The bill mandates that the Department of Administrative Services in Iowa contract with a certified technician to conduct mechanical insulation energy audits for all state-owned buildings. These audits are required to be completed by January 1, 2028, and subsequently every four years. The audits will focus on identifying any missing or damaged mechanical insulation, assessing compliance with the American Society of Heating, Refrigerating and Air-Conditioning Engineers Standard 90.1, estimating emissions and energy losses due to insulation issues, and providing cost estimates for remediation along with the expected return on investment.

Additionally, the bill defines "mechanical insulation" as the materials, facings, and accessory products associated with mechanical systems, including piping and ventilation. This initiative aims to enhance energy efficiency in state buildings and reduce environmental impact by ensuring proper insulation is maintained and compliant with established standards.
