DESCRIPTION:A free seminar by Denis M. O’Carroll\, ARC Future Fellow and As
 sociate Professor\, School of Civil and Environmental Engineering\, Water 
 Research Laboratory\, Connected Waters Initiative\, UNSW Sydney.\n\nTalk A
 bstract: Green roofs have been used for centuries to insulate buildings an
 d beautify urban environments. European countries\, especially Germany\, h
 ave adopted green roofs use in modern buildings\, helping raise awareness 
 of their many potential benefits. Green roofs have been shown to: effectiv
 ely reduce and filter stormwater thereby decreasing the burden on urban se
 wer systems\; provide insulation and lower roof surface temperature leadin
 g to a decrease in building energy load\; extend the life of a roof by dec
 reasing the temperature fluctuations which cause roof damage\; and to impr
 ove air quality by decreasing CO2 levels. Green roofs are becoming popular
  in North America as they are effective tools for managing stormwater runo
 ff in urban areas. However\, the implementation of green roofs in North Am
 erican urban environments remains underused\, in part due to a lack of cli
 mate appropriate green roof design guidelines.  A greater understanding of
  how green roofs perform with respect to fundamental stormwater management
  processes\, such as stormwater retention and peak flow attenuation\, is r
 equired. This study investigated the impact that differing climates have o
 n the retention performance of three green roofs in three distinct Canadia
 n climates (i.e.\, London\, Calgary\, and Halifax). Data were collected ov
 er 2.5 growing seasons.  The impact of climate on stormwater retention wil
 l be discussed in addition to the extent to which green roofs attenuate st
 ormwater peak flow. \n\nThis talk is based on a paper by the same title au
 thored by: Denis M. O’Carroll\, Andrew W. Sims\, Clare E. Robinson\, Charl
 es C. Smart\, James A. Voogt\, Geoffrey J. Haye\, Jeremey T. Lundholm and
