Factors affecting savings performance
Valuating savings uncertainty
Minimum operating conditions
Energy prices/tariff rates
Verification by A third party
Baseline modification/review(non-routine)
Balancing uncertainty and costs
Protection from risks by both parties

Options For
Energy Baseline & Saving Calculation
Method Advantages Disadvantages
Utility billing history Low cost •Effects of weather ,
occupancy, other
changes may mask
savings
•May be unreliable
unless savings are
significant compared to
normal bill variation
Data already available
Independent data
Represent all effects of
ESMs
Account for interactive
effects
System/Equipment
sub-metering
Isolate effects of ESMs
•Higher cost
•Misses interactive
effects
Very accurate for

Results are more
predictable(low risk)

Modifying/Reviewing Baseline
To establish standards for “Materials” changes which may reasonable expected to change energy consumption trend in the facility Occupied square footage, operating hours
Facility’s energy equipment/operating parameters other than the ESCO equipment
Energy equipment, other than ESCO equipment, that malfunctions, or is repaired, or replaced in a manner that increases or decreases energy consumption;
Other actions taken by the facility owner that may reduce or increase energy use; and,
Discovery of an error in the original baseline, in which case the change would be retroactive
Trust , good
relationship &
effective
communication
between ESCO &
building owner is
crucial to identify the
needs to
modify/review
baseline!

THE WAY FORWARD
Capacity building for ESCOs and building operators to enhance competencies in energy saving projects implementation
Incentives/rewards/recognition for buildings which produced significant energy savings To create motivation
Supports from banks with independent technical assessment from a competent agency for EPC project proposals for funding To increase numbers & sizes of participation by ESCO & building
owners
One-stop & competent agency for EPC project proposals evaluation & performance measurement & verification
Fiscal incentives for ESCOs & Business friendly procedures
