Here in the U.S., the percentage is far less and in fact, that number is not even officially documented. But it is on the rise. Some more well-known examples include the <a href="http://www.calacademy.org/academy/building/the_living_roof/" target="_blank">California Academy of Sciences</a> and the <a href="http://www.asla.org/ContentDetail.aspx?id=25362" target="_blank">American Society of Landscape Architects' HQ</a>. These are indeed admirable, but they are costly and difficult to replicate. Trying to persuade a client about the benefits of relatively inexpensive, passive, more sustainable building strategies is difficult enough and honestly a green roof is anything but.</p>
