Episode 169: Neighborhood Preservation by Distillations Podcast

Majestic old buildings testify to the rich history of cities across the world. But why do some of these buildings seem unaged while others rot just blocks away? The answer, sometimes, is science. On today’s episode of Distillations we’re looking at the role of chemistry in neighborhood preservation. First, producer Alex Lewis shares the efforts of a Philadelphia-based congregation trying to save its crumbling church. Then we talk to the Delaware Valley Green Building Council’s Heather Blakeslee about how architects and developers restore aging structures to live new and greener lives.
