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

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 19,469.20 MMBtu 20,041.80 MMBtu
Electricity from on-site renewables 419.20 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) 9,476 MMBtu 12,019 MMBtu
Total 29,364.40 MMBtu 32,060.80 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, 2009 June 30, 2010

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 EMU Climate Action Plan set 2010 as our baseline year for GhG emissions. EMU also was an early adopter of energy efficiency with major upgrades in the early 1980s and then again around 2000.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 629,977 Gross square feet 631,867 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 0.05 MMBtu per square foot
Source energy 0.11 MMBtu per square foot 0.12 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 3,853 Degree-Days (°F)
Cooling degree days 1,161 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 12,776 Square feet
Healthcare space 1,444 Square feet
Other energy intensive space

EUI-adjusted floor area, performance year:
675,807 Gross square feet

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

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):

EMU participated in the 2015 Campus Conservation Nationals competition, placing 3rd overall and were awarded the Grand Prize for the competition from Lucid. The student environmental group Earthkeepers hosts a annual mini-grant for all campus to submit proposals for funding from a $1000 pool and usually students are the main applicants with projects like drying racks in dorms to reduce dyer usage, timers on the tennis court lights and shower timers to reduce hot water use. The three LEED Gold residence halls all have window switches that disable heating and cooling to individual rooms when windows are opened.

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

EMU uses 25Live software to schedule the usage of rooms across campus. That data is migrated to our Siemens Insight scheduler which utilizes setbacks for unoccupied rooms to save energy for heating, cooling and ventilating in non-laboratory/chem storage spaces. EMU also uses occupancy sensors in various residence halls and some academic spaces.

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

The vast majority of indoor lighting and some outdoor lighting has switched to LED lamps, except for a few spaces upgraded to T-5 fluorescent lamps in the last half decade. A performance contract with Siemens this year has led to retrofitting or replacing 5450 lamps in the past three months, finishing up work started in-house by EMU electricians nearly 5 years ago.

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

EMU has switched three residence halls and two academic buildings to high efficiency mini-split heat pumps in the last 8 years, replacing inefficient boilers and hydronic heating systems. When modeled in the three residence halls, the Mitsubishi mini-splits were more efficient at a greatly reduced cost than the geothermal heat pumps originally specified in the drawings. In the years since installation, the Mitsubishi's have been even more efficient than what the modeling concluded.

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):

EMU has been replacing large pumps and fans across campus or upgrading pump with Variable Speed Drive controls, particularly in air handling units and cooling towers.
