Pine Bluff Arsenal

Scope of Services
Detailed Energy Study (DES)
Mechanical, Electrical, Plumbing (MEP) Engineering

Under the oversight of the Army Corps of Engineers, 2RW completed a detailed energy study (DES) of Pine Bluff Arsenal with related engineering design services to support a guaranteed energy savings project. The arsenal was established in 1941 to produce and store armaments in support of US military and allied forces in combat zones worldwide.

2RW Project Case Study Main Image


  • Performed a DES of one million square feet at 130 separate facilities. The study focused on decommissioning fifty-year-old centralized steam generation plants and related distribution networks serving five production areas.
  • Conducted analysis using Trane TRACE™ 700 whole-building simulation software.
  • Created and calibrated baseline simulation using metered data following the Federal Energy Management Program’s M&V Guidelines.
  • Quantified anticipated energy savings by updating model with recommended energy conservation measures (ECMs).


  • Provided design services for the implementation of production-area ECMs that were identified in the DES.
  • Prepared construction documents for central steam system decommissioning, with replacement electric boilers in more than 50 facilities and four major process areas.
  • Designed chiller and pump replacements for cooling systems and electrical system upgrades.
  • Conducted site visits, prepared as-built drawings, and provided critical information for owner and construction personnel.

The estimated annual energy savings due to the DES and related services is $4.7 million.

ECMs Identified

  • Retro-commissioning
  • Disconnection of obsolete and inefficient loads and piping
  • Decentralization of inefficient steam plant
  • Installation of new chiller plants
  • Retrofit of five office facilities (including the historic Administration Building) with geothermal heat pumps
  • Addition of building automation and metering systems as the backbone of the first complete Energy Management and Control System
