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. Gillette's portfolio consists of 6 buildings and 1 wastewater treatment facility. Energy usage at the wastewater treatment facility makes up roughly 20% of the total portfolio. The chart at the right includes the portfolio average EUI for buildings only. Since 2009, Gillette has increased energy usage in buildings by 4%. Total portfolio energy usage showed an increase of 12%. This increase is due to needed repairs at Gillette’s wastewater treatment facility, which has improved safety and efficacy processing but increased energy use since 2009. Some energy savings have been achieved by implementing outdoor lighting retrofits across all facilities. The City is initiating a number of other efforts to drive further reductions including HVAC upgrades at City Hall, an Inventory and Tracking Process to engage staff in identifying efficiency opportunities, and an energy awareness campaign in an effort to reduce plug-load.

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. There are 4 facilities that have experienced an increase in Source EUI since 2009. These facilities have been targeted for future energy efficiency improvements. Gillette built a new warehouse in 2010 that has improved by more than 10% since construction and a new heated storage facility in 2013. They are not included in the graph because they did exist in the baseline year.

Identifying Opportunities for Improvement

Facility-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. Gillette's portfolio consists of facilities using between 100 and 300 kBtu/sq. ft. in the baseline EUI values. The facilities located near or below the 0% axis may present good opportunities for further savings. Two buildings do not have a 2009 EUI and are not included in the chart.
