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. USAA Real Estate’s office portfolio has consisted of more than more than 70 buildings and 21 million square feet since committing to the Better Buildings Challenge. Since 2008, USAA Real Estate has improved energy performance by an average of 2% each year.  USAA Real Estate has made a consistent effort year over year to improve their operational performance by using a business case strategic approach to energy conservation and efficiency. Energy savings have been achieved by implementing low-cost retrofits (lighting, vfd's, etc.) and by optimizing building operations and controls across their office portfolio.  Additionally, real-time energy and BAS monitoring on a 15 minute interval basis has driven additional ongoing performance improvements, measurement and verification of implemented measures, and anomaly alerts to quickly correct issues.

ENERGY PERFORMANCE BY PROPERTY

Looking at the percent improvement in energy performance across all properties can provide insight into how an organization is saving energy.  USAA Real Estate has achieved an energy performance improvement of greater than 6% at 39 of its properties. While there are 23 properties that have experienced an increase in Source EUI, it should be noted that many of these buildings have gone through a lease-up phase and/or more densification, thus increasing the energy demand in the building.  Concentrated effort is taken to identify opportunities for future energy efficiency improvements at these buildings.

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. USAA Real Estate's portfolio consists of properties with a range of baseline EUI values, most of which are between 100 to 300 kBtu/sq. ft. The majority of properties have shown energy improvement since 2008. The properties located near or below the 0% axis may present good opportunities for further savings.
