Honeywell energy savings for hotel independently validated

A collaboration between a utility, hotel consortium, and Honeywell set out to measure and compare energy savings between standalone and Honeywell INNCOM networked energy management systems. The results raised eyebrows.

The key to occupancy-based energy management

On average, more than 30% of hotel rooms in the U.S. are unrented at any given time. And even when rented, guestrooms are often unoccupied throughout much of the day.* Honeywell saw this as an opportunity to leverage its deep experience with building control systems in the hospitality industry to help hotels owners and operators manage their energy usage, while still meeting guest expectations for a convenient, comfortable experience.

The D.C. Sustainable Energy Utility entered into a collaboration with Hilton Worldwide, Clearview Hotel Capital and Honeywell to objectively study the energy differences between standalone and networked energy management systems at the Washington Hilton in order to validate Honeywell’s claim that an INNCOM Networked EMS can deliver 25-40% HVAC energy savings in guest rooms.**

The scalable energy management and hospitality IoT platform from Honeywell provided a great option to install a basic, standalone in-room energy management system that could be networked and integrated with the hotel’s property management system (PMS) at any point for comparison.

Then, the D.C. Sustainable Energy Utility team worked independently from the Honeywell team, metering these same test rooms. Their results were reported to Hilton and Clearview independently. The results? Guestrooms with the INNCOM networked EMS consumed, on average, 41% less energy through the HVAC system than rooms without PMS integration.

The conclusion? To help maximize energy management, hotels should consider replacing existing standalone energy management systems with a networked EMS, while new hotels will also do well to install a networked EMS with a property management system integration.

A networked EMS is a clear choice for better energy management now and in the future.
