Mammoth custom packaged rooftop HVAC systems contributed to LEED Gold certification for Delta Dental of Michigan’s headquarters campus in Okemos, Michigan.
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 helped the project earn the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) Gold certification.
The Mammoth systems contributed one point to outdoor air delivery monitoring (EQc1), which supports overall building energy efficiency.
They contributed three points to EAc1, Optimize Energy Performance, which reduces the operational costs when compared to standard HVAC systems.
The performance when compared to ASHRAE 90.1 Appendix G baseline was able to provide an energy cost savings of 14.7 percent, says, Scott Kemp, P.E., mechanical engineer, Albert Kahn Associates.
Additional LEED program credits were given on the basis of a number of sustainable design features at the Delta Dental campus.
Installation advantages included single sourcing, keeping most of the HVAC equipment out of the buildings and on the roof.
To save time and improve quality, advantage of the factory labor over a field-built installation was taken. Sole-source responsibility for the major equipment and for the mechanical room installation was also an advantage, added, Kemp.
