1. 16. Energy efficiency of new residential buildings in sweden : Design and Modelling Aspects

   Författare :Itai Danielski; Inga Carlman; Thomas Olofsson; Mittuniversitetet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Energy security and climate change mitigation have been discussed in Sweden since the oil crisis in the 1970s. Sweden has since then increased its share of renewable energy resources to reach the highest level among the EU member states, but is still among the countries with the highest primary energy use per capita.

3. 17. Modelling Alternative Load Paths in Platform-Framed CLT Buildings : A Finite Element Approach

   Författare :Johannes Albert Josef Huber; Mats Ekevad; Ulf Arne Girhammar; Sven Berg; Sigurdur Ormarsson; Luleå tekniska universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; timber; robustness; finite element method; alternative load paths; disproportionate collapse; Träteknik; Wood Science and Engineering;

   Sammanfattning : Timber has become more popular as a construction material during recent years. Engineered wood products, such as glued laminated timber and cross-laminated timber, have enabled the construction of multi-storey buildings. Tall buildings with many occupants need to resist a disproportional collapse in case of unexpected exposures, e.g. LÄS MER

4. 18. Towards sustainability with building services systems : – by focusing on material choices, energy use and thermal indoor climates in residential buildings

   Författare :Mats Dahlblom; Avdelningen för Installations- och klimatiseringslära; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; residential apartment buildings; building services systems; energy use; hvac; hydronic heating system; heating control; feedback control loop; indoor temperature measurements; individual metering and billing; indoor temperature variations; thermal comfort; vertical temperature gradient; case study;

   Sammanfattning : For a development to be considered sustainable, social, economic and environmental requirements must be met. The Swedish sustainable development goals, based on Agenda 2030, contain 16 national environmental quality goals. The National Board of Housing, Building and Planning is responsible for achieving the goal "A good built environment". LÄS MER

5. 19. Vibrations in lightweight structures - Efficiency and reduction of numerical models

   Författare :Ola Flodén; Byggnadsmekanik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Multi-storey wood buildings have been increasing in popularity since a century-old ban on the construction of such buildings was lifted in 1994. Compared to conventional concrete structures, it is more difficult to build lightweight structures in such a way that noise and disturbing vibrations is avoided. LÄS MER

7. 20. Numerical Modelling of Timber Building Components to Prevent Disproportionate Collapse

   Författare :Johannes A. J. Huber; Sven Berg; Dick Sandberg; Mats Ekevad; Ulf Arne Girhammar; Jan-Willem G. van de Kuilen; Luleå tekniska universitet; []
   Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element modelling; alternative load paths; cross laminated timber; progressive collapse; CT scanning; fibre reconstruction; image analysis; Träteknik; Wood Science and Engineering;

   Sammanfattning : An increasing number of multi-storey buildings are being constructed with engineered wood products, such as glulam or cross-laminated timber (CLT). Multi-storey timber buildings can be safely designed for foreseeable loads, but knowledge is limited concerning their ability to survive unforeseeable events, e.g. LÄS MER
