And it is exactly those kind of buildings the Community and Environment Award's Environmental Design category seeks to reward.

It is for that reason that Kilner Green Woodworks, of Hanson Lane, Halifax, made the shortlist for their Eco Studio in Leeds.

The timber building, insulated with sheep's wool, collects and recycles rainwater, and has a solartube, was described by judge John Furbisher as "an exciting design and a beautiful place."

The new Holy Trinity CE Primary School, Halifax, was also flagged up for a shortlist place. The curved building is designed to capture sunlight while landscaped gardens provide an eco-classroom for youngsters. Lights switch off automatically and there is efficient underfloor heating.

Mr Furbisher said: "The impact of this building is not only in creating something for now but for also winning over young hearts and minds."

Completing the line-up will be The Melting Pot, Todmorden, a Victorian mill which has been transformed into one of the most environmentally efficient buildings in the district. Energy consumption is currently only 12 per cent what it was in 2005.

Pam Warhurst said: "Owners Harmsworth, Townley & Co have done so much good to this building it is really quite breathtaking and must have been at some considerable cost to themselves."
