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

Figures needed to determine total building energy consumption:
Performance Year Baseline Year
Grid-purchased electricity 158,480 MMBtu 137,275 MMBtu
Electricity from on-site renewables 80 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) 144,373 MMBtu 134,955 MMBtu
Total 302,933 MMBtu 272,230 MMBtu

Start and end dates of the performance year and baseline year (or 3-year periods):
Start Date End Date
Performance Year Jan. 1, 2017 Dec. 31, 2017
Baseline Year Jan. 1, 2007 Dec. 31, 2007

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):

Gross floor area of building space:
Performance Year Baseline Year
Gross floor area of building space 1,827,238 Gross square feet 1,478,000 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 0.17 MMBtu per square foot 0.18 MMBtu per square foot
Source energy 0.35 MMBtu per square foot 0.38 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 3,996 Degree-Days (°F)
Cooling degree days 1,429 Degree-Days (°F)

Floor area of energy intensive space, performance year:
Floor Area
Laboratory space 25,000 Square feet
Healthcare space 2,500 Square feet
Other energy intensive space

EUI-adjusted floor area, performance year:
1,901,238 Gross square feet

Building energy consumption (site energy) per unit of EUI-adjusted floor area per degree day, performance year:
29.37 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):

The Dir. of Admin. Sustainability works with the design and operations departments in Facilities and with student groups including SGA and Envirolutuion to promote energy efficiency.
In conjunction with the Office of Residential Life and the CSDS we have run lights out programs and events. In addition, I have hired students to turn off window acs in the evenings.

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

Pratt attempts to control interior temps in winter from 68 to 72 and in summer, 76 and above.
Many of our control systems are either very old or non-existent - some steam systems.
We are working on a Roadmap Plan for Energy, GHG and Infrastructure to meet 50 X 40 and 80 X 50.
We are installing vacancy sensors in new projects and working with Con Ed on a LED lighting and controls program.

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

We are installing LED lighting in every new and renovation project.
We are working on a Plan to convert about 90% of all lighting to LED over a period of approximately 3 years.

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

We are currently evaluating the potential for geothermal as part of the Campus Roadmap project described above and we are performing life cycle costs analysis of geo for a new School of Art building of about 100,000 sf.

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

The Campus Energy, GHG and Infrastructure Roadmap is looking at the potential for CHP in our central plant and outlying buildings.

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 using Energy Star products where they are available and are looking at replacement options for HVAC equipment with high efficiency heat pumps vis the Roadmap study.
