Since the Carbon Trust assessed the Market Place venue last year a number of improvements have been made, including installing movement sensors so lights are not left burning in empty rooms.

South Holland District Council head of economic and community development Sue Bolter said revolving entrance doors will help save heat and also form part of a new lobby refurbishment at the start of next year.

She said: "This has been on the cards for a while and we have been incrementally increasing our energy efficiency in the building.

"The revolving doors are part of refurbishing the whole of the foyer area.

"The centre has been there for ten years and has had regular paintwork done but it needs to be brought up to modern standards."

The centre, which last year was visited by more than 150,000 people, also has a seven-day temperature setting so that when the building is not in use on a Sunday the heating can be turned off.

Mrs Bolter was unable to say how much money the new doors are expected to save the council or how much they will cost as the authority has put the work out to tender.

The South Holland Centre refurbishment is expected to take place in January when it could be closed for a few days.

The council has submitted plans for revolving doors to the planning department but says disabled access will be maintained through traditional doors.

Mrs Bolter added that the council has a number of other schemes in the pipeline for its other buildings and has installed a wood chip boiler at the West Marsh Road depot.
