   Sammanfattning : When the Swedish building regulations in 1994 allowed wooden multi-storey buildings to be built, this type of lightweight construction became popular due to its low cost and ease of construction, as well as wood being a plentiful resource in Sweden. However, complaints amid inhabitants are often reported due to nuisances caused by disturbing vibrations and noise propagating in the building. LÄS MER

4. 3. Characterization, toxicity and treatment of wood leachate generated outdoors by the wood-based industry

   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Wood leachate; Log yard runoff; Stormwater; Toxicity; Artemia salina; Vibrio fischeri; Constructed wetlands; Forestry and Wood Technology; Skog och träteknik;

   Sammanfattning : Wood is a natural raw material, and would hardly be considered a risk to the environment. However, the handling of wood materials on an industrial scale has been shown to have a negative impact on water bodies that run-off from industrial sites that process wood-based materials. LÄS MER

5. 4. A Virtual Design Studio for Low-Frequency Sound from Walking in Lightweight Buildings

   Författare :Nata Amiryarahmadi; Sweden Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lightweight floors; Walking sound; Low frequency; Annoyance; Virtual design studio;

   Sammanfattning : In recent years there has been a growing interest for building lightweight multistorey woodenresidential buildings in countries like Sweden with large and renewable forests. While positive aspectsof these buildings, such as sustainability, ease of construction and lightness, motivate building more inwood, poor acoustic performance is a risk which concerns the wooden-building industry.

7. 5. Configuration of modularised building systems

   Författare :Patrik Jensen; Miklos Molnar; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Construction Engineering and Management; Byggproduktion;

   Sammanfattning : Swedish building industry is mainly project-oriented where the design process is sequential involving various disciplines separated both in time and space. During the last decades the industry has been criticised and accused of having problems with quality and low productivity. LÄS MER
