MGM Resorts International: Energy performance

PORTFOLIO ENERGY PERFORMANCE

Better Buildings Challenge Partners strive to decrease portfolio-wide source energy use intensity (EUI) and to increase the percent improvement compared to a set baseline. MGM Resorts International's portfolio consists of 17 buildings and 60 million square feet. From 2010 to date, MGM has improved energy performance by 14%. These savings have been derived across many property operations including building automation retrofits, central plant retro-commissioning, high-efficiency boiler/burner replacements, plate & frame conversions, VFD retrofits, high-efficiency lighting projects, employee engagement, and other energy conservation measures.

ENERGY PERFORMANCE BY PROPERTY

Looking at the percent improvement in energy performance across all facilities can provide insight into how an organization is saving energy.  Since 2010, MGM has achieved energy savings of greater than 10% at 8 of its properties, while one has experienced an increase in source EUI. Although similar energy improvement strategies can be found across MGM's portfolio, most are customized applications. These property-specific energy reduction strategies are integrated with development schedules and centered on new technologies and operational best practices.

IDENTIFYING OPPORTUNITIES FOR IMPROVEMENT

Property-level energy performance metrics, including EUI and percent improvement to date, are critical to track progress over time and identify opportunities for additional energy savings. MGM's portfolio consists of properties with a wide range of baseline EUI values, most of which are from 200 to 400 kBtu/sq. ft.  Overall design and diversity in operations contribute to the variability in property EUI.  During retrofit projects, these areas are identified for increased levels of metering/monitoring to verify and benchmark energy savings. In particular, MGM has added significant electrical and thermal sub-metering capabilities at each of its central plants to collect detailed operational data. This meter data is analyzed and used to identify successful operational strategies and areas in need of further optimization. Additionally, MGM continues to maximize and duplicate recent distributed energy installations such as co-generation systems and solar arrays.
