  1. 1. Investigating Consumer Perceptions by applying the Extended Association Pattern Technique : A Study on Wooden Multistory Houses

    Author : Tobias Schauerte; Anders Baudin; Anders Pehrsson; Udo Mantau; Växjö universitet; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Means-End Chain Theory; Means-End Theory; laddering technique; laddering; Association Pattern Technique; end use analysis; wooden multistory houses; timber construction; wood construction; wooden housing; Business and economics; Ekonomi; Forestry and Wood Technology; Skog och träteknik;

    Abstract : During the past years, the usage of wood as construction material in multistory applications has increased. In Germany and Sweden, various activities have been, and are about to be performed, to accentuate and improve the position of wooden multistory houses. READ MORE

  2. 2. Perceptions of Wooden Multifamily Houses : Applying an Extended Association Pattern Technique

    Author : Tobias Schauerte; Anders Baudin; Anders Pehrsson; Arno Frühwald; Växjö universitet; []

    Abstract : This doctoral thesis concerns flanking transmission in light weight, wooden multi-storey buildings within the low frequency, primarily 20-120 Hz. The overall aim is to investigate how the finite element method can contribute in the design phase to evaluate different junctions regarding flanking transmission. READ MORE

  4. 4. Vibroacoustic performance of wooden buildings : Prediction and Perception

    Author : Juan Negreira; Teknisk akustik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Prediction tools; Low frequency vibrations; Vibroacoustics; Wooden buildings; Impact sound insulation; Finite element method; Vibration measurements; Flanking transmission; Elastomers; Design indicators; Vibration acceptability; Vibration annoyance; MEMS accelerometers;

    Abstract : 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. READ MORE

  5. 5. Wastewater generated by the wooden floor industry : Treatability investigation applying individual and coupled technologies
