1 Penn Plaza

One Penn Plaza stands out in the New York City skyline thanks to its signature red “1.”

The 57-story building contains over 2.7 million square feet and offers dramatic views of the entire city in its location close to Pennsylvania Station, Madison Square Garden, and Macy’s Herald Square.

We have worked on many projects in the building and tenant spaces for this Vornado property. As the portfolio engineer for the building owner, we provided design of much of the infrastructure upgrades, particularly those related to improving energy performance. We also provided oversight of the installation of a 6.2 MW CHP plant, the largest in a commercial building in NYC. Our work included an ASHRAE Level II Energy Audit, as well as all MEP-related LEED documentation services for a LEED for Existing Buildings Version 2008 application.
