In Montana’s historic downtown Missoula, a Stockman Bank branch has recently earned LEED v4 Core and Shell Platinum certification — the second building in the U.S and the fifth worldwide to receive such accreditation. Designed by Billings-based architecture firm Cushing Terrell, Stockman Bank’s Missoula location boasts energy-efficient and energy-saving systems throughout, from high-performance glass and solar arrays to an innovative on-site rainwater system that provides 100% of average annual water use for toilet and urinal flushing. The six-story bank uses 75% less energy and 69% less water than a comparable office building.
Certified LEED v4 Platinum in September 2019, Stockman Bank’s downtown Missoula branch spans 67,753 square feet across six floors, two of which are used as parking with space for 137 vehicles, covered bicycle parking and electric vehicle charging systems. The top three building levels include outdoor terraces, while the sixth-floor rooftop level features a lush garden space that can be used for meetings, entertaining and community activities. The roof level overlooks panoramic views of Missoula and the surrounding valleys and is also topped with a 48.75 KW photovoltaic array with 150 solar panels that provide 11% of the building’s energy.
Despite the building’s inclusion of high-tech, energy-saving technology, the bank’s appearance is firmly rooted in the local vernacular respectful of its historic district location. The masonry exterior uses brick and quarried granite from South Dakota as well as cast stone detailing and a high-performance glass curtain wall that floods the interior with natural light. Approximately 70% of recycled material was used in the steel frame construction.
In addition to rainwater harvesting and solar panels, the bank includes an open-loop ground source heat pump system and chilled beams as well as energy-efficient elevators with regenerative braking to recoup electricity in descent.
