The Challenge

Hotel Monteleone New Orleans

Located in the heart of the French Quarter, the 15-story Beaux-Arts landmark Hotel Monteleone required a major HVAC retrofit while remaining fully operational. The property includes over 600 guest rooms and had to maintain comfort, aesthetics, and revenue during renovation.

  • Minimal Guest Disruption Rooms could only be taken offline in small groups. The hotel had to remain fully operational during renovation.
  • Historic Preservation Tight mechanical spaces required a compact, small-footprint solution.
  • System Compatibility The four-pipe fan coil configuration required a unified, single-source solution.
  • Phased Execution The retrofit needed to be efficient across multiple renovation phases.

The Solution

Working closely with Wink Engineering and the hotel’s facilities team, Griswold Controls recommended installing Automizer® combination control valve coil piping packages on the four-pipe fan coils.

Key Advantages

  • Single Source for Coil Components Eliminates coordination issues and ensures system compatibility.
  • Multi-Function Valve Combines actuated temperature control and flow limiting in one compact package.
  • Small Footprint Ideal for historic buildings with tight mechanical space.
  • Equal Percent Control Mirrors coil heat transfer curves for superior temperature regulation.
  • Pre-Assembled & Ready to Install Reduces labor, installation time, and jobsite handling.

I told Gary to get the Griswold Control valves on order and let my purchasing department know how much the bill would be.

Because the Automizer features automatic flow control, the retrofit could be accomplished a few rooms at a time without affecting the rest of the hotel's circuits — making it the ideal product for hotel renovation. In a manual balance application, the entire system would have had to be rebalanced every time a room was taken offline. By installing the Automizer, the hotel minimized room downtime, substantially reducing the potential for lost revenue.

The Results

Phase 1 (2002): The Monteleone Hotel renovated guest rooms with 288 Automizer CPP2A packages on horizontal units, plus a number of 3-way Unimizer® actuated control valves on vertical units.

Phase 2 (2004): The hotel ordered an additional 112 Automizer coil piping packages. The re-order decision was automatic — a direct result of satisfaction with Phase 1 performance.

Because the Automizer features automatic flow control, rooms could be renovated individually without requiring a system-wide rebalance — protecting guest comfort and preventing revenue loss.

The success at the Monteleone Hotel demonstrates how a technically superior product can simplify phased renovation in occupied, operating buildings — protecting revenue while delivering measurable long-term performance gains.

It's nice when you are selling a quality product like Griswold Controls. You put your time and effort into getting that first order, and then getting the next order just takes a few minutes on the phone.

They work great! I'm very satisfied and look forward to buying Griswold Controls for every new FCU in the hotel as we continue to renovate additional rooms.
