1. 11. Passive houses in Sweden - Experiences from design and construction

   Författare :Ulla Janson; Avdelningen för Energi och byggnadsdesign; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Leadership; Planning process; Building construction; Residential buildings; Passive house; Energy efficiency;

   Sammanfattning : The sector of residential buildings and service organizations uses 36% of the total energy in Sweden. In June 2006, it was decided by the Swedish parliament that the energy use in residential buildings and premises should decrease by 20% per heated unit area before 2020. LÄS MER

3. 12. Microbial degradation of wooden foundation piles in urban context – causes and concerns

   Författare :Johanna Elam; Göteborgs universitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Modern infrastructural projects can endanger historical piled foundations supporting cultural heritage buildings, as groundwork can affect the subsurface environment by lowering the local groundwater level and increasing oxygenation in the soil. Wooden foundation piles are thereby placed at risk, as the durability of buried wood material is dependent on a stable, waterlogged, and anoxic environment. LÄS MER

4. 13. A Virtual Design Studio for Low-Frequency Sound from Walking in Lightweight Buildings

   Författare :Nata Amiryarahmadi; Sweden Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lightweight floors; Walking sound; Low frequency; Annoyance; Virtual design studio;

   Sammanfattning : In recent years there has been a growing interest for building lightweight multistorey woodenresidential buildings in countries like Sweden with large and renewable forests. While positive aspectsof these buildings, such as sustainability, ease of construction and lightness, motivate building more inwood, poor acoustic performance is a risk which concerns the wooden-building industry.

5. 14. 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

7. 15. Byggnadsteknik och timmermanskonst: en studie med exempel från några medeltida knuttimrade kyrkor och allmogehus

   Författare :Peter Sjömar; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wood building techniques; timber construction; corner-joints; medieval building techniques;

   Sammanfattning : This survey deals with building techniques based on the use of horizontally laid logs with interlocking corner-joints. The aim is to make an inventory of buildings methods and materials, based on existing medieval buildings, literary sources and current methods of carpentry.Chapter 1. A commentary on research and documentation. LÄS MER
