Re-balanced air ventilation and heating systems to improve the office and reading room environmental conditions.
Reduced operating times of building services to suit the library occupancy profile.
Turned off lights centrally in low occupancy areas during the summer months.
By implementing these changes (at minimum costs) we were able to make energy savings of €20,000 over the course of a six month period. These savings were reinvested in an air barrier at the front entrance to the library, which reduces the amount of cold air entering the building in the winter and warm air in the summer.
We saved 155,000 KWH in 2017, which is equal to a 9% reduction in our energy use. This constitutes enough energy to power a light bulb for 1,770 years or travel around the world 24 times in an electric car!
