Three-Acre Green Roof Helps Earn LEED Gold For Gateway Arch Museum

The new Visitor Center and Museum at Gateway Arch in St. Louis, MO is one of only 10 National Park Service sites to be awarded LEED certification.

Three-Acre Green Roof Helps Earn LEED Gold For Gateway Arch Museum

Located almost completely underground and featuring a 3.1-acre green roof, the newly renovated Visitor Center and Museum at the Gateway Arch in St. Louis, MO has been awarded LEED Gold. Thanks to the building’s sustainable site development, water savings, and building materials selection, the Visitor Center and Museum join the exclusive ranks of only 10 other LEED (Leadership in Energy and Environmental Design) certified sites in the National Park Service and 185 LEED projects in St. Louis.Gateway Arch National Park in St. Louis

Cooper Robertson and James Carpenter Design Associates, with Trivers Associates, designed the 150,000-square-foot expanded and renovated Visitor Center and Museum at the Gateway Arch. Ground breaking on the project took place in April 2015 and it opened to the public in July 2018.

“The National Park service has ambitious sustainability goals that the design team embraced enthusiastically,” said Scott Newman FAIA, Director, Cooper Robertson. “In addition to a 3.1-acre extensive green roof, the building features further sustainable and resilient design components such as LED lighting, high-efficiency HVAC systems, and close connections to local public transportation networks. These features bring a high level of efficiency that matches the National Park Service’s ambition. The LEED Gold certification recognizes that commitment and design innovation.” said, Scott Newman FAIA, Director, Cooper Robertson

Gateway Arch National Park in St. LouisFeatures of the Visitor Center and Museum at the Gateway Arch that contribute to the LEED Gold certification include:

  • 99% of the roof of the new Museum at the Gateway Arch is vegetated. This drastically reduces the “Heat Island Effect” and maximizes the amount of open park space. This results in an unimpeded view of the Gateway Arch and more room for visitors to roam and explore the grounds on foot.
  • More than 80% of the construction waste and demolition debris generated by the project has been diverted from landfills or incineration facilities.
  • Low flow water fixtures reduce the overall project’s potable water usage by more than 31% from the baseline.
  • Energy cost savings for the project is 24% below the baseline.
  • Materials used throughout the project were selected based on their recycled content, are regionally extracted and manufactured (within 500 miles), and wood products have met responsible forest management requirements.
  • Low emitting materials were selected to benefit the indoor air quality.
  • Throughout the project there are dedicated areas for the collection and storage of materials for recycling.
  • The project is closely connected to local public transportation systems including two Metrolink stops, Arch/Laclede’s Landing and 8th & Pine, that are within a half-mile walking distance and provide more than 450 combined stops per day.

While the LEED Gold recognition is for the Visitor Center and Museum at the Gateway Arch, additional measures across the national park grounds ensure the entire 91-acre Gateway Arch National Park is environmentally smart. Water cisterns collect or recycle storm water and guard the Mississippi River and reflecting ponds from run-off. The North Gateway replaced a parking garage and is now a “carbon sink” that drains emissions from the air. Tree soil, bioswale soil, and structural soils were custom mixed to ensure healthy plant growth.  Liquid Biological Amendment (compost tea) restores missing organisms and nutrients to the soil. Radishes were planted to naturally aerate the ground and as they decompose, enrich the soil.

“We are proud of the thoughtful planning and implementation of the sustainable initiatives that went into the renovation and construction of the new Visitor Center and Museum at the Gateway Arch,” said Mike Ward, Superintendent Gateway Arch National Park. “Reducing our environmental impact is a top priority across the National Park Service. The sustainability measures we instituted here meet that goal and they also create an enjoyable visitor experience across our beautiful park.”
