Komatsu Mining Corp. South Harbor office headquarters features Rockfon acoustic stone wool ceiling systems
Posted on September 26th, 2023 by Heather West
Komatsu Mining Corp., one of the world’s largest manufacturer of construction and mining equipment, recently opened its new South Harbor headquarters in Milwaukee, Wisconsin. Reflecting Komatsu's focus on sustainability and its company-wide goal for carbon-neutrality, the South Harbor office building is the only LEED®v4 Building Design and Construction (BD+C) New Construction (NC) Gold project in the City of Milwaukee and is the highest-rated LEED v4 BD+C in the State of Wisconsin. Komatsu’s new facility also is the largest urban manufacturing project of its kind in the country. Helping meet the project’s sustainability, performance and aesthetic requirements, Eppstein Uhen Architects (EUA) specified five types of Rockfon acoustic stone wool ceiling panels.
The company’s history in Milwaukee dates back to the origin of the P&H brand in 1884. The new facility is the largest urban manufacturing project of its kind in the country. It was designed and built to enhance Komatsu’s goal of “creating value together” by leveraging technology and open spaces, providing a globally connected meeting place for both company and community, and emphasizing sustainability.
“Our South Harbor campus and its many sustainability features are part of our global commitment to achieving carbon neutrality by 2050 and sustainable growth as a company," said Hiroyuki Ogawa, Komatsu's president and CEO. "This is an important goal for Komatsu along with society, as we all work to do our part to address global warming. Through this campus, we hope to contribute to the Milwaukee community by implementing our growth strategy.”
Along with EAU, other project team members on Komatsu’s headquarters included engineering firm GRAEF, LEED consultant Sustainable Building Solutions, Hunzinger Construction Company, and ceiling installing contractor Performance Contracting Inc. (PCI).
PCI installed Rockfon’s products in distinctive modular patterns using direct mount, standard and custom-sized lay-in tiles as well as concrete-colored panels with finished-to-match perimeter trim. Each ceiling product selection was acoustically optimized to meet the room’s functionality and sound absorption needs.
“The new campus provides us opportunity for advancement in state-of-the-art facilities that expand our capabilities on a global scale," said Jeff Dawes, president and CEO of Milwaukee-based Komatsu Mining Corp. "Our new facilities [are] designed to enhance safety, efficiency and environmental sustainability – all top priorities of Komatsu worldwide, allowing us to better serve our customers and deliver innovative solutions."
Delivering a 0.95 NRC, Rockfon® Color-all™ Concrete ceiling panels were installed on the first floor showcasing harbor views, and offering best-level sound absorption and a differentiating appearance. Several conference rooms’ feature Rockfon’s white ceiling tiles installed in a brickwork pattern for visual contrast to the symmetrical grid pattern used throughout the office areas.
The Rockfon stone wool ceiling products installed on Komatsu’s office building help in creating sustainable buildings. Made from a naturally fire-safe and durable material with no added flame retardants or biocides, stone wool resists moisture, humidity, aging, mold, bacteria and mildew. Further enhancing occupant well-being, Rockfon’s entire portfolio of stone wool ceiling products has been UL® Environment’s GreenGuard® Gold Certified for low-emitting products.
With sustainability and energy conservation as a key driver for Komatsu’s project, EUA partnered with GRAEF to design a facility expected to use 75 percent less electricity and 80 percent less water than the company’s former headquarters. Helping accomplish this, Rockfon’s white ceiling panels have a high reflectance to maximize natural and energy-efficient electric lighting. Up to 86 percent of light is reflected off the ceiling panel’s surface and produces diffused illumination that provides less glare for more comfortable, productive work.
Komatsu’s South Harbor office building utilizes other sustainable strategies including rainwater collection, a green roof system and ice storage for off-peak colling. The entire campus utilizes extensive photovoltaic, wind turbines, closed-loop heat-treat system and other innovative sustainable solutions.
Opened in June 2022, pre-construction work on the former superfund site began in 2019. Hunzinger began construction on site in the autumn of 2020 and worked closely with PCI to coordinate installation of Rockfon’s numerous interior ceiling systems.
Komatsu South Harbor office headquarters’ successful design and construction has been honored with:
• the 2023 Mayor’s Design Award
• the Wisconsin Commercial Real Estate Women Network (WCREW) 2023 Project of the Year
• the American Society of Interior Design’s Wisconsin Chapter (ASID-WI) 2022 Design Excellence Gold Award for Office/Corporate 50,000 square feet and over
• The Milwaukee Business Journal 2022 Best New Development Office award
• The Daily Reporter, a construction industry publication, 2021 Top Projects award and the Best in Show award
