GREEN ROOF EXPERTS TO SPEAK IN DES MOINES NOVEMBER 19, 2002 Roofs covered with plants will be the subject of a public forum sponsored by the Des Moines Founders Garden Club on Tuesday, November 19, 5:30-8 p.m. at Meredith Corporation, 1716 Locust Street. The event is free. Attendees must register in advance by calling 515-277-2183. The experts who will speak are Georgia landscape architect Linda S. Velazquez, founder and publisher of Greenroofs.com, a portal for green roof technology, and Canadian Kaaren Pearce, experienced designer and installer of green roofs. There will be additional participation from the Chicago mayor's office about their City Hall rooftop garden. Ms. Velazquez will present an overview of green roof technology and its application internationally. She has studied green roofs in Europe and recently lectured on green roofs at the University of Malmo, Sweden. Ms. Pearce will focus on North American green roof projects. She will describe her experiences with different green roof systems, discuss research findings, preview upcoming systems, and provide plant information. Attendees are invited to share comments, questions and information. Green roofs are not a new idea -- early Icelandic homes were roofed with grass -- but it's an idea of growing interest, as communities search for environmentally, socially and economically sound ways to develop. The benefits of green roofs can include less energy used by buildings, reduction of the 'urban heat island effect' (the overheating of cities in summer due to building materials like asphalt and concrete which absorb the sun's heat), reduction of storm-water run off, cleansing the air of particulate matter, providing aesthetic and recreational amenities for those who live and work in cities, and providing new habitat opportunities. Since the new Des Moines Public Library, designed by London architect David Chipperfield, may have a green roof, the Des Moines Founders Garden Club has organized this forum on the subject to promote educated discussion and decision-making at all levels in our community. Additional financial support has been provided by Barb and Dave Hurd, Georgia and Robert Helmick, Kay and Bob Riley, and the Iowa Chapter of the American Society of Landscape Architects. In-kind assistance has been provided by the Downtown Community Alliance and the Marriott Hotel. To register for the event call Marie Louise Kane at 515-277-2183. Erin E.
