ANSI/AHRAE Addendum aa Brings Measurable Standards to IAQ

Download a Copy of Addendum aa!

The HVAC/R Industry saw the publication of Addendum aa to the ANSI / AHSRAE 62.1-2019 standard. Addendum aa allows for an alternative to standard Ventilation Rate Procedure calculations to allow for the IAQ Procedure (IAQP) as a means to maintain design compound concentrations and particulate matter (PM2.5) in indoor environments below design limits.

So – Now What?

Addendum aa set out to establish limits for certain compounds, particulate matter (PM2.5) and procedures that would be used to validate indoor design compound concentrations after the building is completed with the goal of ensuring occupant satisfaction. But how can the building occupants ensure that these levels are maintained post-completion?

Real-Time IAQ Performance Data Is Key!

Addendum aa exponentially increases the value of measuring IAQ parameters in real-time. Cubic Sensors & Instruments has the most complete portfolio of IAQ sensors – Particulate Matter (PM1.0, PM2.5 & PM10), Volatile Organic Compounds (VOC), Formaldehyde, Carbon Dioxide (CO2 ) and Carbon Monoxide (CO)- available to our Partners with the goal of ensuring they can respond to the new regulations faster than their competitors.

Innovative companies know that measuring these components will ensure their customers have peace of mind knowing that their buildings are performing to the design limits established when the building was first completed.
