IDS Center Recommissioning

Project Background

As Minnesota’s tallest building, the IDS Center, has long demonstrated a commitment to environmental stewardship—from a full-scale recycling program to Metro Transit events on commuting options, green cleaning methods in public spaces, environmentally friendly purchasing practices, and multiple energy building management initiatives that conserve energy.

In 2015, the Center for Energy and Environment began multi-year investigation to assess and improve energy efficiency in the 57-story office tower.

Investigation

CEE engineers identified numerous energy-saving opportunities to help the IDS Center conserve energy and cut back on energy-related costs, by studying millions of data points collected through input from building operators onsite measurements, and extensive trend analysis.

Improvements

Engineers discovered a wide range of opportunities to maximize air handling, optimize lighting and mechanical devices, and adjust electronic programming for lights and climate controls throughout the building. In addition to the pump system upgrade, CEE contributed its engineering expertise and analysis to all aspects of the improvements noted above. These efforts earned substantial rebates, lowered the building’s operating costs, and reduced its carbon footprint.

In May 2018, the IDS Center received a “Recognition of Excellence Award” from Xcel Energy for the efficiency projects completed through this commissioning study. The awards were designed to honor Xcel Energy Minnesota business customers who have demonstrated an exemplary commitment to energy efficiency.
