RETRO-COMMISSIONING STUDY

Want to save 5 to 25% on your energy bills with no/low cost efficiency measures, without installing new capital equipment? For many buildings, this is a very real opportunity through Retrocommissioning, which is a very sophisticated “tune up” of your building. Over and over again we find buildings that suffer from operational problems, where equipment control has drifted far from the original intent.



Through systematic analysis of building operations, analysis of trendlogs (data) from Building Automation Systems, and discussions with knowledgeable facilities staff, patterns emerge which point toward control and operational problems which waste tremendous amounts of energy, and which are often relatively easy to fix.

Some of the many problems in buildings we commonly find include:

• Scheduling problems
• Temperature and pressure setpoints incorrect
• Heating and cooling systems fighting each other and running
  simultaneously
• Improper amounts of outside air
• Broken economizer motors and dampers
• Miscalibrated sensors, especially global temperature and humidity sensors
• Leaking valves

B2Q can help you determine what problems exist and how to fix them, and we can help you apply for incentive money from the utilities to do so!
