  2. 6. Evaluation of new active technology for low-energy houses

    Author : Henrik Davidsson; Avdelningen för Energi och byggnadsdesign; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-quality heat; hybrid ventilation; heat recovery; active house; solar window; PV T hybrid; building integration; TRNSYS;

    Abstract : Using energy at low-quality levels opens up new possibilities for low-energy houses. Low-quality energy can be heat at a temperature that is close to that of its surrounding, and can be used, for example, to pre-heat ventilation air or domestic hot water. READ MORE

  4. 7. Energy systems analysis of Swedish pulp and paper industries from a regional cooperation perspective : Case study modeling and optimization

    Author : Sofia Klugman; Bahram Moshfegh; Thore Berntsson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial energy system; Optimization; District heating; Energy audit; Co-operation; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The industrial sector uses about one third of the energy end-use in the world. Since energy use in many cases highly affects both the local and global environment negatively, it is of common interest to increase energy efficiency within industries. READ MORE

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Demand Response; Flexible loads; Building stock energy-use; Bottom-up simulation models; Load profiles; Non-homogeneous Markov-chains; End-user behavior; Lumped capacitance models; HVAC system control; Smart Grid.; Efterfrågeflexibilitet; Flexibla laster; Energianvändning i byggnadsstocken; Botten-upp-simuleringsmodeller; Elförbrukningsprofiler; Icke-homogena Markovkedjor; Slutanvändarbeteenden; Värmedynamikmodellering; Styrning av HVAC-laster; Smarta elnät.;

    Abstract : The electric power systems are currently being transformed through the integration of intermittent renewable energy resources and new types of electric loads. These developments run the risk of increasing mismatches between electricity supply and demand, and may cause non-favorable utilization rates of some power system components. READ MORE

  6. 9. To analyse measurements is to know!

    Author : Henrik Gadd; Institutionen för energivetenskaper; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; Hourly meter readings; fault detection; Low return temperature; temperature difference.;

    Abstract : Renewable energy sources dominated the world energy supply until the beginning of the 20th century, when fossil energy became the dominant energy source worldwide. Today, fossil fuels contribute to over 80% of world energy supply. But there are two major reasons why fossil energy use has to stop. READ MORE
