Aaron Betsky is an American architecture critic and director of the Virginia Tech School of Architecture and Design. He considers architecture to be more than buildings. He argues that we need to rethink, reuse and repurpose the buildings we have, not just add more. Architecture should not be a matter of building up but of questioning, expanding, and "decommissioning." Betsky thinks about this mainly in relation to the environment; we should not, he says, waste non-renewable resources and land. We must also realize that what makes up our home in the modern world is no longer buildings but the images, forms and spaces that allow us to be active players and take a critical stance in our society. This lecture will present his attempts to explain the modern world through answers to architectural issues.
