Sean Armstrong taught net-zero design at a demonstration house at Humboldt State University from 1999-2002, and has 12,000+ hours of experience as staff Project Manager with affordable housing developers Pacific Communities, Danco Communities, and the Redevelopment Agency of the City of Arcata. Sean was the first developer to use the California Utility Allowance Calculator (CUAC).


Michael Winkler designed and lives in a remodeled Net Zero house, was part of engineering teams that designed one of the nation’s first cell phone systems and the world’s most-efficient hydrogen fuel cell, and has programmed a version of the CUAC that is more accurate with netzero developments. In addition to multiple energy credentials (EIT, CEPE, HERS, BPI), Michael is a software engineer. Michael served for 8 years on the City of Arcata Planning Commission 2 years on the City’s Energy Task Force, and is currently the Mayor of the City of Arcata.
