As mentioned in our January blog post, 2022 marks the 50-year anniversary of Trane’s Engineers Newsletter publication! This month we hear from a frequent EN author, Trane Applications Engineer John Murphy.
Ventilation has been used in buildings for much, much longer than air conditioning has been around. Even so, the world was reminded of the importance of proper ventilation in buildings during the recent pandemic.
Ventilation can be used to help improve indoor air quality. For decades, engineering professionals who design HVAC systems have looked to industry standards and codes for minimum ventilation requirements. And while this year marks the 50-year anniversary of Trane’s Engineers Newsletter, next year will mark 50 years since the initial publication of ASHRAE® Standard 62.1, one of the foundational standards used for designing ventilation systems.
Over the years, several ENs have been published to discuss ventilation practices and strategies. Some issues explained the requirements of Standard 62.1, including both the Ventilation Rate Procedure and the IAQ Procedure. Other issues described emerging ventilation design strategies—such as dedicated outdoor-air systems, displacement ventilation, or underfloor air distribution—and ventilation control strategies—such as demand-controlled ventilation or ventilation reset in a multiple-zone VAV system. And then more recently, we used the EN to share the ASHRAE® Epidemic Task Force’s recommendations for operating HVAC systems during the COVID-19 pandemic.
Included below are links to a few of the past ENs related to ventilation strategies, in case you missed them:
