Naval Air Station Joint Reserve Base New Orleans (NAS JRB NOLA)

Scope of Services
Retro-Commissioning (RCx)

Naval Air Station Joint Reserve Base New Orleans (NAS JRB NOLA) provides training for active-duty and reserve components of all branches of the armed services. Retro-commissioning is required every four years at most federal facilities as specified in the 2007 Energy Independence and Security Act (EISA).

2RW Project Case Study Main Image

2RW provided retro-commissioning services to identify building system operational changes, repairs, and upgrades could help reduce energy use.

Services included:

  • On-site investigations of more than 330,000 SF across 12 buildings.
  • Testing and data-logging the performance of 13 chillers, 10 boilers, and more than 40 air handlers. Each building required a custom testing and trending strategy to accommodate differing systems, usage (offices, fitness centers, laboratories, recreational facilities, classrooms, and hangars), and amount of time the space was occupied during the day.

Challenges on this project included identifying ways to handle dehumidification in an extremely humid climate.


2RW’s energy engineers identified a number of energy savings opportunities, some of which included control modifications for sequences of operations and equipment scheduling. We recommended repairs and replacements throughout the 12 buildings to improve building efficiency and occupant comfort. NAS JRB NOLA implemented nearly all of the recommendations.

The success of this project was measured both in occupant comfort and energy savings.

  • After changes were implemented, 2RW conducted an on-site survey of building occupants. Results showed that comfort levels had been greatly enhanced.
  • Energy savings was projected to be 31%.
