Presented at the 2022 ACEEE Summer Study on Energy Efficiency in Buildings, this paper analyzes the adoption of holistic energy management systems by two leading hotel groups, Loews and IHG. 

Loews Hotels selected eleven properties to participate as a cohort in the U.S. Department of Energy’s 50001 Ready program, and IHG selected their Intercontinental New York Times Square hotel.

Based on the ISO 50001 energy management system standard, the 50001 Ready program provides a selfpaced, no-cost methodology and supporting tools for organizations to create a structured system for continual energy improvement.

The participating IHG and Loews hotels found significant value in having continual improvement processes in place that further their sustainability objectives and help ensure continuity through any future organizational changes.

Both organizations plan to implement 50001 Ready across their brands. This paper provides an overview of the lessons learned by these two organizations, and makes a business case relevant to others in the hospitality industry as well as other commercial buildings for using the 50001 Ready process to implement energy management systems.
