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. Working with EPA, DCAT led the development of EPA’s Tribal Green Building and Building Code website and a related Toolkit. 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 eight years. He led the task group that developed the ASTM E2392 Standard Guide for Design of Earthen Wall Building Systems. David served on the initial 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, Light Straw-clay, Cob (Monolithic Adobe), and Hemp-Lime construction as well as Tiny Houses,. David served for 10 years on the City of Tucson/Pima County Arizona Joint Building Code Advisory Committee. DCAT and David received ICC's 2007 Affiliate of the Year Award and a 2007 USGBC National Leadership Award. David was lead technical subject matter expert for an EPA report on resilience-based strategies and best practices to reduce building-related disaster debris. David serves on the boards of Sustainable Tucson and the Tucson 2030 District as well as on Green Advantage’s International Green Builder Education Board developing green building, resilience, and disaster-response certifications for the construction industry workforce.
