GSA Chicago ESPC Project UpdateMay 13, 2015

GSA Chicago ESPC Project

Greetings from the Chicago project team! Greg Deger and Erika Miller are on site to cover the 12 Energy Conservation Measure project which involves seven federal buildings in the Chicagoland area – all but one are located downtown Chicago. The list of ECMs are as follows:

ECM 1 Lighting Improvements in the 536 S. Clark Street Federal Building

ECM 2 Lighting Improvements in the 610 S. Canal Street US Custom House

ECM 4 Lighting Improvements in the 75th Street & Pulaski Federal Archives Building

ECM 6 Lighting Improvements in the Jackson Street Ralph H. Metcalfe Federal Building

ECM 7 Chiller Plant Improvements at the Chicago Federal Center Complex (Dearborn Everett M. Dirksen US Courthouse Building/Jackson Street John C. Kluczynski Federal Building/Dearborn U.S. Post Office Loop Station Building)

ECM 8 Boiler Plant Improvements also at the Chicago Federal Center Complex

ECM 8A Boiler Plant Demolition and PRV Stations also at the Chicago Federal Center Complex

ECM 9 Controls System Upgrades in the 536 Clark Street Federal Building

ECM 11 Controls System Upgrades (Glycol Loop) in the Dearborn Street Everett M. Dirksen US Courthouse Building

ECM 13 HVAC Upgrades in the Dearborn Street Everett M. Dirksen US Courthouse Building

ECM 14 Controls System Upgrades in the Jackson Street Ralph H. Metcalfe Federal Building

ECM 15 AHU Upgrades in the Dearborn Street Everett M. Dirksen US Courthouse Building

Lighting ECMs include upgrades to reduce the electrical intensity and maintenance burden of the buildings by retrofitting (or replacing in some cases) interior lighting with fluorescents and de-lamping fixtures with reflector kits. Also involved in these ECMs are replacing exit signs that are not already LED and installing battery backup for those not on emergency generator service. Buildings involved are the US Custom House (12 story office building, involving 1,724 fixtures), the 536 Clark Street Federal Building (10 story office building, involving 1,573 fixtures), the Ralph Metcalfe Federal Building (28 story office building, involving 7,529 fixtures total) and the Federal Archives Building (single story, 3 honeycomb shaped interlocking office buildings with 4 large warehouse areas and a receiving dock, involving 298 fixtures total).

Controls System ECMs include upgrades and retro-commissioning to remedy deficiencies, save energy, and improve operations by correcting deficiencies identified in retro-commissioning studies, implementing set point adjustments and new control strategies (including occupancy sensors), installing VFDs on chilled water pumps at the Metcalfe and 536 Clark buildings, and connecting walk-in coolers and freezers to the existing building glycol loop system at the Dirksen Federal Courthouse building.

Chiller Plant Improvement ECM includes a new 5,400 ton chiller plant serving the Federal Plaza and maintenance, repair and replacement services on existing equipment. Boiler Plant Improvement ECM includes replacement of existing plant at end of its useful life and relocate to make room for future construction, new 100,000 pph low-pressure steam boiler plant serving the Federal Plaza.

AHU Improvements ECM includes renovating to renew aging equipment, improve tenant comfort, and produce energy savings, upgrades to 22 AHUs in the Dirksen building and variable chilled water flow.

Challenges on the project include working with sensitive tenants such as the federal court system, risk mitigation therefore with noise/odor/disruptions of any kind, working with variable weather conditions to shut down existing systems for months at a time to install new boilers/chillers, lighting retrofit kits not fitting in ceiling spaces available without obstruction issues, addition of return grilles in the Metcalfe lighting project to compensate undersized return air flow in new lighting fixtures, and asbestos abatement areas found throughout CFC project buildings.

Project costs come to $63 million with project scheduled completion by March 2016, adding the ECM 8A work to follow commissioning and closeout and completion by December 2016.
