Retro-Commissioning Services for Existing Buildings

Optimizing Performance, Efficiency, and Reliability in Existing Facilities

Retro-commissioning (RCx) is a systematic process for evaluating, optimizing, and improving the operation and maintenance of existing buildings. The goal of retro-commissioning is to ensure building systems operate as intended, improving energy efficiency, occupant comfort, and long-term performance.

E Cube provides retro-commissioning services for commercial, institutional, and large residential buildings across the United States and Europe, helping owners reduce operating costs and extend equipment life.

Benefits of Retro-Commissioning

Retro-commissioning delivers measurable benefits for building owners, operators, and occupants, including:

• Reduced operating and energy costs

• Improved equipment performance and reliability

• Fewer occupant comfort complaints

• More consistent temperature control and lighting

• Improved indoor air quality

• Reduced premature equipment failure

By addressing operational inefficiencies rather than capital-intensive replacements, retro-commissioning delivers high return on investment.
