"What Gets Measured Gets Managed"
The RCM needs to understand utility bills, rate schedules, and the service provider’s terminology in order to track and analyze consumption data, and guide efficiency efforts. Diligent tracking allows the RCM to promptly identify billing errors or excessive consumption so corrective action can be taken.
Resource accounting typically applies to these resources and services:
- Energy: electricity, natural gas, oil, propane
- Transportation fuels
See Resource Billing Basics for details on how these resources are typically measured and billed. Use the Baseline Data Form to help you record base-year data for each facility and meter. This data is necessary to calculate potential savings and revenues from future efficiency measures.
Know Your Utility and Service Providers
It is important to understand the details of each utility or service program for your facility. Get to know your utility representative and service providers to stay current with efficiency offerings and incentives they may provide.
Carefully study each provider’s billing process, rates, and fee structures to take advantage of discounts. Review the billing history to familiarize yourself with previous expenditures. Billing errors are not uncommon; refunds and immediate savings are the reward for tracking them down.
See Electric Rate Basics to understand how consumption charges, demand charges, and power factor are calculated for electricity.
Know Your Meters
Become familiar with all of the facility’s meters. The Facility Survey Form will help you locate and identify your meters. If your facility has electronic digital meters, your utility may be able to provide daily load profiles, which are useful in understanding how energy is consumed.
Document electricity load profiles to determine the electrical load for each meter. Note initial meter readings, and repeat your readings in 10 to 20 minutes. Collect this information during typical usage patterns and at different times of the year to develop load profiles for each facility.
A key element of an effective RCM program is accurately tracking energy and resource use. The information in this Resource Accounting factsheet will help you get started. Resources to help reduce consumption are listed on Tip Sheets and Tools.
As you monitor resources, be aware of the following factors that can increase consumption costs:
Electricity, Gas, Propane, and Fuel Oil
- Equipment left on when not needed (uncontrolled)
- Energy management control system (EMCS) not programmed to match occupancy patterns
- The EMCS battery, which protects the customer-programmed schedules, has failed and the factory-installed default program is operating
- HVAC system providing100 percent outside air during hot or cold weather conditions
- Incorrect meter reading
- Leaky ducts in HVAC systems
- Incorrect multiplier applied to meter reading
- Engine block heaters operating uncontrolled
- A major leak in the heating distribution lines from steam or hot water boilers
- A leak in the underground tank or lines to the boiler (oil and propane)
- Leaks (domestic use or irrigation)
- Incorrect reading of the water meter
- Plumbing fixtures stuck in the on (or flush) position
- Auto-flush urinals with high-volume flushing
- Illegal or unauthorized dumping into facility Dumpsters
- Service provided for partially filled or empty Dumpsters
- Recyclable items in the garbage
