The InterContinental San Francisco opened in February 2008 and is a LEED EBOM Gold Certified building.

The InterContinental San Francisco has already benefited from traditional energy conservation and efficiency measures. Additional measures would have been difficult without compromising the comfort of hotel guests. Harry Hobbs, IHG's Western Area Director of Engineering, was looking for a way to tackle high demand charges due to load spikes, which are not addressed through standard energy efficiency measures.

After hearing about the Stem system, Harry decided to deploy systems in both San Francisco InterContinental hotels. Harry was able to take advantage of the California Self-Generation Incentive Program (SGIP) to cover 60% of the system installation cost.

Stem's solution was installed in November 2012 and immediately began leveraging the proprietary combination of big data, predictive analytics, and energy storage to effectively "hybridize" the hotels by intelligently switching between battery power and grid power to reduce energy costs.

Independent verification of results was conducted by corporate staff using a third party revenue-grade meter and simulated load. As a result, IGH has committed to purchasing Stem systems for is California portfolio of 16 hotels in 2013, with a projected savings of $2.2 million over the next 10 years.
