  2. 1. 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

  4. 2. Optimization of ground-coupled systems for heating and cooling of buildings

    Author : Jüri Naumov; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; free-cooling; brine temperature; heat pump; ground system; heating demand; storage; building load; cooling demand; Borehole;

    Abstract : The use of ground-coupled systems in commercial buildings offers economic as well as environmental advantages. When both heating and cooling is required, a ground-coupled system can function both as a heat source and a heat sink. At the same time, it can also serve as a short term as well as a seasonal storage. READ MORE

  5. 3. 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

  6. 4. Energy efficiency in shopping malls. Energy use and indoor climate

    Author : Sofia Stensson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy use; loads; cooling; Shopping mall; simulation; heating; field measurements;

    Abstract : The purpose of this licentiate thesis is to describe energy use, heating and cooling demands and the relative importance of internal heat loads in shopping malls. It will be a foundation for a future doctorial thesis in which alternative energy efficient HVAC systems for shopping malls will be analysed. READ MORE

  7. 5. Solar Shading for Low Energy Use and Daylight Quality in Offices: Simulations, Measurements and Design Tools

    Author : Marie-Claude Dubois; Avdelningen för Energi och byggnadsdesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building construction; screens; venetian blinds; awnings; design tools; measurements; computer simulations; solar-protective glass; heating; cooling; visual comfort; daylighting; energy use; Shading devices; solar protection; Architecture; interior design; Arkitektur; inredningsarkitektur; Energy research; Energiforskning;

    Abstract : This thesis investigates the impact of solar shading devices on energy use and daylight quality in office rooms. The impact on energy use is analysed through computer simulations with the dynamic energy simulation program Derob-LTH while the impact on daylight quality is investigated through measurements in full-scale experimental office rooms and simulations with the program Radiance.
