The DOA has incorporated the requirements of the Executive Order into Indiana's standard instructions to designers for projects on state-owned buildings. Efficiency can be demonstrated through adherence to any of the following standards:
- A rating of Silver on the USGBC LEED rating system
- A two-globe rating on the Green Building Institute Green Globe rating system
- An EPA ENERGY STAR building rating
- An equivalent rating under a system accredited under the American National Standards Institute (ANSI)
The order also requires that renovations or repairs of existing buildings achieve the maximum efficiency level that is cost-effective based on an analysis of construction and operating costs over the life-cycle of the building. Renovations are likewise meant to be carried out with green building guidelines in mind.
The design standards were last revised in June 2014.
