2. 1. Prediction of Energy Use of a Swedish Secondary School Building : Building Energy Simulation, Validation, Occupancy Behaviour and Potential Energy-Efficiency Measures

   Author : Jessika Steen Englund; Bahram Moshfegh; Mathias Cehlin; Jan Akander; Tomas Persson; Högskolan i Gävle; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building energy simulation; school building; field measurements; energy use; heat power demand; validation; occupancy behaviour; airing; energy-efficiency measures; byggnadssimulering; skolbyggnad; fältmätningar; energianvändning; värmeeffektbehov; validering; brukarbeteende; vädring; energieffektiviseringsåtgärder; Hållbar stadsutveckling; Sustainable Urban Development;

   Abstract : Residential and public buildings account for about 40% of the annual energy use in Europe. Many buildings are in urgent need of renovation, and reductions in energy demand in the built environment are of high importance in both Europe and Sweden. Building energy simulation (BES) tools are often used to predict building performance. READ MORE

   Abstract : In Sweden, buildings are responsible for about 40 % of total energy use and about 10 % of total CO2 emissions Today more than 60 % of existing Swedish residential buildings are over 40 years old and are in need of major renovation. In addition, 15 % of all multi-family buildings and 27 % of all single-family houses were built before 1945. READ MORE

5. 3. Improved building energy simulations and verifications by regression

   Author : Jimmy Vesterberg; Thomas Olofsson; Folke Björk; Umeå universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Calibrated simulations; Energy signature; Regression; BES; IDA ICE; Multifamily buildings; EUI;

   Abstract : It is common with significant differences between calculated and actual energy use in the building sector. These calculations are often performed with whole building energy simulation (BES) programs. In this process the analyst must make several assumptions about the studied building and its users.

6. 4. Radiation properties of coil-coated steel in building envelope surfaces and the influence on building thermal performance

   Author : Ali Joudi; Bahram Moshfegh; Mats Rönnelid; Harald Svedung; Mathias Cehlin; Runming Yao; Högskolan Dalarna; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy and Built Environments; Energi och samhällsbyggnad;

   Abstract : Recent studies have shown that the optical properties of building exterior surfaces are important in terms of energy use and thermal comfort. While the majority of the studies are related to exterior surfaces, the radiation properties of interior surfaces are less thoroughly investigated. READ MORE

7. 5. Evaluation of Thermal Comfort and Night Ventilation in a Historic Office Building in Nordic Climate

   Author : Hossein Bakhtiari; Mathias Cehlin; Jan Akander; Abolfazl Hayati; Patrik Rohdin; Högskolan i Gävle; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; historic buildings; office buildings; Nordic climate; thermal comfort; field on-site measurements; standardized questionnaire; building management system BMS ; night ventilation NV ; building energy simulation BES ; IDA-ICE; Hållbar stadsutveckling; Sustainable Urban Development;

   Abstract : Envelopes with low thermal performance are common characteristics in European historic buildings resulting in insufficient thermal comfort and higher energy use compared to modern buildings. There are different types of applications for the European historic buildings such as historic churches, historic museums, historic theatres, etc. READ MORE
