1. 21. 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

3. 22. Optimization of ground-coupled systems for heating and cooling of buildings

   Författare :Jüri Naumov; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; free-cooling; brine temperature; heat pump; ground system; heating demand; storage; building load; cooling demand; Borehole;

   Sammanfattning : The use of ground-coupled systems in commercial buildings offers economic as well as environmental advantages. When both heating and cooling is required, a ground-coupled system can function both as a heat source and a heat sink. At the same time, it can also serve as a short term as well as a seasonal storage. LÄS MER

4. 23. Regulating energy performance of residential buildings in cold climate : a study of indicators, criteria, and evaluation methods

   Författare :Ingrid Allard Stolterman; Thomas Olofsson; Gireesh Nair; Folke Björk; Umeå universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy performance; building simulation; cold climate; energy use; indicators; evaluation methods; building regulations; residential buildings; energy measurements; performance gap; energy signature; sustainable development; hållbar utveckling; fysik; Physics;

   Sammanfattning : Building energy performance has been important in Fennoscandia ever since the early vernacular houses, to combat the cold climate. Due to EU directive 2010/31/EU on the energy performance of buildings (EPBD recast), building energy performance has become even more relevant in northern Europe the last decade. LÄS MER

5. 24. The Structure of Chinese Timber Architecture Twelfth century design standards and construction principles

   Författare :Qinghua Guo; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; units of measurement; design standards; timber structure; Chinese architecture; building patterns; carpentry system; construction principles; proportion; modular design;

   Sammanfattning : This thesis examines the building standards and construction principles prescribed and used in the construction of state buildings of the Song Dynasty (960 - 1279), China, from the viewpoint of architectural design. It aims to answer three fundamental questions: (1) What measuring system was used in the carpentry design and construction? (2) What building scales and proportions were prescribed for and used in state buildings of the time? (3) What were the interrelations of the structural patterns and roof types, and what were their relationships to the building scales and proportions? The thesis begins by providing detailed explanations of the highly refined and unique Song period modular system which governed not only the sizes of each individual elements, but also the dimensions of structural grids and the proportion of entire building.

7. 25. Single and Double Skin Glazed Office Buildings - Analyses of Energy Use and Indoor Climate

   Författare :Harris Poirazis; Avdelningen för Energi och byggnadsdesign; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermal environment; indoor climate; energy use; building performance; building simulations; double skin façades; Glazed office buildings; single skin façades; thermal comfort;

   Sammanfattning : The energy efficiency and thermal performance of highly glazed office buildings are often questioned. However, nowadays glazed buildings are increasingly being built around the world, mainly due to an architectural trend, followed by the preference of companies to a distinctive image that a glazed office building can provide.
