Jamestown, LP: Energy performance

Energy Performance
Average Annual % Improvement1%

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.  Jamestown's portfolio consists of 52 buildings and 10.2 million square feet. The company has improved energy performance by an average of 1.6% from a 2014 baseline, making progress towards a goal of 20% by 2024.  Each year, energy assessments are conducted throughout the portfolio with the goal of identifying projects that support savings.


Looking at the percent improvement in energy performance across all properties can provide insight into how an organization is saving energy. Jamestown has achieved energy performance improvement of greater than 10% at 14 of its properties. There are 15 additional properties that have experienced an increase in Source EUI and these have been targeted for energy efficiency improvements. Future efforts will focus on largest drivers of energy use in the facilities. In many instances, tenant controlled spaces represent a majority of the energy consumption in Jamestown owned buildings.  This provides an opportunity to identify projects that benefit both the landlord and the tenant and support energy efficiency goals, and leverage high performance or "green lease" language to help get project implemented.


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. Jamestown's portfolio consists of properties with  a wide range of baseline EUI values, most of which are from 120 to 300 kBtu/sq. ft. The majority of properties have shown energy improvement since 2014. The properties located near or below the 0% axis may present good opportunities for further savings. Jamestown also utilizes real time interval data and other building level energy management tools to support operational improvements.
