Roth Southeast Retro Commissioning

RETRO-COMMISSIONING

• Systematic, documented process for optimizing building performance
• Implement BAS controls never used or not working
• Examples of energy efficiency opportunities identified in RCx:

TYPICAL SYMPTOMS

• New building design that was cost centric, not energy centric design approach
• Old valves/actuators, pneumatic controls
• Poor building maintenance
• Limited building operator interaction with BAS

PROVEN RESULTS REDUCES OPERATING COSTS

• Save between 10%-20% of building energy costs
• A 2 Deg F supply air temperature error in a 20,000 cfm air handler costs an additional approximately $1,000 per year!
• Increase value of building
• Typical ROI is 10 to 16 months!
