Library Preservation goes Green

Our March 2009 guest at the Library Green Team was Tara Kennedy, Preservation Field Services Librarian. Tara is tracking temperature and humidity conditions in collection areas throughout the library system. The systematic collection of data will help the preservation team identify opportunities for energy conservation that will not compromise the collections.

One experiment is already up and running in Sterling. The Sterling stack tower has six powerful HVAC units running simultaneously. Tara is using environmental monitoring to assess the impact of powering down one of the units periodically (some of the results are shown in the graph below).

The hope is that facilities can cycle through the HVAC units, reducing the total energy usage for conditioning the stacks. The experiment is ongoing and we look forward to hearing more as it progresses.

Many thanks to Tara for updating us on energy conservation efforts in the Preservation department!
