Improve Building Performance through Retro Commissioning

Commercial buildings throughout California and across the nation have a common problem: They seldom perform at design level. Optimum level provides the most efficient, comfortable and safe indoor environment for the occupants while balancing operation and maintenance costs for the owners.

Cooper Oates Air Conditioning Retro Commissioning (commissioning existing buildings) is a systematic process that solves this problem by allowing a building's HVAC system and integrated building controls to operate at peak performance. Retro Commissioning activities focus primarily on low-cost/no-cost optimization strategies that offer the greatest possibility for energy savings. Generally, the more complicated the mechanical system, the greater potential exists to discover opportunities that will improve building performance and save energy expense.

Retro Commissioning is a holistic approach to discovering the deficiencies that exist in a facility's HVAC and control system. This approach is extended out to the building envelope, which often is a significant contributor to comfort problems and energy waste. Envelope problems such as leaking windows, inadequate insulation in roof and wall connections, and unsealed penetrations in walls and slabs are typical and have a direct impact on the performance of HVAC systems.

Common Problems

In a study of 60 new buildings by Lawrence Berkeley National Laboratory [1], it was determined that:

  • 50% suffer control problems
  • 40% suffer HVAC problems
  • 15% have missing equipment
  • 25% have facility management systems/economizers/drives that don't function
  • 60% of insurance claims are related to HVAC problems
  • #1 source of complaints is related to HVAC problems

Retro Commissioning is a management tool that building owners and managers can implement to help solve the challenges of assuring a safe and comfortable indoor environment for the building occupants, with the least cost of operating and maintaining the facility.
