equipment is at a premium. The total construction cost for
this project was $85.7M ($398/ft2 or $4290/m2), with $8.3M
($39/ft2 or $415/m2) dedicated to the HVAC and plumbing
cost. Energy modeling for the project was simulated for
LEED certiﬁcation to demonstrate that the building performs 44.6% (energy cost) better than a baseline building,
deﬁned using the Performance Rating Method in ANSI/
ASHRAE/IESNA Standard 90.1-2007, reducing signiﬁcantly
long-term operational costs. In addition, the geoexchange
ground loop, as previously mentioned, was "right-sized" to
handle the majority of the building's heating and cooling
load, and will last the life of the building without requiring replacement or any anticipated maintenance.

Environmental Impact
The multiple sustainable strategies involved with the
Helen Sommers project helped it achieve 83 points out
of a possible 100 points under LEED-NC v2009, which
qualiﬁes it for a Platinum Rating.
A signiﬁcant reduction in CO2 emissions has also been
achieved. Using the LEED v2009 EAp2 Minimum Energy
Credit and ENERGY STAR® Target Finder,
the project has reduced its carbon emissions by 71% over the typical ofﬁce building. The impact of that is equal to remov- https://bit.ly/2Z2fFn7
