Optimizing the performance & reliability of your air distribution system

What is Demand Flow for Variable Air Volume Systems?
Demand Flow for Variable Air Volume (VAV) systems is an end-to-end package solution that ensures you achieve maximum operational savings, improved building and occupant comfort, all with extended equipment time.

How does it work?
A traditional VAV system is inherently reactive to changing space conditions. With Demand Flow VAV, Siemens models the system to proactively control for maximum efficiency, without sacrificing comfort.

By implementing Demand Flow VAV, building owners can not only achieve their building performance and sustainability goals, they can also achieve:

Increased Energy Savings


  • Fan energy savings of 20% to 50% compared to using a fixed static pressure set point


Operational Improvements


  • Does not sacrifice comfort

  • Improves control

  • Extends equipment life

  • Reduces noise

  • Meets ASHRAE 90.1 requirements

  • Proactive control


Fast & Easy Implementation


  • Turnkey solution that’s easily implemented, minimizing overhead and generating a quick payback
