Custom Packaged Rooftop Systems Contribute to LEED® Gold for Delta Dental of Michigan

Eden Prairie, MN (September 3, 2014) — A new case study released by CES Group describes how Mammoth custom packaged rooftop HVAC systems contributed to LEED Gold certification for Delta Dental of Michigan’s headquarters campus in Okemos, Michigan, a suburb of Lansing. 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."
