A3C - Collaborative Architecture: Extensive/Intensive green roof built in 2008, covers 2,000 sqft.
ANN ARBOR, MICHIGAN - The A3C green roof was born out of their commitment to sustainable design and to practice what they preach. The green roof acts as a learning lab and educational facility for the community and A3C clients. The green roof is visible from a rooftop conference roof and is available to local government and non-profit organizations by appointment. Numerous green roof products and systems have been incorporated into the roof displaying a variety of options available. Research components have also been integrated into the roof to monitor thermal performance and energy consumption. Green Roof Service helped A3C with the green roof specifications, review of materials, and installation.
ABC Carpet and Home: Extensive green roof built in 2010, covers 10,000 sqft.
BRONX, NEW YORK - As the leaves begin to fall, a new roof is being raised as Green Roof Service and the Sustainable South Bronx prepare for the installation of ABC Carpet and Home's series of green roofs at its Bronx location.
Building a green roof on a warehouse can be a difficult task since the building is a wide open structure with little support for the roof. To circumnavigate this issue, we designed green roof strips to go on every other support beam of the roof. By keeping the green roofs on the strongest segments of the roof we were able to cover 10,000 square feet of the roof without over stressing the roof.
Experimentation boxes featuring a green roof and regular roof set up have been fitted with temperature sensors and tipping buckets. These sensors will collect air, surface, and runoff data as part of an ongoing observation comparing these two systems.
Bronx County Courthouse: Extensive green roof built in 2006, covers 10,000 sqft.
BRONX, NEW YORK - In September 2006 Bronx Borough President Adolfo Carrion Jr. and the New York Power Authority (NYPA) unveiled New York’s first green roof on a municipal building.
This has quickly become the center of attention for a lot of people and New York City’s Mayor Bloomberg has chosen this green roof for many of his press conferences.
Green Roof Technology designed, specified and supervised installation and maintenance of the green roof. Green Roof Technology also conducted a two-year scientific monitoring program on the roof to measure storm water retention and temperature.

This naturalistic set up incorporates a comprehensive energy and water monitoring system replacing the former river stone ballast. The project was initiated by students, who were also involved in the design, planting and research program.
W.P. Hickman was the general roofing contractor. Unfortunately W.P. was bankrupt in 2008. In the newly formed company Viridian Systems has this project list as their reference but this doesn't seem correct because they certainly have nothing to do with. Actually the client paid W.P. Hickman for a long term warranty that is no worthless and the new company is not will continuing it. In the roofing business we often see these almost criminal practices that are against any respectable business behavior.
