Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 589,219.46 MMBtu | 486,392.42 MMBtu |
| Electricity from on-site renewables | 0 MMBtu | 0 MMBtu |
| District steam/hot water (sourced from offsite) | 0 MMBtu | 0 MMBtu |
| Energy from all other sources (e.g., natural gas, fuel oil, propane/LPG, district chilled water, coal/coke, biomass) | 763,818.14 MMBtu | 776,939 MMBtu |
| Total | 1,353,037.60 MMBtu | 1,263,331.42 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2017 | July 1, 2018 |
| Baseline Year | July 1, 2007 | July 1, 2008 |
A brief description of when and why the building energy consumption baseline was adopted (e.g. in sustainability plans and policies or in the context of other reporting obligations):
The baseline was adopted to align with our larger greenhouse gas inventory, GHG reduction goals and other report baseline years.

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency (e.g. outreach and education efforts):
UD is completing a trial behavior change study with a focus on energy efficiency in our General Services Building. Once the trial is complete, we will assess opportunities to roll it out to other buildings on campus.
A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
UD ustilizes DDC based building automation systems in majority of campus buildings. Occupancy sensors,timers and other lighting controls are implement where possible.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
UD lighting standard is LED with 0-10V dimming where applicable
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
All new buildings take passive solar opportunities into account during design to meet our LEED Silver or better standards. UD also has a large density of mature trees which offer significant passive solar benefits, especially on our core campus and around The Green.
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
n/a
A brief description of the institution's initiatives to replace energy-consuming appliances, equipment and systems with high efficiency alternatives (e.g. building re-commissioning or retrofit programs):
UD has completed a comprehensive Facilities Condition Index, which will inform (among other initiatives) the opportunities for recommissioning and retrofit programs.
