ENERGY SERVICES

• 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).

DESIGN SERVICES

• 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
