wool:IS (The Wind Tool) is the pocket calculator which determines building response as per the international wind-loading code ISO 4354.

The perfect tool to aid engineering professionals, students and teachers in the calculation and verification of the design of mid-rise and tall-buildings.
wool:ISO is possibly the best thing since the invention of the Boundary Layer Wind-Tunnel

+ Design your own building and calculate along-wind, cross-wind and torsion responses for two orthogonal wind directions:
* Base Overturning Moments
* Base Shear Forces
* Torsion
* Maximum Tip Deflection

+ Calculate and plot along-wind, cross-wind and torsion responses over the height of the building:
* Point Loads
* Shear Forces
* Deflection
* Torsion

+ Easy to use interface with minimal inputs required from the user:
* Basic building dimensions (HxLxD)
* Frequencies of vibration, assumed structural damping and mode shape exponents
* Upstream terrain category and regional reference wind speed

+ Advanced controls available for the experienced engineer:
* Time-averaged interval of response (T)
* Building density

+ Outputs important parameters used in the calculation of building response for user reference
+ Save projects and edit later
+ SI Units
+ Help Buttons for more information on the definition of inputs
