Special Issue Information

Dear Colleagues,

Considering the ever-growing importance of sustainable energy solutions and need for efficient, eco-friendly energy utilization within the built environment, increasing interest in hybrid renewable energy systems within this environment has emerged. Buildings play a significant role in the energy cycle and sustainability, and the integration of various energy generation and storage technologies is regarded as promising for efficient and sustainable energy systems.

This Special Issue of Energies (IF = 3.2; CiteScore: 7.3), entitled "New Insights into Hybrid Renewable Energy Systems in Buildings", focuses on exploring advancements in the integration of hybrid renewable energy systems within the built environment. We welcome original research, studies, and reviews covering various aspects of this topic, including, but not limited to, the following:

  • Integration of diverse renewable energy generation technologies in the building context.
  • Innovative control strategies for optimizing the performance of hybrid energy systems.
  • Integration and management of energy storage systems within building structures.
  • Synergy between electrical mobility solutions and buildings.
  • Advances in energy storage and conversion technologies.

Submissions to this Special Issue will undergo a rigorous peer-review process.

Researchers, experts, and practitioners are encouraged to submit their original work to this Special Issue. We are looking forward to receiving your contributions.

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 250 words) can be sent to the Editorial Office for assessment.

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-anonymized 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.

Proximity-Based Food–Energy–Water (FEW) Integration in a Neighborhood-Scale Montreal Case Study

Abstract
Abandoned and underutilized buildings/spaces exhibit considerable potential to transform into resource-producing hubs (RPHs) by integrating food–energy–water (FEW) systems. The Pointe-Saint-Charles neighborhood is used as a representative case study for FEW incorporation and proximity-oriented developments (PODs).

Abandoned and underutilized buildings/spaces exhibit considerable potential to transform into resource-producing hubs (RPHs) by integrating food–energy–water (FEW) systems. The Pointe-Saint-Charles neighborhood is used as a representative case study for FEW incorporation and proximity-oriented developments (PODs). A scalable food–energy–water + proximity-oriented development (FEW–POD) framework is developed to integrate retrofitting strategies in an existing neighborhood. Food is cultivated through urban agriculture (UA), energy is produced using solar photovoltaics (PVs), and rainfall is harvested to support irrigation. Resource-sharing networks (RSNs) are developed to improve availability and accessibility to food items. A scenario-based assessment is performed, where Scenario 1 (S1) includes baseline resource demand assessment, Scenario 2 (S2) integrates FEW, and Scenario 3 (S3) distributes food items within the neighborhood, from surplus to deficit neighborhood units (NUs) by developing RSNs. The Food–Energy–Water–Carbon Index (FEWCI) is developed to estimate contributions to resource needs and carbon emission reductions. It is based on food self-sufficiency (FSS), energy self-sufficiency (ESS), and water self-sufficiency (WSS), and avoids carbon emissions from food miles and the grid. Carbon emissions from food miles and the grid are reduced by 96% and 27.5%, respectively, from S1 to S2, but remain unchanged in S3 as no extra food or energy is being produced. The estimation of ESS and grid-based carbon emissions excludes the energy demand associated with greenhouse operations, as incorporating this will reduce energy and carbon benefits. The neighborhood’s FEWCI is improved to 0.40 by bringing in FEW production and to 0.66 by distributing food items among NUs. Full article
