Measures
The expense of conducting
business is on the rise as
fuel, electricity, natural gas
and water prices skyrocket.
Barriers to Resource Efficiency
• Decreasing Utility Budgets
• Increasing Utility Costs
• Rate Increases
• Added Load
• Added SQFT
• Lack of information
• Lack of management commitment
• Lack of a Strategic Plan
A pro-active approach to cutting utility costs is
based on:
• A Comprehensive Utility Management Program
• Extensive Utility Monitoring
• Installation of Efficiency Measures

RCM Training
• Staff training is key to achieving the greatest impact
and to realizing predicted cost savings.
• This may entail installing a full time Resource
Conservation Manager (RCM) or working with an
existing one.
Training is provided on the installation and
integration of policies and procedures.
• development of an Energy Action Plan
• creation of an Energy Advisory Committee and
its operations
• adoption of Incentive Programs that includes
awards and a shared savings plan
A Resource Conservation Management (RCM)
program is customized to assist in efficiency
efforts.
• building equipment adjustments
• technical support
• environmental education and
• implementation of utility/energy fundamentals.
Training is delivered through guides and online resources.
Instructional guides and on-site workshops
are part of the training process

Tailored to adult learning
Content is building specific
Peer group learning
Leverage of 1 facilitator to 15 participants
Positive feedback loop with workshop series
Proven results with 20 years of practice
The end result of a successful
RCM program is the creation of
10 to 20% savings of the total
utility budget.
Utility Monitoring
Utility Monitoring
• Accounting involves the detailed tracking of utility use and
demand.
• Accounting systems will involve utility bill analysis software
and interval metering systems.
• Utility bill software requires input of data from utility bills and can
be used to audit utility bill data and monitor monthly use and
demand.
• Accounting services are tailored to clients needs.
What can be impacted
RCM Impact Potential
Utility Accounting
• Easy-to-use utility accounting software that lets our
clients enter a minimum of 24 months of line-item
billing information on each utility account.
• This data forms a baseline for subsequent comparisons of
utility costs and consumption and tells clients how well the
conservation efforts have paid off over time.

Interval Data
• Tool to compare monthly utility bills against actual
real-time metered data. In most situations, utility bill
information shows bulk usage and cost of individual
sites or buildings on a monthly or bimonthly basis.
• Interval data lets clients monitor usage in 15, 30 or
60-minute intervals.

Data Collection
Once the data-gathering and baseline systems have been
set up, clients develop systems for organizing and reporting
information related to building operations and energy consumption.
Efficiency Measures
Efficiency Measures
• Efficiency measures are selected based on a review of
building loads, systems and plant equipment.
• The sequence of review is first: load reduction
measures, second: systems related measures and third:
optimization of heating and cooling plant equipment.
• Efficiency measures are developed to be
comprehensive in nature and to maximize the building
asset value. Considerations include technology,
maintenance, operation and remaining useful life of
building system.
Building Operations Guide
With all the appropriate information gathered and understood,
the Building Operations Guide is a comprehensive document
that outlines the purpose, procedures, and specifications of the
energy/utility consumption of a facility.
BOG Objectives
• To enable the Building Operator to understand the energy
and environmental impacts of their operating decisions.
• To enable specific tasking to be assigned that will support
initiatives in energy and resource management.
• To provide the groundwork for operations and maintenance
(O&M) documentation, leading toward the development of
standards of performance in building operations.
BOG Objectives
•
•
•
•
Use AutoCad for simple layers
Use floor plans and schematics
Apply documentation to building automation computer software
Plan for annual update of all documentation
BOG Workshop Process
• Develop O&M documentation as part of training to build
“ownership”
• Tasking provides adult education learning practice
• Positive feedback loop in workshop gives credit for energy
savings
• Builds team morale and skillsets
Contents of a typical BOG are as follows:
• Building information
• HVAC Systems
• Lighting Systems
• Operations and Production Equipment Use
- Holiday Shutdown
• Building Weatherization
• Emergency Systems
• Energy Management
Vacation Shutdown
• Working closely with the Mechanical Shop, Custodial Department,
Facility Management and Administration, an appropriate Vacation
Shutdown Plan and the correct implementation plan are developed.
• The shutdown plan should focus on capturing maximum and
savings through shutting down of unoccupied facilities and
adjusting down the schedules for minimum use of occupied
situations during the vacation periods.
Retrofit Plans
• Selecting the appropriate solutions for retrofits
(selecting an esco or design build approach) is part of this service.
• Any retrofit, however small – the change–out of a light bulb, for
example – that has a positive impact on utility consumption, can
easily be tracked for its contribution to the cumulative efficiency
gain.
