Saint Elizabeths Hospital was founded in 1852 by an act of Congress as the Government Asylum for the Insane, the country’s first psychiatric hospital serving military personnel, as well as DC residents, on the principled approach of “moral treatment.” The East Campus initially served as the farm to support the West Campus and developed in the second half of the nineteenth century, as the center of scientific research for the hospital and provided expanding treatment services for patients.  Between the 1930s and 1940s the Continuing Treatment (CT) Campus was constructed as the first section of the hospital intended to house patients permanently.

The CT Campus project is the first project on the East campus to adaptively reuse and rehabilitate historic buildings.  The project is taking advantage of Federal Historic Tax Credits, as well as Low Income Housing Tax Credits.  The talk will discuss briefly the history of the campus and Master Planning efforts as well as the challenges of rehabilitating these historic buildings for new residential use.

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. Tom is an active advocate of sustainable designs in museums, libraries, archives, and historic sites. He is a LEED accredited professional, a Certified Energy Manager, and an APTI Recognized Professional. He has served on the Board of Directors for the APT NE Chapter since 2014, and is a frequent speaker in the preservation community on various HVAC sustainable design initiatives.  

Derek Trelstad joined Silman in 2006 and was promoted to Associate in 2007. His professional experience includes primarily historic preservation and renovation projects. Notable projects include restoration and alterations to accommodate new systems at St. Patrick’s Cathedral in New York, NY; ongoing work at the Cathedral Church of St. John the Divine in New York, NY; documentation of conditions and design of repairs at Cincinnati Museum Center in Cincinnati, OH; and existing conditions assessment and preservation plan for Montrose Placer Mining Company Hanging Flume in Uravan, CO. Derek has been active in numerous industry organizations. He is a former elected board member of the Association for Preservation Technology (APT) International and is currently a member of APTI’s Partnership & Outreach Committee. Derek was the co-founder and Chair/Co-Chair of the APT Preservation Engineering Technical Committee from 2003-2009. He has previously been honored with an APT Presidential Citation for outstanding contributions to the field of preservation technology and in 2018, APT inducted him in the inaugural class of APTI Recognized Professionals. Derek was a consultant to the ASCE Metropolitan Section on the ASCE Guide to Civil Engineering Projects in and around New York City, 2nd Edition, for which he edited the “Buildings” section.
