Marriott International, Inc. is a leading lodging company with more than 3,400 lodging properties in 68 countries and territories. Ranked among the Fortune 500, Marriott also has been recognized as one of the “greenest” big companies in the U.S.


When two chillers started to fail inside a 30-year-old Marriott hotel, the building operator assumed that a one-for-one replacement would provide the most sensible solution.

However, the manufacturer’s engineers had doubts. Suspecting that an upgrade of the entire mechanical system would be a wiser investment, Trane—the manufacturer—advised contacting RTM Engineering Consultants to gain insights that only an engineering consulting firm could provide.


To determine the best solution for the client, RTM started by conducting a complete system audit—including analyzing energy usage and projecting the energy payback realized over time if a new system was installed.

The audit revealed that simply changing out the chillers would actually be more expensive over time, versus upgrading to new technologies for all mechanicals: heating, cooling, domestic hot water, ventilation and controls.

“One-to-one was not going to be the best solution,” says Marcin Jakubowski, RTM Associate. “In proposing new technologies, we were able to show the savings that would be realized by meeting current standards for energy efficiency—from less consumption to reduced maintenance.”

For all its clients, RTM looks at the larger picture. That consultative approach is part of RTM’s Signature Method, which ensures responsiveness, quality and adherence to schedule and budget, while always delivering the right design for the need.

“We try to understand current problems, as well as future needs,” Jakubowski says. “We then work to design appropriate solutions that are based on our careful analysis. We don’t take anything for granted. We double check and verify.


Sensitive to the financial realities of a major capital investment, RTM offered several different options to the client.

Among them, RTM engineers showed how it would be possible to do a full system upgrade in phases. The solution would allow the hotel to remain in full operation through construction and also spread out the hotel’s financial outlays, thus easing the impact on cash flow.

In the end, the client chose that custom, multi-phase solution to ensure its mechanical systems would operate effectively and efficiently for decades to come.

The multi-phase project is complete, including commissioning, and RTM’s solution has proven to be a success.
