Carpenter's Hall Rare Document Library Philadelphia, Pennsylvania
The Rare Book Library is located on the second floor of Carpenter’s Hall in Independence National Park.
Analyzed the existing facility for the necessary upgrades needed to store their rare books and manuscripts while maintaining the historic architectural character of the space.
Installed insulation and vapor barriers behind all the document cases to block out exterior conditions; removed the glass doors to provide ventilation; and operated the air conditioning system on a full-time basis to maintain uniform space conditions.
An improved HVAC control system was installed which included temperature and humidity sensing devices along with alarms to warn of environmental conditions beyond the desired operating profile.
