On January 27, the National Building Museum held a "Sustainability Roundtable" as part of its ongoing For the Greener Good lecture series. Architectural Record Editor in Chief Robert Ivy, FAIA, and National Geographic Editor Dennis Dimick, along with Museum curator and roundtable moderator Susan Piedmont-Palladino, AIA, discussed the effect of climate change on the built environment, the natural world, and politics. If you didn't get to ask a question during the presentation, or even if you didn't attend it at all, you still have a chance to learn more from the panelists, who will be taking questions until February 24 about their views on "the future of green." Their answers to selected questions will be posted on the Museum's Web site in late February. Watch a video of the roundtable discussion or submit your question now.
