To me the ultimate test was what the author says about LEED.
Is he being critical of LEED? Yes.
But it has been criticized for devolving into more of a game in which racking up the most points sometimes takes precedence over producing the greenest building.
The author does a good job of listing some other issues with LEED and makes a final point.
Another criticism of LEED is that the certification process can be very expensive and time consuming.
The author looks at many of the issues with a critics eye on what to do and why.
If you are looking for a guide to greener/sustainable design, this book is worth checking out.
