  2. 21. Concrete slab on the ground and moisture control : verification of some methods to improve the moisture conditions in the foundation

    Author : Lars-Erik Harderup; Avdelningen för Byggnadsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Concrete slab; moisture; repair methods; ventilated foundation; drainage; numerical methods; grunder; grundplattor; platta på mark; betongplattor; fuktskador; reparationsmetoder; dränering; ventilerade konstruktioner; fukt; fukttransport; relativ fuktighet; temperatur; luftflöden; beräkningsmodeller; teori; fältundersökningar; mätresultat;

    Abstract : This work deals with different types of repair methods for concrete slab on the ground damaged by moisture. Many of the available methods involve some kind of mechanical ventilation of the foundation. The basic principle for all these systems is the same. READ MORE

  5. 23. Critical Moisture Conditions for Mould Growth on Building Materials

    Author : Pernilla Johansson; Avdelningen för Byggnadsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mould; critical moisture level; building material; relative humidity; mould resistance; crawl space; attic;

    Abstract : Materials that are stored or used in damp climates may be subject to mould growth. However, all materials are not equally susceptible to mould growth. For each specific material, there is a critical moisture level. If this is exceeded, there is a risk that mould fungi will develop on the material. READ MORE

  6. 24. Solar Colletors Combined with Ground-Source Heat Pumps in Dwellings - Analyses of System Performance

    Author : Elisabeth Kjellsson; Avdelningen för Byggnadsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heating in dwellings; TRNSYS simulations; solar collectors; ground-source heat pumps; ground heat;

    Abstract : The use of ground-source heat pumps for heating buildings and domestic hot water in dwellings is increasing rapidly in Sweden. The heat pump extracts heat from the ground by a U-pipe in a vertical borehole. In order to reduce the electricity demand in the system, the combination with solar collectors is introduced.

  7. 25. Moisture safety in wood frame walls : blind evaluation of the hygrothermal calculation tool WUFI 5.0 using field measurements and determination of factors affecting the moisture safety

    Author : Solof Mundt Petersen; Avdelningen för Byggnadsfysik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Due to increased awareness of climate change and higher energy costs, well‐insulated buildings have become more common. Furthermore, the interests of using wood in building to produce more carbon dioxide‐efficient houses have increased. READ MORE
