Contemporary European-Style Downtown Hotel

Cutting energy costs to compete more effectively in a crowded market


  • The award-winning luxury hotel featuring 661 rooms and suites, and 65,000 square feet of event space, opened in 1988.
  • Although the hotel is strategically located at a prestigious address, competition was increasing as newer hotels added thousands of rooms to the downtown market.
  • Hotel management recognized the need to drive down operating costs in order to ensure long-term profitability. Among other initiatives, they decided to attempt to reduce energy use associated with space conditioning, guest amenities, and kitchen and laundry operations.
  • The HVAC system was more than twenty years old, suggesting that the hotel might be a prime candidate for retro-commissioning.


  • The hotel owner engaged us to perform retro-commissioning with the stipulation that guest comfort and convenience must remain the highest priority throughout the project. Our goal was to optimize energy use, maintaining or enhancing conditions, rather than to conserve as much energy as possible.
  • After we identified a preliminary set of energy-saving opportunities, site staff selected eight measures for further study. We fine-tuned our analysis, and they managed implementation using their preferred contractors.
  • Our verification process confirmed that we helped the hotel achieve annual energy savings of 5% for electricity and 4% for natural gas—without adversely impacting the guest experience.
  • The eight implemented measures yielded a combined simple payback in fewer than eighteen months.
