Wakefield Council will temporarily close its county hall building in a bid to save on rising energy costs.
The council will close the building by the start of next month and will move staff to neighbouring buildings at Wakefield One and Wakefield Town Hall.
Wakefield's cabinet member with responsibility for property, Darren Byford, said: 'By reducing energy usage, we are able to cut our fuel bills, which will support us to maintain important services that our residents rely on, at a time of severe financial pressures.
'While the building is closed, a low level of heating will be used throughout the winter months to ensure this important historic building is well maintained.'
The council is also considering what other buildings could be closed to save on energy costs.
