Abstract : Glazed spaces ranging from small glazed verandas to large atrium buildings have become a common feature in architecture. A glazed space is greatly affected by aspects of the outside climate such as insolation and temperature. READ MORE
