Dear Colleagues,

Heat remains the largest energy end-use, constituting 50% of global energy consumption in 2018, which contributed to 40% of the global CO₂ emissions according to the International Energy Agency. That heat was mainly used for industrial processes (50%), buildings space and water heating (46%), and to a lesser extent for agriculture use and cooking. Despite the larger penetration of renewable energy, only 10% of the total heat demand is being covered by renewable sources (excluding biomass). Regarding the electricity share of energy resources, thermomechanical energy conversion is still predominant regardless of whether it comes from traditional fossil fuel power plants, nuclear energy or renewables such as biomass, solar thermal energy and geothermal. Projected scenarios on worldwide energy demand estimate an extensive penetration of renewable energy sources seeking to mitigate climate change consequences. In that context, developing highly efficient heat and power thermal energy systems will be crucial for sustainable development.

Noting all these exciting developments, it has never been more pertinent to launch a Special Issue that seeks to capture the latest research in thermal energy modelling with a clear interest in thermodynamics optimization, advanced thermal conversion systems, buildings’ energy efficiency and heat transfer characterization, regardless of whether it is for heat generation or electricity production for renewable energy applications.

Authors are encouraged to submit their research for this Special Issue. Topics include but are not limited to:

• Thermodynamics optimization
• New concepts in thermodynamics cycles
• Hybrid thermal energy applications modelling
• Combined cooling, heat and power modelling
• Waste heat recovery applications
• Thermal energy storage modelling
• Solar thermal energy applications
• Geothermal applications
• Heat transfer characterization in renewable energy applications
• Advanced concepts for heat exchangers modelling and design
• Heat pumps modelling
• HVAC modelling
• Energy management in buildings
• Computational fluid dynamics (CFD) for thermal energy applications

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. Thermo is an international peer-reviewed open access quarterly 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 1000 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.
