Five-Year Capital Plan Helps Chicago High-Rise Cut Energy Use
June 24, 2015
The 125 S. Wacker upgrades began with the building's control system in order to maximize efficiencies as the rest of the new MEP equipment was brought online. Subsequently, new boilers, a chiller plant upgrade and the addition of VAV equipment was championed, all allowing the building to heat and cool its spaces based on actual occupancy numbers, providing variable and part-load performance abilities.
Still on the docket for the second half of 125 S. Wacker's five-year plan: an area cooling tower upgrade, the addition of integrated controls and sensors for the building's lighting system and more. Currently, two years into the five-year strategic plan, 125 S. Wacker has raised its Energy Star rating by 12 percent and counting.
"It's really about understanding the building as the asset of our client. We needed to bring in the appropriate tools, technologies and mechanical systems to achieve that," says William Schuch, senior vice president, midwest regional engineering manager, Jones Lang LaSalle, property manager for 125 S. Wacker. "Tying that all together with a global vision will help them achieve where they want this asset to be in five to seven years: to be fully leased and to be energy-efficient, comparable to other buildings of its type."
