  1. 26. Modeling and Simulation of Electricity Consumption Profiles in the Northern European Building Stock

    Författare :Claes Sandels; Lars Nordström; Palensky Peter; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Demand Response; Flexible loads; Building stock energy-use; Bottom-up simulation models; Load profiles; Non-homogeneous Markov-chains; End-user behavior; Lumped capacitance models; HVAC system control; Smart Grid.; Efterfrågeflexibilitet; Flexibla laster; Energianvändning i byggnadsstocken; Botten-upp-simuleringsmodeller; Elförbrukningsprofiler; Icke-homogena Markovkedjor; Slutanvändarbeteenden; Värmedynamikmodellering; Styrning av HVAC-laster; Smarta elnät.;

    Sammanfattning : The electric power systems are currently being transformed through the integration of intermittent renewable energy resources and new types of electric loads. These developments run the risk of increasing mismatches between electricity supply and demand, and may cause non-favorable utilization rates of some power system components. LÄS MER

  3. 27. Designing for shared energy responsibility

    Författare :Hanna Hasselqvist; Cristian M Bogdan; Elina Eriksson; Ylva Fernaeus; Mike Hazas; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; human-computer interaction; design; sustainability; practices; energy; mobility; Human-computer Interaction; Människa-datorinteraktion;

    Sammanfattning : A significant part of the world’s carbon emissions is related to energy use for housing and personal transport, and there are many efforts to make this energy use more sustainable. In the field of Sustainable Human-Computer Interaction, there has been a great interest in exploring how interactive systems can be used to influence people’s energy use, often with a focus on providing information and encouraging energy users to change their behaviours.

  4. 28. Life cycle assessment of transport systems and transport infrastructure : Investigating methodological approaches and quantifying impacts at project and network levels

    Författare :Carolina Liljenström; Anna Björklund; Susanna Toller; Rolf André Bohne; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Strategier för hållbar utveckling; Strategies for sustainable development;

    Sammanfattning : Reducing greenhouse gas emissions from the transport sector is a key challenge to reach global climate targets and limit global warming to below 2 ºC. The use of life cycle assessment (LCA) may provide knowledge about the environmental impacts of transport systems so that emission reduction measures can be identified. LÄS MER

  5. 29. On the Effect of Occupant Behavior and Internal Heat Gains on the Building’s Energy Demand : A case study of an office building and a retirement home

    Författare :Jakob Carlander; Bahram Moshfegh; Jan Akander; Shahnaz Amiri; Sture Holmberg; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building energy simulation; energy efficiency indicators; occupant behaviour; energy performance; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : About 12% of the greenhouse gas emissions and 40% of the total energy use in the EU derive from the buildings. User behavior, construction, and HVAC systems has a significant impact on a building’s energy use. If a building is to be energy-efficient it is important to understand how all these parameters are connected. LÄS MER

  7. 30. Experimental study of an intermittent ventilation system in high occupancy spaces

    Författare :Alan Kabanshi; Patrik Sörqvist; Hans Wigö; Robert Ljung; Hazim Awbi; Högskolan i Gävle; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Intermittent airflow; Indoor air quality; Perceived air quality; Thermal sensation; thermal comfort; Air movement acceptability; Convective cooling; Cooling effect.; Intermittent luftflöde; Luftstrålar; Upplevd luftkvalitet; Termisk komfort; Acceptans av luftrörelser; Konvektiv kylning; Kyleffekt.; Hållbar stadsutveckling; Sustainable Urban Development;

    Sammanfattning : Spaces with high occupancy density like classrooms are challenging to ventilate and use a lot of energy to maintain comfort. Usually, a compromise is made between low energy use and good Indoor Environmental Quality (IEQ), of which poor IEQ has consequences for occupants’ health, productivity and comfort. LÄS MER
