A3C’s Office Building was sold in early 2015 to a tech group who wanted to develop a major incubator space for start-up tech firms by consolidating three buildings. A3C’s office space and in particular the UrbEn Retreat, A3C’s rooftop conference space and outdoor deck, were very attractive additions to this proposed project. A3C completed the UrbEn Retreat in 2008 and for the last seven years it has hosted numerous conferences and training sessions on building sustainably. It was part of A3C’s LEED Gold Office renovation.
