Siemens Introduces Demand Flow™

Siemens Industry, Inc., today introduced Demand FlowTM technology from its Building Technologies Division. Demand Flow is a proven Siemens patent-pending technology that optimizes central chilled water systems to reduce the plant’s total energy consumption by 20%-50%.

“We are excited to introduce Siemens Demand Flow chiller plant optimization solution and plan to make it widely available to our customers in both the existing buildings and new construction markets. Through a growing number of successful installations across the U.S., we’ve seen Demand Flow consistently and significantly improve chilled water plant operations. Demand Flow has reduced our customers’ total plant energy consumption in markets including healthcare, hospitality, data centers, high-rise commercial office buildings, higher education, manufacturing and pharmaceuticals,” says Andreas Schierenbeck, president of the Building Technologies Division of Siemens Industry, Inc.

Demand Flow offers facility owners and builders a holistic approach to optimizing the entire chilled water system, including potential air-side savings. With Demand Flow, central chilled water plants can more accurately maintain optimal differential system pressure. Demand Flow optimization often increases the deliverable tonnage of the chilled water plant and simplifies operations, without sacrificing occupant comfort in favor of energy savings. The energy savings from the annual kilowatt hour reductions can not only significantly reduce building carbon footprints but also help to achieve LEED credits when pursing sustainability goals.

Demand Flow is compatible with any building automation system and ready to optimize the entire chilled water system. Similarly, Demand Flow optimization can be implemented regardless of chiller manufacturer and without voiding equipment warranties.To validate total plant energy savings, Siemens offers energy analysis services utilizing the company’s “Chalk Talk” analysis tools.
