The three key views from the hilltop site drive the three-sided figure of this exhibition hall. At its center, a suspended glass courtyard brings people up to a viewing deck and allows light and fresh air into the exhibition space. (Principals: Craig Scott and Lisa Iwamoto. Team: Shirley Chen, Robert Tranter, Bin Zhang, Celia Chaussabel. Role: Led the design of the first floor, stair cores, and landscape; renderings and graphics; coordination with the local design institute; documentation using Rhino.Inside.Revit; detailing of facade system and interiors; construction drawing set)

Manual of Biogenic House Sections is a book of drawings documenting fifty-five houses built with carbon-sequestering materials and other low-carbon strategies such as reuse. In addition to digitally modeling and drawing the houses, I researched and diagrammed the life cycles of each featured biomaterial and the conventional extraction-based materials being critiqued. I also helped to develop an embodied and sequestered carbon estimation methodology for select houses and designed the layout of the book. (Principals: Paul Lewis, Marc Tsurumaki, David J. Lewis. Team: Kyle Reich, Celia Chaussabel, with contributions from from Jingyuan Zhang, Alena Nagornaia, Max Heint, Grace Lee, Austin Madrigale, Julia Medina, and Zhiqian Xu. Role: Modeling, drawing, carbon calculations, architect contact for redlining, communication with ORO)

The materials of the standard American single-family house, shown in the previous spread, serve as a reference for the biomaterialbased houses selected for the book. I researched and diagrammed the extraction-based materials that contribute to the high embodied carbon and inability to reuse and recycle materials. Biomaterials like straw, by comparison, come from renewable resources and are compostable at the end of their use in a building.

“Verbiest” by AgwA Architects is an example material reuse built in Brussels in 2020. The existing industrial structure was retained, but being much too large for a residence, the enclosed, unconditioned spaces were kept to a limit. The rest of the unconditioned spaces function as a greenhouse, a ceramics studio, and a deck. The existing concrete structure is reinfoced with braces made of wood. Concrete slabs and terra cotta roof tiles were reused in-situ. Stones, roof tiles, and railings are reused from a nearby site in the Brussels area.

Axon drawing of “Verbiest”. I found this house on Opalis, a database of material reuse dealers, case study projects, and manuals regarding material reuse (https://opalis. eu/en/projects). The architect provided documentation, which I used to digitally model and draw the house.

For each of the 55 houses, a representative section “chunk” was selected to illustrate the unique tectonic conditions that result from building with biogenic materials.

Carbon calculations of select houses, using volumes measured from the digital models. To develop a methodology, we compared many existing databases and systematically selected the most relevant information. The calculations are challenging because of the range in carbon data from database to database, the lack of data on carbon-sequestering biomaterials, and the insufficient construction details for some of the houses.
