Andrew presented "Gardens by the Bay, Singapore" as his keynote address.  Gardens by the Bay consists of three distinctive waterfront gardens in the heart of Marina Bay that will define Singapore as the world's premier tropical garden city.  The presentation showed the scope and content of this spectacular 101-hectare project with particular reference to the innovative use of vertical planting and ecological management systems.



Charlie Miller, P.E.
Principal of

Philadelphia, PA, USA. Charlie Miller has 30 years of experience in projects related to civil and environmental engineering.  In 1997, Charlie formed Roofscapes, Inc. (now Roofmeadow) to introduce green roof technology as a new tool for managing stormwater in urban and developing areas in the United States.  He has written four new ASTM standards that are specifically intended for use by the green roof industry, and is currently at work on the new ASTM Standard Guide for Vegetated Green Roof Systems.  Charlie’s firm provides project delivery services, including feasibility studies, design consulting, preparation of construction documentation, construction management, and long-term maintenance and support for green roof installations.  Projects have included the design and installation of the well-known green roof for Chicago’s City Hall.  Roofscapes, Inc. supports and supervises a national network of landscape contractors that specialize in green roof installation.  It also partners with several national roofing manufacturers in order to offer complete green roof assembly packages.  Over 200 green roofs have been installed by Roofmeadow contractors. Consulting services offered by Roofmeadow focus on providing affordable green roof options for controlling stormwater and nurturing green space in cities.

(PRGD) which is responsible for 80% of all the green roofs built in the island of Puerto Rico. Projects range from small ecological roof to big scale intensive greening.  Since 1996, more than 150,000 sf of green roofs have been installed in Puerto Rico, but not all have survived the harsh environment of the tropics, especially in the extensive category.  As this new wave of green roof construction is reaching the Caribbean market many doubts and misconceptions have taken over local designers.  Should green roofs be designed here equally to those in northern climates?
