Ornamental Copper Cornice Restoration at Trinity Centre in Lower Manhattan

Please allow APTNE to direct your attention skyward for an up-close perspective of this highly decorative copper cornice restoration! Built in 1905 and 1907 adjacent to Trinity Church, the Trinity Centre buildings were designed by Francis H. Kimball and are early examples of gothic inspired skyscrapers that defined the rapidly changing skyline in Lower Manhattan. This presentation will take us 18 stories up and discuss the challenges of restoring over 800 lineal feet of ornamental copper cornice on these early 20th century NYC landmarked commercial office buildings.

Virtual Meeting
Going Deep: Geo-thermal System Integration at St. Patrick's Cathedral, NYC

Please join us for a special discussion about the recent work at St. Patrick’s Cathedral involving everything just beneath the surface. The use of renewable energy sources and the preservation of our most iconic structures are two themes that have been rapidly converging over the last two decades. The back of house rooms that serve the picturesque, public spaces are often the most challenging and most rewarding areas for a preservation professional to approach. The Cathedral underwent a comprehensive restoration project that was completed in 2017. One aspect of the scope of work included upgrading all of the steam radiators and the 1960’s era HVAC system to a modern system using sustainable energy. A water-to-water geo-exchange system was installed that includes ten wells and a water-source heat recovery chiller connected to new air handlers and fan coil units. The modernization of the building systems was one challenge while the other was ensuring it would all fit within the tight existing footprint in mid-town Manhattan.

Presenters: Tom Newbold, Principal and Mechanical Engineer, from Landmark Facilities Group, and Derek Trelstad, Associate and Structural Engineer, from Silman will discuss the challenges and rewards of modernizing this 140+ year old National Historical Landmark. 

Tom Newbold holds a Bachelor of Science Degree in Mechanical Engineering and a Master’s of Business Administration. Tom is a licensed Professional Engineer in Mechanical Engineering in numerous states, and his work has focused on unique engineered systems in buildings for over twenty years. Tom has been involved in the study and design of special climate control systems throughout the United States and has a special expertise in the design of geo-exchange heat pump systems for unique applications such as historic house museums, libraries and archives. He is certified by the Association of Energy Engineers to be a Certified Geo-exchange Designer. Geo-exchange projects include Kenmore Plantation in Fredericksburg VA, Birdcraft Museum in Fairfield, CT, The Edith Wharton Estate in Lee MA, and the Frank Lloyd Wright Darwin Martin Estate in Buffalo NY.
