Revolutionize Ventilation Design: Unlock Energy Savings & ROI with the Indoor Air Quality Procedure

← Back to News

In our latest SVL Coffee Break Webinar, we had the pleasure of hosting Audwin “Audie” Cash, CEO of GPS Air. With over two decades of experience in energy-efficient solutions and product innovation, Audie brought valuable insights into the evolving world of indoor air quality (IAQ) and energy savings. His expertise spans multiple leadership roles, including serving as President of Climate Systems and Senior Vice President at Acuity Brands Lighting. Currently, Audie is focused on driving GPS Air’s post-pandemic growth with innovative products and robust market engagement.

A Shift in Air Quality Perception

Audie opened the discussion by highlighting a key shift in air quality perception. While IAQ was deemed essential during the pandemic, it has now transitioned back to being a “nice-to-have” for many. However, Audie emphasized that air quality technology, when positioned correctly, can deliver significant energy savings and real ROI, making it more than just a luxury.

ASHRAE Standards and the Evolution of GPS Air

A major focus of the webinar was how GPS Air has expanded beyond ionization technology. Historically recognized as an ionization-only company, GPS Air has broadened its portfolio to align with the latest ASHRAE standards. The company’s latest innovations prioritize energy efficiency while ensuring compliance with today’s stringent air quality regulations.

Audie detailed how ASHRAE has refined the Indoor Air Quality Procedure (IAQP), making it a viable and structured alternative to the traditional Ventilation Rate Procedure (VRP). The IAQP, when applied correctly, allows designers to reduce outdoor air intake by incorporating air cleaning technologies—resulting in substantial energy savings and optimized equipment performance.

Energy Savings and ROI Potential

One of the most compelling takeaways was the cost-saving potential of adopting IAQP. By reducing outdoor air intake and supplementing it with effective air cleaning, facilities can achieve:

  • Up to $2.00 per square foot in energy savings
  • 30-50% reductions in equipment costs for retrofitted buildings
  • Enhanced compliance with ASHRAE standards, reducing overall operational risks

Audie highlighted that IAQP is particularly beneficial in high-occupancy spaces such as schools, auditoriums, universities, and houses of worship. These spaces experience fluctuating occupancy rates, making them ideal candidates for adaptive air cleaning technologies.

Introducing SMART IAQ: A Dedicated Clean Air System

The webinar introduced SMART IAQ, GPS Air’s latest innovation. Designed as a parallel air cleaning system, SMART IAQ operates independently from HVAC systems to provide real-time air quality monitoring and purification. Key features include:

  • Advanced Solid-State Sensing: Continuously monitors IAQ and adjusts performance based on contaminant levels.
  • High-Efficiency Filtration: Removes PM2.5, VOCs, formaldehyde, and other pollutants.
  • ECM Blower Technology: Delivers clean air efficiently with low noise levels (NC27 in classroom settings).
  • Real-Time Performance Validation: Ensures compliance with ASHRAE standards and provides measurable results.

Seamless Integration and Smart MonitoringGPS-SMARTIAQ

SMART IAQ is designed for seamless integration with existing building systems. It offers:

  • Monitoring via MODBUS & BACnet: Ensures real-time tracking of air quality parameters.
  • On-Demand Operation: Activates and deactivates based on occupancy and contaminant levels.
  • Maintenance Indicators: Notifies users when filter replacements are necessary, reducing the risk of inefficiency.

Real-World Application and Results

Using real-world data, Audie demonstrated the effectiveness of IAQP through the GPS Air IAQP Calculator. This tool provides a side-by-side comparison of VRP and IAQP, illustrating the tangible benefits of reduced outdoor air intake and air cleaning. In a Minneapolis-based school case study, implementing IAQP led to:

  • 778 CFM reduction in outdoor air intake
  • $2,500 in annual energy savings per classroom cluster
  • Over $22,000 in first-cost savings through downsized HVAC equipment

Addressing Key Questions

During the Q&A, Audie addressed several insightful questions from the audience, including:

  • Sensor Reliability: SMART IAQ’s solid-state sensors self-calibrate and provide 10+ years of reliable data.
  • Filter Lifespan: Designed for at least one year in standard applications; high-contaminant areas may require more frequent replacement.
  • Sound Levels: Maintains a quiet operation with speeds adjusted based on occupancy and contaminant levels.
  • ASHRAE Compliance: Meets and exceeds ASHRAE 62.1 IAQP standards, making it a viable solution for sustainable building design.

Next Steps and Additional Resources

                      Al Gramse

                      Vice President of SVL Service Corporation

                      Al Gramse has been in the HVAC industry for over 30 years. He began as a service technician.  Then over his career worked in technical support, building automation, then service manager prior to his current role.

                      How did Al end up in the HVAC industry?  “After high school, I took a couple years to figure out what I wanted to do.   Where I was working at the time, a grumpy old coworker, who I didn’t get along with, walked up to me and said ‘What are you doing here?  Go back to school.’”  I said, “For what?”  He said “There’s a tech school down the street.  Go down there and pick something that interests you”. Then he walked away.  That weird interaction, with someone I didn’t get along with, sent me down a 30-year path in the HVAC industry.   Never underestimate the potential of a little encouragement.   Even if it is from a strange source.

                      Al has been with SVL for 15 years and is the head of our SVL Service division. “The people here are some of the best in the industry,” Al says. “A bunch of team-oriented, knowledgeable, go-getters.” His personal mantra is “figure it out,” “Do a little fact-finding on your own. Use your own brain before you use someone else’s. But know when to ask for help.” he prescribes. “It’s amazing what you can accomplish on your own if you dig in a little bit.”

                      Outside of work, Al has lots of outdoor hobbies, including hunting, fishing, and motorcycling, though his favorite pastime is simply hanging out with family.
