1. 16. Multi-dimensional approach used for energy and indoor climate evaluation applied to a low-energy building

   Författare :Fredrik Karlsson; Bahram Moshfegh; Hazim Awbi; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-energy building; energy; indoor climate; simulation; Lågenergihus; energi; inomhusklimat; simulering; Building engineering; Byggnadsteknik;

   Sammanfattning : The building sector alone accounts for almost 40% of the total energy demand and people spend more than 80% of their time indoors. Reducing energy demand in buildings is essential to the achievement of a sustainable built environment. At the same time, it is important to not deteriorate people’s health, well-being and comfort in buildings. LÄS MER

3. 17. Thermal energy use in greenhouses : the influence of climatic conditions and dehumidification

   Författare :Katarzyna Maslak; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : In the North European greenhouses, energy use for climatization accounts for a significant share of the operational costs. Air temperature and humidity are important factors whose control is crucial for assuring high productivity and limited use of energy. LÄS MER

4. 18. State-of-the-art Integrated Refrigeration Systems in Supermarkets : An Energy Efficiency Evaluation Based on Field Measurements Analysis and Computer Simulations

   Författare :Mazyar Karampour; Samer Sawalha; Björn Palm; Silvia Minetto; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Carbon dioxide CO2 ; Supermarket; Supermarket refrigeration; Trans-critical cycle; Field meas-urements; Computer simulation; System integration; State-of-the-art; Heat recovery; Air condi-tioning; Reference HFC system; Geothermal energy storage; Energiteknik; Energy Technology;

   Sammanfattning : Supermarkets have become a vital feature of modern society. However, they have significant impact on the environment due to the large amount of refrigerants needed in the refrigeration system, and due to the large energy use in the supermarket, they are the commercial buildings with highest energy intensity.

5. 19. Uncertainty modeling for load flow and hosting capacity analysis of urban electricity distribution systems

   Författare :Umar Hanif Ramadhani; Joakim Widén; Joakim Munkhammar; Bri-Mathias Hodge; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Uncertainty model; Photovoltaics; Electric vehicle; Residential buildings; Hosting capacity; Probabilistic load flow; Electricity distribution systems; Urban Energy Systems; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

   Sammanfattning : Urban demographics are changing, with more than half of the global population currently residing in urban areas. Traditionally, cities are often seen as passive energy consumers relying on external centralized systems. Motivated by the need to mitigate climate change, a shift is underway as cities actively shape energy systems. LÄS MER

7. 20. Energy efficiency in shopping malls. Energy use and indoor climate

   Författare :Sofia Stensson; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy use; loads; cooling; Shopping mall; simulation; heating; field measurements;

   Sammanfattning : The purpose of this licentiate thesis is to describe energy use, heating and cooling demands and the relative importance of internal heat loads in shopping malls. It will be a foundation for a future doctorial thesis in which alternative energy efficient HVAC systems for shopping malls will be analysed. LÄS MER
