5 Energy Saving Tips for HVAC Controls

• Basic maintenance tips to reduce energy use

– Mechanical inspection of moving parts

– Software controls optimization

Page 4: Energy tips for HVAC controls systems

Inspect Air Handling Unit (AHU) Valves

• Heating & cooling valves should be inspected annually

• The effect of a passing valve can be hidden by the response of the other valve

• Protects against simultaneous cooling & heating

Page 5: Energy tips for HVAC controls systems

Inspect Mixing Dampers

• Mixing dampers should be checked seasonally

• Protects against simultaneous cooling & heating as well as incorrect building pressure

• The effect of damper failure can be hidden by the response of the coil valves

Page 6: Energy tips for HVAC controls systems

Add Fresh Air Control

• Automatically calculate the fresh air requirements

• Protects against excess heating or cooling

• Can be hidden by the action of heating and cooling valves

Page 7: Energy tips for HVAC controls systems

Set AHU Supply Temperatures by Zone

• Calculate demand from zone devices to set the AHU temperature

• Eliminates over-cooling

• Effect of too much cooling can be hidden by re-heat valves

Set Boiler and Chiller Resets by Demand

• Reset boiler and chiller temperatures based on AHU valve positions

• Protects against excessively hot or cold water, and machine cycling
