David Eisenberg co-founded and has led the Tucson-based nonprofit Development Center for Appropriate Technology (DCAT) since 1992. DCAT launched their program Building Sustainability into the Codes in 1995 seeking to create a sustainable context for building codes. David’s wide-ranging building experience—from troubleshooting construction of the high-tech cover of Biosphere2, to conventional concrete, steel, masonry, wood, adobe, rammed earth, and straw bale construction—has grounded DCAT’s codes and standards work in real-world building experience. David served two terms on the U.S. Green Building Council (USGBC) Board of Directors where he founded and chaired USGBC’s Code Committee for nine years. He led the task group that developed the ASTM 2392 Standard Guide for Design of Earthen Wall Building Systems. David served on the drafting committee for the International Code Council’s (ICC) International Green Construction Code. David co-authored The Straw Bale House book, helped write the first load-bearing straw bale building code, and helped develop and gain approval for the International Residential Code (IRC) Appendices for Strawbale Construction, Tiny Houses, Light Straw-clay, and Cob Construction. David serves on the boards of Sustainable Tucson and the Tucson 2030 District.
