Theoretical

Service Bill Tracking frameworks are at the focal point of a viable vitality the executives program. Notwithstanding, a few associations invest energy and cash assembling a service charge following framework and never harvest any worth. This paper presents three service charge investigation procedures which vitality directors can use to show up at sound vitality the board choices and accomplish cost reserve funds.

Presentation

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

  • regardless of whether you are sparing vitality or expanding your utilization,
  • which structures are utilizing a lot of vitality,
  • regardless of whether your vitality the board endeavors are succeeding,
  • regardless of whether there are utility charging or metering mistakes, and
  • when utilization or metering abnormalities happen (ie. at the point when use designs change)

Any vitality the executives program is fragmented on the off chance that it doesn’t follow service bills. Similarly, any vitality the executives program is rendered less compelling when its utility following framework is hard to utilize or doesn’t yield significant data. In either case, productive vitality reserve funds openings are lost.

Numerous down to earth vitality administrators settle on the shrewd decision and put resources into service charge following programming, however then neglect to recuperate their underlying interest in vitality reserve funds openings. How could this be?

This paper presents three straightforward and helpful techniques that can be performed with service charge following programming. Simply performing and following up on the initial two kinds of investigation will probably set aside you enough cash to take care of for your utility tab following framework in the primary year. The three points are Benchmarking, Load Factor Analysis, and Weather Normalization as appeared in Table 1.

BENCHMARKING

How about we guess you were the new vitality supervisor accountable for an arrangement of school structures for a locale. Because of an absence of assets, you can’t commit your consideration regarding all the schools simultaneously. You should choose a bunch of schools to redesign. To recognize those schools most needing your consideration, one of the principal things you may do is discover which schools were utilizing an excessive amount of vitality. A basic examination of Total Annual Utility Costs spent would recognize those structures that burn through the most on effort, yet not why.

Benchmarking Different Categories of Buildings

While benchmarking, it is likewise valuable to just think about comparative offices. For instance, in the event that you took a gander at a school area and looked at all structures by $/SQFT, you may find that the innovation communities organization structures were at the highest priority on the rundown, since organization structures and innovation focuses regularly have a greater number of PCs and are more vitality escalated than grade schools and preschools. These outcomes are normal and not really valuable. Thus, it may be insightful to break your structures into classes, and afterward benchmark only each classification in turn.

Distinctive Datasets

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

Sometimes, the board concludes 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 supervisors can utilize benchmarking to direct administration in defining reasonable vitality the executives objectives. For instance, our school region vitality director may choose to make an objective that the three most vitality devouring schools utilize just $0.80/SQFT. Since this is about as much as the most reduced vitality devouring schools are as of now utilizing, this could be an achievable objective.

In the event that you can discover a dataset, you may likewise have the option to benchmark your structures against a lot of comparative structures in your general vicinity and see the scope of opportunities for your structures. Regardless, benchmarking will center your vitality the board endeavors and give sensible objectives to what’s to come.

General guidelines

New vitality supervisors frequently look for a “dependable guideline” to use for benchmarking. A model could be: “In the event that your structure utilizes more than $2/SQFT/Year then you have an issue.” Unfortunately, this won’t work. Various sorts of structures have diverse vitality forces. In addition, diverse structure areas will require varying measures of vitality for warming and cooling. In San Francisco, where temperatures are reliably during the 60s, there is basically no cooling necessity for some, building types; while in Miami, structures will quite often require cooling. Diverse structure types, with their trademark vitality powers, distinctive climate destinations, and distinctive utility rates all join to make it difficult to have dependable guidelines for benchmarking. Be that as it may, vitality directors whose portfolios are for the most part close by, can build up their own general guidelines. These standards will in all probability not be transferable to other vitality chiefs in various areas, with various structure types, or utilizing diverse utility setups.

Benchmarking Buildings in Different Locations

There are a few inconveniences related with benchmarking. Assume you were the vitality director 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 consistently 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 generally costly to work because of high utility rates and distinctive warming and cooling needs.

Some vitality examiners 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 certainly not a reasonable estimation, as it expect that all utilization is related with warming. This estimation additionally doesn’t consider cooling (or warming) needs. Numerous attentive vitality administrators avoid benchmarking that includes CDD or HDD.

Distinctive Benchmarking Units

Another mainstream benchmarking technique is to utilize kBtu/SQFT (every year), as opposed to $/SQFT (every year). By utilizing vitality units as opposed to costs, “general guidelines” can be made that are not discredited with each rate increment. Also, the shifting expenses of various utility rates doesn’t meddle with the correlation.

Benchmarking Summation

Benchmarking is a basic and helpful practice that permits vitality administrators to rapidly evaluate the vitality execution of their structures by essentially looking at them against one another utilizing a family member (and applicable) measuring stick. Structures most needing vitality the board practice are effortlessly singled out. Sensible vitality utilization targets are handily decided for issue structures.

Burden FACTOR ANALYSIS

When you have recognized which structures you need to make increasingly proficient, you can utilize Load Factor Analysis to think your vitality the executives center towards diminishing vitality or decreasing interest.

What Load Factor is

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

What Load Factor Means

High Load Factors (more noteworthy than 0.75) speak to meters that have almost steady loads. Gear is likely not killed around evening time and pinnacle utilization (comparative with off pinnacle use) is low.

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

Burden Factors more noteworthy than 1 are hypothetically unimaginable , however show up once in a while on service bills. Secluded occurrences of extremely high or low Load Factors are typically a marker 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 exceptionally high pinnacle loads or low loads during different hours. Right now, can’t accuse the Load Factor issue for “peaky” cooling loads, as the issue exists all year. A probable reason can be that Tyler MS is making a superior showing with stopping all lighting and other gear around evening time than different schools. One school (Jackson MS) ordinarily has higher Load Factors than different schools. One explanation might be that lighting, HVAC and other hardware is running longer hours than at Tyler MS.

A decent vitality supervisor would examine what building operational conduct is adding to the low Load Factor esteems (and therefore moderately popularity) for Tyler MS, and would research whether the interest could be diminished. Asking about whether Jackson MS is killing hardware around evening time is likewise fitting.

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 on.) will have diverse Load Factor ranges. Since emergency 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 around evening time.
