Carnegie Museum of Natural History

The 120-year-old Carnegie Museum of Natural History, a National Historic Landmark Building in the heart of Pittsburgh’s Oakland section, housed an outdated and inefficient chilled water system capable of failure at any time. CJL Engineering was hired to conduct a Heating/Cooling Plant Energy Master Plan to develop an approach for the upgrade of the Chilled Water System. CJL provided a replacement design for the two 39 year-old chillers using new energy efficient equipment, and later did the commissioning on this facility.

Energy Center Pittsburgh – Uptown
This new plant is designed to serve the chilled water, steam and emergency power requirements of UPMC Mercy Hospital. CJL Engineering’s design solutions included:

Chilled Water – 5500 tons operating capacity with another 2750 tons of stand-by capacity.

Steam – 100,000 LBS / HR operating capacity with another 50,000 lbs / HR of stand-by capacity. Steam pressure is at 150 PSIG

Emergency Generators – 5 MW operating capacity with another 2.5 MW of stand-by capacity.

Design of the chilled water lines sizes for 30-inch HDPE (high density polyethylene) to exiting plant and 24-inch HDPE after the split.

Experience with the Energy Center Pittsburgh – Uptown project includes underground vaults associated with the steam installation as well. Vaults included both precast and poured in place installations.

The Energy Center Pittsburgh – Uptown project was a design-build effort with collaboration coordination and review with all stakeholders. Piping and conduit placement review and coordination continued throughout construction to assure that design objectives were met while avoiding underground obstacles, including those which had not been detected by earlier discovery methods. This effort served the project very well, particularly at the massively congested crossings of Forbes and Fifth Avenues.
Culinary Institute of America

Culinary Institute of America

The world famous Culinary Institute of America contracted directly with CJL Engineering as the Prime Professional to evaluate and provide their school with a “long term” view of their facilities and to act as the owner’s representative to identify Energy Conservation Measures (ECM’s) and to develop an RFP for ESCO Contractors to bid. CJL Engineering provided energy modeling calculations and Return-On-Investment (ROI) data to help the owner decide on the most effective and efficient path to take to mitigate current and future energy costs. Gross construction costs were estimated to be $8-$10 million.
Pittsburgh Energy Innovation Center

Pittsburgh Energy Innovation Center

Pittsburgh Gateways, a non-profit economic development support organization, purchased the historic Connelly Trade School and transformed it to The Pittsburgh Energy Innovation Center (EIC). A LEED Platinum building, and winner of the Green Development Award from NAOIP Pittsburgh in 2018, EIC’s cutting-edge training, education, and research center supports the new green economy in Western Pennsylvania, and showcases the new and evolving green building technologies and provides start-up facilities for emerging green business ventures. CJL designed a high-performance envelop with improved insulation, high performance glazing and sawtooth clerestories, daylighting, geothermal heating/cooling, EcoClean boilers with recycled plastic pellet fuel; Microturbine Combined Heat and Power generators, using biofuels for off-grid peak demand shaving,
Cambria County War Memorial Arena

Cambria County War Memorial Arena

The Cambria County War Memorial Arena is a 4,000-seat multi-purpose sports and exhibition facility. In a recent expansion and renovation, the arena gained central air-conditioning, new seating, improved public access, and ADA Compliance.

The new chilled water plant has two – 300-Ton chillers, and also serves the adjacent Frank J. Pasquerilla Conference Center. Central station air-handling units and a 4-pipe heating and cooling system serve the HVAC needs of the building. Rink refrigeration: low temperature ice building chiller, evaporative condenser, Ethylene Glycol pumps for rink piping, and redundant compressor/pumping arrangement.
