Siemens Building Technologies – Demand Flow

“A clear benefit to users and the world”

Demand Flow is a unique, patented and proven energy- and operational-cost-savings application for water-cooled, central-chilled water plants. Designed for buildings with central chilled water plants in mind, this powerful solution has proven to reduce a chiller plant’s energy consumption by 20 to 50 percent.

“This is a clear benefit to users and the world. Well articulated benefits of a creative innovation that has had successful market penetration with confirmed results,” explained one judge.

A holistic optimization of the entire chilled water system — including Chillers, CHW Pumps, CW Pumps, CT Fans and AHU Fans — Demand Flow provides a savings of 1 million Kwh, which they claim is enough to surpass most short-term sustainability goals while drastically reducing operational expenses throughout the building’s lifecycle.

Siemens’ system solves the industry-wide shortcoming of “Low Delta-T Syndrome.” Demand Flow not only improves the efficiency of the chilled water system but also increases system deliverable tonnage, improving system redundancy. This increase in system deliverable tonnage means that a Demand Flow system can cool more effectively and do so with less operating equipment at any given time.
