To further promote energy conservation and to raise the awareness of colleagues on environmental protection, the Observatory has decided to hold a departmental lights-off day every month with effect from September 2010. During the lights-off day, the Observatory will turn off some less essential lighting in the Headquarters for one hour.
The first Hong Kong Observatory Lights-off Day was launched on 3 September 2010. The Observatory will continue to hold lights-off day to support the promotion of energy conservation.
