  1. 1. Orsaker till fel i byggandet: en studie om felorsaker, felkonsekvenser, samt hinder för inlärning i byggprojekt

    University dissertation from Chalmers University of Technology

    Author : Per-Erik Josephson; Chalmers tekniska högskola.; Chalmers University of Technology.; [1994]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell teknik och ekonomi; Industrial engineering and economy; building project; temporary organisations; defects; causes of defects; consequences of defects; costs of defects; organisational behaviour; organisational learning; quality;

    Abstract : One means of increasing the effectiveness of building is minimisation of the numbers of de-fects and their consequences. In order to accomplish this, it is necessary to have knowledge of why defects occur, of their consequences, and of how to learn from errors. READ MORE

  2. 2. Heat transfer through a well insulated external wooden frame wall : an investigation of the effects of normal defects in the insulation resulting from incident wind and air flow through the wall

    University dissertation from Byggnadsfysik LTH, Lunds Tekniska Högskola

    Author : Peter Roots; Lunds universitet.; Lund University.; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Electrical conduits.; Nogging pieces; Airgaps; Breaks in the insulation; Variations in the insulation; Through wind; Forced convection; Incident wind; Byggnadsteknik;

    Abstract : The heat requirement of a building can turn out to be greater than was calculated at the design stage. The reason for this may be that heat transport though the building envelope is greater than expected. This in turn can be due to the structure not fulfilling the design requirements in respect of windtightness and airtightness. READ MORE

  3. 3. Mould on building materials - A calorimetric study of fungal activity as a function of environmental factors

    University dissertation from Division of Building Materials, LTH, Lund University

    Author : Yujing Li; Lunds universitet.; Lund University.; [2007]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materiallära; byggnadsteknik; building construction; fungal activity; temperature; relative humidity; building; image analysis; indoor environment; wood; materialteknik; material technology; mould; calorimetry; isothermal calorimeter;

    Abstract : Mould problems in buildings have become a growing concern during the past decades. The growth of mould fungi indoors deteriorates air quality, influences human health and causes economical losses. Preventing mould growth from occurring is a more cost effective option than cleaning and renovation of buildings with mould problems. READ MORE

  4. 4. Benefits of strengthening timber with fibre-reinforced polymers

    University dissertation from Chalmers University of Technology

    Author : Alann André; Chalmers tekniska högskola.; Chalmers University of Technology.; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Byggnadsteknik; Building engineering; Konstruktionsmaterial; Construction materials; Timber; Experimental results; Compression failure parallel to the grain; Ductility; Kinkband; Analytical model; Numerical model; Tension perpendicular to the grain; FRP; Composite materials; Flax; Carbon; Reinforcement;

    Abstract : As a material, timber offers a wide range of alternatives in terms of structural applications. The natural defects present in timber are, however, the source of large variations in mechanical properties. READ MORE

  5. 5. Vacuum insulation in buildings Means to prolong service life

    University dissertation from Stockholm : KTH

    Author : Thomas I. Thorsell; KTH.; [2006]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum insulation; thermal bridge; serpentine edge; coated film; TECHNOLOGY Civil engineering and architecture Building engineering; TEKNIKVETENSKAP Samhällsbyggnadsteknik och arkitektur Byggnadsteknik;

    Abstract : Vacuum insulation panels, VIPs, constitute a new insulation material, 6 to 8 times better than traditional insulation materials, which utilizes the positive influence vacuum has on the thermal properties of certain materials. A VIP is a composite with a flat core enclosed by an envelope preventing the core to fill with gas. READ MORE
