Special Issue Information

Dear Colleagues,

I would like to invite you to submit your latest research findings in Thermal Management of Urban Subsurface Resources to a Special Issue of Sustainability (ISSN 2071-1050), an open access journal (https://0-www-mdpi-com.brum.beds.ac.uk/journal/sustainability). Submissions should include studies that advance the current state of knowledge or critical reviews of existing models and practices.

The use of shallow subsurface resources is a practice of optimization and energy sustainability that is currently experiencing an exponential increase in urbanized areas, homes, industries, and centers for different services and therefore needs rational management guidelines based on the state of knowledge in this field. This Special Issue aims to collect recent research on the thermal management of urban subsurface resources, including, but not limited to, the following themes: (I) technologies of groundwater use that could take advantage of urban resources for energy supply; (II) modeling of heat flow in urban aquifers and analysis of the exploitation impacts of energy resources; (III) proposals for guidelines for a rational and sustainable management of heat sources in urban aquifers; (IV) effects of heat exchange with annual seasonality; heat extraction/injection cycles in urban aquifers; (V) actual or predictive analysis of the negative effects produced by poor management and overexploitation of the heat resources of groundwater in urban areas; and (VI) long-term predictive stationary or nonstationary models of the effects of the exploitation of subsurface thermal resources. I also encourage submissions on case studies of thermal management of urban subsurface resources even when they have a multidisciplinary character due, for instance, to the mobilization of pollutants due to the processes of temperature change and/or reactivation of the movement of groundwater in contaminated soils.

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. Sustainability 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.

The long-term sustainability of shallow geothermal systems in dense urbanized areas can be potentially compromised by the existence of thermal interfaces. Thermal interferences between systems have to be avoided to prevent the loss of system performance. Nevertheless, in this work we provide evidence of a positive feedback from thermal interferences in certain controlled situations. Two real groundwater heat pump systems were investigated using real exploitation data sets to estimate the thermal energy demand bias and, by extrapolation, to assess the nature of thermal interferences between the systems. To do that, thermal interferences were modelled by means of a calibrated and validated 3D city-scale numerical model reproducing groundwater flow and heat transport. Results obtained showed a 39% (522 MWh·yr−1) energy imbalance towards cooling for one of the systems, which generated a hot thermal plume towards the downgradient and second system investigated. The nested system in the hot thermal plume only used groundwater for heating, thus establishing a positive symbiotic relationship between them. Considering the energy balance of both systems together, a reduced 9% imbalance was found, hence ensuring the long-term sustainability and renewability of the shallow geothermal resource exploited. The nested geothermal systems described illustrate the possibilities of a new management strategy in shallow geothermal energy governance. Full article
