Marriott Launches Automation Program to Cut Energy Consumption
Marriott International and Constellation Energy bring forth an agreement to develop nearly 23 megawatts of load response capability across more than 250 Marriott-managed hotel properties in the mid-Atlantic, New England, New York, Texas and California. Load response is the reduction of electrical consumption in response to high wholesale electricity prices, system resource capacity needs or system reliability events.
Constellation’s load response program is designed to improve energy efficiency and reduce electricity costs at Marriott properties, while ensuring guest comfort through expanded building automation capability and customized load curtailment strategies.
“Marriott International sees this program as a direct link to our global sustainability efforts,” says Robert Bahl, vice president of engineering and facilities for Marriott International, Americas.
“In addition to load response, the associated automation of this program will help to dramatically improve the energy efficiency of our hotels, saving an estimated 1.2 million kilowatt-hours of electricity annually.”
As part of the agreement, Marriott will leverage Constellation Energy’s VirtuWatt energy management system in concert with existing building automation to track electricity usage, bid directly into demand response markets and automate load curtailment strategies.
Marriott properties may elect to receive financing through Constellation Energy’s load response program to defray the upfront cost of demand response related equipment upgrades, as well as take advantage of load-based utility incentives in markets where available.
“Constellation Energy worked with us and our partners for more than a year to develop a load response program and a customized technology solution platform to complement our specific business objectives and diverse portfolio of hotels,” says Douglas Rath, energy director for Marriott International, Americas.
“By leveraging Marriott’s existing building controls systems, vendor relationships, utility and Constellation Energy incentive opportunities, we are able to expand our automation capabilities, increase facility efficiency, drive participation in load response programs and accelerate Marriott’s sustainability initiatives.”
In 2010, Constellation Energy and Marriott conducted a load response analysis and pilot at 17 Marriott properties, which identified technology requirements and laid the groundwork for this national scope load response program.
Furthermore, through a partnership with Automated Logic Corporation, Constellation Energy will implement indirect load control at Marriott properties where ALC systems are installed.
Constellation Energy’s VirtuWatt platform will enable Marriott properties with other brands of automation to implement pre-set curtailment scenarios for building systems such as generation, pumping and HVAC, based on load shortages, electricity usage or real-time pricing.
A groundbreaking interface provides facility operators an intuitive web-based interface for selecting specific curtailment scenarios on an as needed basis, to match daily business demands.
VirtuWatt also provides Marriott International with a centralized system for load control at multiple sites, an enterprise-view of electricity usage and data grouped by independent system operator or regional transmission organizations.
