It’s always nice to see a project or initiative that extends well beyond what it set out to do. Chicago’s City Hall is an eleven story building in the ‘loop’ that began with the idea of a green roof as a lead by example type of project. With the planning and thought of adding a luscious green garden atop the very top floor of the building came the ideas to showcase what the garden would be able to do for other architecture around the city.
In terms of cooling the building, improving air quality of the city, and conserve energy– the city decided to replace the black tar roof with vibrant green plants that all would be able to thrive in the ‘windy city.’ These plants are also able to retain water and prevent excess runoff.
The garden provides plenty of pathways and varied heights and textures in its appearance. With over 20,000 square feet of planted space, more than $5,000 a year is saved on utility bills; and there are of course plenty of factors that also improve the city. That goes without even mentioning the curb appeal added to the beautiful building itself.
