Case Study: Longhorn Steakhouse achieves guest comfort and energy savings with 75F

Longhorn Steakhouse - Customer Case Study

Longhorn Steakhouse, part of Darden Restaurants, needed a better way to address guest comfort issues and support long-term energy efficiency goals at two Illinois locations in Orland Park and Bolingbrook. The restaurants were experiencing temperature imbalances in dining areas, and their existing programmable thermostats and manual adjustments were not able to handle the varying heat loads effectively. 75F was brought in to provide a more systematic solution.

75F installed Dynamic Airflow Balancing and Outside Air Optimization to automatically maintain more consistent temperatures and improve ventilation control. Within 24 hours, managers reported a noticeable improvement in comfort, with the system conditioning the building without human intervention and delivering year-over-year utility savings. Using Facilisight reporting, Longhorn Steakhouse was also able to verify temperature performance, with occupied areas maintained within 2°F of the target and unoccupied areas allowed to drift for added energy savings.
