Why Address HVAC Energy Consumption
in Commercial Buildings with Hydronic Systems
According to the U.S. Energy Information Administration, commercial buildings
consume about 40 percent of all energy worldwide, and HVAC systems account
for more than 40 percent of buildings’ energy usage. Hydronic flow optimization
is a prime way to reduce HVAC energy consumption, while increasing overall
building efficiency and operational performance.
How to Design Hydronic Systems for Energy Efficiency
Whether used separately or in combination, hydronic flow systems can be
optimized with Siemens Pressure Independent Control Valves, or PICVs, and
BT300 Variable Frequency Drives, or VFDs:
• PICVs combine the functions of a control valve, automatic pressure regulator,
and flow limiter ensuring the flow changes only when and where you want
it to change, as well as simplifying the basic hydronic system.
• VFDs reduce pump speed to optimize flow and lower energy consumption.
• Together they optimize hydronic flow, maximize energy savings and
provide comfort throughout the building.
