Orange County expertise
Orange County includes dozens of incorporated cities, each with its own plan check process and permitting requirements. EGI’s engineers work directly with local building departments across the county, preparing MEP documents that meet California Title 24 energy code requirements and each jurisdiction’s specific submittal standards. This local plan check experience helps keep projects moving through review without avoidable delays.
A significant part of our Orange County work has been Proposition 39 school HVAC upgrades, where EGI has designed mechanical system replacements and modernizations for public school campuses under the state’s energy efficiency funding program. This is a genuine area of strength for our firm: we understand the scope constraints, energy savings documentation, and phased construction schedules that Prop 39 school projects require.
Beyond education, EGI has extensive experience with retail and mixed use centers, including large enclosed and open air malls, as well as hospitality properties such as hotels. Across these sectors, our approach is the same: coordinate closely with the design team, follow California’s energy code requirements, and produce documents that support an efficient permitting path.
