13.51 Btu / GSF / Degree-Day (°F)

Part 2. Reduction in source energy use per unit of floor area

Baseline year energy consumption

STARS 2.2 requires electricity data in kilowatt-hours (kWh). If a baseline has already been established in a previous version of STARS and the institution wishes to continue using it, the electricity data must be re-entered in kWh. To convert existing electricity figures from MMBtu to kWh, simply multiply by 293.07107 MMBtu/kWh.

Electricity use, baseline year (report kWh):

	kWh	MMBtu
Imported electricity	14,380,326 Kilowatt-hours	49,065.67 MMBtu
Electricity from on-site, non-combustion facilities/devices (e.g., renewable energy systems)	0 Kilowatt-hours	0 MMBtu

Stationary fuels and thermal energy, baseline year (report MMBtu):

	MMBtu
Stationary fuels used on-site to generate electricity and/or thermal energy	134,955 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

184,020.67 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

1,478,000 Gross square feet

Baseline period

Start and end dates of the baseline year (or 3-year period):

	Start date	End date
Baseline period	Jan. 1, 2007	Dec. 31, 2007

A brief description of when and why the energy consumption baseline was adopted:

2007 chosen in conjunction with NY Office of Climate Change.

Source energy

Source-site ratio for imported electricity:

3.14

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.08 MMBtu per square foot	0.13 MMBtu per square foot
Baseline year	0.12 MMBtu per square foot	0.20 MMBtu per square foot

Metric used in scoring for Part 2

Percentage reduction in total source energy consumption per unit of floor area from baseline:

31.44

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

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:

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.
We have engaged an engineer to evaluate electrification most likely using geo.

A brief description of co-generation employed by the institution:

The Campus Energy, GHG and Infrastructure Roadmap is looking at the potential for CHP in our central plant and outlying buildings.
We are redesigning the central palnt to improve efficiency by 10-20%.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:

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.
