10.41 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	18,463,477.41 Kilowatt-hours	62,997.38 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	125,400 MMBtu
Imported steam, hot water, and/or chilled water	45,666.70 MMBtu

Total site energy consumption, baseline year:

234,064.08 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

1,429,317 Gross square feet

Baseline period

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

	Start date	End date
Baseline period	July 1, 2011	June 29, 2012

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

Emerson College has increased its campus square footage by 60% since 2007. While the campus continues to grow and revitalize its spaces, the majority of the current campus began operating in 2010. Thus, the first Sustainability Coordinator set the baseline year to be an average of FY11, FY12, and FY13, to better reflect the general resource use and associated emissions, both per capita and per square foot.

Source energy

Source-site ratio for imported electricity:

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.07 MMBtu per square foot	0.14 MMBtu per square foot
Baseline year	0.16 MMBtu per square foot	0.25 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:

43.31

Optional Fields

Documentation 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:

---

A brief description of energy use standards and controls employed by the institution:

The College recently adjusted set temperatures for campus buildings to be warmer in the summer and cooler in the winter.

We also have operable windows in most office spaces, classrooms, and residence halls.

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

Emerson College has replaced the majority of campus lighting with LED bulbs over the past several years. Remaining spaces without LED lighting are historic performance venues with hand-spun bulbs.

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:

Emerson College's purchased steam is produced through combined heat and power. Vicinity Energy operates the Kendall Cogeneration Station, which provides both energy and steam to Boston and Cambridge.
