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

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 114,498 MMBtu 125,353 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) 335,413 MMBtu 389,311 MMBtu
Total 449,911 MMBtu 514,664 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, 2010 June 30, 2011

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):

N/A - Baseline year not before 2005. OP5 and OP6 have different performance years due to separate energy savings initiatives. The Performance year for OP5 showcases consumption at the completion of a phased-in performance contract period that began in FY10/11, but the data reported in OP5 come from within the past three years. The OP6 performance year showcases the energy consumption upon completion of a CHP plant; a separate energy savings initiative that has been put on hold in years FY14/15 and FY15/16 due to the drop in natural gas prices.


Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 3,382,891 Gross Square Feet 3,483,468 Gross Square Feet

Source-site ratio for grid-purchased electricity:
1

Total building energy consumption per unit of floor area:
Performance Year Baseline Year
Site energy 0.13 MMBtu / GSF 0.15 MMBtu / GSF
Source energy 0.13 MMBtu / GSF 0.15 MMBtu / GSF

Percentage reduction in total building energy consumption (source energy) per unit of floor area from baseline:
9.98

Degree days, performance year (base 65 °F / 18 °C):
Degree days (see help icon above)
Heating degree days 8,414 Degree-Days (°F)
Cooling degree days 268 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 109,538 Square Feet
Healthcare space 22,900 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
3,647,767 Gross Square Feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
14.21 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):
---

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

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):

In July 2013, Northern Michigan University built a cogeneration plant that uses local wood chips to produce 87% of the campus's thermal needs and up to 16% of the electrical load.


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):
