smartIAQ GridSet: Compliance Without Complication

smartIAQ® GridSet enables ASHRAE 62.1 IAQP compliance for classrooms, offices, banks, and other commercial spaces by delivering verified in-room air cleaning without modifying existing HVAC infrastructure. It lays directly into a standard ceiling grid, runs on 48 VDC low-voltage power over CAT-5 cable, and generates closed-loop monitoring data.

For engineers and facilities directors working within tight mechanical budgets, smartIAQ GridSet provides a path to IAQP compliance that doesn’t require reworking the ceiling or the ductwork.

 

 

  • 150 CFM nominal clean-air delivery per unit
  • Whisper-quiet operation at NC-25 maximum
  • Simple lay-in ceiling grid installation, no ductwork required
  • 48 VDC low-voltage power delivered over CAT-5
  • Complete filter for particles, VOCs & formaldehyde (20" x 20" x 2")
  • LED status and closed-loop monitoring with service indication

How smartIAQ GridSet Delivers Ventilation Efficiency

Clean at the source

Air is cleaned in the room, reducing the amount of outdoor air the HVAC system must condition.

Operate on demand

The unit ramps up when rooms are occupied and conserves energy and filter life when they are empty.

Verify performance

Closed-loop monitoring provides clear evidence that targets are being maintained and signals service only when needed.

smartIAQ GridSet installs directly into a standard ceiling grid with no tile removal or line-voltage electrical work required. The unit uses 48 VDC power over CAT-5 cable and weighs less than 26 pounds, requiring no additional structural support in most installations. A surface-mount option is available for finished ceilings.

IAQP Reduces HVAC Costs and smartIAQ GridSet Enables It

The Indoor Air Quality Procedure is a performance-based compliance pathway in ASHRAE 62.1 that allows buildings to reduce mechanical outdoor air requirements. Where the traditional Ventilation Rate Procedure (VRP) sets outdoor air based on peak occupancy, building type, and space area, IAQP lets validated active air cleaning substitute for a portion of that outdoor air. That substitution is where the HVAC equipment right-sizing and energy savings come from.

Buildings pursuing IAQP typically see outdoor air reductions of 25–70% compared to VRP, depending on space type, occupancy density, and climate zone.

 

 

 

With in-room air cleaning and closed-loop monitoring, smartIAQ GridSet makes IAQP work at the zone level. Integrated solid-state sensors measure TVOCs, CO2, formaldehyde, and particulate concentrations. The unit adjusts cleaning output based on actual conditions and logs performance data to document that IAQP targets are being maintained.

For the full compliance methodology, how smartIAQ achieves IAQP compliance and how the IAQP works in ASHRAE 62.1 are both available as detailed technical references.

Where It Works: Classrooms, Offices, and Single-Zone Spaces

K-12 Classrooms

smartIAQ GridSet delivers 150 CFM of clean air for classrooms up to 1,500 square feet with ceilings up to 10 feet. Its NC-25 sound rating supports quiet learning environments, while installation requires no disruption to existing ceilings or mechanical systems.

For IAQP projects, documented outdoor air reductions of 65–70% can also reduce DOAS equipment costs and help offset deployment costs.

Commercial Offices and Conference Rooms

In buildings with conference rooms, HVAC systems are sized for the room’s peak occupancy, meaning that equipment decisions often affect the entire floor. GridSet enables in-room IAQP compliance at the zone level, so the central HVAC system doesn’t have to be sized around one room’s maximum capacity.

For open-plan offices, smartIAQ GridSet can be deployed to supplement a centralized smartIAQ configuration in spaces where targeted in-room air cleaning is needed.

Banks, Retail, and Single-Zone Commercial Spaces

In banks, branch offices, and retail spaces with standard drop-ceiling construction, smartIAQ GridSet provides IAQP-compliant air cleaning without the mechanical complexity of a centralized system. Coverage up to 1,500 square feet per unit and a 2-year filter life keep ongoing operational overhead low.

Frequently Asked Questions

Does installation require removing ceiling tiles or modifying ductwork?

smartIAQ GridSet doesn’t require ceiling tile removal or ductwork modifications. It lays directly into a standard ceiling grid and runs on 48 VDC low-voltage power delivered over CAT-5 cable. For finished ceilings without a T-bar grid, a surface-mount option is available. Most installations complete without disrupting the ceiling or the HVAC system.

What room size is smartIAQ GridSet designed for?

smartIAQ GridSet covers up to 1,500 square feet per unit at ceiling heights up to 10 feet, sized for standard classroom occupancy. For spaces above 1,500 square feet or with higher occupancy density, multiple units can be deployed. The smartIAQ Project Builder calculates the right number of units for a specific space based on occupancy, square footage, and IAQP design targets.

How does smartIAQ GridSet verify IAQP compliance?

smartIAQ GridSet uses integrated solid-state sensors to monitor TVOCs, CO2, formaldehyde, NOx, and particulate concentrations in real time. The Pro unit adjusts cleaning output based on actual conditions and logs performance data continuously.

That data record documents that IAQP contaminant targets are being maintained over time, which is what the ASHRAE 62.1 IAQP compliance framework requires. For the full technical methodology, see how smartIAQ achieves IAQP compliance.

 

Is smartIAQ GridSet the same as NPBI?

No. smartIAQ GridSet is GPS Air’s IAQP-enabling air cleaning platform for single-zone spaces. It delivers IAQP compliance through closed-loop monitoring and filtration tested to ASHRAE 52.2 and 145.2 standards.

GPS Air’s NPBI® soft ionization technology is a separate technology focused on general air quality, odor control, and particle agglomeration. NPBI is included on the unit for additional efficacy against particles and some airborne pathogens.
