Project Challenge:

Hilton sought a software solution to measure, analyze, and manage utility consumption across its large global portfolio. Hilton partnered with ei3 to establish a comprehensive utility management platform, based on ei3’s IoT solutions. This custom-built solution predicts hotels’ energy, water, and waste usage and tracks actual consumption against these predictive models.

LightStay is an innovative data-driven platform to measure social and environmental impact:

Utilizes machine-learning algorithms that continuously combine real-time operational data with complex models trained on historical information to forecast future energy consumption levels and evaluate operational efficiency. Automatically send alerts when a hotel falls below the expected performance level. Management is then prompted to take remedial actions.

In the nearly 100 years since its foundation, Hilton has established the global benchmark for excellence in hospitality. Today, Hilton maintains a diverse portfolio of 14 brands comprising nearly 5,400 properties in 106 countries.

In 2001, Hilton engaged ei3 to assist with its energy consumption. The resulting solution, LightStay, has since won numerous awards and is now mandatory for every Hilton property around the globe. LightStay significantly contributes to Hilton’s Corporate Sustainability Goals.

Any enterprise who wishes to monitor the use of resources can benefit from ei3’s capabilities in gathering, aggregating, and comparing operational data against modeled ideal usage to reduce cost and energy consumption while helping the environment.
