ABSTRACT

It is essential for the productivity of companies to take care

of their resources and optimize both environmental and

economic aspects for their long-term profitability; in the

industrial sector of Ecuador, the textile industry has a great

productive impact, which is why this research has

investigated its energy efficiency. The recent update of the

ISO 5001:2018 standard, allows to set the focus on an

energy management system based on continuous

improvement, which allows changing not only business

realities, but also environmental. This work addresses the

analysis of the energy baseline of a textile company, which

indicates that there is no adequate correlation between

energy consumption and production. This study

demonstrates the benefit of implementing an energy

management system based on ISO 50001: 2018.

Keywords: energy efficiency, energy management systems,

energy in the industrial sector, ISO 5001:2018 standard.

INTRODUCTION

The energy crisis constitutes one of the most relevant current problems worldwide, which

is why several researches have been developed around this issue.(Díaz Méndez & Varón

Buenaventura, 2019). The United Nations Organization (UN), in 2015 proposed the

Sustainable Development Goals, whose objective focused on the energy sector and its

sustainability, encouraging the massive consumption of clean energy, in addition to

promoting the social responsibility of people in energy consumption in cities and

communities. (Mendoza et al., 2015). In the productive and economic field within the

industrial field, it has been shown that the implementation of an energy management

system reduces energy billing costs by up to 25%, in a period of time of approximately 1

to 3 years. (Sevilleja Aceituno & Soto Martos, 2011).

This work focuses on the use of an energy management system in accordance with the

ISO 50001 standard, which is based on the continuous improvement of energy

performance. (Buritica Macias et al., 2021). Several companies worldwide have established

its implementation, as is the example of the United States with the Superior Energy

Performance (SEP) program, this program in relation to ISO 50001, use relevant data such

as energy measurements to perform the calculation of energy performance.(Carretero

Peña & García Sanchez, 2015)..

Another example is Chile, which in recent years has transformed its energy consumption

with the introduction of renewable energy sources, becoming the third in South America

in investing in this type of energy in the last 10 years, with an approximate investment of

$14,000. (Pastén, 2012) It is for this reason that it is of great importance to guarantee the

reliability and stability of these systems, considering the energy supply and demand that

depends on renewable natural resources. (Gómez Rodriguez & Chou Rodriguez, 2019)..

In national spheres, the National Energy Balance (BEN), carried out in Ecuador in 2019,

states that the consumption of electric energy per person has increased by 39.4% since

2009, and despite that, one of the main energy sources was also oil.(Ministry of Energy

and Non-Renewable Natural Resources, 2019). The year 2019 statistical data was

obtained that showed that electricity and diesel were the most consumed sources in the

public and commercial sector. (Ludeña & Wilk, 2013)..

The ISO 50001 standard, since its entry into force, has been rapidly implemented in the

production processes of the business sector, however, sometimes this implementation

has been conditioned by difficulties in the energy baseline and its proper

delimitation.(Bravo Hidalgo & Martinez Perez, 2017) This standard has had several

modifications, the last one was made in 2018 and aims to improve energy efficiency, and

energy use and consumption. (International Organization for Standardization, 2018)

Therefore, the ISO 50001:2018 standard focuses on performance improvement, in order

to obtain improvements in its long-term indicators, such as the energy baseline.

(International Organization for Standardization, 2018) In the industrial sector there are a

large number of organizations with high energy consumption, so ISO 50001:2018 is an

ideal option for the implementation of an energy management system, because this

promotes environmental responsibility and improvement of the working environment,

where all levels of the organization are involved, led by senior management because its

implementation involves the acquisition of optimal and adequate equipment and protocols

that use energy for its operation. (Andrade Zambano & Lucia, 2021)(Gamaso López, 2018)

The energy baseline (EBC) is a measurable representation of the ideal consumption. This

energy baseline is calculated using mathematical methods that result in an approximation

of the energy values that should be used to produce certain elements, these calculations

can be performed before and after improvements have been implemented.(Lara Izaguirre

et al., 2019). It can be calculated with the use of both linear and nonlinear regressions,

after the analysis of the straight line, the Pearson correlation coefficient is obtained in an

easier way, which indicates the variation of the two variables that means the energy that

is consumed during production. (Jiménez Jiménez, Diego David; Potes Valencia, 2022)

With this background, this article is based on the implementation of an energy

management system in a textile industry, in compliance with the ISO 50001 standard as

modified in 2018, and analyzes the adequacy of its energy baseline.

