"---" indicates that no data was submitted for this field

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 59,566 MMBtu 68,553 MMBtu
Electricity from on-site renewables 4,910 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) 126,374 MMBtu 126,374 MMBtu
Total 190,850 MMBtu 194,927 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 June 30, 2018
Baseline Year July 1, 2004 June 30, 2005

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):

2005 was adopted as our baseline year because it represents the baseline we used when signing the Presidents' Climate Commitment. It also represents a year where we know we have accurate and complete GHG data.


Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 1,900,250 Gross Square Feet 1,634,997 Gross Square Feet

Source-site ratio for grid-purchased electricity:
3.14

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.10 MMBtu / GSF 0.12 MMBtu / GSF
Source energy 0.17 MMBtu / GSF 0.21 MMBtu / GSF

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
19.83

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 5,776 Degree-Days (°F)
Cooling degree days 1,117 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 45,788 Square Feet
Healthcare space 0 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
2,066,720 Gross Square Feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
13.40 Btu / GSF / Degree-Day (°F)

Documentation (e.g. spreadsheet or utility records) to support the performance year energy consumption figures reported above:
---

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):
---

A brief description of energy use standards and controls employed by the institution (e.g. building temperature standards, occupancy and vacancy sensors):

The Energy Management System (EMS) has timers integrated within it that cover many of the building spaces on campus. There are also a number of stand-alone timers, however, few are used because the EMS is used instead.

Denison has a occupancy use standard that includes temperature set-points and set-backs when spaces are occupied and unoccupied.


A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

Denison is in the process of switching most lighting from CFL and T5/T8 bulbs to LEDs. Areas with lighting that is "on" more often are being prioritized.


A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

Many of our newer buildings including those constructed at the Denison Homestead utilize passive solar designs to reduce heating costs and to take advantage of day light.


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):

As a matter of course, Denison replaces appliances with Energy Star rated ones. As buildings are renovated, Denison utilizes its Green Revolving Loan fund to ensure high efficiency systems and technology are deployed.
