Special Issue Information

Dear Colleagues,

Buildings are responsible for a large share of energy consumption and greenhouse gas emissions. Energy efficiency projects in the form of building retrofits can improve the energy performance of buildings and contribute to net-zero transition. As such, they are largely supported by current legislation such as the European Energy Performance of Buildings Directive. Off-site construction (OSC) is an interesting method for both retrofit and new construction projects, with several advantages over traditional construction methods. It involves the manufacture and pre-assembly of building components, elements, or modules prior to their installation in their final locations, ensuring significant quality as well as a reduction in time, costs, and environmental and social impact. Despite the benefits of OSC, its application is not globally uniform, and several challenges to its use can be identified, making a holistic understanding of this topic much needed. This Special Issue aims to provide a comprehensive and advanced overview of OSC, welcoming all research types (literature reviews and qualitative and quantitative research) from different geographical contexts. This Special Issue will include, but is not limited to, the following topics:

  • Barriers to and drivers of OSC;
  • OSC benefits;
  • OSC materials, including innovative and unconventional materials;
  • OSC solutions (components and elements);
  • Production process of OSC components and elements;
  • OSC value chain;
  • Digital OSC technologies;
  • Sustainability and OSC;
  • Circular economy and OSC;
  • Net-zero transition and OSC.

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 revised Energy Performance of Buildings Directive and Energy Efficiency Directive aim to accelerate the energy transition of the European building stock; however, progress remains insufficient. Off-site construction (OSC) and industrialised systems, such as Plug-and-Play (PnP) systems, are considered pivotal towards more efficient renovation practices. In this study, a PnP facade for building renovation—developed in an H2020 EU-funded research project—has been analysed with the following objectives: (i) benchmarking and assessing the construction process with a PnP facade system through the data gathered in two renovation scenarios, and (ii) identifying advantages and limitations related to implementing the technology. Two buildings—an early adopter in Budapest and a demonstration case in Pamplona—have been selected as renovation scenarios to validate the implementation of the system, testing different levels of technological integration and prefabrication. Key findings reveal that the PnP system offers significant advantages, including streamlined installation processes and reduced on-site waste compared to a conventional ventilated façade. However, the need for high workers’ tolerance, sensitivity, and precision during installation, as well as coordination protocols, has been highlighted to ensure a smooth implementation. This research contributes to the body of research on OSC technologies for building renovation, offering practical insights towards developing more sustainable construction practices. Full article
