  2. 1. Urban Building Energy Modeling for Retrofit Scenarios : Development, Calibration, Validation and Implementation for Swedish Residential Buildings

    Author : Fatemeh Johari; Joakim Widén; Darren Robinson; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Urban building energy modeling; Urban building energy retrofit; Urban energy system; Urban energy planning; Energy performance certificate; Energy efficiency; low-energy cities; Engineering Science with specialization in Civil Engineering and Built Environment; Teknisk fysik med inriktning mot byggteknik och byggd miljö;

    Abstract : The necessity for an accelerated transition of urban energy systems and, in particular, the building sector toward energy efficiency and carbon neutrality poses new challenges to planning and retrofitting existing buildings. To cope with these challenges, so-called urban building energy models (UBEMs) have been introduced for quantifying the energy demand in the building sector, identifying the hot spots of energy use and suggesting scenarios for retrofitting the buildings.

  4. 2. Novel Approaches for Retrofitting Heat Exchanger Networks Subject to Varying Operating Conditions

    Author : Christian Langner; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multi-Period Optimization; Flexibility; Critical Points; Feasibility; Heat Integration; Process Industry; Energy Efficiency; Retrofit;

    Abstract : The process industry is responsible for a significant share of the final industrial energy use in Sweden. In particular, the pulp and paper industry accounts for more than 50 %. In this context, a number of studies have shown that there is a substantial potential for energy savings in the pulp and paper industry. READ MORE

  5. 3. Operability Considerations for Retrofit Design of Industrial Process Energy Systems

    Author : Sofie Marton; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Interviews; Steam System; Heat integration; Implementation; Operability; Non-energy benefits;

    Abstract : Energy efficiency is crucial to reduce fuel usage and related emissions in industry.  In energy-intensive process industry, the use of heat accounts for a large share of the total energy use and a reduction of the heating and cooling demand is thus important for decreasing energy use.

  6. 4. Fluidized bed plants for heat and power production in future energy systems

    Author : Guillermo Martinez Castilla; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biomass combustion; combined heat and power; thermal power plant; process control; operational flexibility;

    Abstract : Fluidized bed (FB) plants are used for heat and power production in several energy systems around the world, with particular importance in systems using large shares of renewable solid fuel, e.g., biomass. READ MORE

  7. 5. New refrigerants for vapour compression refrigeration and heat pump systems : evaluation in a context of the requirements set by the F-gas Regulation and the Paris Agreement goals

    Author : Pavel Makhnatch; Rahmatollah Khodabandeh; Angelo Maiorino; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; refrigerant; retrofit; drop-in; HFC; HFO; F-gas Regulation; Kigali Amendment; Montreal protocol; Life cycle climate performance; LCCP; climate change; Energiteknik; Energy Technology;

    Abstract : Given the global commitment to reduce the impact of fluorinated gases on climate and the regulations controlling their use in the European Union (EU), this thesis investigates new refrigerants that have been recently proposed to meet the demands of the refrigeration industry in the EU, which must satisfy the legislative requirements of the F-gas Regulation and facilitate meeting the goals of the Paris Agreement.The legislative requirements of the EU have intensified refrigerant development with reduced GWP.
