This work discusses recent developments in sharing economy concepts and collaborative co-design technology platforms applied in districts and cities. These developments are being driven both by new technological advances and by increased environmental awareness. The paper begins by outlining the state of the art in smart technology platforms for collaborative urban design, highlighting a number of recent examples. The case of peer-to-peer trading platforms applied in the energy sector is then used to illustrate how sharing economy concepts and their enabling technologies can accelerate efforts towards more sustainable urban environments. It was found that smart technology platforms can encourage peer-to-peer and collaborative activity, and may have a profound influence on the future development of cities. Many of the research and development projects in this area to date have focused on demonstrations at the building, neighbourhood, and local community scales. Scaling these sharing economy platforms up to the city scale and beyond has the potential to provide a number of positive environment impacts. However, significant technical and regulatory barriers to wider implementation exist, and realising this potential will require radical new approaches to the ownership and governance of urban infrastructure. This paper provides a concise overview of the state of the art in this emerging field, with the aim of identifying the most promising areas for further research.
La falta de información específica relativa al patrimonio edificado es uno de los factores que dificultan su gestión sostenible. Con el fin de promover una adecuada conservación y renovación de los edificios existentes, nuestro trabajo aborda el reto de mejorar el conocimiento sobre edificios existentes, poniendo el foco en sus fachadas. Este artículo presenta el desarrollo de una colección de fichas, con datos clave sobre los sistemas constructivos, para caracterizar las tipologías constructivas más habituales en fachadas del patrimonio edificado español. La colección de fichas recopila, de manera sistemática, información técnica sobre dichos sistemas, con datos relativos a sus prestaciones, propensión a lesiones y capacidad de mejora. Planteadas para poder adaptarse a formatos digitales a fin contribuir a implementar bases de datos holísticas e interoperables en BIM, las fichas de clasificación se diseñaron para ser manejables y adaptables, contemplando su aplicación en trabajos de inspección y diagnóstico de edificios existentes.
Existing buildings play a central role in achieving EU climate and energy targets. Consequently, the building sector faces the complex challenge of finding effective solutions to manage both the conservation and renovation of this stock. Given that building energy renovation has the potential to reduce greenhouse gas emissions and achieve EU targets, the European Commission has developed frameworks and regulatory instruments to foster a deep renovation approach. However, progress in achieving the necessary transformation has been slow. The objective of this chapter is to identify strategies and actions that can accelerate the sustainable transformation of the building stock. We focus on the first renovation stage in which it is critical for accurate data to be collected and processed on the state of buildings to improve decision-making processes. By overviewing current policies and instruments, and new technologies and tools applicable to existing buildings, we explore open challenges and room for improvement to fulfil their potential. In this study, we have identified upgraded instruments and tools and new benchmarks, resulting in innovative strategies and actions as drivers for a sustainable transformation. From this perspective, we introduce how more ambitious approaches can lead stakeholders to develop strategies and apply actions towards a regenerative built environment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
