Lessons learned

  • The need of both national and European platform about sustainable building has been confirmed by building stakeholders. The national scale is the more relevant to collect contents: professionals need to share information and promote their innovative realizations with peers belonging to the same market and using the same language. The European scale is an additional benefit, offering a larger perimeter for promotion of innovative solutions and a window of the best practices from other countries.
  • The need of a web platform to accelerate best practices dissemination about sustainable building has been clearly confirmed by all professionals. Nevertheless, due to the low usage level of social networks with in the building community, it has been necessary to develop personalized training and assistance to help Construction21 early adopters to handle the tool, identify the benefits they could get from it and integrate it progressively in their professional habits.
  • Competition engine is a powerful tool to incite building professionals to share information with their peers. Construction21 team has experienced that with the Sustainable Urban Building Awards 2013. The perspective of a large visibility of their realizations on the 7 Construction21 platforms and all the media which have relayed the information has incited numerous professionals to enter their most performing buildings in Construction21 database, adding 100 new case studies in a few weeks.
