TECHSTYLE HAUS
Urban and architectural designer for a $500,000, 800 square-foot passive solar house installed at Solar Decathlon Europe 2014 and Domaine de Boisbuchet. Core team member in all project phases from concept to full build, presentation, and construction. Participated in team charrettes to integrate an energy positive systems design and a Passive House approach to core and shell and to orientation. Managed urban design and mobility strategy, team communication, and project documentation.
Organized team coordination meetings and workshops, gave oral presentations to potential donors, and built the house 3 times (and disassembled 2 times) with the full 40-person design-build team. Provided on-site translation with our French-speaking partners during construction.
