Temple Adas Israel of Sag Harbor, Long Island’s oldest synagogue, was built in the late 1890’s by recently arriving Jewish immigrants who had settled on Long Island’s East End for factory work. The Temple combined the architectural form of a wooden Colonial church and an Eastern European synagogue, and services were first held in the building in 1898 for the celebration of Rosh Hashanah.
In the 1950-60’s a 2-story structure was added on the east side of the original building which has since deteriorated. The renovation project consisted of the demolition of the 1950-60’s 2-story addition and replacement with a new two-story and basement structure, with a total area of approximately 8,000 square feet. The new building addition houses a lobby, classrooms, a kitchen, bathrooms, support areas, and space for storage and mechanical equipment in the basement; and a new elevator connects all floors of the new addition.
All new engineering system infrastructure was added to the building, including a new energy efficient HVAC system with a focus on creating superior indoor air quality, new electrical and plumbing distribution systems, and new life safety systems were introduced into the historic Synagogue for the first time in its history making it a safer building as well. The engineering design was integrated into the architecture in a 3D building information model (BIM).
The new HVAC system consisted of DX split system air handling units provided with cooling by outdoor condensing units and heating from high efficiency hot water condensing boilers. The units contain high efficiency MERV and MERV 13 filters and they deliver fresh ventilation air to all spaces via an underfloor air distribution system. The original portion of the building was also provided with a new air handling system including an energy recovery ventilator to condition the incoming outdoor ventilation air required during times of peak occupancy with the waste heat of the exhaust air.
