Principal Financial Group & M Moser Associates Earn LEED-CI at Vornado’s 888 Seventh Avenue

This 20,000-square-foot office near Columbus Circle has earned an unspecified level of LEED for Commercial Interiors certification.

The Principal Financial Group recently earned an unspecified level of LEED for Commercial Interiors (“LEED-CI”) certification for its corporate headquarters space on the 25th floor of 888 Seventh Avenue in Midtown. Designed by M Moser Associates, the 19,800-square-foot office includes extensive natural daylighting, low-flow water fixtures, and other energy-efficient systems. The space was designed to achieve a 15 percent reduction in energy consumption through occupancy sensors and programmable, efficient HVAC units.

The project team also included Synergy Construction, Inc. with LEED consultants OMNIBUILD, and only required seven months to complete. 888 Seventh Avenue, located on West 57th Street between Broadway and Seventh Avenue, includes 46 stories of office space, was built in 1969, and is owned by Vornado Realty Trust. Other major tenants include New Line Cinema and The Corcoran Group.
