About Us

Company History

Founded in 1982 as primarily an insulation company, Apperson Energy Management has evolved over the last 30+ years to become a leader in local building performance contracting.  As building standards have changed, energy efficiency measures have become more important, and our understanding of building science has grown, this company continues to be on the cutting edge of home performance.

Jim Apperson, Company Owner

Jim started his career in the construction field in 1967 as a laborer installing underground telephone pipelines.  He worked on a variety of projects until 1972 when he opened his own company as a framing subcontractor.  That company was purchased by a large construction company in 1975 and Jim stayed on as job superintendent in charge of as many as 20 simultaneous projects.

In 1982 Jim moved to Northern California and obtained his General Contracting B-1 State license.  The following year he added the C-2 Insulation specialty license, and C-17 Window and Glazing specialty license in 1988.

Jim has not only built custom homes, has performed extensive remodel projects and room addition projects, but he has also continued to operate a thriving insulation and energy management company.

When the first HERS training was available in 1993, Jim was a member of the graduating class.  He has continued his education from there and has a large number of certifications:  HERS II whole house rater from CalCERTS, Building Analyst and Envelope Professional from BPI, Home Performance Energy Star Program, Build it Green Building Professional, and is proud to be one of a select few companies with the designation of Building Performance Contractor as designated by PBC-CEC.
