Optimize Capital Investment
Lowering outdoor-air loads allows engineers to right-size HVAC equipment, ductwork, and energy-recovery systems. This helps control upfront equipment costs and preserves valuable building space.
Engineer Better Buildings with the Indoor Air Quality Procedure
Clean indoor air is more than a design requirement—it is a core business asset. WellAir helps engineers apply performance-based indoor air quality strategies to optimize ventilation and HVAC design.
By combining advanced air purification with smart modeling, our solutions reduce energy demand, improve indoor environments, and deliver measurable long-term value.
Clean Indoor Air Is a Business Asset
Traditional ventilation relies on high volumes of outdoor air to manage indoor contaminants. Conditioning that outside air increases mechanical loads, equipment costs, and energy use—without guaranteeing clean air.
The ASHRAE Standard 62.1 Solution:
The Indoor Air Quality Procedure (IAQP) offers a performance-based design pathway. Engineers evaluate indoor and outdoor contaminants to combine smart ventilation with validated air purification.
Key Owner Benefits:
- Lower Operating Costs: Reduce outdoor air conditioning loads.
- Smaller Equipment Footprints: Right-size mechanical equipment without sacrificing safety.
- Healthier Spaces: Ensure continuous air cleaning and stronger building performance.
Design for Better Air—and Better Business Outcomes
Reduce Operating Costs
Conditioning outside air demands significant energy. An IAQP strategy reduces heating, cooling, and dehumidification loads while maintaining target indoor air quality.
Expand Design Flexibility
IAQP opens up new pathways for space-constrained retrofits, high-occupancy spaces, and VRF systems—especially where conventional ventilation is impractical or cost-prohibitive.
Deliver Measurable Performance
WellAir combines air purification, sensing, monitoring, and engineering support. We help teams move beyond initial design intent to maintain real-time visibility into building performance.
VRP and IAQP: Two Paths to Acceptable IAQ
Ventilation Rate Procedure (VRP)
- Approach: Prescriptive rates based on floor area and room occupancy.
- Trade-off: Widely used, but introduces higher energy loads and ignores specific indoor contaminant levels.
Indoor Air Quality Procedure (IAQP)
- Approach: Performance-based modeling based on contaminant sources and air-cleaning performance.
- Outcome: Calculates the ideal mix of fresh outdoor air and purified recirculated air.
The IAQP does not replace ventilation—it allows engineers to pair air cleaning with reduced outdoor air for a more efficient design.

Top IAQP Opportunities
IAQP strategies deliver the highest value in high-occupancy spaces, constrained retrofits, and extreme climates:
- High-Occupancy Spaces: Schools, classrooms, lecture halls, auditoriums, fitness facilities, and assembly spaces.
- Constrained Facilities: Space-limited retrofits, adaptive reuse projects, and VRF or outdoor-air-limited systems.
- Challenging Environments: Hot, humid, cold, or wildfire-smoke-affected climates, and projects pursuing ESG or healthy-building certifications.
Each project should be evaluated individually based on occupancy, contaminants, system configuration, climate, applicable codes, and owner priorities.
