  2. 1. A Silent Revolution : The Swedish Transition towards Heat Pumps, 1970-2015

    Author : Petter Johansson; Pär Blomkvist; Martin Vendel; Eric Giertz; Mats Fridlund; KTH; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; heat pumps; socio-technical transition; sustainability transition; industrial dynamics; value networks; coopetition; complementarities; strategic management; värmepumpar; socio-tekniska övergångar; hållbarhet; industriell dynamik; värdenätverk; coopetition; komplementariteter; företagsstrategi; Industriell ekonomi och organisation; Industrial Economics and Management;

    Abstract : Currently, more than half of all Swedish single-family houses have an installed heat pump and more heat is supplied by heat pumps in Sweden than in any other nation. Despite the enormous impact of heat pumps on the Swedish energy system, the transition towards their use has gone relatively unnoticed. READ MORE

  4. 2. A co-simulation based framework for the analysis of integrated urban energy systems : Lessons from a Swedish case study

    Author : Monica Arnaudo; Björn Laumert; Monika Topel; Louise Ödlund; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Technology; Energiteknik;

    Abstract : As major responsible for CO2 emissions, the energy sector is urgently called to take action against climatechange. The integration of renewable energy resources is a solution that, however, comes with a challenge.In fact, renewables are often variable, unpredictable and distributed. READ MORE

  5. 3. Exploiting the Synergies from Coupled Electricity and Heat Distribution Networks : Modelling, simulation and optimization based on an extended energy hub approach

    Abstract : Recent literature shows that there is a significant potential of decarbonisation and efficiency improvement that can be achieved through the synergy from multi-energy systems (MESs). Coupling technologies, such as co-generation plants, heat pumps and thermal storages are widely recommended as means of unlocking additional flexibility and increasing the penetration of renewables in the heating and electricity sectors.

  6. 4. Energy Efficient Renovation Strategies for Swedish and Other European Residential and Office Buildings

    Author : Marcus Gustafsson; Sture Holmberg; Jonn Are Myhren; Chris Bales; Jarek Kurnitski; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy efficiency; renovation; low-temperature heating; air heat recovery; district heating; heat pump; Energieffektivitet; renovering; lågtemperaturuppvärmning; värmeåtervinning; fjärrvärme; värmepump; Byggvetenskap; Civil and Architectural Engineering; Energy and Built Environments;

    Abstract : The high energy use in the European building stock is attributable to the large share of old buildings with poor energy performance. Energy renovation of buildings is therefore vital in the work towards energy efficiency and reduced environmental impact in the EU. READ MORE

  7. 5. Energy efficiency measures in the built environment - some aspects to consider in Sweden

    Author : Mattias Gustafsson; Björn O. Karlsson; Mats Rönnelid; Louise Ödlund; Jan-Olof Dalenbäck; Högskolan i Gävle; []
