A brief description of when and why the building energy consumption baseline was adopted:
The baseline was established in 2005 as part of a State Executive Order 145 for energy reduction goals.
A brief description of any building temperature standards employed by the institution:
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 any light emitting diode (LED) lighting 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 any occupancy and/or vacancy sensors employed by the institution:
Occupancy sensors are used to control lights in parts of all campus buildings, including classrooms, labs, and bathrooms. Daylight sensors added in Wyman Education Building Computer Lab in 2015.
A brief description of any passive solar heating 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 any ground-source heat pumps employed by the institution:
A brief description of any cogeneration technologies employed by the institution:
There is one small 30hp co-gen turbine in the Campus Heating Plant.
A brief description of any building recommissioning or retrofit program employed by the institution:
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.
A brief description of any energy metering and management systems employed by the institution:
Johnson Controls' MetaSys is used to monitor energy consumption and performance across campus from the Central Heating and Cooling Plant. Steam, electricity and water are all metered at each building.
The campus in 2016 is also hoping to develop in-house a Real-Time energy reporting tool for all of campus that reports out in an easy to use format, energy information directly from MetaSys.
All campus buildings have steam (condensate) and electrical sub meters that are read monthly and compared to the previous four years.
A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:
We purchase energy star rated appliances for all new and replacement equipment.
A brief description of any energy-efficient landscape design initiatives employed by the institution:
The Ames Suites project includes an area of native grass that is not mowed. Drip irrigation is used for vegetation around the University Center building. Preservation areas along the South Fork stream that runs through campus preserve a relatively large area of native vegetation and incorporate natural (unpaved) trails.
A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:
As of 2009 academic year, all vending machines on campus that do not contain perishable items are using "Vending Misers"
A brief description of other energy conservation and efficiency initiatives employed by the institution:
An Institutional funded, energy conservation project program was established for FY 2014 with a budget of $100,000. Projects completed with these funds include the following:
Energy efficient hand dryer replacement.
Replacement of inefficient A/C unit for Postal/Stores.
Heating Plant Boiler Tune-up.
DDC upgrades for Grimm & McMillan energy meters.
Reverse Osmosis unit to replace steam water still.
Various Lighting upgrade projects including South Hall, Davee Library and Wyman Education Building.
Controls at the room level were replaced at the University Center to allow occupied/unoccupied scheduling of individual meeting rooms. See a listing of efforts here:
2015 - North Hall was connected to the campus chilled water system for building cooling, allowing the removal of an inefficient, 40 year old DX system.
New energy efficient, exterior windows were installed in the Kleinpell Fine Arts Building.
New high efficient natural gas water heater was installed in Crabtree Residence Hall, allowing steam to be shut off to the east end of campus for an extended period of time over the summer.
The website URL where information about the institution’s energy conservation and efficiency initiatives is available:
"Other energy intensive space" includes the Greenhouse at 12,262 GSF.
Energy intensive laboratory space includes computer labs: 11,675 sq ft and science labs with more than one fume hood: 7,192 sq ft.

We indicated the ratios that EPA uses, even though we do not use electricity to heat our buildings nor do we purchase steam from a district provider. -Tim Thum, Re: source-site ratios
The reason for reporting 1.9M here versus IC 2 where we noted 2.2M is that the 2.2M includes the two campus farms also of which we don't have energy consumption information. The 1.9M for this section, we do have reliable data.
