Result: Over $500,000 in savings over replacement
This 328,000 sq. ft. early 1900’s structure was converted to commercial use in 1998. The building is divided into north & south condenser water loops served by rooftop fluid coolers equipped with duplex pumps. Conditioned air is supplied by (2) water-cooled air-conditioning units centrally located on each floor. This work is being performed as a multi-year facility infrastructure energy efficiency & reliability improvements project. The project comprises
Repair & upgrade of the fluid coolers, duplex pump systems and air conditioning units. In addition to casing & structural repairs, the fluid coolers were upgraded with new fan assemblies, variable frequency drives, basin heaters, & water level controls. The condenser water system sequence of operation was optimized & retro-commissioned for variable speed pumping. Except for the retaining the OEM fan wheels all other mechanical, refrigeration & electrical components of the air conditioning units are being replaced. The new components for all units have been standardized to achieve improved energy efficiency & to reduce life cycle maintenance expenses. Integration with & commissioning of all systems via the building energy management system is being performed.
We take an engineering approach to evaluating and rebuilding equipment and mechanical systems. Our focus is on developing custom engineered solutions to maximize efficiency and value.
