Library Energy Conservation Benchmarks presents detailed data largely from academic and public libraries about their efforts to conserve energy and reduce their greenhouse gas imprint. The report covers a broad range of energy use and environmental issues including but not restricted to: architectural and structural changesto preserve energy, better use of insulation, current and planned use of alternative energy sources such as wind, solar and geothermal; management of library-operated vehicles; use of energy audits and energy-efficient computer workstation management, among other issues.
Some of the many conclusions from the report are that:
* 9.1% of the libraries in the sample use a wattage measuring device to routinely measure electricity use by appliances and close to 9% have conducted an electricity consumption audit within the past year to determine electricity use for different divisions, rooms or sections of the library.
* The average library in the sample experienced a 3.23% increase in their electricity bill within the past year. For college libraries this was much, much higher, a mean of 9% and a median of 8%.
* Most libraries in the sample used gas heat, with one spending $287,500. Mean spending by libraries that use gas heat was $44,280.
* 15.56% of the libraries in the sample plan to replace single panel with double panel windows within the next three years.
* 6.67% plan to introduce atriums or skylights into the library in the same period and for the same purposes.
* A third of the libraries in the sample plan to introduce sensors that detect motion and turn lights off and on when needed.
* More than 68% of the libraries in the sample have made efforts to replace lighting with higher efficiency light bulbs.
* Close to 9% of the libraries in the sample have installed sensors in vending machines so that they use energy only during hours of service.
* Only 2.27% of the libraries in the sample use solar or geothermal energy generated by the institution itself for heating. 4.44% use solar energy to augment their electricity supply. All users were larger libraries with budgets of greater than $500,000.
* 11.11% of the libraries in the sample plan to install solar energy generators within the next three ears; most with such plans were public libraries.
