Soldata Energy Consulting was founded in 1980 in Santa Rosa by Bill Mattinson, widely respected for his knowledge and service in the field of building energy analysis in California.

Throughout his career he was active in helping to shape building energy policy in both state and national arenas. Bill retired in the spring of 2013, and Sarah Pernula and Sean Plikuhn are now the owners and principals of Soldata.

Soldata occupied the same offices on College Avenue in Santa Rosa for 20 years. In the fall of 2013 the building sold and we moved to an office on Capricorn Way in the Lakes Business Park. As of January 2022, we are operating entirely remotely.
