Pressure Coefficient

c_{p} = \frac{p - p_{\infty}}{\frac{1}{2} \cdot ρ \cdot v_{H}^{2}}

p	Static pressure at the point which the pressure coefficient is being evaluated
p_∞	Static pressure in the freestream (here: p_∞ = 0 Pa)
ρ	Air density (here ρ = 1.2 kg/m³)
v_H	Freestream velocity at the building height (here: v_H = 12.7 m/s)
