1. 1. Risk Assessment of Hygrothermal Performance - Building Envelope Retrofit

   Författare :Simon Pallin; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; retrofit; Risk; hygrothermal; simulations.; residential; mold; energy savings;

   Sammanfattning : A risk assessment of the hygrothermal performance for a building envelope retrofit investigates possible variations in energy performance, indoor environment quality and moisture safety and elaborates on the risks of exceeding defined acceptance criteria. These risks can be properly determined if including the variability of, by the investigated retrofit, most influencing parameters. LÄS MER

3. 2. Retrofitting of old Exterior Wall with Vacuum Insulation Panels: Measurements of Thermal Properties, Moisture Performance and Practical Considerations

   Författare :Pär Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hygrothermal sensor; listed building; transient plane source; retrofitting; indoor moisture supply; vacuum insulation panel; hygrothermal simulation; exterior wall;

   Sammanfattning : The building industry is facing one of its most challenging tasks ever. Until 2050 the energy use for heating of buildings should be decreased by 50% which means a large part of the building stock have to be retrofitted to become more energy efficient. One of the possible solutions is to add thermal insulation to the exterior wall of the buildings. LÄS MER

4. 3. Hygrothermal Simulations of Buildings Concerning Uncertainties of the Future Climate

   Författare :Vahid Nik; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mould growth; climate change; climate uncertainties; hygrothermal simulation; energy demand;

   Sammanfattning : Global warming and its effects on climate are of great concern. Climate change can affect buildings in different ways, i.e. it can change the energy demand or the moisture durability of buildings in the future. LÄS MER

5. 4. The hygrothermal inertia of massive timber connstructions

   Författare :Stéphane Hameury; Ove Söderström; Carsten Rode; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 1H MRI; Building simulation environment; Heat buffering capacity; Heavy timber construction; Indoor climate; In-situ measurement; Magnetic Resonance Imaging; Building manufacturing engineering; Byggproduktionsteknik;

   Sammanfattning : The work presented in this Doctoral dissertation concerns the ability of heavy timber structures to passively reduce the fluctuations of the indoor temperature and of the indoor relative humidity, through the dynamic process of heat and moisture storage in wood. We make the hypothesis that the potential offered by the hygrothermal inertia of heavy timber structures is significant, and that it could provide a passive way of regulating the indoor climate.

7. 5. Building Retrofit using Vacuum Insulation Panels: Hygrothermal Performance and Durability

   Författare :Pär Johansson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laboratory; retrofitting; interior insulation; listed building; field study; exterior wall; brick wall; numerical simulation; wooden beam ends; measurement; vacuum insulation panel; transient plane heat source; exterior insulation;

   Sammanfattning : Many old buildings have unsatisfactory thermal performance compared to the standards of today. One way to increase the thermal performance is to add thermal insulation to the building envelope. However, many old buildings are listed and considered to be valuable for historical and esthetic reasons. LÄS MER
