De oversete mennesker i randområderne

Jan Kloster Staunstrup & Jørgen Møller
I planlægningen og reguleringen af rammevilkårene for livet uden for de større byer, er der mange udfordringer. Vi vil i denne artikel se nærmere på nogle af dem, der knytter sig til den manglende præcision i definition af landdistriktsbegrebet, samt komme med bud på praktiske og teoretisk baserede overvejelser, der kan bidrage til at løse disse.

Kantian grammar applied to French, English, Danish and some other languages

Hanne Korzen
Many linguists refer to Kant, but they do not really seem to take him seriously. I will try to show that a little closer look at Kant's cognitive model might yield insight into certain important aspects of the syntactic-semantic constitution of the sentence in different languages. I will also show that Hamann, Herder and their many followers are completely wrong in arguing that Kant's model was influenced by his own language without himself knowing it....

How can the concept of networks contribute to understanding the role of households in crises where ICT infrastructure fail? ICT infrastructures are large-scale techno-material networks crucial to modern human social organisation and living. They play a role in connecting individuals to households and individuals and households to their wider surroundings. Drawing on fieldwork from a recent crisis in Norway, this article uses actor-network theory (ANT) as an analytical lens. The aim is twofold; firstly to...

Fieldwork

Bent Sørensen
This article examines some aspects of the phenomenon of popular fiction, using the terminology proposed by Pierre Bourdieu in his works on distinction and cultural production, including ‘position taking,’ ‘field,’ and ‘capital(s).’ After the theoretical groundwork is laid, the second half of the article analyzes specifically the case of popular postmodern author Paul Auster, with regards to the role of genre and dual readership/reading protocol inscribed in his fictions, the mechanisms of gatekeeping, consecration and...

Energy Systems Modelling Research and Analysis

Frits Møller Andersen & Poul Alberg Østergaard
This editorial introduces the seventh volume of the International Journal of Sustainable Energy Planning and Management. The volume presents part of the outcome of the project Energy Systems Modelling Research and Analysis (ENSYMORA) funded by the Danish Innovation Fund. The project carried out by 11 university and industry partners has improved the basis for decision-making within energy planning and energy scenario making by providing new and improved tools and methods for energy systems analyses.

Classification through analytic hierarchy process of the barriers in the revamping of traditional district heating networks into low temperature district heating: an Italian case study

Marco Pellegrini, Augusto Bianchini, Alessandro Guzzini & Cesare Saccani
The revamping of existing high temperature district heating systems with low temperature solutions will ensure a better usage of primary energy thanks to the reduction of thermal losses through the networks and to the possibility of use low grade enthalpy heat for the scope, including renewables and waste heat. However, several criticalities are present that make the evolution from the 3rd to the 4th generation of district heating not immediate. The paper aims to identify...

Modelling framework for integration of large-scale heat pumps in district heating using low-temperature heat sources

Henrik Pieper, Vladislav Mašatin, Anna Volkova, Torben Ommen, Brian Elmegaard & Wiebke Brix Markussen
The paper presents a modelling framework that may be used to plan the integration of large-scale HPs in district heating (DH) areas. By use of the methodology both optimal HP capacities to be installed and optimal choice of heat source to be used during the year are identified by minimizing total cost of ownership including investment and operational costs. The modelling framework uses mixed-integer linear programming and hourly calculations over one year. Seasonal variations of...

Method for addressing bottleneck problems in district heating networks

Lisa Brange, Kerstin Sernhed & Marcus Thern
To work with lowering the system temperatures in district heating (DH) grids is an important factor for system efficiency. Lower system temperatures are related to for example heat losses and production unit efficiency. One obstacle to lower supply temperatures are so called bottlenecks in DH networks. Bottlenecks are areas in the DH network that have very low differential pressure, which makes it difficult to supply them with enough heat. There are many possible solutions to...

Development of a user-friendly mobile app for the national level promotion of the 4th generation district heating

Anna Volkova, Eduard Latõšov, Vladislav Mašatin & Andres Siirde
The consumers are considered to play one of the most significant roles in the district heating transition process towards the 4th generation. Unfortunately, the lack of information and widespread consumer ignorance of interconnections and dependencies in the district heating system can lead to a situation where consumers are not interested in the development of the district heating system, or might even choose other heat sources. One of the possible solutions to provide information and educate...

A multi-objective optimization analysis to assess the potential economic and environmental benefits of distributed storage in district heating networks: a case study

Roberta Roberto, Raffaele De Iulio, Marialaura Di Somma, Giorgio Graditi, Giambattista Guidi & Michel Noussan
Conventionally, district heating networks have been developed with a centralized logic, with large generation units designed to provide space heating to distributed users. Some networks have already evolved to a stage in which multiple generation units are distributed throughout the network and are supplying heat from different sources and with different schedules. ICT technologies can be the basis for a live optimization of the network, which can be implemented by minimizing energy supply cost for...

Developments in 4th generation district heating

Poul Alberg Østergaard, Henrik Lund & Brian Vad Mathiesen
This editorial introduces the 20th volume of the International Journal of Sustainable Energy Planning and Management. Papers included are all from the conference on 4th generation District heating and Smart Energy Systems, Aalborg, 2017, treating the control of heat systems, technical and non-technical barriers to low-temperature district heating. Temperature levels are also key-parameters in an investigation of heat pumps and heat sources for heat pumps in Tallinn. In parallel to apps focusing on electricity systems,...
