There are optimal velocities for different types of pitches. For instance, you want your change-up to be thrown at a slower speed than your fastball. Pitchers' velocities often vary. Tim Wakefield, a knuckleballer of the Boston Red Sox, for instance, has a slow fastball, clocking in the high 70s at most.

In summer, the green roof protects the building from direct solar heat. In winter, the green roof minimizes heat loss through added insulation on the roof. Energy conservation translates into fewer greenhouse gas emissions. Benefit: Green roofs improve air quality Plant leaves trap dust particles from the air, and evapotranspiration cools ambient temperatures. Less ground level ozone + less heat = less smog.
