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 15,299,000 Kilowatt-hours 52,200.19 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 110,118 MMBtu
Imported steam, hot water, and/or chilled water 0 MMBtu

Total site energy consumption, baseline year:
162,318.19 MMBtu

Baseline year building space

Gross floor area of building space, baseline year:
1,145,166 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, 2004 June 30, 2005

A brief description of when and why the energy consumption baseline was adopted:
Our baseline year is the 2005 fiscal year (2004/07/01 - 2005/06/30), which is when Evergreen's first detailed emissions inventory was performed.

Source energy

Source-site ratio for imported electricity:
3

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.07 MMBtu per square foot 0.12 MMBtu per square foot
Baseline year 0.14 MMBtu per square foot 0.23 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:
48.92

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:
There are signs scattered throughout campus buildings reminding people to turn out lights before they leave a room. In the Seminar II building, which was constructed with a specific energy-efficient design, there is additional signage in some rooms and offices with guidance on opening/shutting doors and windows to avoid wasted heating/cooling.

A brief description of energy use standards and controls employed by the institution:
Evergreen uses a district steam system for campus heating. Steam pressure has been reduced and building warm-up times have been moved closer to the start of each day and customized, in conjunction with space scheduling, to end prior to the end of occupancy time in each building.

Most rooms in campus buildings, in particular restrooms, employ automated light switches through motion-sensors.

A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
Evergreen has worked to replace incandescent lighting in its apartments and residence halls with LEDs and Compact Fluorescent Lighting (CFL) bulbs. It has also replaced T12 ballasts with T8 ballasts, which has brought a 30 percent energy-use reduction by itself.

A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Evergreen employs passive cooling in the Seminar II and College Activities (CAB) buildings, both of which have been awarded LEED Gold designation. Passive cooling in these buildings is achieved through overall building design and large, exterior-opening windows. Evergreen also utilizes white or light-colored roofing on many of its buildings to reduce albedo and minimize summer heat gains.

A brief description of co-generation employed by the institution:
Evergreen does not employ co-generation.

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Evergreen has conducted a large-scale energy efficiency renovation of its Lab I building and is currently in the process of renovating the Lab II and Seminar I buildings. These renovations are intended to improve the overall energy efficiency of each buildings, especially as it relates to heating and cooling.
