Three Powerful Utility Bill Analysis Methods For the Energy Manager


Service Bill Tracking frameworks are at the focal point of a successful vitality the executives program. Be that as it may, a few associations invest energy and cash assembling a service charge following framework and never procure any esteem. This paper presents three service charge investigation procedures which vitality directors can use to touch base at sound vitality the board choices and accomplish cost reserve funds.


Service charge following and examination is at the focal point of thorough vitality the board practice. Dependable vitality the board choices can be made dependent on examination from a powerful service charge following framework. From your service charges you can decide:

  • whether you are sparing vitality or expanding your utilization,
  • which structures are utilizing an excessive amount of vitality,
  • whether your vitality the executives endeavors are succeeding,
  • whether there are utility charging or metering blunders, and
  • when use or metering inconsistencies happen (ie. at the point when utilization designs change)

Any vitality the board program is fragmented in the event that it doesn’t follow service bills. Similarly, any vitality the executives program is rendered less powerful when its utility following framework is hard to utilize or does not yield significant data. In either case, productive vitality investment funds openings are lost.

Numerous handy vitality chiefs settle on the brilliant decision and put resources into service charge following programming, yet then neglect to recuperate their underlying interest in vitality investment funds openings. How could this be?

This paper presents three basic and helpful strategies that can be performed with service charge following programming. Simply performing and following up on the initial two sorts of investigation will probably spare you enough cash to pay for your service charge following framework in the main year. The three subjects are Benchmarking, Load Factor Analysis, and Weather Normalization as appeared Table 1.


How about we guess you were the new vitality administrator accountable for an arrangement of school structures for a region. Because of an absence of assets, you can’t commit your thoughtfulness regarding every one of the schools in the meantime. You should choose a bunch of schools to update. To recognize those schools most needing your consideration, one of the main things you may do is discover which schools were utilizing a lot of vitality. A basic correlation of Total Annual Utility Costs spent would distinguish those structures that spend the most on vitality, yet not why.

Benchmarking Different Categories of Buildings

While benchmarking, it is likewise valuable to just think about comparable offices. For instance, on the off chance that you took a gander at a school region and thought about all structures by $/SQFT, you may find that the innovation focuses organization structures were at the highest priority on the rundown, since organization structures and innovation focuses regularly have a bigger number of PCs and are more vitality escalated than primary schools and preschools. These outcomes are normal and not really helpful. Hence, it may be insightful to break your structures into classes, and after that benchmark only one classification at once.

Distinctive Datasets

You can benchmark your structures against one another (as we did in our model) or against openly accessible databases of comparable structures in your general vicinity. Vitality Star’s Portfolio Manager enables you to look at your structures against others in your area. Maybe those structures in your portfolios that looked the most inefficient are still in the top 50th percentile of every single comparable structure in your general vicinity. This would be helpful to know.

Every so often, the executives chooses that their association needs to spare some discretionary rate (5%, 10%, and so forth.) on utility costs every year. Contingent on the objective, this can be very testing, if certainly feasible. Vitality directors can utilize benchmarking to control the executives in defining reasonable vitality the board objectives. For instance, our school area vitality administrator may choose to make an objective that the three most vitality expending schools utilize just $0.80/SQFT. Since this is about as much as the most reduced vitality expending schools are presently utilizing, this could be an achievable objective.

On the off chance that you can discover a dataset, you may likewise have the capacity to benchmark your structures against a lot of comparable structures in your general vicinity and see the scope of potential outcomes for your structures. Regardless, benchmarking will center your vitality the board endeavors and give reasonable objectives to what’s to come.

General guidelines

New vitality supervisors frequently scan for a “dependable guideline” to use for benchmarking. A precedent could be: “In the event that your structure utilizes more than $2/SQFT/Year then you have an issue.” Unfortunately, this won’t work. Distinctive kinds of structures have diverse vitality forces. Additionally, extraordinary structure areas will require varying measures of vitality for warming and cooling. In San Francisco, where temperatures are reliably during the 60s, there is no cooling prerequisite for some, building types; while in Miami, structures will quite often require cooling. Distinctive structure types, with their trademark vitality powers, diverse climate locales, and distinctive utility rates all consolidate to make it difficult to have general guidelines for benchmarking. Notwithstanding, vitality chiefs whose portfolios are largely close by, can build up their own dependable guidelines. These guidelines will in all probability not be transferable to other vitality administrators in various areas, with various structure types, or utilizing diverse utility designs.

