Three Powerful Utility Bill Analysis Methods For the Energy Manager

ABSTRACT
Utility Invoice Monitoring programs are on the heart of an efficient power administration program. Nonetheless, some organizations spend money and time placing collectively a utility invoice monitoring system and by no means reap any worth. This paper presents three utility invoice evaluation methods which power managers can use to reach at sound power administration selections and obtain price financial savings.

INTRODUCTION
Utility invoice monitoring and evaluation is on the heart of rigorous power administration follow. Dependable power administration selections could be made based mostly upon evaluation from an efficient utility invoice monitoring system. Out of your utility payments you’ll be able to decide:

– whether or not you might be saving power or rising your consumption,
– which buildings are utilizing an excessive amount of power,
– whether or not your power administration efforts are succeeding,
– whether or not there are utility billing or metering errors, and
– when utilization or metering anomalies happen (ie. when utilization patterns change)

Any power administration program is incomplete if it doesn’t monitor utility payments. Equally, any power administration program is rendered much less efficient when its utility monitoring system is tough to make use of or doesn’t yield invaluable info. In both case, fruitful power financial savings alternatives are misplaced.

Many sensible power managers make the sensible alternative and put money into utility invoice monitoring software program, however then fail to get well their preliminary funding in power financial savings alternatives. How might this be?

This paper introduces three easy and helpful procedures that may be carried out with utility invoice monitoring software program. Simply performing and performing upon the primary two varieties of evaluation will seemingly prevent sufficient cash to pay on your utility invoice monitoring system within the first 12 months. The three matters are Benchmarking, Load Issue Evaluation, and Climate Normalization as proven in Desk 1.

BENCHMARKING
Let’s suppose you had been the brand new power supervisor in command of a portfolio of faculty buildings for a district. As a result of an absence of assets, you can not dedicate your consideration to all the faculties on the similar time. It’s essential to choose a handful of colleges to overtake. To establish these faculties most in want of your consideration, one of many first stuff you would possibly do is locate out which faculties had been utilizing an excessive amount of power. A easy comparability of Complete Annual Utility Prices spent would establish these buildings that spend probably the most on power, however not why.

Benchmarking Totally different Classes of Buildings
When benchmarking, it’s also helpful to solely evaluate related amenities. For instance, in case you checked out a faculty district and in contrast all buildings by $/SQFT, you would possibly discover that the know-how facilities administration buildings had been on the prime of the record, since administration buildings and know-how facilities usually have extra computer systems and are extra power intensive than elementary faculties and preschools. These outcomes are anticipated and never essentially helpful. For that reason, it may be sensible to interrupt your buildings into classes, after which benchmark only one class at a time.

Totally different Datasets
You’ll be able to benchmark your buildings in opposition to one another (as we did in our instance) or in opposition to publicly accessible databases of comparable buildings in your space. Power Star’s Portfolio Supervisor lets you evaluate your buildings in opposition to others in your area. Maybe these buildings in your portfolios that seemed probably the most wasteful are nonetheless within the prime 50th percentile of all related buildings in your space. This is able to be helpful to know.

Often, administration decides that their group wants to avoid wasting arbitrary share (5%, 10%, and so forth.) on utility prices annually. Relying upon the objective, this may be fairly difficult, if not unattainable. Power managers can use benchmarking to information administration in setting sensible power administration targets. For instance, our faculty district power supervisor would possibly resolve to create a objective that the three most power consuming faculties use solely $zero.80/SQFT. Since that is about as a lot because the lowest power consuming faculties are presently utilizing, this may very well be an attainable objective.

If you will discover a dataset, you might also be capable to benchmark your buildings in opposition to a set of comparable buildings in your space and see the vary of prospects on your buildings. In any case, benchmarking will focus your power administration efforts and supply sensible targets for the long run.

Guidelines of Thumb
New power managers usually seek for a “rule of thumb” to make use of for benchmarking. An instance may very well be: “In case your constructing makes use of greater than $2/SQFT/Yr then you will have an issue.” Sadly, this would possibly not work. Various kinds of buildings have completely different power intensities. Furthermore, completely different constructing areas would require differing quantities of power for heating and cooling. In HVAC San Diego, the place temperatures are persistently within the 60s, there may be virtually no cooling requirement for a lot of constructing varieties; whereas in Miami, buildings will virtually at all times require cooling. Totally different constructing varieties, with their attribute power intensities, completely different climate websites, and completely different utility charges all mix to make it arduous to have guidelines of thumb for benchmarking. Nonetheless, power managers whose portfolios are all shut by, can develop their very own guidelines of thumb. These guidelines will probably not be transferable to different power managers in numerous areas, with completely different constructing varieties, or utilizing completely different utility configurations.
