1. 31. Energy Efficiency in Shopping Malls : Some Aspects Based on a Case Study

   Författare :Sofia Stensson; Jan-Olof Dalenbäck; Per Fahlén; Monica Axell; Jeffrey Spitler; Sweden Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Shopping mall; energy use; energy efficiency; HVAC system; load patterns; case study; regulatory requirements; building code; and energy declarations;

   Sammanfattning : The building sector accounts for approximately 40 percent of our energy use. To reach existing environmental targets energy use will have to be reduced in all building types. At the European level, the main legislative instrument for improving the energy efficiency of the building stock is the Energy Performance of Buildings Directive (EPBD). LÄS MER

3. 32. On the Importance of Accounting Information for Stock Market Efficiency

   Författare :Jiri Novak; Jan-Erik Gröjer; Mattias Hamberg; Mats Åkerblom; Colin Clubb; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business studies; accounting; capital makets; efficiency; momentum; liquidity; accounting conservatism; transitory earnings; IFRS; goodwill; Sweden; Företagsekonomi; Business studies; Företagsekonomi;

   Sammanfattning : This thesis contributes to the discussion on the importance of accounting information for stock market efficiency. As any analysis of market efficiency depends on the use of adequate risk proxies, the thesis first investigates the ability of commonly used risk factors to explain the cross-sectional variation of Swedish stock returns.

4. 33. Energy Efficiency in Machine Learning : Approaches to Sustainable Data Stream Mining

   Författare :Eva García Martín; Håkan Grahn; Veselka Boeva; Emiliano Casalicchio; Jesse Read; Blekinge Tekniska Högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; machine learning; energy efficiency; data stream mining; green machine learning; edge computing; Computer Science; Datavetenskap;

   Sammanfattning : Energy efficiency in machine learning explores how to build machine learning algorithms and models with low computational and power requirements. Although energy consumption is starting to gain interest in the field of machine learning, still the majority of solutions focus on obtaining the highest predictive accuracy, without a clear focus on sustainability.
