Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 238,621 MMBtu 196,821 MMBtu
Electricity from on-site renewables 2,856 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) 544,075 MMBtu 352,997 MMBtu
Total 785,552 MMBtu 549,818 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):

Binghamton University started implementing a "green revolving fund" program in 2006 to improve energy efficiency and increase campus recycling and composting rates. FY 2004-2005 was selected as the baseline to gauge our progress since the inception of our most tangible sustainability program.

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 6,653,640 Gross Square Feet 4,966,342 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 0.12 MMBtu / GSF 0.11 MMBtu / GSF
Source energy 0.19 MMBtu / GSF 0.20 MMBtu / GSF

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 7,984 Degree-Days (°F)
Cooling degree days 356 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 641,235 Square Feet
Healthcare space 21,000 Square Feet
Other energy intensive space

EUI-adjusted floor area, performance year:
8,254,215 Gross Square Feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
11.41 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):

Our centralized energy management system controls building cooling / heating and lighting based on occupancy schedule. During unoccupied winter period, building temperatures are set back to 50F. During summer unoccupied period, cooling and lighting will be turned off.

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

LEDs have become the technology of our choice for outdoor lighting, new construction, and major building renovation projects. Nearly 100% of our outdoor fixtures have been replaced with LEDs. The new buildings and major renovation projects completed after 2014 are all equipped with all LED lights. Binghamton University has adopted LED lighting as our new design standard.

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

The Engineering & Science building has a damper controlled air passage way to the inlet of the air handling units. Air is preheated through the darken tinted solar glass wall when needed. When air preheating is not necessary, the air intake bypasses the glass wall.

A brief description of co-generation employed by the institution, e.g. combined heat and power (CHP):

Not at this time.

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):

Binghamton University has a dedicated group of staff that continuously monitors the building energy performance using a centralized building energy management system. Critical control parameters such as temperature, pressure, and flow are checked against design data. Corrections and optimization are made as appropriate.
