REHVA published its first COVID-19 guidance mid-March 2020, followed by two updates in April (2nd version) and August 2020 (3rd version). The third version of the guidance is focusing on how to reopen and safely use buildings after the lockdown, providing advice on specific components, buildings/space types, and suggesting mitigation measures. The third version of the guidance document overwrites all previous ones. Updates are expected in the upcoming months as more academic data becomes available.
