2. 1. Orsaker till fel i byggandet: en studie om felorsaker, felkonsekvenser, samt hinder för inlärning i byggprojekt

   Author : Per-Erik Josephson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; consequences of defects; causes of defects; organisational behaviour; organisational learning; building project; quality; temporary organisations; defects; costs of defects;

   Abstract : One means of increasing the effectiveness of building is minimisation of the numbers of de-fects and their consequences. In order to accomplish this, it is necessary to have knowledge of why defects occur, of their consequences, and of how to learn from errors. READ MORE

4. 2. Heat transfer through a well insulated external wooden frame wall : an investigation of the effects of normal defects in the insulation resulting from incident wind and air flow through the wall

   Author : Peter Roots; Avdelningen för Byggnadsfysik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Electrical conduits.; Nogging pieces; Airgaps; Breaks in the insulation; Variations in the insulation; Through wind; Forced convection; Incident wind; Byggnadsteknik;

   Abstract : The heat requirement of a building can turn out to be greater than was calculated at the design stage. The reason for this may be that heat transport though the building envelope is greater than expected. This in turn can be due to the structure not fulfilling the design requirements in respect of windtightness and airtightness. READ MORE

5. 3. Vacuum insulation in buildings : Means to prolong service life

   Author : Thomas I. Thorsell; Gudni Jóhannesson; Christer Sjöström; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; vacuum insulation; thermal bridge; serpentine edge; coated film; Building engineering; Byggnadsteknik;

   Abstract : Vacuum insulation panels, VIPs, constitute a new insulation material, 6 to 8 times better than traditional insulation materials, which utilizes the positive influence vacuum has on the thermal properties of certain materials. A VIP is a composite with a flat core enclosed by an envelope preventing the core to fill with gas. READ MORE

6. 4. Mould on building materials - A calorimetric study of fungal activity as a function of environmental factors

   Author : Yujing Li; Avdelningen för Byggnadsmaterial; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; materiallära; byggnadsteknik; building construction; fungal activity; temperature; relative humidity; building; image analysis; indoor environment; wood; materialteknik; material technology; mould; calorimetry; isothermal calorimeter;

   Abstract : Mould problems in buildings have become a growing concern during the past decades. The growth of mould fungi indoors deteriorates air quality, influences human health and causes economical losses. Preventing mould growth from occurring is a more cost effective option than cleaning and renovation of buildings with mould problems. READ MORE

7. 5. An Algorithmic Framework for Intelligent Concrete Structural Defects Detection and Classification

   Author : Ali Mirzazade; Björn Täljsten; Cosmin Popescu; Thomas Blanksvärd; Diogo Rodrigo Ferreira Ribeiro; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Civil Engineering Structures; defect detection; Structural Health Assessment; Bridge Inspection; Computer Vision; Point-Cloud Generation; Severity Assessment; Machine Learning Regression; Bridge 3D Modeling; Unmanned Inspections; Byggkonstruktion; Structural Engineering;

   Abstract : The primary objective of inspecting concrete civil structures is to gather information concerning the deterioration of concrete elements, including issues like concrete cover cracking, delamination, or corrosion. Typically, this data is documented through field inspection notes, hand-drawn sketches, and photographs. READ MORE
