"The quest for sustainability will increasingly concentrate development in cities, generating a greater fusion of old and new styles of architecture, especially as policy incentives are implemented that encourage major additions to existing buildings. Charles F. Bloszies, AIA, author of a forthcoming book from Princeton Architectural Press exploring this trend, will lead preservation architect Bruce Judd, architect/historian Anne-Catrin Schulz of Colliers and real estate broker Dan Cressman of Grubb & Ellis in a discussion of the complex issues involved. Co-sponsored by AIA San Francisco."
