Special Issue Information
Dear Colleagues,
It is well known that district heating and cooling (DHC) networks for urban environments can provide energy savings with significant economic and environmental benefits, among others, with respect to individual building heating and cooling facilities. Therefore, many studies and reviews have been done in this field. However, this new Special Issue will not only cover the main features of DHC networks and their current state-of-the-art but will focus mainly on new advanced features, such as:
- Analysis of new cogeneration, trigeneration, and polygeneration configurations to supply energy for DHC networks. Special attention will be given to renewable based DHC networks using several energy resources such as solid biomass and urban waste residues, solar energy, geothermal, etc., making use of several energy conversion technologies, and also with the possibility to favorably contribute to a more sustainable mobility in cities;
- Low and very low distribution temperature networks known as the fourth generation of DH networks;
- Integration of compression and sorption heat pumps using new configurations for the simultaneous delivery of heating and cooling, both at the energy supply plant and/or as substation units;
- Use of urban heat sources such as the recovery of heat from underground transport facilities, sewage water networks, etc. for their use in DHC networks;
- New DHC technologies for small villages with high-energy demand and costly access to energy grids using local resources to contribute to the local economy growth by the promotion of the employment and settlement of rural population.
The use of renewable energy sources, recovered heat from urban or industrial waste, cooling from regasification plants, new low temperature distribution networks, and synergies with electricity and gas fuel networks are paving the way to the new concept of a smart energy system with a higher scope than the usual smart grid concept limited to the electricity grid. The aforementioned and many other new developments will help to widely spread the implementation of DHC networks, especially for the case of cooling supply that is currently less developed, and at the same time contribute in this way to achieve the internationally agreed commitments on the environment and climate change.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Applied Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2400 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Benefits of Publishing in a Special Issue
- Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
- Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
- Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
- External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
- e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.
