Case Study

Taking the LEED at 320 Park Avenue

We’ve helped Mutual of America put 320 Park Avenue on the path to LEED-EB certification (Leadership in Energy and Environmental Design - Existing Buildings)—becoming one of the first office towers in Manhattan to seek LEED EB status. Along the way, we’ve earned five Energy Star Building designations, two BOMA Pinnacle awards and attained full tenant occupancy of the property.  

The first major initiative was a complete building redevelopment including new infrastructure, building systems, common areas and building exterior. Then we were hired to manage and lease the building. Capitalizing on the redevelopment, we preleased 437,000 s.f.—approximately 60% of the building—at the highest rates in the Plaza District sub-market. The building opened 65% leased, and was 97% occupied within 15 months.

In our ongoing efforts to improve energy efficiency, we implemented a comprehensive energy management program in 2002. This program resulted in cost savings of $327,000 per year.

320 Park Avenue has received the Energy Star Building designation by the U.S Department of Environmental Protection every year since our efficiency improvements. In fact, 320 Park Avenue was one of only five New York City buildings to achieve Energy Star designation in 2007 – making us a “star” with ownership.
