Did you know…

America's 81 million buildings consume more energy than any other sector of the U.S. economy,

including transportation and industry?

Page 3: Green Roof Technology

Why is this fact relevant?

“The Heat Island Effect”Heat radiates from city surfaces, industrial processes, and automobiles raising the immediate atmospheric temperatures. Higher temperatures create atmospheric instability, increasing chances of rainfall and severe storms. Also, high temps stir up dust, it gets trapped causing smog

High energy bills Unsafe air quality Sewer system flooding and water

contamination Sound penetration

Green roof technology is capable of alleviating these problems.

• A green roof is:• A green roof is:

Vegetation cover on a roof surface.

Extensive and Intensive

• 2 main types:

Type 1: Extensive Type 1: Extensive

• Shallow depth (typically 2-4 in.)

• Low growing, often broad leaved plants

• Plants with ability to withstand harsh weather conditions

• Extremely low maintenance

• Minimal weight load

• Depth of 1ft. or more• Involve high maintenance

plants such as trees and shrubs

• Irrigation system often necessary

• High maintenance• Considerable weight load• Less common • Commonly accessible by

public

Environmental, Economic, & Psychological Benefits:

• Reduced Rain Water Runoff = less chance of contaminated water or storm sewer flooding (a major issue)

• Cleaner Air Quality• Improved Insulation = lower heating and cooling costs

• Water Purification • Provides a Habitat for various organisms

• Reduced Rain Water Runoff = less chance of contaminated water or storm sewer flooding (a major issue)

• Cleaner Air Quality• Improved Insulation = lower heating and cooling costs

• Water Purification • Provides a Habitat for various organisms

• Sound Absorption• Cooler air = less smog (Urban Heat Island Effect)

• Aesthetic Appeal• Extended roof life (by 20 years or more!)

• Recreational Space• Potential to Recycle Wastewater

• New Jobs (horticulture specialists,manufacturers, installation experts, etc.)
