Green Construction and Rooftop Jacuzzis

Yesterday my wife, Christine, and I began the long, slow process of finding a new home. With a baby on the way in a few months, we decided to start exploring some different neighborhoods and homes to get a feel for where our future residence may lie.
House hunting (or browsing) gives me an opportunity to see what other folks are doing to their homes, and often provides me with inspiration for future design and/or build ideas. Yesterday was no different, with one home in particular really setting the bar. Upon walking in to this particular town home, the allure was immediate. The style was mostly modern, with a sleek, clean steel staircase inviting the inhabitant upstairs into an open plan with fantastic southern exposure. Without going into detail, the house was well designed from the layout to the selection of finishes and appliances. Although it was out of our price range, Christine and I could easily see ourselves in this place.
As we walked out of the house, I grabbed a final flier, and noticed that the place was advertised as a 'green project'. I wasn't entirely surprised to see this. I had noticed that the recessed lighting consisted of compact fluorescent bulbs, and that the appliances were energy star-rated. Also, the place was fairly close to the metro, which is certainly a 'green feature'.
However, as I thought about this label, I remembered seeing the rooftop with concrete pavers... with a jacuzzi.. operating full blast. There we several other building materials that featured prominently that I know (from experience) embody a pretty high carbon footprint.
As we left the place, the flier left a slightly sour taste in my mouth. Without taking anything away from the beauty of the place, I was disappointed with the marketing, since this is precisely the sales mentality that endangers the meaning of green construction.
The problem is that green comes in different shades, and those shades can be difficult to evaluate in terms of environmental performance. The fact that the project did incorporate some environmental elements was definitely a good thing, but I don't know if I'd have the jacuzzi running full blast in freezing temperatures (with nobody in the tub) if I wanted to call the place 'green'..
