an unusual story - not really related to our main topic eco-travel - but a great example of renovation of a building for a greener environement - and that's not a hotel, that's a convent !
The renovation includes grass- roof tops, use of recycled concrete and glass, efficient bulbs etc. and you know what .... they even grow their (organic) vegies on the roof top !
All this in New York City,
So if a convent can do it, why not hotels ?
