Passive strategies (I thought) were generally preferred since they tend not to place much of a burden on resources we think of as scarce, or pose risks we would rather avoid.

There are hundreds (thousands?) of reasons why this is so, but the reason I used the word loathing in an earlier reply is that I can't in 2017 in good conscience go along with that default position without first investigating whether an alternative that is less fraught isn't available. I thought that was the essence of Green Building.
