Rodríguez Álvarez, JorgeSoares Gonçalves, Joana Carla2026-02-252021-03-042021-03-01978849749794710.17979/spudc.9788497497947https://pepa.une.es/handle/123456789/65481The organization of the 35th PLEA Conference has been an enormous challenge. The unprecedented circumstances that preceded it required flexible and, at the same time, determined decision making. Once finished, we hope that PLEA 2020 becomes a landmark in the longstanding and unique trajectory of PLEA. It has been its first virtual Conference; arguably, the one with the lowest carbon footprint (which is being calculated by some participants). The organizational expenses were lower than those for a physical conference, which allowed for a substantial reduction in the participation fees. According to the participants’ comments and feedback, the event was quite satisfactory. The environment was, overall, dynamic and engaging, the debate was fluid and there were numerous opportunities for interaction, considering the limitations. The high quality of the technical presentations was one of the most important factors, as they kept ongoing attention during the three days. The keynote speakers brought fresh and diverse ideas to the discussion. The roundtables were often enriched with the comments and remarks from the participants, enhancing direct interaction with the speakers as well as among themselves.Libro digitalCreative Commons Attribution 4.0 International (CC BY 4.0)http://creativecommons.org/licenses/by/4.0/El medioambienteopenAccessPLEACarbonCitiesarchitectureConstrucción de edificios y materialesArquitectura
