  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. District heating in future Europe : Modelling expansion potentials and mapping heat synergy regions

    Author : Urban Persson; Sven Werner; Lars J. Nilsson; Sweden Gothenburg Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; district heating; energy efficiency; distribution capital cost; heat demand density; plot ratio; excess heat recovery; sequential energy supply; heat utilisation rate; effective width;

    Abstract : This thesis presents a set of methodologies and approaches to investigate and determine the extent by which district heating can contribute to improved energy system efficiency and reduced carbon dioxide emissions in future Europe. The main motivation for suggesting large-scale implementation of district heating as a structural energy efficiency measure to obtain these objectives originates essentially in the predicament that a majority of European buildings today remain highly dependent on fossil fuels to provide energy needed for space heating and hot water preparation.

  5. 3. Energy transition in transportation : Applying TIMES-based energy system optimisation models to sub-national levels

    Author : Jonas Forsberg; Anna Krook-Riekkola; Andrea Toffolo; Åsa Lindman; Krister Sandberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy system analysis; ESOM; Transportation; Climate change; Air quality; Energy Engineering; Energiteknik;

    Abstract : Transportation is embedded in the fabric of society and a key enabler of socio-economic development, but it is also a major source of carbon dioxide (CO2) and local air pollution (AP). Cities collectively account for around three quarters of total energy-related CO2 emissions, and the negative health impacts from local APs are most felt in dense urban environments. READ MORE

  6. 4. Influences from Building Energy Efficiency Refurbishment on a Regional District Heating System

    Author : Tina Lidberg; Louise Ödlund; Thomas Olofsson; Urban Persson; Högskolan i Gävle; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; District heating; energy efficiency; building refurbishment; greenhouse gases; primary energy; Fjärrvärme; energieffektivitet; byggnadsrenovering; växthusgaser; primärenergi; Hållbar stadsutveckling; Sustainable Urban Development; Reesbe företagsforskarskola;

    Abstract : Improving energy performance of existing buildings is an important part in decreasing energy use and in turn reduce the greenhouse gas emissions caused by human activity and the primary energy use.To be able to evaluate how energy refurbishment influences the greenhouse gas emissions and the primary energy use a wider system perspective is needed that puts the building in its context.
