1. 1. Restructured district heating price models and their impact on district heating users

   Författare :Jingjing Song; Björn Karlsson; Fredrik Wallin; Hailong Li; Heimo Zinko; Mälardalens högskola; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; district heating; restructured price model; price model survey; pricing strategy; consumption profile; consumption pattern; alternative cost; Energy- and Environmental Engineering; energi- och miljöteknik;

   Sammanfattning : District heating (DH) is considered to be an efficient, environmentally friendly and cost-effective method for providing heat to buildings, since electricity is usually co-generated in biomass fuelled combined heat and power (CHP) plants. This gives it an important role in the mitigation of climate change. LÄS MER

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

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

   Sammanfattning : 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.

4. 3. Importance of the demand-supply balance in district heating systems

   Författare :Dmytro Romanchenko; Chalmers University of Technology; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optimisation; thermal energy storage; buildings; district heating; Space heating; flexibility; demand response;

   Sammanfattning : In line with global efforts directed against climate change, the building sector will have to undergo significant changes in terms of its energy use, along with the transformation of the energy system. The scope of this thesis is limited to the energy supply and demand within district heating (DH) systems, with the emphasis on the space heating demand in buildings. LÄS MER

5. 4. Building Energy Efficiency Measures in District Heating Systems

   Författare :Tina Lidberg; Louise Ödlund; Thomas Olofsson; Erik Dahlquist; Högskolan i Gävle; []
   Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; building simulation; combined heat and power; district heating; domestic hot water; energy efficiency; greenhouse gas emission; low-temperature; multi-family building; primary energy; refurbishment; byggnadsimulering; energieffektivitet; flerfamiljshus; fjärrvärme; kraftvärme; lågtemperatur; primärenergi; renovering; tappvarmvatten; växthusgas; Hållbar stadsutveckling; Sustainable Urban Development; Reesbe företagsforskarskola; Reesbe företagsforskarskola;

   Sammanfattning : Improving energy performance of existing buildings is an important part in decreasing energy use and in turn reducing greenhouse gas emissions and primary energy use. To be able to evaluate how energy refurbishment influences greenhouse gas emissions and primary energy use a wider system perspective is needed which puts the building in its context. LÄS MER

7. 5. The Business Model - Formation, description and definition

   Författare :Jon Williamsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; business model; market based instruments; cleantech; stakeholder inclusion; sensemaking; narratives; district heating; prgmatism; communicative theory of the firm;

   Sammanfattning : The business model is a new analytical concept in the field of strategy research that is frequently used when trying to explain the creation and capture of value by firms. This compilation thesis consists of three papers that examine different aspects of the formation of business models and one paper that examines the business model concept per se. LÄS MER
