Michaels Rolls Out Siemens EMS Platform Extensions

Michaels Stores Inc. is rolling out a series of Siemens advanced extensions to the Site Controls Energy Management System (EMS) across the arts and crafts retailer's chain of stores.

Since deploying the Siemens system in 2006, Michaels has seen substantial reductions in energy consumption across its building fleet of more than 1,000 stores. The additional savings created by the new advanced-capability deployments are expected to bring total EMS-related savings to more than 30%.

“Energy is our second-highest store-level line item expense behind labor,” said Robin Moore, vice president for store development and construction at Michaels. “Through regular KPI reviews and process improvements provided by Siemens' Client Services team, we have been able to sustain and increase our energy savings over time, and these new extensions will take those savings even further. We have been very pleased with both the advanced technology and the consultative approach provided by our long-standing partnership with Siemens.”

The fleet-wide expansion was preceded by a thorough system analysis after a 30-site pilot and subsequent 200-site expansion. A comprehensive measurement and verification study following these deployments validated the savings.

The extensions include three main items:

  • Intelligent Demand Control Ventilation (i2DCV), which enables global enthalpy with existing HVAC units without expensive hardware retrofits

  • Psychrometric controls, which dynamically adjust temperature setpoints to factor in temperature and humidity while maintaining customer comfort

  • Lighting automation upgrades, which enable more precise control of lighting circuits such as employee areas and stocking zones.

The extensions will provide Michaels a cash-on-cash payback of 20 months, and an ROI exceeding 90%. In addition, the investment will drive further reductions in Michaels' carbon footprint.
