Air Ionization: Outdoor Air Reduction Makes Lots of (Dollars and) Sense!

During another of my recent presentations of the Aerisa air purification technology, a client asked, “If I clean the air within a facility’s admin area, can’t I reduce outdoor air and save on heating and cooling?”

Through use of the IAQ Procedure in ASHRAE Standard 62.1, “Ventilation for Acceptable Indoor Air Quality [IAQ],” outdoor air (OA) intake may be significantly reduced up to 66% when utilizing Aerisa’s ionization technology.  Facilities such as administrative offices, schools, churches, gyms, and auditoriums are all candidates – any place with lots of people.  By ionizing (cleaning) the air within the facility, OA required to dilute emitted pollutants may be greatly reduced.

When OA is reduced, the following compelling benefits are realized on new construction projects: 
  • Lower capital costs for heating and cooling equipment
  • Smaller ductwork, electrical service, roof penetrations and structural supports
  • Reduced installation costs
  • Reduced ongoing energy costs
  • Reduced project financing costs   
For existing AC systems or replacements, the ongoing energy savings will offset the cost of Aerisa ionization equipment in only a few years. 

Provided with some basic design information, Aerisa will return a full set of ASHRAE 62.1-2013 IAQ Procedure calculations documenting that resulting pollutant concentrations remain lower than acceptable levels.  A calculation example is shown below:

Aerisa’s ionization technology for commercial applications is based on ions produced by an ion generator, configured either with needlepoint brush electrodes or tubes.  These ion generators are mounted either inside a building’s air handler or on the supply ductwork.  Highly ionized air with millions of ions (O2+ and O2) are delivered in each cubic foot of air.  Because of their charge, these ions proactively oxidize the contaminants and agglomerate airborne particulate to vastly improve indoor air quality.  As a result, OA intake may be significantly reduced saving lots of money – it’s a no brainer!
