After conducting a preliminary facility improvement study for Penn Harris Madison Schools, Performance Services identified several learning environment issues including high CO2 and humidity levels, temperatures with trouble maintaining set point, and high classroom noise levels. A direct result of obsolete control systems and system components that exceeded their expected useful life, Performance Services identified solutions that allowed each school to significantly reduce energy usage and create optimal classroom learning environments.
