Utility Bill Auditing: Approximately 50 billing audit calculations are performed to spot possible errors and verify the accuracy of utility billing. Independent Energy Consultants monitors, trends and compares current bills to historical monthly bills to spot discrepancies in parameters such as total cost, total consumption, per unit cost, per unit consumption, peak demands, load factor, length of billing periods, estimated meter readings, overlapping bill periods, etc. User defined limits will flag bill discrepancies in need of further review or correction. Independent Energy Consultants will assist with collection and/or credits for overcharges.
Based on the client's wishes we will either audit your bills after they have been paid, or promptly review them and send your Accounts Payable (A/P) staff notice when bills are correct for payment. Our "smart" energy accounting system can also be linked to your A/P system if desired.
Rate Code Analysis: Your utility company assigns you a rate schedule based on an estimate of how they think you will use electricity or natural gas. Sometimes they guess wrong and often conditions change after a rate schedule is assigned. Your rate schedule determines how much you are billed. Often a facility qualifies to be billed under one of several rate schedules. Independent Energy Consultants will calculate your bill under each acceptable rate schedule and show you which is best for your situation. If electricity savings or natural gas savings are available, we will identify any switching costs and propose a plan that is best for you. Rates and riders change and the energy consumption of most facilities changes over time. We recommend an annual analysis to determine the most appropriate rate code for your unique business.
Tariff analysis: Once a Rate Code analysis is performed to ensure you are being billed under the most advantageous rate we go an extra step to let you know what can be done to minimize your costs under that rate schedule. This analysis looks for excessive demand charges, ratchet demands, power factor penalties, time-of-use pricing, etc.. Once these factors are known, automated or procedural changes can be implemented to avoid operating under high-cost conditions.
Cost Avoidance Verification: Cost avoidance is the name given to the money that was not spent because an Energy Cost Measure (ECM) was performed or installed. It is calculated by comparing a baseline energy consumption before the ECM, to the energy consumption after an ECM, and adjusting for independent variables that influence your usage. The energy not consumed is then multiplied by the current rate to determine the avoided cost. The independent variables that influence a utility bill can vary by season, region, occupancy, hours of operation, product produced, etc.
For clients that contract with 3rd party vendors to implement the ECM, Independent Energy Consultants can provide independent verification that the vendor-installed ECM is operating as specified. Performance Contracting and/or energy loans and grants require this verification. For more information please refer to our newsletter on this topic.

EATR (Exhaust Air Transfer Ratio)
The exhaust air transfer ratio shall be the tracer gas concentration in the leaving supply
air (defined in ASHRAE Standard 84 as Station 2) divided by the tracer gas concentration in
the entering exhaust (return) air (defined in ASHRAE Standard as Station 3) at the rated
airflows, expressed as percentage.
OACF (Outside Air Correction Factor)
The entering supply (outdoor) airflow (defined in ASHRAE Standard 84 as Station 1)
divided by the measured (gross) leaving supply airflow (defined in ASHRAE Standard 84 as
Station 2).
