2021 Net Zero Fellows

Our fifth annual Net Zero Fellows: Jean von Bargen Root of MWA Architects, Inc., and Jessy Ledesma of HomeWork Development. Through two fellowship grants, these industry experts will receive funding to support net-zero research in Oregon.

Jean’s research explores barriers and opportunities to advance net-zero energy in commercial-industrial developments in Oregon. With a focus on the Willamette Valley, Rogue Valley and High Desert, Jean evaluates current and future climate conditions and assesses how local development codes, standards and policies help or hinder net-zero performance in this building type. An accompanying design guide provides detailed design solutions for mixed-use office/industrial, warehouses, pre-engineering metal building and unoccupied service buildings. Jean partnered with Convergence Architecture, a COBID (Certification Office for Business Inclusion and Diversity) certified firm, to conduct and disseminate the recommendations.

Jessy will analyze new combinations of systems and technologies for affordable, resilient net-zero housing. She will explore the application of a mass plywood panel envelope, monobloc heat pump to thermally condition a high-mass floor slab and thermal storage and solar energy in multifamily cluster housing. Jessy will also coordinate with the National Association of Minority Contractors Oregon  to develop a workforce training about the fast-growing fields of mass timber and net-zero construction. Through this training, she hopes to connect diverse contractors across the state with tools and information about new construction types and net-zero building strategies. Jessy will partner with Energy Studies in Buildings Laboratory, Institute for Health in the Built Environment, Tallwood Design Institute, Swinerton Construction, and Timberlab.
