The Public Service Building (PSB) is the headquarter building for WE-Energies, one of the most prominent utilities in Wisconsin. Located on 231 W. Michigan Street in the heart of downtown Milwaukee, WI, the PSB was originally built in 1905 as the first unified electric power utility in the nation, known then as the Milwaukee Electric Railway and Light Company. In 1938, the company was renamed Wisconsin Electric Power Company, and in 2002 became WE-Energies. 

The PSB underwent an extensive multi-million-dollar renovation in the mid-1990s and was retrofitted with many energy efficiency measures to qualify for the ENERGY STAR for superior energy performance, including:

• Replacing 21 separate air handlers with one single unit, which consumes far less brake horse power.
• Upgrading the entire HVAC system, including the installation of a new variable air volume (VAV) distribution system and replacing motors on the air handling unit with a fewer quantity of high-efficiency motors.
• Upgrading the controls system so that energy managers can control all set points, which increases energy efficiency and reduces costs.
• Relamping and reballasting 100 percent of lighting from incandescent and fluorescent T-12s to T-8s.
• Ensuring lights are off when the building is unoccupied with time clock sweeps.
