   Abstract : Natural ventilation is the dominating ventilation process in ancient buildings like churches, and also in most domestic buildings in Sweden and in the rest of the world. These buildings are naturally ventilated via air infiltration and airing. READ MORE

4. 7. Multi-dimensional approach used for energy and indoor climate evaluation applied to a low-energy building

   Author : Fredrik Karlsson; Bahram Moshfegh; Hazim Awbi; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-energy building; energy; indoor climate; simulation; Lågenergihus; energi; inomhusklimat; simulering; Building engineering; Byggnadsteknik;

   Abstract : The building sector alone accounts for almost 40% of the total energy demand and people spend more than 80% of their time indoors. Reducing energy demand in buildings is essential to the achievement of a sustainable built environment. At the same time, it is important to not deteriorate people’s health, well-being and comfort in buildings. READ MORE

5. 8. On the Effect of Occupant Behavior and Internal Heat Gains on the Building’s Energy Demand : A case study of an office building and a retirement home

   Author : Jakob Carlander; Bahram Moshfegh; Jan Akander; Shahnaz Amiri; Sture Holmberg; Högskolan i Gävle; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building energy simulation; energy efficiency indicators; occupant behaviour; energy performance; Hållbar stadsutveckling; Sustainable Urban Development;

   Abstract : About 12% of the greenhouse gas emissions and 40% of the total energy use in the EU derive from the buildings. User behavior, construction, and HVAC systems has a significant impact on a building’s energy use. If a building is to be energy-efficient it is important to understand how all these parameters are connected. READ MORE

6. 9. Water resistance of Scots pine joints produced by linear friction welding

   Author : Mojgan Vaziri; Lars-Olof Nilsson; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood; wood welding; crack; CT scanning; image processing; MRI; microdensitometry; CPMAS C NMR; density; water absorption; tensile-shear strength; Träteknik; Wood Technology;

   Abstract : Wood welding is a mechanical friction process allowing the assembly of timber without any adhesives. The process consists of applying mechanical friction, under pressure, alternately to the two wood surfaces to be welded. READ MORE

7. 10. On the performance of stratified ventilation

   Author : Ulf Larsson; Bahram Moshfegh; Per Heiselberg; Högskolan i Gävle; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hållbar stadsutveckling; Sustainable Urban Development;

   Abstract : People nowadays spend most of their time indoors, for example in their homes, cars, in trains, at work, etc. In Sweden, the energy demand in the built environment is a growing issue. READ MORE
