Why Air Quality Has Become a Tenant Retention Issue

As employers require employees to return to the office, workers are responding with some requests of their own. Namely, they care more about the physical environment more than most employers expected. According to the 2026 GPS Air indoor air quality survey, 61% of workers say they would choose a workplace with fresher, more comfortable air over one with better amenities for a full workday. A separate finding from the same survey shows that 38.4% of workers say the difference in comfort and air quality between their home and office directly affects their productivity.

With property owners trying to boost occupancy rates, and employers competing for talent, these new demands are occupancy risk factors. Employees are making decisions about where they do their best work, and the air they breathe is a major factor. In many cases, it’s more important than compensation packages and amenities.

Facility and operations leaders must respond by ensuring their building’s mechanical systems and documentation can meet these expectations.

IAQP and smartIAQ: Cut Outdoor Air Requirements Without Cutting Air Quality

The ASHRAE 62.1 IAQP pathway is a performance-based compliance alternative to the Ventilation Rate Procedure that turns active air cleaning into a direct capital and energy savings opportunity. Where VRP sets outside air requirements by peak occupancy, building type, and space area, IAQP allows commercial buildings to reduce mechanical outdoor air rates when active air cleaning is verified through monitoring and documentation. It results in immediate lower HVAC energy spend and smaller equipment specifications at the design stage. It also allows you to avoid the high costs and disruption that comes with structural changes during retrofits projects. The pathway has been part of ASHRAE 62.1 for 45 years and became significantly more prescriptive following updates in ASHRAE 62.1, 2019 through 2025, giving engineers a well-defined, standards-based framework to work within.

smartIAQ Technology

GPS Air’s smartIAQ closed-loop air cleaning platform is the enabling product for IAQP compliance in commercial office and mixed-use buildings. smartIAQ combines closed-loop monitoring, particle and carbon molecular filtration tested to ASHRAE 52.2 and 145.2 standards, and performance documentation in a single autonomous system. It integrates with building management systems via BACnet or Modbus, so IAQP performance data is part of routine building operations rather than a separate reporting burden. For a full comparison of VRP and IAQP ventilation design, see GPS Air's VRP vs. IAQP comparison table.

Use the smartIAQ Project Builder for Your Building

The smartIAQ Project Builder is a self-serve IAQP ventilation calculator built on ASHRAE 62.1 standards. Engineers use it directly to configure complete projects, model outdoor air reductions, and generate outputs suitable for drawings and specifications, with no contact required to get started.

smartIAQ By Space Type: Matching The Right Product To Your Floor Plan

Commercial office buildings rarely have uniform air cleaning needs across every space. Open floor plans, conference rooms, and multi-zone deployments each present different design challenges, and the right smartIAQ configuration depends on the space.

Large Open Floor Plans and Multi-Zone Spaces: smartIAQ Centralized

For whole-floor deployments and multi-zone office environments, the smartIAQ centralized configuration side-streams from an existing AHU to deliver IAQP-compliant air cleaning across multiple zones from a single unit. Closed-loop monitoring adjusts cleaning output continuously based on real-time contaminant levels. BACnet or Modbus integration puts air quality performance data inside the building management system alongside every other operational metric.

Conference Rooms and Single-Zone Spaces: smartIAQ GridSet™

In conference rooms HVAC systems are sized for peak occupancy in one room, which impacts equipment decisions for the entire floor. smartIAQ GridSet solves this by delivering IAQP-compliant air cleaning at the room level, independent of central HVAC. Each unit drops into a standard ceiling grid with no ductwork modification, runs on 48V DC low-voltage power over CAT-5 cable, and covers up to 1,500 square feet at approximately $2,000 per unit installed. CO2-based occupancy sensing means the unit idles when the room is empty and cleans when it is in use, extending filter life and avoiding the energy cost of conditioning outside air for a room that is rarely at capacity.

Addressing Odors, Particles, and Pathogens In Shared Spaces

GPS Air’s Needlepoint Bipolar Ionization (NPBI®) soft ionization technology addresses the odors, particles, and air quality conditions that employees and tenants experience throughout the building day.

In office and mixed-use environments, NPBI targets odors, fine particles, and certain airborne viruses and bacteria. In shared spaces, break rooms, lobbies, and multi-tenant corridors, odors generated by occupant activity and food preparation accumulate in ways that ventilation alone does not resolve. In high-traffic common areas, NPBI’s particle agglomeration effect helps particles cluster into sizes that standard filtration captures more efficiently, reducing the fine particulate load that recirculates through shared HVAC systems. For pathogen mitigation in occupied spaces, GPS Air’s third-party testing data is available at gpsair.com/resources/third-party-testing.

iMOD

GPS-iMod® for Odor Control and Coil Efficiency

GPS-iMod addresses inbound odors from outside air intakes and gradual coil fouling that degrades system performance.

On the odor side, cooking exhaust, diesel fumes, vehicle emissions, and smoke enter the building through outside air intakes and are distributed to every floor on that air handler. Changing filters and cleaning ducts rarely resolves the complaint because the source is upstream. GPS-iMod applies soft ionization at the AHU, reducing odors from vehicle exhaust, kitchen exhaust, smoke, and similar sources before they enter the ductwork and reach occupied spaces.

On the efficiency side, particulate and biological buildup on coil fins increases static pressure over time, forcing supply fans to work harder and consume more energy to maintain design airflow. GPS-iMod reduces the rate of that fouling, helping coils hold closer to design static pressure between service cycles and extending cleaning intervals.

WELL, LEED, and ESG: What GPS Air Supports

For building owners where certification influences leasing strategy or ESG commitments, GPS Air supports WELL Building Standard certification and LEED IAQP credit pathways. smartIAQ’s sensor data and air quality logs also provide the documented, timestamped record of indoor environmental conditions that ESG disclosure frameworks may require.

Case Study: GPS-iMod for Mixed-Use Odor Control

In mixed-use buildings where restaurant or food service tenants share mechanical systems with office tenants, cross-tenant odor is one of the most common and most damaging tenant complaint drivers. At 500 South College, a multi-tenant commercial building with a ground-floor Indian restaurant, cooking odors were being drawn into the building's outside air intake during peak lunch hours and distributed through the air handling system to upper-floor office tenants. GPS-iMod was installed directly on the existing air handler in a single afternoon, with no ductwork modifications and no disruption to any tenant. The fourth-floor tenant’s complaints stopped entirely.
