ASHRAE has published guidance about the role of HVAC systems in helping to contain the coronavirus outbreak.
Its Covid-19 Preparedness Resources webpage, ashrae.org/COVID19, provides resources for building industry professionals, including the association’s position document on airborne infectious diseases.
ASHRAE president Darryl Boyce said: ‘Preparedness Resources are available as guidance to building owners, operators and engineers on how to best protect occupants from exposure to the virus, in particular in relation to airborne particles that might be circulated by HVAC systems.’
ASHRAE recommends dilution ventilation, laminar and other in-room flow regimes, differential room pressurisation, personalised ventilation, source-capture ventilation, filtration, and UVGI (upper room, in-room, and in the airstream).
CIBSE Healthcare Group was preparing its own guidance as CIBSE Journal was going to press. See cibse.org/coronavirus
