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

Energy consumption baseline was taken from FYs 2009-2011. These years were chosen to give us a solid history representative of average use.

A brief description of any building temperature standards employed by the institution:

A building temperature policy was adopted in May of 2009 to conserve energy and make best use of our resources.


A brief description of any light emitting diode (LED) lighting employed by the institution:

LEDs have been installed in part in most of our major buildings on campus, mostly to replace incandescents. Some LED stick lighting has been used in major hallways of buildings as a pilot to better understand costs and savings. LEDs have replaced HIDs in our parking structures and are now piloted on exterior sidewalks to hopefully replace HIDs there as well.

A brief description of any occupancy and/or vacancy sensors employed by the institution:

Occupancy sensors have been installed in all new construction and major renovations the last five years or so. In other buildings, as lighting retrofits have been undertaken, occupancy sensors have be installed there as well.

A brief description of any passive solar heating employed by the institution:


A brief description of any ground-source heat pumps employed by the institution:


A brief description of any cogeneration technologies employed by the institution:


A brief description of any building recommissioning or retrofit program employed by the institution:

A brief description of any energy metering and management systems employed by the institution:

Energy metering (electricity, gas, Chilled Water & steam) was installed in all major buildings to help monitor our energy use. Unfortunately many of these early meters failed. They are currently being replaced and will provide valuable granular energy use information for all major buildings.

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

This is an on-going effort, driven by facilities management & planning and encouraged by purchasing. http://www.unomaha.edu/green/purchasing1.php

A brief description of any energy-efficient landscape design initiatives employed by the institution:

All bluegrass has been replaced with drought-tolerant fescue, removed in favor of xeriscaping or native tall grasses, or has at least had its associated irrigation largely reduced.

A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:

Vending machines have been slowly replaced by ones with motion sensors, lightless models or LED-lit machines. This was largely done because other users demanded it and vendors made large-scale changes in machine selection.

A brief description of other energy conservation and efficiency initiatives employed by the institution:
