EEB Hub Regional Sankey Diagram: Philadelphia Authority for Industrial Development Historical and Forecast Energy by Planned Use at the Philadelphia Navy Yard
The Energy Efficient Buildings Hub (EEB Hub) is a DOE-funded center, focused on improving the energy use in commercial and large-scale residential buildings. One of the Hub’s goals has been to develop the means and methods to reduce energy use in commercial buildings by 20 percent by 2020. Understanding energy use in buildings is a key component to managing energy use at multiple scales, from the building to the city, to the region. Sankey diagrams are an accessible tool to visualize energy flows, and help identify opportunities to deploy energy saving technologies. A campus-level Sankey diagram was previously generated from 2010-2011 data for ~100 metered Navy Yard buildings to quantify natural gas and electricity usage by principal building activity. As these properties are renovated, the energy consumption and building principal activities are being updated and modified. To depict the multi-year time lapse of regional electricity distribution in the Navy Yard, LLNL generated Sankey diagrams using data from 36 properties (buildings, developments, equipment) used to develop Philadelphia Authority for Industrial Development’s (PIDC) Navy Yard Master Energy Plan (NYEMP). The diagrams presented in this report depict ~10 building use types and the yearly changes in forecasted usage in GWh from 2011 to 2022. The forecast captures increases in regional energy use from planned building additions and renovations and yearly increases for existing buildings. From 2009 to 2022, there is approximately 5.6 million square feet of planned additions and renovations. The largest addition of properties are for office (~ 2.3 million square feet for dedicated office, and larger for shared office space) and residential space (~1 million square feet). Until 2014, the largest user of energy is for flex space, reaching a forecasted 11.4 GWh. In 2015-2016, the largest forecasted user is for a data center reaching ~25.7 GWh. After 2016, the largest consumers are either for office space (reaching 63.2 GWh forecast in 2022), or heavy industry (68 GWh forecast in 2022).