MATERIALS AND METHODS

The present study was conducted through literature analysis of research related to

energy management systems based on the ISO 50001 standard of the year 2018 and its

energy efficiency, in addition to the analysis of data from a textile company.

Several types of research were used, including documentary research, which was

necessary to obtain information related to energy efficiency, obtained from various

databases such as Google Scholar, and using keywords for searching, such as: energy

efficiency, energy management systems, energy in the industrial sector, ISO 5001:2018;

the selected articles were examined in their summary to be subsequently selected for

further study. Articles were collected without language distinction and in a publication

period ranging from 10 years old, in addition, implementation guides, and national and

international regulations were obtained.

The field research methodology was used to obtain the invoices of energy consumption

and expenses used in the textile company under investigation; through the analysis of

the invoices and a Fluke 43 type network analyzer, the results regarding electric energy

were identified.

The descriptive research was necessary for the determination of the existing problems

in the electrical condition of the company, which affect the energy efficiency of the

company.

The inductive-deductive method was used to identify the equipment, processes and

tools used by the textile company to determine the respective energy efficiency

indicators, and in turn highlight the aspects that require improvement to reduce energy

consumption at the same level of production.

Based on the synthetic analytical method, the information collected in the initial phase

was integrated with the measurement of the corresponding electrical parameters, in

order to determine the current energy status of the company.

Using the statistical method, the results of the initial analysis of the company's energy

management system and its energy baseline were tabulated, and the non-representative

energies were discriminated with the Pareto diagram.

In order to obtain the company's electrical parameters, the company's facilities were

observed, checking its electrical system, equipment, electrical protections and lighting.

The measurement was another important step to obtain the electrical parameters and

was performed with the Fluke 345 equipment, by means of which important current

unbalances were determined, which require attention and improvement.

The calculation of the low power factor penalty was also performed, as well as the

energy baseline calculated with the energy consumption in relation to production.

RESULTS

In a recount of all the company's consumption over a period of 1 year (July 2021 - July

2022), it was obtained that water consumption is $201.15, equivalent to 5%; electricity

consumption is $2998.91, equivalent to 80% and diesel consumption is 558.33, which

corresponds to 15%. Electric energy is the most representative according to its

consumption, which covers 80% of the total energy consumed and paid in the company.

For this reason, this article focuses on electric energy. It is explained in the following

Pareto diagram.

Energy management system focused on consumption

ISO 5001:2018, seeks in its strategy, that companies improve their energy management

by taking advantage of opportunities based on their characteristics and production

processes. During the design of the energy management system, the different energy

sources that are used and the impact that each of them has on the organization are

analyzed. In this company, electricity has been identified as the main source, so the

management system based on this standard is based on its economic and environmental

impact and benefit.

To obtain this data, a study was made of electricity consumption in relation to

production for the last year, which runs from July 2021 to July 2022. These data were

obtained from monthly invoices and production of historical records. Where it was

determined that in this energy baseline the R2 is 0.72, which explains that there is not

an adequate correlation with the minimum value which is 0.9. The objective of

implementing an energy management system based on ISO 50001:2018 is to improve

energy efficiency and this would be reflected in the energy baseline.

DISCUSSION

The analysis and calculations showed that the most significant consumption in the

company is electrical energy, leading to a future study and implementation of a

management system that implements improvements in energy efficiency. The

quantification of energy consumption in the company allowed determining the energy

baseline that indicates an R

of 0.792, which explains that there is a low correlation when

taking into account the minimum value of R

which is 0.9 to be considered within the

normal range; the reliability of the data is 95%.

It can finally be stated that the improvements in energy consumption are attributable to

the modification of organizational awareness, which integrates and implements an energy

management system aimed at consumption with greater responsibility and control, such

as one based on the ISO 50001:2018 standard, because that is its primary objective.
