The China Daily [6] reported late last week that all new residential construction in the massive powerhouse city of Shenzhen must install solar powered water heating system.

For those who have been lucky enough to have visited this dynamic and vibrant city, you will quickly get my point, in that there are very few, if any, new buildings under 12 storeys!
