  1. 1. 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

  2. 2. 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

  3. 3. Driving rain tightness, intrusion rates and phenomenology of leakages in defects of façades: A new calculation algorithm

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Lars Olsson; [2018]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; façade details; rain resistance; window-wall interface; EN 12865; protrusion; deficiency; catch area; water flow; obstacle; fenestration; dam; driving rain; water leakage; leakage flow; hole;

    Abstract : This thesis presents the driving rain tightness of façades with façade details as well as the water leakage flows that can be expected. Furthermore, it describes the key mechanisms for water leakage in defects in the outermost layer of external walls. READ MORE

  4. 4. 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

  5. 5. Chloride initiated reinforcement corrosion in marine concrete

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

    Author : Paul Sandberg; Lunds universitet.; Lund University.; [1998]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; w c ratio; cover thickness; chloride penetration; service life prediction; corrosion cells; chloride thresholds; field exposure tests; marine concrete; pozzolans; reinforcement corrosion; chloride binding; Building construction; Byggnadsteknik;

    Abstract : Popular Abstract in Swedish Korrosion av stålarmering i betong orsakade höga reparationskostnader för Ölandsbron, och är en grundläggande fråga vid val av material och utförande för Öresundsbron. Avhandlingen behandlar hur val av betongkvalité och tjocklek hos betongen som skyddar armeringen påverkar dels hur fort saltvatten tränger in i betong för att till slut nå armeringen, dels hur mycket salt armeringen tål innan den börjar rosta.
