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

    Författare :Lars Olsson; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Moisture Conditions in Exterior Wooden Walls and Timber During Production and Use

    Författare :Lars Olsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory test; MRD-index; moisture; driving rain; hysteresis; wood; precipitation; timber; weather barrier; mould growth; façade; wall; wind barrier; measurement; field test; mold;

    Sammanfattning : Thermal insulation of building envelopes has improved over the years. This means that building envelope have become more susceptible to defects, with an increased risk of moisture damage. The criteria for energy consumption have become more rigorous, but the shift should not lead to moisture problems. LÄS MER

  4. 3. Technology Carriers: The Role of Engineers in the Expanding Swedish Shipbuilding System

    Författare :Lars O. Olsson; Chalmers tekniska högskola; []
    Nyckelord :HUMANIORA; HUMANITIES; sociotechnical systems; shipbuilding; engineering education; 20-th century; user-producer interaction; professional associations; engineers; technological systems; technological knowledge; history of technology; systems of innovation; industrial research;

    Sammanfattning : This study analyses the process which shaped the role or function of college-trained engineers within a technological system or innovation system during the period from the start of the 20th century until the 1950s and 1960s. With a conceptual framework of sociotechnical systems and of engineers as a social group of technology carriers this process is studied in one particular system, namely the Swedish shipbuilding system.
