Asserting that the most viable means to radically reduce embodied carbon in new buildings is to use plant and earth-based materials, this lecture and accompanying exhibit, based on LTL Architects' (Lewis Tsurumaki Lewis) recently published book, Manual of Biogenic House Sections, demonstrates how this approach can catalyze new types of houses that reduce or sequester carbon, engage regenerative life cycles, and create healthier spaces for living.
