Reduce cooling waste while maintaining healthy indoor air quality.

The Demand Ventilation app is an AI Sustainability solution that delivers the right amount of fresh air—no more, no less—based on real-time occupancy and indoor conditions. Instead of running outdoor air dampers at fixed positions all day, the system continuously monitors CO₂ levels and humidity to optimize ventilation rates dynamically.

By reducing unnecessary outside air conditioning load, buildings can achieve 5–10% energy savings while automatically maintaining ASHRAE 62.1 compliance.

This is a core module within a Smart Building Solution and Energy Management System Thailand, helping hotels, offices, and mixed-use developments move closer to Net Zero Building Solution goals.

The system continuously measures:

• Indoor CO₂ concentration

• Indoor humidity levels

• Occupancy patterns

Using intelligent control logic, it:

• Adjusts outdoor air dampers dynamically

• Reduces fresh air during low occupancy

• Increases ventilation when CO₂ rises

• Prioritizes humidity control in tropical climates

The result: lower cooling load, better comfort, and verified ventilation compliance.

• 5–10% energy savings from reduced outside air conditioning load

• Automatic ASHRAE 62.1 ventilation compliance

• Improved humidity control in humid climates like Bangkok

• Supports ESG reporting and carbon reduction goals
