FOI - EIR - Lighting at GLA [Mar 2021]

You requested:

Do you have any Filament Light-bulbs in buildings (offices etc.), if so are these scheduled to be upgraded, if so when? Also please provide number of filament bulbs.

Do you have a current count of how many LED bulbs you are using?

Do you have any Halogen Bulbs, if so are these scheduled to be upgraded, if so when? 

Also please provide number of Halogen bulbs. 

Can you provide me with your average yearly costs of replacing/upgrading bulbs and the 
price paid per bulb. 

Can you provide me with your energy usage from lighting council buildings broken down by each month from January - December 2020. (If this information is not available, total building energy consumption will suffice).

Do you have a policy for light bulb purchases currently in place?

What percentage of your lighting is using efficient LED Luminaries?

Please find below the information we hold within the scope of your request:

We do not have any Filament lamps onsite.

Currently we have upgraded 560 to LED Lamps.

We have approximately 3,265 Halogen Lamps. There are no plans at this stage to upgrade to LED due to the City Hall relocation.

We pay our contractor CBRE £2,602 per annum to maintain the office lighting.

A further breakdown is not available within the appropriate limit. Under section 12 of the FOI Act, we are not obliged to comply with a request if the cost of determining whether we hold the information, locating and retrieving it and extracting it from other information would exceed the appropriate limit. This is calculated at £25 per hour for every hour spent on the activities described and equates to 18 hours of work.

The below information is the energy consumption for the whole building, it is not broken down by lighting.
