Forty years of evolution in HVAC controls have created highly sophisticated Building Automation Systems (BAS) which, when coupled with well designed mechanical systems, are capable of minimizing energy use while maximizing occupant comfort. However, their complexity creates many opportunities to improve energy efficiency through simple maintenance procedures and common program modifications. This webinar was presented by James Smith, Pulse Energy’s BAS Specialist, and included six simple tips that will save energy and increase the life of system components by helping your BAS run your building more efficiently. James has 18 years of experience as a factory trained controls technician working on installation and service of BAS systems for Siemens and Johnson Controls in office towers, universities, and hospitals.

3. 5 Energy Saving Tips for HVAC Controls
• Basic maintenance tips to
reduce energy use
– Mechanical inspection of
moving parts
– Software controls optimization

4. 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

5. 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

6. 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

7. Set AHU Supply Temperatures by Zone
Zone A
Boiler
Air Handling
Unit (AHU) Zone B
Chiller
Zone C
• 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

8. Set Boiler and Chiller Resets by Demand
Zone A
Boiler
Air Handling
Unit (AHU) Zone B
Chiller
Zone C
• Reset boiler and chiller temperatures based on AHU valve positions
• Protects against excessively hot or cold water, and machine cycling

9. Bonus Tip: Night Ventilation
• Save energy by pre-cooling
the building using outside air
at night
