HVAC Repairs
The Library’s HVAC (Heating, Ventilation, Air Conditioning) system is undersized and has degraded substantially over time.
Engineers from OLA Consulting Engineers did an extensive study on the Library’s current system, which was installed in 2007. The geothermal well system cannot maintain a constant water temperature, especially during extreme air temperatures in the summers and winters. The well field capacity is undersized, and lacks water level controls and appropriate alarms. The building’s A/C units are undersized and have deteriorated, making it impossible for the Library to cool adequately during the summer months and warm during the winter.
Library patrons have expressed discomfort with the temperature during the summer and winter; 30% of complaints fielded by the Front Desk staff are temperature-related.
Building on the Best
For more than 130 years, the Ossining Public Library has established a legacy of service, enrichment, and inspiration to the greater Ossining community. Chartered as The Sing Sing Public Library in 1893, the library began as a collection of 700 books in the superintendent’s office before finding a permanent home on Croton Avenue in 1914.
This year, we’re looking to build on our legacy with a necessary and innovative renovation.
