1. 11. Methodology for the modelling of thermally activated building components in low exergy design

   Författare :Dietrich Schmidt; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building engineering; Byggnadsteknik;

   Sammanfattning : There is still an obvious and indisputable need for an increase in the efficiency of energy utilisation in buildings. Heating, cooling and lighting appliances in buildings account for more than one third of the world’s primary energy demand and there are great potentials, which can be obtained through better applications of the energy use in buildings.

3. 12. The Integration of 3D Geodata and BIM Data in 3D City Models and 3D Cadastre

   Författare :Jing Sun; Kent Eriksson; Anders Östman; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 3D geodata; BIM; city models; 3D cadastre; geometric quality; CityGML; LADM; laser scanning; Geodesy and Geoinformatics; Geodesi och geoinformatik; Geodesi; Geodesy;

   Sammanfattning : The initial geographic information system (GIS) and building information modelling (BIM) are designed and developed independently in order to serve different purposes and use. Within the prolific increase and growing maturity of three-dimensional (3D) technology, both 3D geodata and BIM data can specify semantic data and model 3D buildings that are prominent for the 3D city models and 3D cadastre.

4. 13. Modelling and simulation of building components : thermal interaction between multilayer wall and hydronic radiator

   Författare :Christian Brembilla; Thomas Olofsson; Per Sahlin; Persson Leif; Annika Moström; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydronic radiator; multilayer wall; efficiencies of emission; systemanalys; Systems Analysis; engineering science with specialization in microsystems technology; teknisk fysik med inriktningen mikrosystemteknik;

   Sammanfattning : Background and Scope: The scope of this thesis is to investigate the thermal behaviour of building components as hydronic radiator and multilayer walls subjected to dynamic conditions. The modelling and simulation of these building components provide information on how these components thermally interact among each other. LÄS MER

5. 14. Building Physics Tools: Needs, Use and the Lack of Use in the Building Process. Modelling Non-Isothermal Moisture Flow and Frost Penetration

   Författare :Stephen Burke; Avdelningen för Byggnadsfysik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; isothermal; costs; building physics tools; moisture damages; learning loop; experience; causal loop diagrams; non-isothermal; moisture transport;

   Sammanfattning : Despite advances in material science, computers and building technology, building failures related to building physics continue to occur. These failures range from a building not meeting its energy use target to a building causing people to become ill from exposure to various chemicals or biological organisms. LÄS MER

7. 15. The Development of a European Fire Classification System for Building Products - Test Methods and Mathematical Modelling

   Författare :Björn Sundström; Avdelningen för Brandteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Building construction; Byggnadsteknik; Teknik; Technological sciences; Brandteknik; Fire Protection Engineering; Conflame; Cone Tools; FDS; CFD; Duhamel?s integral; Fire Growth Rate; FIGRA; Euroclass; SBI; Single Burning Item; Cone Calorimeter; Room Corner Test; fire modelling; Reaction to fire; flashover;

   Sammanfattning : The fire technical properties of products are determining factors for the initiation and growth of fires. Measurement of fire technical properties and the understanding of how they relate to real hazards are therefore important for fire safety. LÄS MER
