ASHRAE Standard 170.1-2017 specifies both room and outdoor air change requirements for the mitigation of infectious disease. Continuous monitoring and control of airflow is required to ensure compliance.
Healthcare providers & patients need to be in the safest environment possible.
Title: The Importance of Controlled Ventilation in Schools
Abstract: Outdoor Air Ventilation in schools promotes health and wellbeing. Each individual requires a set amount of ventilation. The means to achieve ventilation is typically through mechanical HVAC systems. The minimum amount of ventilation required for schools is determined by state, provincial, and municipal codes. Many studies have determined that increased ventilation beyond the minimum may promote better health and improved performance. However, there is a cost to ventilation as it requires that the air be conditioned and filtered for the indoor environment. Therefore, efforts are made to reduce ventilation when the population in the building is reduced and when the building is unoccupied. Furthermore, the ventilation rate is impacted by the environment internal and external to the building, and by degradation and changes in the operation of the HVAC systems. The result is, the amount of actual ventilation is always subjected to dynamic changes and thereby a method to measure and control the ventilation should be integrated into every system to provide the desired correct and efficient ventilation rate.
