Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 262,630.55 MMBtu 261,562.58 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) 336,301.17 MMBtu 77,318.17 MMBtu
Total 598,931.72 MMBtu 338,880.75 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, 1989 June 30, 1990

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):

When we completed our first Carbon Footprint Analysis and Climate Action Plan in response to the American Colleges and Universities President's Climate Commitment, we chose 1990 as our baseline year because of consistency with the Kyoto protocol and because we developed our first major sustainability initiative (the recycling center) in that year as well.


Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 442,058.67 Gross Square Metres 401,906.65 Gross Square Metres

Source-site ratio for grid-purchased electricity:
3.14

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 1.35 MMBtu / GSM 0.84 MMBtu / GSM
Source energy 2.63 MMBtu / GSM 2.24 MMBtu / GSM

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
0

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 2,463.89 Degree-Days (°C)
Cooling degree days 723.89 Degree-Days (°C)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 10,050.11 Square Metres
Healthcare space 3,148.67 Square Metres
Other energy intensive space

EUI-adjusted floor area, performance year:
472,726.51 Gross Square Metres

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

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):

Temperature standard is 68-72. Construction specifications for new construction requires occupancy sensors. We have Johnson Controls thermostats that enable us to do timed temperature regulation in 50% of our buildings.  


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

LED conversions are ongoing. Most lighting has been converted to LED or fluorescent.Replacement is on an as needed basis ISU has a lighting LED standard of Holophane.


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):

We explored cogeneration technology with our natural gas boiler for heat production on campus, but realized that we don't currently push enough steam throughout the year to make cogeneration economical.


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):

We are currently committed to pursuing LEED Silver certification for any new construction, but we are also pursuing LEED Silver certification for our renovations as well. We are currently in a cycle of renovating our four largest residence halls (the four Sycamore Towers) to LEED Silver with renovation of one tower per year. Mills Hall has been completed and Bloomberg is under renovation currently. Cromwell will be next and Rhoads will be completed at the end of the four year cycle.
