I am considering purchasing a new home in San Diego from a community called Del Sur.  They seem to offer the latest in green building technology.  They have tankless water heaters and solar powered energy systems as well as require at least 50% of the landscaping to be drought resistant.  I was wondering if anyone had more information on these features.  This seems like a great community to be a part of, if only everyone else could do the same. 

I've heard about the Del Sur project, it sounds great! I've been considering purchasing a tankless water heater and have found alot of good info on the web. A helpful site for me is http://www.tanklesswaterheaterguide.com. Good luck!
