ASHRAE Epidemic Task Force Releases Updated Building Readiness Guide

L’American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) a mis à jour le guide de bonnes pratiques d’entretien du système de chauffage, de ventilation et de climatisation (CVC) des immeubles afin de prévenir la transmission du virus SRAS-CoV-2. Les informations mises à jour portent, entre autres, sur les calculs du nettoyage à effectuer avant ou après l’occupation de l’immeuble afin de réduire le temps et l’énergie nécessaires.

As the performance of many HVAC systems in buildings are still being evaluated, the ASHRAE Epidemic Task Force has updated its reopening guidance for HVAC systems to help mitigate the transmission of SARS-CoV-2. “The Building Readiness Guide includes additional information and clarifications to assist designers and commissioning providers in performing pre- or post-occupancy flush calculations to reduce the time and energy to clear spaces of contaminants between occupancy periods,” said Wade Conlan, ASHRAE Epidemic Task Force Building Readiness team lead. “New information includes the theory behind the use of equivalent outdoor air supply, method for calculating the performance of filters and air cleaners in series, and filter droplet nuclei efficiency that help evaluate the systems’ ability to flush the building.”
