Since Hilton Worldwide introduced its LightStay sustainability measurement system across its hotel and resort properties, the company has saved more than $74 million in utility costs.
Those results specifically came through the following:
- 6.6 percent cut in electricity consumption
- 7.8 percent reduction of carbon output
- 19 percent cut in waste output
- 3.8 percent reduction in water usage
LightStay is a management system that allows the hotel to track all the various projects across the company, enabling it to measure the environmental impact. The platform is built as as social media network, so that employees can share best practices with one another from property to property. So far, there are more than 1,200 different projects in the system. Hilton expects that amount to double in 2012.
“Thus far, LightStay has provided us with a platform to measure hotel performance and economic improvement, proving to be invaluable given today’s increased operational demands and resource constraints,” said Christopher Nassetta, president and CEO of Hilton Worldwide, in a statement.
Some of the new initiatives on drawing board include installation of energy-efficient chillers, boilers, building automation systems and water reclamation systems. One example is the onsite co-generation system being built by the New York Hilton, which will offset approximately 54 percent of its electricity needs and 33 percent of its thermal needs.
On a corporate level, Hilton Worldwide has adopted a plan to reduce energy consumption, carbon dioxide emissions and waste output by 20 percent. Its goal for water conservation involves a 10 percent reduction drom direction operations.
