DESCRIPTION
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.

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