At ISTC computers are required to be at least EPEAT Bronze rated.
There is mention of EPEAT Bronze in the legislation at the State level—see http://www.ilga.gov/legislation/ilcs/fulltext.asp?DocName=041501500K65. Note that the phrasing in this is a little odd because some of the products mentioned (e.g. mice, VCRs, etc. ) aren’t part of the EPEAT registry. But since a wide variety of people (i.e. people who are not campus procurement personnel) may purchase equipment, office supplies, etc., and not be aware of what EPEAT is, let alone that the state has expectations related to it, it’s perfectly possible that there are researchers or IT professionals who are buying items for University use with little thought about EPEAT.
Procurement would have to confirm whether or not non-EPEAT related computers, laptops or tablets were available from vendors in UI punchouts in iBuy.
