Hilton Worldwide: LightStay

Hilton is to be applauded for its LightStay initiative. The company not only had the vision to have ambitious sustainability goals, but developed and effectively implemented LightStay as the enabling technology to achieve them.

LightStay is Hilton Worldwide’s proprietary corporate responsibility performance measurement platform. It was developed to calculate and analyze the environmental and societal impact of every Hilton Worldwide branded hotel in their communities. The platform measures energy use, water use, waste output, and carbon output at every Hilton Worldwide hotel around the globe.

Each Hilton hotel is required to track and complete improvement projects throughout the year. The LightStay environmental and energy management system simplifies energy, water, and waste performance into simple scores, and also provides information on trending and benchmarking. The tool allows hotels to track their goals and progress against those goals. Although it makes complex calculations in the background, LightStay’s simplified user interface makes it accessible to team members.

LightStay tracks historical energy and weather data to forecast future energy consumption levels and predict the impact of performance on cost. This allows hotels, owners, and management groups to take corrective action. The system cross-references the data hotels submit with expected performance to send automatic alerts to hotels when performance falls below expected levels.

The platform measures across more than 200 building and operating sustainability best practices. It manages energy and water modeling for every hotel, and calculates energy, water, and waste efficiency performance. LightStay is available on laptops and mobile devices, and can aggregate data and share insights from more than 4,800 energy efficiency projects.

The platform has helped Hilton Worldwide aggregate information across more than 4,600 hotels in 102 countries. LightStay has allowed every Hilton hotel to be certified to the ISO 14001 environmental management standard and the ISO 50001 energy management standard. In the six years since LightStay was initially launched as a brand standard, Hilton Worldwide has reduced energy consumption by 14.5%, water consumption by 14.1%, and waste output by 27.6%. LightStay has also allowed Hilton Worldwide to save $550 million during that time.
