THE greenest building in Britain has celebrated its second birthday with a team aiming to make the city the UK's most energy-efficient.

The PlanetYork team visited the York Environmental Community Centre, in St Nicholas Fields, Tang Hall, to mark the occasion.

The building is built entirely of sustainable materials, recycles all waste and uses energy produced by wind turbine and solar panels.

Fuel bills run at a fifth of the normal rate.

It is used as a community facility aimed at making York more environmentally aware - and has had more than 3,000 school children through its doors already.

"Education is the key to ensuring that the environment is at the top of everyone's agenda," said Gordon Campbell-Thomas, the centre's co-ordinator.

"We have to be aware that we are citizens of York and of the world and what we do has an impact on the planet."

PlanetYork is a year-long project aimed at substantially cutting the amount of energy used in the city. Campaign manager Laura Collins said: "York Environmental Centre shows just what can be achieved when a community pulls together to make the environment a priority."
