Overview
The IRS Service Center, built in the 1970s, was struggling with failing infrastructure, high utility costs, and deferred maintenance. With operations spanning call centers, training rooms, offices, and a large data center, the challenge was modernizing systems while ensuring continuous service for 3,000 employees. CEG was selected to deliver a deep energy retrofit to extend asset life, reduce energy waste, and enhance performance.
Solutions
CEG implemented a campus-wide retrofit, including replacement of failed cooling towers, decommissioning of steam boilers, and installation of modular condensing hot water boilers. The project converted 247 constant volume reheat boxes to VAV boxes, installed VFDs on AHUs, and integrated a new open-source BAS platform. Lighting was fully upgraded with LEDs and advanced controls. Additional work included asbestos abatement, UPS upgrades in the data center and 44 server closets, and extensive deferred maintenance resolution — at no cost to the client, as it was supported by $2.6MM in secured utility incentives.
Results
The project now delivers $2.1MM in verified annual cost savings, reduces energy use by 63,680 MMBtu, and cuts water consumption by 3,726 kGal. Electricity usage fell 70%, natural gas dropped 54%, and water use declined 24%. By modernizing critical infrastructure, CEG improved occupant comfort, eliminated $30k/month in temporary cooling tower rentals, and ensured long-term resilience of the IRS’s essential operations.
