Creating A Greener Energy Future For the Commonwealth
Current Situation in Massachusetts
• Commonwealth owns and
operates 65 million square
feet of buildings across
hundreds of campuses
• Tracking energy use occurs
inconsistently and only
through utility bills on a
monthly basis
• Where tracking does happen,
sites cannot track down to the
building level as many
buildings do not have their
own utility meters
3
UMass Lowell Campus alone
consists of 2.8 million square
feet, 3 distinct campuses, 46
buildings, 15 electric meters

Community
• Energy spend in the hundreds of millions of dollars annually
• For most properties, unable to identify building energy use and cannot
therefore identify poor energy performers
• Monthly energy data ok for tracking but not for real-time response to
anomalies or operational issues

EEMS Program
DOER elected to target $10 million of federal stimulus
(ARRA) funds toward the development of a state
government wide Enterprise Energy Management System
to meter energy consumption at the building level and
provide real-time energy data to help maximize efficiency
through improved long-term planning and short-term
response.
– Phase 1: Building metering and EEMS application at 410
buildings/17 million square feet of state buildings
– Phase 2: Pending funding, additional 40-50 million
square feet of state buildings

What is EEMS?
1. Installation of over 110
near real-time (5 minute)
building-level meters for
electricity, natural gas,
oil, steam, condensate,
propane, hot and chilled
water
2. Access to web-enabled
software application that
tracks, trends, benchmarks,
and reports on energy
consumption data to drive
energy efficiency

EEMS Benefits
Data from the EEMS is collected in a central software
portal, which will provide:
• Relevant data to state program managers to help target
efficiency funding to buildings and sites that are large
energy users
• Actionable data to individual facility managers, who
can use the data to identify buildings that are
performing poorly and react to real time information
that identifies energy spikes or problems
• Bill auditing resulting in potential reductions and utility
rebates
• Carbon tracking with reporting functionalities
• Threshold settings and alarms to facilities staff

Savings Examples
• EEMS can show high electric demand during morning
which can lead to staggered equipment turn-on, resulting
in lower demand charges
• EEMS can show whether lighting is being turned off at
night/weekends and lead to immediate action
• EEMS can show whether BMS schedules have been overridden for an event and not re-set and lead to
appropriate re-scheduling
• EEMS can highlight which buildings are less/more
efficient and help staff target repairs, building
commissioning, etc.
Anticipate EEMS will result in 5-15%
energy savings

Current Status – October 2011
• Metering
underway at 22
out of 22 large
complexes
• Target Date for
Completion of
Metering
Installation:
November 2011
• Site Surveys for
additional sites
underway
