Pneumatic vs DDC HVAC Energy Management Systems

Many older industrial buildings use pneumatic HVAC control systems. These manual controls have the benefit of long-lasting use – many buildings have pneumatic controls that have been in place for decades and continue to function. However, direct digital control or DDC are considered more energy efficient with many advantages not offered by pneumatic systems. If you manage or own a commercial building with pneumatic controls, it is important to know the benefits of DDC to determine if it is a better option for your building’s HVAC system.

Why Use DDC for Your HVAC Energy Management System?

If you have pneumatic controls, you may have wondered whether upgrading to DDC is worth the investment. If your energy costs are low and your industry does not require precise control over temperatures, pneumatic may work adequately. However, if you want to lower energy costs and improve your control options over your energy management, DDC can be worth the investment. Some benefits include:

  • Higher accuracy and precision with climate control
  • Improve energy efficiency with easier management
  • Advanced reporting systems
  • Easier adaption to automation systems
  • Wireless and remote control options

The drawbacks to a DDC over pneumatic energy management system are related to maintenance and longevity. In some cases, digital controls may need repairs or replacement more frequently than the more basic manual controls used in pneumatic. However, the savings in energy costs can more than make up for the difference and many DDC systems can still last for decades.

For building managers considering upgrading to a DDC system from pneumatic, talk to a expert. Consult an industrial HVAC installer that offers both systems to determine whether a retrofit to a new system is a wise investment for your building.
