Retro-Commissioning Quality Assurance/Performance Testing
Retro-Commissioning can ensure that your heating, cooling, and other mechanical systems work efficiently together to save energy and reduce your operating costs.

• Retro-Commissioning is a quality control check, from project inception through the installation and operation of the energy efficient equipment.


• We supervise independent engineers who conduct onsite testing when systems are operational, and then work with the project engineers and contractors to resolve deficiencies.


• Retro-Commissioning ensures that the equipment installed operates as intended.


• Frequently, even with good project teams, the proper equipment gets installed and performs as its intended function of heating or cooling, but does not operate efficiently. The retro-commissioning process corrects these shortcomings and ensures that the equipment is running efficiently.
