Air-side optimization uses AI to continuously tune AHUs, VAVs, fan-coil units and ventilation from live comfort, occupancy and indoor-air-quality data – lowering HVAC energy use without sacrificing comfort.

Apps to optimize comfort & energy
Alto CERO Air-Side keeps zones comfortable without manual intervention. A comfort-optimization engine evaluates each zone every few minutes, computes thermal comfort from live temperature, humidity and CO₂ readings, and nudges fan-coil setpoints only when a zone drifts outside its band. When occupants tell the system a space feels too hot or too cold, it learns and adapts — shifting that zone's bias automatically over time.

Thermal Comfort
AI-powered Smart Building app that optimizes indoor comfort while reducing energy waste

Demand Ventilation Control
AI-driven ventilation control for energy savings and ASHRAE-compliant indoor air quality.

Occupancy Detection
Gives you real-time room occupancy visibility so you can automate HVAC and lighting based on actual use
Operators get a single air-side surface — a floor-plan view of every AHU, VAV, FCU and IAQ sensor, plus row and table views for fast scanning. Live analytics, automated reporting and fault detection turn raw HVAC telemetry into decisions, without manual spreadsheet work.

Auto Report (Air-side)
IPMVP-verified air-side savings reports with room-level IAQ insights.

Automatic Fault Detection & Diagnosis (AFDD)
Continuously monitors your building systems to catch issues early—so you reduce downtime, avoid expensive failures, and keep equipment running efficiently

IPMVP Data Analytics
Verify real energy savings with IPMVP-compliant baseline analytics – automatically eliminating weeks of manual spreadsheet analysis.
Scale air-side intelligence across your whole portfolio
Run more than one building? Alto Multi-Property rolls air-side performance up across every site — centralized monitoring, cross-property benchmarking and fault detection at portfolio scale, so a regional team can answer "is everything under control?" in seconds.
Explore how universities, offices and hotels use intelligent HVAC control to improve comfort, reduce energy consumption and automate daily operations.
Common questions about AI air-side HVAC optimization with Alto CERO.
What is AI air-side HVAC optimization?
It’s software that adjusts air-side equipment (AHUs, VAVs, fan coils, ventilation) automatically based on real-time comfort, occupancy and IAQ readings, instead of fixed schedules.
How much HVAC energy can Alto CERO Air-Side save?
Up to 30% HVAC energy, with up to 20% fewer comfort complaints and a payback period under 3 years.
Will optimization make the building less comfortable?
No — the engine computes thermal comfort (PMV) from live temperature, humidity and CO₂, and only adjusts setpoints when a zone drifts outside its comfort band; it learns from occupant feedback over time.
Does it work with split-type and VRF systems?
Yes — Alto CERO Air-Side supports split-type and VRF equipment.
How are the savings verified?
Through IPMVP-verified air-side reporting with room-level IAQ insights.
