Special Issue Information

Dear Colleagues,

Energy resource consumption has doubled since the beginning of the century, and the demand growth with the fast development in industrial and telecommunication sectors. Responding to the rising demand for energy resources, new efficient infrastructures for production, storage, transport, and use of energy are necessary. The International Conference on Innovative Applied Energy (IAPE’19) aims to investigate innovative applications and latest research in the areas of energy production, alternative and renewable energy supply, energy savings analysis, optimization of energy processes, and the environmental impacts of energy production.

This year, the IAPE Annual Conference was held on 14–15 March, 2019, at the King’s Centre, Oxford, United Kingdom and has been supported by Entropy. This is an international journal dealing with the development and/or application of entropy or information–theoretic concepts in a wide variety of applications (for more details, see: https://www.mdpi.com/journal/entropy/about). Thus, this Special Issue will collect the most relevant papers dealing with entropy and information theory-based applications presented in this conference.

Hence, we encourage the authors who have presented an article at IAPE’19 and who feel that their contribution is within the scope of interest of the journal Entropy to apply through the following link: https://susy.mdpi.com/. The selected authors will be asked to submit an original and essential extension of the IAPE paper to be considered for publication no later than December 1st. More details can be found at https://www.mdpi.com/journal/entropy/instructions#preparation. The accepted papers, after a normal process of peer-review by experts in the field of applied energy, will be published in Entropy.

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 papers will be 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. Entropy is an international peer-reviewed open access monthly 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 1600 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.

The paper addresses an important long-standing question in regards to the energy efficiency renovation of existing buildings, in this case hotels, towards nearly zero-energy (nZEBs) status. The renovation of existing hotels to achieve a nearly zero-energy (nZEBs) performance is one of the forefront goals of EU’s energy policy for 2050. The achievement of nZEBs target for hotels is necessary not only to comply with changing regulations and legislations, but also to foster competitiveness to secure new funding. Indeed, the nZEB hotel status allows for the reduction of operating costs and the increase of energy security, meeting the market and guests’ expectations. Actually, there is not a set national value of nZEBs for hotels to be attained, despite the fact that hotels are among the most energy-intensive buildings. This paper presents the case study of the energy retrofit of an existing historical hotel located in southern Italy (Syracuse) in order to achieve nZEBs status. Starting from the energy audit, the paper proposes a step-by-step approach to nZEBs performance, with a perspective on the costs, in order to identify the most effective energy solutions. Such an approach allows useful insights regarding energy and economic–financial strategies for achieving nZEBs standards to highlighted. Moreover, the results of this paper provide, to stakeholders, useful information for quantifying the technical convenience and economic profitability to reach an nZEBs target in order to prevent the expenses necessary by future energy retrofit programs.
