LEED Project Overview:

Crescent Ridge Corporate Center I in Minnetonka, MN, achieved a first for Minnesota when it received LEED-EB Gold certification (Leadership in Energy and Environmental Design for Existing Buildings) for being the first multi-tenant building in the State to become LEED-EB certified.

The Crescent Ridge Corporate Center I Building, built in 1999, is a 265,489 square foot multi-tenant office building located in Minnetonka, MN, a suburb of the Twin Cities. The building was managed by Opus Northwest Management at the time of LEED-EB Gold certification. Building upgrades included the purchase and installation of alternative parking signs and bike racks, lighting modifications and a light meter purchase to decrease light pollution on-site, new humidity sensors, and implemented recommendations based on a full building IR Scan. The building was awarded LEED-EBv2.0 Gold Certification in February of 2009.

Results:

To minimize negative environmental effects, maximize the building’s operational performance and achieve long-term cost savings, sustainable practices drive Crescent Ridge’s building operations. These practices include:

• Green cleaning and sustainable purchasing programs in the building
• Construction waste reduction and recycling
• Alternative transportation and commuting programs
• Low mercury content per lumen hours light bulb purchases
• Reducing indoor water use by 33 percent over basic LEED requirements
• Achievement of an Energy Star rating of 91, which correlates to a 50 percent reduction in emissions compared to the average building
