June 29, 2011 / William Thomson, Green Homes Expert

A 522,000-square foot office building that used to be the headquarters for the Federal Reserve Bank of Minneapolis has become the first such facility in the region to achieve USGBC’s highest certification.

15-story Office Building in Minneapolis First to Bag LEED Platinum

Marquette Plaza, a 15-story multi-tenant office building, was constructed in 1972 in Minneapolis by architect Gunnar Birkerts initially to function as headquarters for the Federal Reserve Bank.

In 1997, the office building went under renovation and expansion, which were completed in 2002.

To date, the facility embraced sustainable upgrades under the stewardship of Base Management, with the collaboration of Sustology, a tenant and sustainability consultant for Marquette Plaza.

The effort consequently resulted in the office building to achieve LEED Platinum certification from the US Green Building Council, which is the first time that a facility from Minneapolis was awarded the highest certification from the green building council.

Currently, the office building is occupied by CenturyLink, Foley & Mansfield, Meet Minneapolis, Federal Government agencies and Xcel Energy.

Gene Rerat, president of Base Management, said: “We could not have earned this prestigious rating without our tenants’ commitment to sustainability. We had an overwhelming tenant participation in the certification efforts.”

The office building ranks as one of the only 47 multi-tenant office buildings worldwide to receive the highest certification under LEED.

The sustainable upgrade to the building will reduce energy costs, thus scaling back the tenants’ expenses, in addition to improved airflow and indoor air quality and better lighting.

Green features of the building include the use of renewable wind energy power to offset 100 percent of energy consumption that amounts to $1 million annually. Also, water conserving features of the office building cut down water consumption by 694,000 gallons.

The office building is also designed to save around 89 tons of waste that would otherwise add up to landfills every year.

Almost 1.5 acres of green roof covering constitute 46 percent of the total building area.
