A community centre in Derby has ditched old fluorescent strip lights in favour of energy-saving LED lights to cut costs and save energy.
With the new lamps, the St James Centre hopes to reduce its carbon footprint as well as operating costs, making it more affordable for people and institutions to rent rooms there.
The building is a base for several organisations, including a group for disabled young people and young adults, a multi-faith cultural awareness group, a nursery, and food distribution scheme run by Derby City Council.
Derby City Council contributed some £5,000 towards the refurbishment through its Bespoke project, while the Veolia Environmental Trust awarded a grant of £7,489 through the Landfill Communities Fund.
The rest of the money was paid by the St James Centre itself.
Carmel Heathcote, chief executive of the St James Centre, said: "We are delighted that the project is complete and the centre's future is now more sustainable.
"The improvements mean that we can continue to offer a range of valuable activities for the whole community for little or no price."
Paul Taylor, executive director of The Veolia Environmental Trust said: "Centres like this one play a vital role in our communities and it is great to hear that the improvements are now complete. I hope that the centre is used and enjoyed by the community of Derby for many years to come."
