[Greenbuilding] low flow shower heads

[Steven Tjiang]

He obviously has more money to waste and little environmental sense.  I'd
milk him for all he can pay and recommend some crazy system costing way more
than any sane person would buy. I think he needs large oversized geothermal
systems and since he will have more than enough capacity I'd tell him to get
a very heated swimming pool and jacuzzi.  Then of course, he'll need some
solar offset, so sell him a really large solar system as well.

I'm kidding!
