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):

The baseline was established in 2005 as part of a State Executive Order 145 for energy reduction goals.

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):
---

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

Winter occupied temperatures are controlled between 68 and 70 degrees, unoccupied temperatures are set at 65 degrees. Summer occupied temperatures are controlled between 76 and 78 degrees. Building HVAC systems are controlled on/off based on occupancy schedule for all campus buildings through the campus Energy Management Systems (EMS).


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

LED lights were installed in Parking Lot Q.
Path lights along Cascade Avenue are LED.
Some LED lights were installed in the Ames Suites Residence Hall.
Wyman Education Building 6 bathrooms now have LED lights
LED lights are used in the Sustainability Kiosk in the University Center.
University Center Atrium flood lights are now LED.
University Center kitchen ceiling lights are LED.
University Center convenience store walk-in cooler has LED lights.
Falcon Center parking lot and path lights are LED.
Ag Science 416 - replaced fluorescent lighting with 15 LED 2'x4' fixtures.
Davee Library Stair - replaced fluorescent lighting with 12 LED 2'x4' fixtures with occupancy sensors.
North Hall 220 - replaced fluorescent lighting with 12 LED 2'x4' fixtures with occupancy sensors.
University Center Food Venues - replaced fluorescent lighting with 19 LED 2'x4' fixtures.
Wyman Education Building - replaced fluorescent lighting with 70 LED 2'x2' fixtures and occupancy sensors in corridors. Replaced fluorescent lighting with 11 LED 2'x4' fixtures and occupancy sensors in stairwells.


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

Domestic water heating at the Research Development Institute building and Ames Residential Suites employ passive solar heating.


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

There is one small 30hp co-gen turbine in the Campus Heating Plant.


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):

A new AHU and new distribution duct work was installed to serve the North Hall Auditorium, including new digital controls.

Work done in both the Wyman Education Building and Kleinpell Fine Arts building has been done by in-house staff to fine-tune operations. The campus is also exploring more formal opportunities with Focus on Energy which is a state program that provides incentives.

Regarding energy intensive laboratory space, we have decommissioned 5 fume hoods within the last 3 years in Ag Sci. 214, 220A, 220B, 221A, 221B and added one new unit in 417 Ag Sci.
