1. 16. Corporate and city GHG inventories : Impact on global CO2 emissionswhen considering electricity and CHP-based district heating

   Författare :Lena Nordenstam; Björn Karlsson; Louise Ödlund; Danica Djuric Ilic; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Sammanfattning : One initiative to reduce greenhouse gas (GHG) emissions involves developing standards for GHG inventories. Companies and cities (regions) can use GHG inventories to compile and report their GHG emissions. LÄS MER

3. 17. 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; []