Benchmarking Buildings in Different Locations

There are a few entanglements related with benchmarking. Assume you were the vitality chief of a chain store, and you had structures in various national areas. At that point benchmarking probably won’t be helpful in a similar sense. Would it be reasonable for contrast a San Diego store with a Chicago store, when it is dependably the correct temperature outside in San Diego, and in every case excessively hot or excessively cold in Chicago? The Chicago store will continually be warming or cooling, while the San Diego store probably won’t have many warming or cooling needs. Looking at $/SQFT may help choose which store areas are most costly to work because of high utility rates and diverse warming and cooling needs.

Some vitality investigators benchmark utilizing kBtu/SQFT to expel the impact of utility rates (supplanting $ with kBtu). Some will make it a stride further utilizing kBtu/SQFT/HDD to evacuate the impact of climate (including HDD), however including HDD (or CDD) is definitely not a reasonable estimation, as it expect that all use is related with warming. This estimation additionally does not consider cooling (or warming) needs. Numerous keen vitality directors modest far from benchmarking that includes CDD or HDD.

Distinctive Benchmarking Units

Another famous benchmarking strategy is to utilize kBtu/SQFT (every year), instead of $/SQFT (every year). By utilizing vitality units as opposed to costs, “dependable guidelines” can be made that are not discredited with each rate increment. Also, the changing expenses of various utility rates does not meddle with the correlation.

Benchmarking Summation

Benchmarking is a basic and helpful practice that enables vitality chiefs to rapidly evaluate the vitality execution of their structures by basically contrasting them against one another utilizing a relative (and pertinent) measuring stick. Structures most needing vitality the executives practice are effectively singled out. Sensible vitality utilization targets are effectively decided for issue structures.


When you have recognized which structures you need to make progressively proficient, you can utilize Load Factor Analysis to think your vitality the board center towards decreasing vitality or lessening request.

What Load Factor is

Burden Factor is normally determined by charging period, and is the proportion between normal interest and top (or metered) request. Normal interest is the normal hourly draw amid the charging time frame.

What Load Factor Means

High Load Factors (more prominent than 0.75) speak to meters that have about steady loads. Hardware is likely not killed around evening time and pinnacle use (in respect to off pinnacle use) is low.

Low Load Factors (under 0.25) have a place with meters that have high pinnacle control attracts in respect to the rest of the example. These meters could be related with chillers or electric warming hardware that is killed for a significant part of the day. Low Load Factors can likewise be related with structures that shut off almost all gear amid non-running hours, for example, primary schools.

Burden Factors more noteworthy than 1 are hypothetically inconceivable , however show up sometimes on service bills. Disengaged examples of high or low Load Factors are typically a pointer of metering blunders.

One school, Tyler MS, reliably has a much lower Load Factor than the others (drifting reliably around 20%). Low Load Factors can be attributed to either high pinnacle loads or exceptionally low loads amid different hours. For this situation, we can’t accuse the Load Factor issue for “peaky” cooling loads, as the issue exists all year. A reasonable reason can be that Tyler MS is completing a superior employment at closing off all lighting and other gear during the evening than different schools. One school (Jackson MS) normally has higher Load Factors than different schools. One reason might be that lighting, HVAC and other gear is running longer hours than at Tyler MS.

A decent vitality director would explore what building operational conduct is adding to the low Load Factor esteems (and therefore moderately intense interest) for Tyler MS, and would examine whether the interest could be diminished. Asking about whether Jackson MS is killing gear around evening time is additionally prudent.

Burden Factor Rules of Thumb

Burden Factor investigation is a craftsmanship, not a science. Diverse structure types (for example schools, workplaces, medical clinics, and so forth.) will have diverse Load Factor ranges. Since medical clinics run numerous territories 24 hours per day, one may expect higher Load Factors than for schools, which can kill for all intents and purposes everything during the evening.
