Special Issue Information
Dear Colleagues,
In total, 40% of global CO2 emissions are from the building sector, and 60% of the total consumed energy in buildings is attributed to heating, ventilation, and air conditioning (HVAC) systems. Geothermal heat pumps (GHP) take advantage of the relatively constant temperature of the Earth to become highly efficient by exchanging heat with the Earth through a ground heat exchanger, allowing 20–70% of energy consumption reduction compared to conventional HAVC systems.
Nowadays, GHPs are considered as the spearhead of geothermal energy worldwide. The growth rate of the global GHP installed capacity was over 8% in the last decade, and it accounts for nearly 60% of geothermal direct use. Such an impressive development pace could not have been achieved without technology advances through different research in system designing, component modelling, controlling strategy, and optimization of thermal efficiency. The research and application of GHP systems is a multidisciplinary practice, involving complex thermal–hydrodynamic–mechanical–chemical coupled processes and governing mechanisms. The continuous development and application of GHP systems require innovative thinking and tremendous communication among different areas.
This Special Issue aims to gather original experimental, theoretical, and numerical research articles to present and disseminate the most recent advances related to the theory, experimentation, design, modelling, application, construction, and monitoring of geothermal heat pumps and ground heat exchangers. Topics of interest for publication include, but are not limited to:
- Effective and affordable site investigation technologies used in complex hydrogeological environments;
- High-efficiency drilling technologies;
- Advanced backfilling materials;
- Optimization of working fluid;
- Coupled thermal–mechanical–fluid behaviours of heat exchangers and the ground;
- Dynamic monitoring, modelling, and prediction of ground temperature, hydrological, and mechanical fields;
- Integrating heat pumps and ground thermal/cold storage in energy districts;
- Application of geothermal heat pumps beyond the building sector;
- Environmental impacts and evaluation of geothermal heat pump systems;
- Smart, multi-source systems based on geothermal heat pumps.

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. Energies 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 2600 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.
