The American Institute of Architects (AIA) and the Association of Collegiate Schools of Architecture (ACSA) are dedicated to the INTERSECTION of Education, Research and Practice. Since 2015, we have offered Intersections Symposium, a series of research sessions derived from a competitive, peer-review process, which address a specific theme. This Proceedings addresses BOTTOM-UP SOCIAL CHANGE: Materials | Buildings | Community and is the product of the 2019 Intersections Symposium held June 2019, at the AIA Conference on Architecture in Las Vegas.
