Service overview

 

Retro-commissioning is a key step in improving a building’s energy efficiency.

 

Buildings consume more than 90% of the energy used in the United States,  and are a primary target for energy savings efforts

 

Utility companies, as part of Demand Side Management (DSM) programs, fund energy savings programs aimed at improving building efficiency and in some cases some government entities require to perform energy audits and retro-commissioning to ensure the correct equipment performance and installation. A good example is New York City Mayor's Office of Sustainability Local Law 87 (LL87: Energy Audits & Retro-commissioning) which requires buildings over 50,000 SF to undergo these periodic measures.

 

In order to qualify for such a refunds or comply with the requirements, the performance of the energy saving measure must be proven by a third party engineering firm to certify the performance to the utility funding the change.

 

“Retrocommissioning” does just that – it provides validation that an energy savings measure really does save energy.

 

 

 

 

 

 

Key Steps

 

 

EYP MCF review the existing systems, understand the operating parameters, measure the existing performance to establish a baseline, and design documentation (design intent, basis of design, commissioning book of record, and sequences of operation) for completeness.


EYP MCF will develop detailed written test procedures for guiding and documenting performance during functional testing to ensure that operations will not be jeopardized if it is a live facility.


EYP MCF will evaluate the documentation on record, produce any documentation that may be missing, and compile performance information for analysis and provide recommendations.


EYP MCF will observe the start-up of equipment and systems subject to the retro-commissioning process and perform field verification of the performance of the system.


This field verification may be in the form of direct measurements performed by EYP MCF, by observation of
measurements taken by others, or by data collection from calibrated system metering integral to the system being tested.


EYP MCF will perform commissioning of the equipment after start-up to verify full functionality and performance, taking further performance data readings as necessary.
 

This will include operating the system; testing in all normal modes; observing shutdown and restart; and abnormal, but predictable, operating modes (power failure, component failure, if applicable). In all instances, the commissioning will verify the predicted performance of the system as submitted and approved for purchase.
 

EYP MCF will make seasonal observations where required and review performance against the initial baseline measurements. This will provide validation for the Retro-Commissioning process and verification necessary to improve the energy efficiency of your facilities.
