SUSTAINABLE DESIGN

Verdant Structural Engineers (VSE), located on Codornices Creek in Berkeley, is a full service Structural Engineering firm. VSE continues the practice of Kevin Donahue Structural Engineers (KDSE), which began providing engineering services to architects, builders and owners in 2003. We provide structural drawings and calculation materials required for building permit submittals on a wide array of projects, as well as providing building consultation, expert advice and legal testimony.

VSE works on a large variety of projects ranging from home remodels to the new construction of schools, wineries and other commercial and public buildings. We specialize in projects utilizing optimal and efficient use of conventional building materials as well as projects utilizing environmentally sensitive building materials and methods such as straw bale, rammed earth, cob, adobe and bamboo. VSE continues KDSE’s history of working closely with the natural and green building community to develop standards, practices and procedures for green building practices, such as the current Straw Bale Appendix Chapter in the International Building and Residential Codes.

VSE practices collaborative design. We work closely with project design and construction teams to understand the project as a complete system, so that project goals are achieved. We balance building efficiency and design elegance with cost and environmental goals. Above all, VSE is sensitive and responsive to clients' needs.

In addition to California, VSE has practiced in the following states: Arizona, Colorado, Hawaii, New Mexico, Oregon, and Washington.

MEET THE TEAM





Kevin Donahue, SE - Principal

Kevin Donahue has been practicing structural engineering for over 25 years. Kevin’s original background is in mathematics. He earned Bachelor’s degree in Math from Brown University in 1980, and proceeded to branch out into architecture, teaching and music, performing in many well-known Bay Area music venues. He was a visiting lecturer at Cornell University in 1986. In 1989 he earned dual Master’s degrees in Architecture and in Structural Engineering and Mechanics from University of California, Berkeley. Kevin began his structural engineering career with Toft & de Nevers (later Toft, de Nevers & Lee), where he also obtained his Civil and Structural Engineer licenses. Since opening his own office in 2003, he has endeavored to marry the technical with the expressive in his engineering practice, from an interest in working with alternate and “green” building materials, to a collaborative approach to problem solving while working with his architectural and building clients.

Kevin is a contributing author to the book Design of Straw Bale Buildings by Bruce King et. al. (Green Building Press, 2006), is currently serving on a task force of structural engineers and architects charged with introducing straw bale construction to the International Building and Residential Codes, and currently resides happily in Berkeley with his wife and their daughter’s cat.

Anthony Dente, PE - Principal

As a professional engineer and VSE Principal, Anthony is committed to the effective and efficient use of material for all building systems. He strives to assist the natural and green building communities by providing leadership for the development of design procedures for natural and green materials and systems, which in turn increases the safe and effective options available to future engineers.

Anthony graduated from the Architectural Engineering program at Penn State University and moved to Berkeley, CA to practice structural design and in particular, straw bale structural design, under Kevin Donahue, SE. Anthony is a board member for the Cob Research Institute (CRI), an organization committed to the development of accessible permitting procedures for cob and other similar earthen materials. In conjunction with CRI, Anthony was the lead engineer of the currently proposed Cob Construction appendix to the International Residential Code (IRC), the first of its kind in the United States. Anthony was a working group member for the development of the first low carbon concrete building code, which was commissioned by Marin County, and organized by the Embodied Carbon Network and the Ecological Building Network. He was also contributed to the Straw Bale Building Detail book published by the California Straw Building Association (CASBA). Anthony has advised, designed, and collaborated in numerous university-based, small scale, and full scale testing programs on the structural behavior of natural materials. He has presented on these topics at various conferences including the West Coast Natural Building Conference and Earth USA.

Anthony believes that by supporting appropriate documentation and code development of environmentally sustaining options, the building community will have the tools to design against the hazards of environmentally destructive construction as effectively as it designs against other safety hazards in the building code.
