Part 2. Reduction in source energy use per unit of floor area
Baseline year energy consumption
STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.
| kWh | MMBtu | |
| Imported electricity | 83,489,669 Kilowatt-hours | 284,866.75 MMBtu |

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
The first initiative, Energy GPA, is a program that provides students in University-owned student neighborhood houses with a grade of their monthly energy use. Monthly "report cards" include electricity and gas usage and a monthly tip for energy savings. Grades are determined by comparing a house's usage against an average of that house's previous three years of energy-use data. With over 400 houses in our student neighborhood, the Energy GPA program will be a key way in which we engage students in lowering UD's overall carbon footprint.
The second initiative utilizes Housing and Residence Life's "PATH Point System," which provides students with the most points priority in housing placements, by providing students with the opportunity to watch educational videos on lifestyle changes to reduce energy usage and live more sustainably.

A brief description of energy use standards and controls employed by the institution:
The university continues to retrofit buildings with efficient LED lighting and other new energy equipment. From 2017-2020 UD, along with the DP&L Retrocommissioning Program, completed retrocommissioning projects across all university buildings.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
A major focus of the university’s green revolving fund has been to retire florescent lights in favor of LED replacement lamps. These projects have shown that it is financially prudent to replace even relatively efficient T8 lamps. Students and staff are systematically identifying building spaces where it is profitable to replace the florescent lamps and using GRF money or other funding to complete these projects. In addition to transitioning to LEDs, occupancy sensors have been installed in order to turn lights off during unoccupied periods and save energy. For several years, the university has also been replacing its high pressure sodium exterior lighting and gym lighting with LED lamps.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
The solar building at the Energy Experience Center has a ground source heat pump system that is able to heat and cool the building by exchanging heat with the ground using a series of tubes placed in vertical holes in the ground.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
The university wass an active participant in DP&L's rebate programs while they existed, especially the retrocommissioning program, which has saved millions of kWh in campus buildings since 2017. Student groups like the Campus Energy Team also participate in projects like these through the Green Revolving Fund.
