1 Design wind pressures above represent the net pressure (sum of external and internal pressures) applied normal to all surfaces.

2Values shown are for exposure B. For other exposures, multiply values shown by the following factor: exposure C: 1.40 and exposure D: 1.66.

3 Linear interpolation between values of tributary area is permissible.

4Values shown are for an importance factor I = 1.0. for other values of I, multiply values shown by I.

5 Plus and minus signs signify pressure acting toward and away from the exterior surface, respectively.

6 All component and cladding elements shall be designed for both positive and negative pressures shown in the table. 7Notation:

a: 10% of least horizontal or 0.4 h, whichever is smaller, but not less than 4% of least horizontal dimension or 3 ft. b: Roof height in feet (meters).

Renewable Energy 101

Renewable energy is energy that is generated from sunlight, rain, tides, geothermal heat and wind. These sources are naturally and constantly replenished, which is why they are deemed as renewable. The usage of renewable energy sources is very important when considering the sustainability of the existing energy usage of the world. While there is currently an abundance of non-renewable energy sources, such as nuclear fuels, these energy sources are depleting. In addition to being a non-renewable supply, the non-renewable energy sources release emissions into the air, which has an adverse effect on the environment.
