Measuring energy performance
at a specific time establishes a baseline and provides the starting
point for setting goals and evaluating future efforts and overall
performance. Baselines should be established for all levels appropriate
to your organization.
The main
steps involve using the date you've collected to:
-
Establish base
year - Establish a base year (weather-normalized) or an
average of several historical years. Use the most complete and
relevant sets of data available.
-
Identify metrics
- Select units of measurements that effectively and appropriately
express energy performance for your organization. (e.g. ENERGY STAR
benchmark score, Btu/square foot, Btu/ product, total energy
cost/square foot).
-
Publish results
- Announce performance baselines to facilities, managers, and other
key stakeholders in your organization.
Suggestions
-
Some voluntary
environmental initiatives have specific baseline years. If your
organization is participating in such an initiative, check to see if
a specific base year has been established.
-
If price is not used as
a normalizing factor, then be sure to use a source energy accounting
method. Otherwise, if your facilities use a combination of fuels,
your baseline data may contain errors.
