  2. 1. Dynamics of Energy Systems - Methods of analysing technology change

    Author : Lena Neij; Internationella miljöinstitutet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; evaluation; market transformation; PV modules; wind power; experience curves; air-distribution; lighting; vintage models; sustainable energy; renewable energy; energy efficiency; Energy; energy system; Energiforskning; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Abstract : Technology change will have a central role in achieving a sustainable energy system. This calls for methods of analysing the dynamics of energy systems in view of technology change and policy instruments for effecting and accelerating technology change. In this thesis, such methods have been developed, applied, and assessed. READ MORE

  4. 2. Energy Management in Large scale Solar Buildings : The Closed Greenhouse Concept

    Author : Amir Vadiee; Viktoria Martin; Philip Griffiths; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thermal Energy Storage; Energy Saving; Thermoeconomic Assessment; Energy Management Scenario; Micro Climate Control; Solar Building; Closed Greenhouse; SRA - Energy; SRA - Energi;

    Abstract : Sustainability has been at the centre of global attention for decades. One of the most challenging areas toward sustainability is the agricultural sector. Here, the commercial greenhouse is one of the most effective cultivation methods with a yield per cultivated area up to 10 times higher than for open land farming. READ MORE

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

    Author : Mazyar Karampour; Samer Sawalha; Björn Palm; Silvia Minetto; KTH; []
    Keywords : 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;

    Abstract : 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.

  6. 4. Small-Scale Decentralized Energy Systems : optimization and performance analysis

    Author : Sara Ghaem Sigarchian; Viktoria Martin; Anders Malmquist; Erik Dahlquist; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Small-scale polygeneration energy systems; techno-economic optimization; renewable energy; operating strategy; particle swarm optimization; optimization algorithm; decentralized energy system;

    Abstract : Small-scale polygeneration energy systems, providing multiple energy services, such as heating, electricity, cooling, and clean water, using multiple energy sources (renewable and non-renewable) are considered an important component in the energy transition movement. Exploiting locally available energy sources and providing energy services close to the end users have potential environmental, economic, and societal benefits. READ MORE
