1. 1. Primary energy use of residential buildings : implications of materials, modelling and design approaches

   Författare :Uniben Yao Ayikoe Tettey; Leif Gustavsson; Ambrose Dodoo; Jan-Olof Dalenbäck; Linnéuniversitetet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; primary energy use; material production; simulation; input parameters; design strategies; climate change; overheating; residential buildings; Technology byts ev till Engineering ; Teknik; Byggteknik; Civil engineering;

   Sammanfattning : Buildings can play an essential role in the transition to a sustainable society. Different strategies, including improved energy efficiency in buildings, substitution of carbon intensive materials and fuels, efficient energy supply among others can be employed for this purpose.

3. 2. Analysis of Industrial Microwave Ovens

   Författare :Magnus Sundberg; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; source model; heat transfer; moment method; finite difference time domain; TM applicator; GMT; edge diffraction; thermal simulation; MMP; FDTD; generalized multipole technique; cost function; MM; optimization; magnetron; simulated annealing; multiple multipole program; microwave heating; edge overheating; TE applicator; tunnel-oven; applicator;

   Sammanfattning : This thesis deals with the analysis and design of microwave ovens used in the food industry. Such analysis is desirable in order to optimize the performance of the ovens and to reduce the time and expenses of developing new or improved ovens. LÄS MER

4. 3. Load Adapted Solar Thermal Combisystems - Optical Analysis and Systems Optimization

   Författare :Svante Nordlander; Högskolan Dalarna; []
   Nyckelord :Solar Combisystems Concentrating Collector Optimization Incidence Angle Optical Efficiency Simulation TRNSYS Stagnation;

   Sammanfattning : In a northern European climate a typical solar combisystem for a single family house normally saves between 10 and 30 % of the auxiliary energy needed for space heating and domestic water heating. It is considered uneconomical to dimension systems for higher energy savings. Overheating problems may also occur. LÄS MER

5. 4. Cooling demand in commercial buildings-The influence of building design

   Författare :Hendrik Voll; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar factor; influence of design; cooling load; Commercial buildings; energy need; window share;

   Sammanfattning : Large window areas and glass façades have become popular by architects. As the glass architecture has become fashionable in quite a short time it seems that the architects are not always aware of the energy consuming consequences that the highly glazed buildings, sometimes in combination with special room plans might cause.
