Clean Indoor Air at Zero Incremental Cost
A smarter HVAC design strategy for new buildings.
Clean indoor air does not need to come at a premium.When AtmosAir Bipolar Ionization is integrated at the HVAC design stage, new buildings can improve indoor air quality, reduce energy consumption, and optimise HVAC capital costs - often achieving zero or near-zero incremental cost for air purification.
This is not an add-on.
It is a design optimisation strategy, enabled by ASHRAE 62.1.
Energy and IAQ Performance in GCC Buildings
When AtmosAir Bipolar Ionization (BPI) is integrated at the HVAC design stage, buildings can:
-
Improve indoor air quality
-
Reduce cooling and ventilation energy
-
Optimise HVAC system sizing and capital cost
In many projects, this approach to HVAC air purification delivers zero or near-zero incremental cost.
HVAC Design Challenges in High-Performance Buildings
Why green buildings often fail at the business-case stage
Despite strong sustainability ambitions, many projects struggle to justify IAQ and wellness strategies because:
-
HVAC capital cost is perceived as too high
-
Ventilation requirements drive oversized mechanical systems
-
IAQ is treated as a discretionary “upgrade,” not core infrastructure
As a result, indoor air quality is frequently value-engineered out — even though it directly impacts:
-
Health and absenteeism
-
Energy consumption
-
Long-term operating cost
-
Asset value and tenant satisfaction

Using ASHRAE 62.1 IAQP for Ventilation Compliance
A performance-based approach using ASHRAE 62.1 (IAQP)
ASHRAE 62.1 provides two compliance pathways for ventilation design:
1) Ventilation Rate Procedure (VRP)
A prescriptive method based on:
-
Floor area
-
Occupancy
-
Space type
This approach typically results in high outside air volumes, increased cooling load, and larger HVAC systems.
2) Indoor Air Quality Procedure (IAQP)
A performance-based method that allows compliance through:
-
Measured contaminant control
-
Proven air cleaning technologies
-
Continuous IAQ management
Rather than relying solely on dilution via outside air, IAQP enables smarter, responsive ventilation strategies.
ASHRAE 62.1-2025 increasingly encourages this approach.

The AtmosAir Solution
Bipolar Ionization for Large-Scale HVAC Systems
When AtmosAir Bipolar Ionization is integrated into HVAC design:
-
Airborne pathogens, VOCs, and fine particulates are continuously neutralised
-
Clean air is delivered throughout the entire occupied space
-
Dependence on high volumes of outside air is reduced
Typical outcome:
➡ Up to ~50% reduction in outside air requirements (project-specific and modelled during design).
The Financial Advantage
How Cleaner Air Reduces HVAC Capital Cost:
Reduced ventilation demand allows systems to be right-sized, resulting in:
-
Smaller chillers
-
Smaller air handling units
-
Reduced ductwork
-
Smaller plant rooms
In many projects, these HVAC savings fully offset the cost of AtmosAir, delivering clean air with no additional capital cost at the design stage.
Measurable Results
Typical outcomes for new buildings
Projects designed with AtmosAir and IAQP commonly achieve:
-
~12% reduction in total building energy use
-
Lower operating costs from day one
-
Healthier occupants, improved productivity, reduced absenteeism
-
Simplified pathways to LEED, WELL, and FitWel certification
(All outcomes are project-specific and can be modelled during design.)

Designed for GCC Conditions
Built for hot, dusty, high-occupancy environments
In the GCC:
-
Cooling dominates energy consumption
-
Ventilation is expensive
-
Dust, heat, and occupancy amplify IAQ risks
AtmosAir systems are engineered for large-scale buildings operating in extreme climates, making them particularly effective across the GCC and wider MENA region.
Proven & Trusted
Risk mitigation, not experimentation
-
Established for over 20 years
-
Independently tested and validated
-
Installed globally across hospitals, airports, offices, education, and hospitality
-
No ozone, no chemicals, low energy consumption
This is proven infrastructure - not emerging technology.
The Bottom Line
This is not an IAQ upgrade.
It is a design optimisation strategy.
Cleaner air. Lower energy. No extra cost.
