Peru State College hired ADA to remodel the three story, 60,000 square foot, TJ Majors Classroom Building. The remodel included a complete replacement of the HVAC system now with a new geothermal addition; as well as upgrades to the life safety and fire systems. Windows, entryways and staircases, mechanical and electrical spaces, and interior finishes were all updated or replaced to meet modern code requirements. With this renovation complete the building will consume 50% less energy than buildings of similar size and occupancy.
