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

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

   Sammanfattning : 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. LÄS MER

3. 7. Building-related renewable electricity production with storage and energy-efficient buildings : Exploring barriers, drivers and quality assurance

   Författare :Anna-Lena Lane; Mathias Cehlin; Thomas Olofsson; Högskolan i Gävle; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency gap; energy performance gap; ByggaE; battery storage; barriers; drivers; Non-energy benefits NEB; questionnaire; quality assurance; PV; energieffektivisering; energieffektiva byggnader; kvalitetssäkring; byggprocessen; ByggaE; solel; batterilager; hinder; drivkrafter; enkätstudie; Hållbar stadsutveckling; Sustainable Urban Development;

   Sammanfattning : There is a need to reduce unsustainable use of fossil fuels. Increased usage of renewable energy by combined use of photovoltaic solar panels (PV) with battery storage is one way. Another way is to increase awareness of energy usage and reduce the energy performance gap by building energy-efficient buildings. LÄS MER

4. 8. Borehole Thermal Energy Storage Systems for Storage of Industrial Excess Heat : Performance Evaluation and Modelling

   Författare :Emil Nilsson; Patrik Rohdin; Maria Andersson; Mathias Cehlin; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : Improving industrial energy efficiency is considered an important factor in reducing carbon dioxide emissions and counteract climate change. For many industrial companies in cold climates, heat generated at the site in summer will not be needed to fulfil the site heat demand during this time, and is thus removed to the outdoor air.

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

   Författare :Jessika Steen Englund; Bahram Moshfegh; Mathias Cehlin; Jan Akander; Tomas Persson; Högskolan i Gävle; []
   Nyckelord :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;

   Sammanfattning : 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. LÄS MER
