75.32 Btu / GSM / Degree-Day (°C)

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	5,852,287 Kilowatt-hours	19,968 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	18,488.81 MMBtu
Imported steam, hot water, and/or chilled water	0 MMBtu

Total site energy consumption, baseline year:

49,968 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:

46,946.77 Gross square meters

Baseline period

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

	Start date	End date
Baseline period	July 1, 2018	June 30, 2019

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

The above listed year was the College's first year of AASHE reporting. The baseline was set from a collection of data pertinent to that reporting.

Source energy

Source-site ratio for imported electricity:

Total energy consumption per unit of floor area:

	Site energy	Source energy
Performance year	0.98 MMBtu per square meter	1.43 MMBtu per square meter
Baseline year	1.06 MMBtu per square meter	1.92 MMBtu per square meter

Metric used in scoring for Part 2

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

25.26

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:

We have all of our building analytics on a web-based platform that automatically calculate this information.

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

We use both Siemens and Structureware for building management systems. All new construction is brought up to State of Vermont Energy codes.

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

All exterior pole lights on campus are LED retrofitted. We have five buildings that are all LED. Whenever we procure new light fixtures, we ensure that they are LED.

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

We have a geothermal heating and cooling system for our newest building, CAPA, which is also all LED.

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

We have no co-generation on site.

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

Whenever we purchase new equipment, we make sure it is all energy star or the like.

Data source(s) and notes about the submission:

There is no steam coming onto campus or chilled water.We should be getting credits for this, as we have added square footage, removed fossil Fuel burning equipment, so our electrical use has gone up, but emissions have gone down.
