Early in the construction phase, the decision was made to pursue LEED certification for Pioneer 360. A central consideration to LEED certification for this project was the fact that the new business center was constructed on a previously developed property in the midst of older retail and commercial building facilities. This "infill development" presented a variety of challenges unique to Pioneer 360 that were addressed throughout the construction process, not the least of which was the demolition of an 800,000 SF abandoned mall that covered much of the property.
