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.
