The Alamo Sierra Club hosts a free screening of Wagging Tale Productions' The Greenest Building. Narrated by David Ogden Stiers, the hour-long doc explores the role of historic buildings in creating a sustainable culture. Through interviews with architect Jean Carroon, green building consultant Ralph DiNola, preservationist/economist Donovan Rypkema, and others, the film touches on the impact of demolition on America’s environmental and cultural heritage, the importance of historic preservation and adaptive reuse, strategies for determining which buildings warrant saving, and the uncertain concept of “sense of place” in today’s society. The screening is free and open to the public. Free, 6:30pm Wednesday; Lion’s Field Adult and Senior Center, 2809 Broadway, San Antonio.
