What are green roofs l.jpg
What Are Green Roofs?

  • Green Roofs are roofs covered by vegetation

  • Two types of Green Roofs

    • Intensive – Heavy, expensive; capable of supporting large plants

    • Extensive – Light-weight patches of shrubbery

  • Green Roofs are advantageous for

    • Keeping buildings cooler in the summer and warmer in the winter

    • Protecting a city from combined sewage overflow during storms

    • Extend the life of a roof

The urban heat island effect l.jpg
The Urban Heat Island Effect

  • The Urban Heat Island Effect refers to the fact that cities can be up to 5-7º C hotter than the surrounding rural areas

  • This usually happens because…

    • Anthropogenic heat (Man-Made)

    • Concrete can absorb a lot of heat

    • Tall buildings increase overall surface area for heat absorption

    • Urban Canyon effect


Why new york city l.jpg
Why New York City?

  • New York City has 5 times the area of Central Park in roof space (Gaffin et al, 2004)

  • If even half of these roofs were made green, It would have significant environmental effects. (Rosenzweig et al, 2005)

My objective l.jpg
My Objective

  • My objective is to confirm LANDSAT surface temperature data at key sites of interest around New York City.

  • Measure differences between green roofs and black roofs

  • Measure how quickly surfaces heat up in New York

Further research l.jpg
Further Research

  • Get surface and air measurements over the course of a day

  • Expand measurements of surface and air temperatures to other regions of high interest
