Energy Audit

What is an Energy Audit?

IS A TOOL THAT ALLOWS ORGANIZATIONS TO KNOW WHERE THEY STAND WITH RESPECT TO ENERGY USE

An energy audit is a systematic procedure that allows us to understand the actual energy usage in a company (building, group of buildings, industrial facility or operation, or a private or public service), so we can identify and quantify potential savings, and develop a final report with the main improvement proposals at an efficient cost.

At Gloval, we conduct energy audits following the guidelines set by the UNE EN 16247 standard:

  • We start with updated, measured, and verifiable operational data on energy consumption.
  • We conduct a detailed examination of energy consumption.
  • We propose improvement measures based on profitability criteria and cost analysis, adapting to the needs of each client and delving into the aspects that interest you the most.

Who needs an Energy Audit?

MANDATORY FOR ALL LARGE COMPANIES (NOT SMES) EVERY 4 YEARS

According to Spanish Royal Decree 56/2016 of 12 February, that incorporates the Energy Efficiency Directive 2012/27/EU, energy audits are required every 4 years from companies and consolidated corporate groups with over 250 workers or a turnover of over 50 million euros and a balance sheet of over 43 million euros, but not from micro-enterprises and SMEs.

What makes Gloval different?

NETWORK OF QUALIFIED TECHNICIANS AND THE APPROPRIATE TECHNICAL MEANS

Gloval has professionals with adequate technical qualifications for the performance of energy audits at any level, as well as the appropriate technical means to provide energy services in the area of activity in which the company acts, at the time of the specific action.

Our commitment to the environment will lead us to seek the most efficient actions with the least environmental impact.

We adapt to the client, analyzing the technical and economic feasibility of those improvement proposals in which you are interested.

Our experience in Technical Due Diligence, Energy Consulting and Energy Rehabilitation, will allow us to advise you on the most beneficial improvement proposals for your company, as well as the identification of subsidy lines or the monetization of savings through Energy Saving Certificates (CAES).

How do we do an Energy Audit?

WE APPLY TOOLS AND PROCEDURES RECOGNIZED BY THE MINISTRY OF DEVELOPMENT AND FOR THE ECOLOGICAL TRANSITION.

01

Initial meeting

We identify the parties to be involved and the functions to be performed, the scope or limits of the audit and the level of detail.
The level of participation of the building occupant and a visitation forecast are established.

02

Data collection and analysis

We gather the necessary documentation to describe the installations and to know the most relevant energy consumption elements of each installation.
We analyze the data set obtained and evaluate whether it is sufficient to continue the process.

03

Inspection

We inspect the site, collect operational data, and perform the necessary measurements.
We verify the operational and maintenance status of the existing facilities and analyze the feasibility of potential energy efficiency improvement measures.

04

Analysis and conclusions

We prepare a clear and concise report with all the tasks performed and a detailed account of the main recommended measures.
Presentation to the client with an explanation of the obtained results, addressing any questions. This way, the client will be able to make informed decisions regarding both the appropriateness of use and future investments.

What do we analyze and evaluate?

Once the information has been compiled and analyzed, we establish the initial status so that we can have a broad and real knowledge of the building’s consumption, which serves as a basis for studying the possibilities for improvement and we proceed with the analysis and evaluation:

a. We evaluate the role played by the thermal envelope (insulation, windows…).

b. We evaluate the energy consuming systems within the building as a whole (lighting, hot water, air conditioning, ventilation and air renewal, machinery of the activity…).

c. We analyze the billing of the different energy supplies. The energy is broken down both by type of fuel and by service or facility.

as well as by service or installation.

d. We analyze the energy control and management systems.

e. We identify energy improvement proposals based on the experience of the technical writer and taking into account the state of the facilities (age, state of maintenance and operation regime).
We study the possibility of using free resources and renewable energies.

f. We evaluate which proposals are best suited, indicating the technical and economic feasibility.

Frequently Asked Questions

The Energy Saving Certificate (CAE) is an electronic document that guarantees that, after carrying out an energy efficiency action, a new final energy saving equivalent to 1 kWh has been achieved. Thus, if an action is undertaken that implies a new annual saving of 1000 kWh, 1000 CAE can be obtained. This instrument makes it possible to monetize energy savings, recovering part of the cost of investments in energy efficiency, since the end user will be able to receive a consideration if he sells the savings obtained for subsequent certification through the CAE System.
The CAE system is a free market, so there is no fixed price for each CAE obtained, however, 1 CAE could be estimated between 0.08 and 0.12 €. In other words, an annual saving of 1000kWh of final energy could be valued at €1,200.

Aunque no estés obligado, siempre será conveniente realizar una auditoría energética que permita:

  • Mejorar los costes de explotación: averiguar qué elementos o factores influyen en tu consumo de energía te permitirá identificar posibilidades de ahorro.
  • Adaptar el uso de las instalaciones a las necesidades reales existentes, reduciendo el consumo sin perder confort.
  • Evaluar la viabilidad técnica y económica de la implantación de ciertas medidas.
  • La auditoría energética incluye un certificado energético cuyo periodo de validez es de 10 años.
  • Mejorar la imagen de tu empresa, al apostar por la responsabilidad social, el cuidado del medioambiente y una gestión eficiente de los recursos.

De acuerdo al artículo 2 del RD56/2016 solo es obligatorio para las grandes empresas.

Sin embargo, la auditoría energética es una herramienta recomendable en algunos casos, por ejemplo:

  • Como una actuación previa al proceso de rehabilitación, convirtiéndose en la principal herramienta para desarrollar una estrategia energética eficaz en estos procesos.
  • Cuando exista un consumo energético elevado y, por lo tanto, exista la posibilidad de obtener ahorros importantes, tanto a nivel energético como económico.

The Energy Certificate provides information on the energy consumption and CO2 emissions of a specific property/building/home/premises. It is valid for 10 years (5 in the case of G rating).

However, an energy audit comprehensively analyzes the energy performance of the building, taking measures of consumption, proposing improvements and evaluating the cost of these, as well as the return on investment.

Kick-off meetingImplementing the proposed improvement measures is not mandatory, however, it is recommended as they will help to improve operating costs and make the activity more energy efficient.
