Figures needed to determine total building energy consumption:
| Performance Year | Baseline Year | |
| Grid-purchased electricity | 19,815.90 MMBtu | 21,279 MMBtu |
| Electricity from on-site renewables | 301.24 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) | 63,459.90 MMBtu | 63,459.90 MMBtu |
| Total | 83,577.04 MMBtu | 84,738.90 MMBtu |
Start and end dates of the performance year and baseline year (or 3-year periods):
| Start Date | End Date | |
| Performance Year | July 1, 2015 | June 30, 2016 |
| Baseline Year | July 1, 2013 | June 30, 2014 |
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):
We are finding it confusing to enter different baseline and reporting years for those areas in STARS that require it; therefore, our rationale is to find the most reliable data across all data point in STARS in a given year for our baseline, and use that. For us, that is 2013-2014. Our hope is that future STARS reports will be more easily understood by any new staff charged with STARS reporting.
Gross floor area of building space:
| Performance Year | Baseline Year | |
| Gross floor area of building space | 1,630,000 Gross square feet | 1,451,775 Gross square feet |
Source-site ratio for grid-purchased electricity:
Total building energy consumption per unit of floor area:
| Performance Year | Baseline Year | |
| Site energy | 0.05 MMBtu per square foot | 0.06 MMBtu per square foot |
| Source energy | 0.08 MMBtu per square foot | 0.09 MMBtu per square foot |
Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
Degree days, performance year (base 65 °F / 18 °C):
| Degree days (see help icon above) | |
| Heating degree days | 3,250 Degree-Days (°F) |
| Cooling degree days | 1,765 Degree-Days (°F) |
Floor area of energy intensive space, performance year:
| Floor Area | |
| Laboratory space | 25,000 Square feet |
| Healthcare space | 0 Square feet |
| Other energy intensive space |
EUI-adjusted floor area, performance year:

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):
Berea College uses building automation systems such as JCI and ALC in a number of buildings to regulate temperatures based on occupancy schedules. For example Lincoln and Emery.
In all LEED Certified Residence Halls, windows have a sensor when shut HVAC operates normally, open windows, HVAC shuts off.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Berea College has just competed a year long upgrade of nearly all of its exterior campus lighting to LED. This lighting retrofit is in addition to similar upgrades to LED made inside the campus buildings over the last few years. Together, these efforts have dramatically reduced the amount of electricity and cost associated with lighting for the college - estimated at a 65% reduction in both.
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):
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):
After conducting an energy use study in all residence halls for individual dorm refrigerators, it was determined that the college would save money by furnishing all first year residence halls with one, Energy Star dorm refrigerator per room. Up until 2015, there was no policy in place to limit the number and types of refrigerators allowed. The majority were not Energy Star, and some rooms contained two. Additionally many fridges were abandoned at the end of the year, found in dumpsters. Now, we have reduced our energy consumption and, in addition, have stopped the need for incoming first year's to purchase a fridge each year.

Data source(s) and notes about the submission:
Data regarding natural gas consumption and #2 fuel oil for buildings on campus (entered in "Energy from all other sources") are placeholder numbers; the totals for both the baseline and performance year are based on natural gas consumption and fuel oil use during CY 2016. This was the only data regarding use of heating and cooking fuels in our buildings available at the time of submission, and it allows our total energy usage for both years to be reasonable approximations of reality.
