Energy Code Compliance in Indiana

Permit stuck waiting on a seal? Apex Grid's licensed engineers provide fast Energy review-and-seal for drawings in Indiana and across the state — reviewed under responsible charge and sealed for submittal to the applicable Indiana permitting authority. Typical turnaround is 3–5 business days once we have a complete package.

Indiana's commercial energy code is state-adopted but older than most of the country, referencing an ASHRAE 90.1 / IECC vintage from around 2007–2010 with amendments. That gives us a uniform statewide compliance baseline, which we document through COMcheck or energy modeling, but the dated minimum means real savings come from designing above it. In climate zone 5A, envelope performance — continuous insulation, air-barrier continuity, and infiltration control — is the highest-value lever, followed by efficient heating plants and lighting controls. For the warehouse and manufacturing buildings central to Indiana's economy, high-bay lighting controls and efficient process heating drive the biggest operating-cost reductions. We also identify utility incentive programs that reward exceeding code, which helps justify above-minimum design on heating-dominated Indiana projects.
