1 Exploring Tomorrow’s Technology in Roofing

Extensive greenroof technology has been tried and proven in Europe more than 30 years but has not been fully developed for North American climates. Perennial plant ground covers and shallow growing substrates on roofs: 1) improve energy efficiency by reducing interior temperature fluctuations, 2) significantly extend roof membrane life, 3) ameliorate storm water run off, 4) provide beauty & wildlife habitat, 5) reduce pollution and the heat-island effect, 6) are used as a place for advertising, recreation, herb & food production, education, physical and mental therapy and treatment of gray water
