Green roofs are a familiar concept among high-performance building designers and other EcoGeeks, but what about a mobile green roof moving through a city?
A project called Bus Roots takes the idea of green roofs and installs it on a bus. The project is the graduate thesis of NYU student Marco Antonio Castro Cosio. A mobile science lab called Bio Bus is the host for this project.
The Bus Roots project uses an extensive green roof system similar to that used for buildings and covers the 340 square feet (31.6 square meters) of bus roof with shallow trays of plants in growth media.
Bringing a mobile patch of plants through the city offers a list of potential benefits, including mitigation of heat island effect, CO2 absorbtion, oxygen production, and aesthetic value.
