The Institute of Civil Engineers has announced that the Chartered Institution of Building Services Engineers (CIBSE), alongside the Scientific Advisory Group for Emergencies (SAGE), has published guidance on the subject of ventilation, safely re-occupying buildings, lift-use and occupancy, and the recommissioning of lifts and escalators amid the ongoing coronavirus (COVID-19) pandemic. The guidance, which is split into four documents, was launched as part of the CIBSE’s Emerging from Lockdown series.
