W.J. O’Neil Teams Up With PPMG to Save Energy Costs at Landmark Detroit Building

Updated energy systems at One Detroit Center save 24% on utility costs

Livonia, MI — John Guardiola, Vice President of Engineering at Portfolio Property Management Global (PPMG), knew exactly who to call to update the energy systems at the downtown Detroit landmark building, One Detroit Center: Joe Colleran and his team of experts at W.J. O’Neil Company.

After an exhaustive evaluation of the energy requirements of the building, Guardiola had determined changes in two areas could produce significant energy savings: an upgrade of the existing energy management system, and the addition of Variable Frequency Drives (VFD) on all motors for air handling systems.

The W.J. O’Neil team began by installing a state-of-the-art web-based energy management system. Every piece of equipment in the HVAC system is controlled by the system and because it’s web based, monitoring can be done from a remote location and changes can be made easily and quickly. The result is a greater efficiency with instantaneous information from a building management system.

Next, the Variable Frequency Drives were installed on all the major air handling systems. “With an advanced control strategy we were able to optimize the use of all systems,” said Colleran, “resulting in considerable energy savings.”

“Remarkably,” said Guardiola, “all of the work was done with zero interruption of tenants.”

The project took eight months and the savings were substantial. “We have experienced an overall 24% savings on all of our major utilities,” said Guardiola. “The new system allows us to maintain tenant comfort while at the same time save energy.”

Environmental projects like the One Detroit Center are the specialty of W.J. O’Neil. The company was recently awarded GreenStar designation by the Mechanical Service Contractors of America (MSCA) after meeting stringent guidelines for environmental responsibility throughout the company. W.J. O’Neil is only one of only 29 contractors in the country to be so honored.
