Team Member Biographies

With an internal staff of over 20 professionals operating the Ceres-based headquarters, Southern California division, and the Nevada division. California Living & Energy's Leadership Team consists of four professionals:

William Lilly, President

Bill Lilly first entered the energy-conservation industry in 1976, when he started working with Weathermaster Insulation providing energy-efficient design work for an array of different structures from refrigeration buildings to residential subdivisions. After subsequent years of career growth, Mr. Lilly left Weathercaster in 1981, which would turn out to be right in the middle of the worst recession since The Great Depression, and started his own insulation-contracting firm, which went onto insulate millions of square feet of walls, ceilings and floors in existing homes. Over time, his firm grew to a point where larger insulation contractors became interested in acquiring his company. The company's insulation component was sold in 1988 to Western Insulation, which was subsequently purchased by MASCO Corporation, all the while Mr. Lilly retained ownership of the energy calculations division that would later become a part of Mr. Lilly's other company - California Living & Energy.

During this period, Mr. Lilly secured his contractor's license in three separate designations: general, mechanical and insulation.

For California Living & Energy, it has since grown into an industry leader in both service and stature by providing energy calculations throughout California, Colorado, Nevada and New Mexico. Over time, California Living & Energy has broadened its scope of services by expanding into engineered mechanical design and HERS inspection as well as providing liability-reducing risk management programs for builders. California Living & Energy has produced more than $1.6 million in HERS testing revenue annually.

Mr. Lilly is a certified Calcerts and Resnet Rater, Resnet Green Rater and Certified CHEERS Energy Analyst. He is on the board of directors of CalHERS, a rater support organization, and Teen Challenge, a prisoner support ministry. He is also a National Comfort Institute certified air balance inspector. In 2009, Mr. Lilly was invited to give a presentation on green assessments for multi-family public housing communities at two United States Department of Housing and Urban Development (HUD) conferences in California.

Mr. Lilly brings a wealth of experience and education in the practical aspect of energy conversation, and by launching two companies amidst recession, he has proven his leadership ability. Bill is married to Anita who manages the accounting department and has one daughter, Lexine who is the contracts administrator.
