Carlos Santamaria

California has certainly been the primary state in the US where Optimal Building has conducted the majority of building assessments and energy efficiency audits. With over 50 million square feet of office space assessed, California remains the number one state where energy reduction opportunities exist. With "Energy And Water Efficiency Ordinances" in effect at major cities such as Los Angeles, San Francisco, San Diego, San Jose, Sacramento and other municipalities, California dominates in its efforts towards high perfromance building operations that result in meeting the states goal of Zero Net Energy use.
