2. 1. Evaluating energy efficient buildings : Energy- and moisture performance considering future climate change

   Author : Björn Berggren; Institutionen för arkitektur och byggd miljö; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Net Zero Energy Building; passive house; thermal bridge; building envelope; energy performance; moisture performance; multi criteria decision making; climate change; climate scenarios; EN ISO 13789; EN ISO 10211;

   Abstract : One of the greatest challenges the world is facing is climate change. The need of reduction of energy use and an increased use of renewable energy in buildings constitutes important climate change mitigation measures. READ MORE

4. 2. Evaluating building envelopes for energy efficient buildings : Energy- and moisture performance considering future climate change

   Author : Björn Berggren; Avdelningen för Energi och byggnadsdesign; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Buildings account for a signifi cant proportion of the energy use thatgenerates greenhouse gases and consequently drives the ongoing climatechange. As the population of the world increases, the need for buildingsincreases, while the energy use needs to decrease. READ MORE

5. 3. Advances in Thermal Insulation : Vacuum Insulation Panels and Thermal Efficiency to Reduce Energy Usage in Buildings

   Author : Thomas Thorsell; Folke Björk; Mark Bomberg; Targo Kalamees; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vacuum insulation panels; VIP; serpentine edge; thermal bridge; composite film; gas diffusion; defect dominated; holistic approach; building enclosure; integrated testing and modeling; energy equivalent; field performance; air flow; thermal insulation efficiency;

   Abstract : We are coming to realize that there is an urgent need to reduce energy usage in buildings and it has to be done in a sustainable way. This thesis focuses on the performance of the building envelope; more precisely thermal performance of walls and super insulation material in the form of vacuum insulation. READ MORE

6. 4. Testing large samples of PCM in water calorimeter and PCM used in room applications by night-air cooling

   Author : Rickard Bellander; Ove Söderström; Gudni Jóhannesson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-change material; PCM; water calorimeter; air heat exchanger; durability; thermal properties; heat capacity; Building engineering; Byggnadsteknik;

   Abstract : The latent-heat-storage capacity in Phase-Change Materials can be used for storing or releasing energy within a small temperature interval. Upon the phase transition taking place in a narrow temperature span, the material takes up or releases more energy compared to sensible heat storage. READ MORE

7. 5. Aerogel-based plasters for renovation of buildings in Sweden: Identification of possibilities, information deficiencies and challenges

   Author : Ali Naman Karim; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; compatibility; durability; plaster; mechanical; render; energy efficient retrofitting; hygrothermal; renovation; listed building; Aerogel;

   Abstract : Aerogel-based plasters are a class of high energy efficient wall finishes with declared thermal conductivities around 30-50 mW/(m∙K). Aerogel-based plasters are promising alternatives to substitute conventional insulation materials when renovating uninsulated building envelopes. READ MORE
