UC Los Angeles Campus & Medical Center Strategic Energy Plan ...

future VM projects. The number of "virtualizable servers" per campus was estimated using data
provided by the UC Berkeley IT Department and then prorated by the number of enrolled
students per campus in Fall 2006. This includes both the decentralized servers across campus
and servers that are in the data center servers. A ratio of ten baseline servers consolidated
onto one virtual machine was used based on a conservative estimate from past partnership
projects.
Note that this project is based on the reduction in the number of servers operating and their
local air conditioning load. Where a large air handler was operating continuously to cool a
server, this measure was included in the HVAC projects.
8.6.4 Campus Wide Project 4. Network Computer Power Management Software/CRT
Network computer power management software is recommended to power down computers
that are on the network when they are not being used. Network PC power management
software energy savings potential was calculated based on deemed values provided by the
Verdiem PG&E work paper. Installed cost was estimated by the retail price of the software with
installation, and with additional maintenance and support costs. For each campus, the number
of computers on campus was estimated based on data provided by UC Berkeley's BETS
database and prorated by the number of enrolled students per campus in Fall 2006. The BETS
database showed the number of computers on campus older than 5 years. To be conservative,
we estimated that half of these computers represented the number of managed, networkedcomputers
on which power management software could be installed. However, we recommend
that power management software be installed on all managed, networked-computers.
CRT monitor to LCD monitor conversions were also recommended for each campus. Both the
energy savings potential and cost were based on the Energy Star calculator for LCDs, adapted
to represent conventional 17" CRT monitors to be replaced by Energy Star 17" LCDs. We
recommend, however, that all CRTs be replaced with Energy Star LCDs to maximize energy
savings.
8.6.5 Campus Wide Project 5. Install Controllers on Vending Machines
Vending machines and sliding-door coolers can easily be retrofit to use approximately 40
percent less energy using inexpensive controllers. To examine the potential for this efficiency
measure, counts of sliding door coolers and two types of vending machines, refrigerated and
non-refrigerated, were collected from the UC campuses. Information about existing measures to
reduce the energy consumption of these machines (e.g. requiring service providers to use
Energy Star machines) was also gathered to avoid duplication of those efforts. For campuses
that were not able to provide vending machine data, typical values determined for the rest of the
UC system were applied.
Based on the reported or estimated number of vending machines on each campus and the
estimated annual energy usage of a machine, the existing energy consumption of all vending
machines was calculated for each campus. For campuses that had not implemented controls or
had done so only to a limited extent, full use of controllers on all campus vending machines and
sliding-door coolers is recommended. The energy and cost savings associated with
implementing this measure are calculated based on typical energy savings listed in the
Database for Energy Efficient Resources (2005) and reported by equipment manufacturers.
