Mammoth’s Custom Packaged DX Systems Earn Project LEED Certification

The project included a 300,000 sq. ft. expansion and the construction of a new 100,000 sq. ft. building. Mammoth custom-packaged DX systems were selected, and ultimately helped the project earn the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) Gold certification for New Construction.

The Mammoth systems contributed one point to outdoor air delivery monitoring (EQc1), which supports occupant comfort and well-being, as well as overall building energy efficiency. They contributed three points to EAc1, Optimize Energy Performance, which reduces the buildings’ operational costs when compared to standard HVAC systems. “The efficiency of the Mammoth air conditioning systems contributed to the overall building performance which, when compared to ASHRAE 90.1 Appendix G baseline, was able to provide an energy cost savings of approximately 14.7 percent,” says Scott Kemp, P.E., mechanical engineer with Albert Kahn Associates. Additional LEED program credits were granted based on a number of sustainable design features at the Delta Dental campus.

Installation advantages to the owner included single sourcing and keeping most of the HVAC equipment out of the buildings and on the roof. “We wanted to take advantage of the factory labor over a field-built installation to save time and improve quality,” noted Kemp. “Sole-source responsibility for the major equipment and for the mechanical room installation was also an advantage.”

General Motors Corporation M5 Chiller Plant

GM Will Install Over 18,000 Tons of Chillers

General Motors Corporation recently selected Carrier to provide twelve (12) 1500 ton model 19XRV centrifugal chillers, to be installed in three (3) separate modular central utility chilled water plants, as manufactured by Epsilon Industries in Kingston Ontario.  These three (3) chilled water plants and over 18,000 tons of chillers will serve the body and assembly needs of the GM Fort Wayne IN, Flint MI and Arlington TX plants.

General Motors chose Carrier for many reasons; including the semi-hermetic (non-open) design of the compressor motor assemblies as well as refrigerant cooled VFD’s to avoid sensible heat gain to the central utility plant, and their extremely efficient 2-stage part-load and full load efficiency.

We need make special mention and thanks to Climate Technologies Corporation, the local representative for Epsilon Industries. These plants are works of art.
