Studies of these rooftop technologies are often located in hot climates and do not assess their full environmental consequences. Further, current studies tend to focus on one technology and often do not evaluate the full range of technology options using a systematic framework with common assumptions and boundaries. This article evaluates the environmental performance on a life cycle basis of white roofs, green roofs, and roof\u2010mounted PV in the cold Canadian climate. Solar PV demonstrates the highest environmental performance in all impact categories considered (see complete list in\n                    <jats:italic>Results<\/jats:italic>\n                    section) and is the preferred option from an environmental perspective. Green roofs result in beneficial environmental impacts, although much less significant than those obtained with PV, and are the only rooftop technology that reduces both heating and cooling energy use. The environmental performance of white roofs in cold climates is strongly affected by the heating penalty (i.e., the increase in heating energy use resulting from the high solar reflectance). Although white roofs have been proven an outstanding option in warmer climates, in cold climates, net negative environmental impacts lead to white roof technology not being recommended for general applications in cold climates. A sensitivity analysis shows that the conclusions in this study provide robust insights across Canada and cold climates in general.\n                  <\/jats:p>","DOI":"10.1111\/jiec.12269","type":"journal-article","created":{"date-parts":[[2015,4,6]],"date-time":"2015-04-06T15:39:38Z","timestamp":1428334778000},"page":"249-262","source":"Crossref","is-referenced-by-count":56,"title":["Sustainability of Rooftop Technologies in Cold Climates: Comparative Life Cycle Assessment of White Roofs, Green Roofs, and Photovoltaic Panels"],"prefix":"10.1007","volume":"20","author":[{"given":"Eduard","family":"Cubi","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nicholas F.","family":"Zibin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sarah J.","family":"Thompson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Joule","family":"Bergerson","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2015,4,6]]},"reference":[{"key":"e_1_2_7_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.enbuild.2004.11.013"},{"key":"e_1_2_7_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.enbuild.2013.02.063"},{"key":"e_1_2_7_4_1","volume-title":"Cost and performance data for power generation technologies","author":"Black & Veatch","year":"2012"},{"key":"e_1_2_7_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.rser.2011.07.104"},{"key":"e_1_2_7_6_1","unstructured":"Caneta Research Inc.2011.Addendum to performance simulation of proposed changes to NECB relative to MNECB ASHRAE 90.1 2007 and ASHRAE 90.1 2004.
