Swackhamer was invited to speak at a National Academy of Environmental Design Workshop on Sustainable Materials on January 16 and 17, 2009. Video of the workshop presentations has just been posted online here. Swackhamer's 20 minute presentation of Drape and Cloak Wall, which can be viewed here, is informative not just of these two projects, but also, more generally of HouMinn's design process. Other presenter's included Billie Faircloth from Kieran Timberlake Architects, Sheila Kennedy from Kennedy Violich Architects, Blaine Brownell from Transtudio, and John Carmody from Minnesota's Center for Sustainable Building Research. Tom Fisher, Dean of Minnesota's College of Design, moderated the workshop.
