  2. 11. Thermal comfort and energy in residential buildings in a cold climate

    Author : Petter Lundqvist; Mikael Risberg; Erik Elfgren; Patrik Rohdin; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : Building design typically has a focus on energy use and economy. The indoor environment is often overlooked or simplified to such an extent that essential aspects are neglected. Additionally, introducing technologies for improving energy efficiency can also affect the indoor thermal climate and, in turn, the perceived indoor comfort. READ MORE

  4. 12. Energy in supermarkets - An overview on the energy flows and refrigeration controls

    Author : Tommie Månsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : The electrical energy used by supermarkets represents approximately 3% of Sweden's annual energy use. Of this, the refrigeration system accounts for 50%. To reduce greenhouse gases introduced by energy generation, a larger share of renewable energy sources must be implemented. READ MORE

  6. 14. Concentration Difficulties in the School Environment - with focus on children with ADHD, Autism and Down's syndrome

    Author : Catrin Tufvesson; Institutionen för arkitektur och byggd miljö; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Down s syndrome; concentration; children; building process; ADHD; the Human Environment Interaction-model; individual adjusment; learning; indoor environment; school environment; Psykologi; Psychology; Humanities; Humaniora; autism;

    Abstract : The overall aim of this thesis was to identify environmental factors that affect children with ADHD, autism, and Down's syndrome and their ability to concentrate in their learning environment at school. The issue of this research is not to dismiss any of the additional resources these children are in need of; instead it is to suggest how to arrange learning environments in the most supportive way possible based on the initial needs of these children.
