Getting eco-friendly in Longton

In the back streets of Longton, they've renovated the old America Hotel (in front), and built on to it a brand spanking new structure - now taken over by CORE (Centre of Refurbishment Excellence). 
CORE is a sort of learning centre for people in the construction industry wanting to know about eco-friendly methods.

I suppose the CORE building itself had better be a good example of what they are promoting, or it would fail in its own mission!
Actually, inside and out, it looks okay.
