But do they make useful contributions to environmental and sustainable design objectives?  I do not know and would like to hear of any scientific evidence and environmental impact assessments. My guesses are (1) Patrick Blanc&#8217;s green walls use more energy for pumps\/materials\/manufacture than they save through insulation (2) more of Patrick Blanc&#8217;s green walls use tapwater than use rain which has fallen on the site (3) Patrick Blanc&#8217;s green walls make useful contributions to noise attenuation and dust capture (4) the contribution of Patrick Blanc&#8217;s green walls to biodiversity is negligible (5) one could achieve more environmental benefits, though less beauty, by using climbers.<br \/>\nThe above example is on the <a href=\"http:\/\/www.athenaeumhotel.com\/system_pages\/nav_bars\/header\/about_us\/plant_wall.aspx\">Athaneum Hotel in Picadilly, London<\/a>.<br \/>\n<a href=\"http:\/\/mars.stephenalton.com\/posts\/sustainable\/sustainability-misguided-architects-and-greenwalls\">Stephen Alton<\/a> shares my scepticism.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Patrick Blanc has made a great contribution to the technology of green walls, with beautiful results.
