Project Background A few years ago PNC Financial Services Group, Inc., based in Pittsburgh, became the first commercial establishment to embrace the sustainable building movement on a grand scale. They were the first to apply for LEED certification for a prototype design, and proceeded to convince the USGBC to pre-approve each building and simply audit individual branches (instead of requiring a full review process).
The branches were designed by architecture and interior design firm Gensler, while consultants CJL (an engineering firm) and Clemens Construction Company, or C3, assisted in seeing them completed. At various times PNC has planned building between 90 and 140 of these so-called "Green Branches." So far, as of October 2008, 55 have been constructed, opened, and have passed LEED certification, including 5 in the Cincinnati, Ohio area alone.
Strategies and Results Despite receiving no credits for sustainable sites given the location and type of project, PNC Bank was nonetheless able to use a variety of other strategies to achieve LEED Silver for this building, another of many in its "green" bank rollout. Like other PNC banks, this one uses a high-efficiency HVAC system and highly insulative glass to reduce energy use significantly (by 34% compared to federal standards), which contributes directly to seven points. It also is constructed from sustainable building products (such as local, recycled, and low-VOC materials), which contributes another nine points.
Other points of emphasis include focus on daylighting and views and water-efficiency--especially in regards to landscaping. (Bioswales surround the parking lot, and all vegetation is drought-resistant. This helps the bank save an estimated 4,000 gallons of water per year compared to a baseline building.) It is estimated that these steps, aside from being healthier, more environmentally friendly alternatives, save PNC approximately $100,000 over the life of the building.
Over half of all products are made from recycled materials. A large portion of products is also manufactured regionally. Further, between 75% and 95% of construction waste is recycled, an average of 150,000 pounds of material per branch.
