  2. 6. An analysis of the relationship between the energy and buildings sectors in Sweden

    Author : Mehmet Börühan Bulut; Björn Karlsson; Peter Stigson; Fredrik Wallin; Eriksson Ola Norrman; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy sector; buildings sector; energy efficiency; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Climate change is one of the global challenges of our time. The energy sector is at the focus of the European efforts to combat climate change as it accounts for 80% of the total greenhouse gas emissions in the European Union. READ MORE

  4. 7. Building as active elements of energy systems

    Author : Mehmet Börühan Bulut; Björn Karlsson; Fredrik Wallin; Peter Stigson; Jenny Palm; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; smart grid; smart home; cooperation; energy; buildings; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Buildings account for approximately 40% of the energy demand and 33% of the total greenhouse gas emissions in the European Union. Accordingly, there are several efforts that target energy efficiency in buildings both at the European and Swedish levels. The role of buildings in climate change mitigation, however, is not limited to energy savings. READ MORE

  5. 8. Energy Optimal Operation of Electric Trains : Development of a Driver Advisory System

    Author : Nima Ghaviha; Erik Dahlquist; Markus Bohlin; Fredrik Wallin; Evert Andersson; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : The electric traction system used in trains is the most energy efficient traction system in the transportation sector. Moreover, it has the least NOx and CO2 emissions in comparison to other transportation systems (e.g. busses, passenger cars, airplanes, etc. READ MORE

  6. 9. Increasing Energy Efficiency in Electric Trains Operation : Driver Advisory Systems and Energy Storage

    Author : Nima Ghaviha; Erik Dahlquist; Markus Bohlin; Fredrik Wallin; Rob M.P. Goverde; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Driver Advisory System; Catenary-free Operation; Electric Train; Electric Multiple Unit; Battery; Energy Efficiency; Energy Storage; Speed Profile Optimization; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Electric traction is the most efficient traction system in the railway transportation. However, due to the expensive infrastructure and high power demand from the grid, the share of electric trains in the railway transportation is still lower than other trains. READ MORE

  7. 10. Heat demand profiles of buildings' energy conservation measures and their impact on renewable and resource efficient district heating systems

    Author : Lukas Lundström; Erik Dahlquist; Fredrik Wallin; Björn Karlsson; Jan Akander; Sven Werner; Mälardalens högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating; energy conservation; weather normalisation; typical meteorological year; building energy simulation; system analysis; Energy- and Environmental Engineering; energi- och miljöteknik;

    Abstract : Increased energy performance of the building stock of European Union is seen as an important measure towards mitigating climate change, increasing resource utilisation efficiency and energy supply security. Whether to improve the supply-side, the demand-side or both is an open issue. READ MORE
