Switching tracks: Adaptive reuse at the Farley building

Original publication by Urban Green Council • October 23, 2019

At the heart of the project is the Moynihan Train Hall, a new train station which will service Amtrak and the Long Island Rail Road, decreasing the strain on Penn Station. The project will also add restaurants and retail spaces in the building for a more pleasant commuting experience. After the renovations, the post office will retain 270,000 square feet, 26 different carrier routes and the historic postal lobby. 

The renovation will also add 740,000 square feet of modern office space designed to encourage creativity and community within the workplace. The building is one of the largest in Manhattan, taking up two city blocks between 8th and 9th Avenue. The resulting horizontal floor plan creates nodes and intersections that will bring people together at the heart of the space.

The Farley Post Office’s status as a national landmark on the National Register of Historic Places created some constraints in the renovation, and designers avoided making any major changes to the underlying architecture. For instance, the planned green roof is limited to a small portion of the total roof because the refinished copper roof is historic. However, the renovation will make a few major changes, including the addition of a stunning 92-foot high skylight held up by the building’s original steel trusses.

The large building will use a combination of existing and new heating systems, Reagan explained to the curious members of the tour. The property is served by district steam, which will be supplemented by natural gas to provide heat and hot water. A wide variety of classic steam radiators will stay in place to keep the office perimeters warm, while the main train hall will also have hydronic radiant floor heating. That floor was still under construction, and tour members were able to see a rainbow-colored layout indicating the planned piping runs that will carry water to heat the space. And to reduce heat loss throughout the building, 2,000 old single-pane windows are being replaced with more efficient ones. 

After years of work, the major construction hurdles have been managed and operational systems such as escalators, lighting and air-handlers are ready to be tested. Within the next three months, the project developers will finish the heavier construction work and start preparing the building for interior finishes and system commissioning. And next winter, 118 years after it first opened, the Farley Building will once again open its doors to the public, welcoming thousands of train passengers, shoppers and office workers.
