“Sustology took Marquette Plaza from worst to first!”

Marquette Plaza

OPPORTUNITY

Marquette Plaza, an iconic high-rise office tower in downtown Minneapolis, has transitioned through multiple uses since its construction in 1973 as the Federal Reserve of Minneapolis. Designed by world-renowned architect Gunnar Birkets, the building had been highly praised as an engineering achievement at the time.  It was the first building to use catenary cables to support floors, much like a suspension bridge. Over the years, the building had been plagued by problems such as asbestos. Marquette Plaza’s negative reputation continued to haunt its buildings operations manager, Base Management, who approached Sustology for help.

SOLUTION

Sustology evaluated Marquette Plaza through US Green Building Council’s Leadership in Energy and Environmental Design (LEED) for Existing Buildings Operations and Maintenance (O+M) and determined that the building could achieve LEED Platinum certification with the right commitment to upgrades and changes in policies. Sustology led Marquette Plaza through LEED O+M certification in 2011.  This re-established its iconic status as it became the first downtown Minneapolis building, and one of only 88 of its kind in the U.S., to earn LEED Platinum certification.  Marquette Plaza made its mark as the first large multi-tenant building in Minnesota to receive Platinum certification, due to a rigorous series of efforts and implementations set forth by Sustology. The 22 building tenants included Xcel Energy, several Federal Government agencies, Foley & Mansfield, Meet Minneapolis, and CenturyLink. It is now home to the second largest green roof in Minneapolis, and 100% of the building’s $1 million annual energy use is offset by renewable energy.

The Bottom Line
Sustainability investments paid for themselves in two years, saving $250,000 annually in operating costs. LEED Platinum Certification continues to attract long-term tenants and increases the value of the property.
