"Preservation is not only about restoring historic monuments, but also about recycling durable buildings; even contemporary structures can have their exterior envelope performance enhanced.  The character of our urban areas, landscape and society is defined by what we save, giving us a sense of place as well as the continuity of history.  At the same time, preservation is about managing change.  Historic buildings are the backdrop for the new structures we create."
