Climaval Eficiencia energética

Climaval loyal to its thematic policy celebrates the IV Edition: Circular Economy and Energy Solutions

/in , ,

Avaesen remains loyal to its organizing events policy to promote the sustainability activities, energy efficiency and reduction of CO2 emissions. In the last edition, the theme focused on the hotel sector, this year will focus on the industrial sector, also in need of new ideas, towards the implementation of future European standards that seek to promote the implementation of cost saving measures and energy consumption reduction among governments and businesses.

To ensure the interest of all, they have created different programs that cover the most important issues: energy solutions, Circular economy, between social impact and economic profitability, financial instruments and success stories.

Sernoven has been invited to present its innovative consumption and impacts predicting solution for the implementation of energy saving measures, which is aimed at engineering and technical departments in big companies. However, it has preferred to wait to launch a complete module that allows greater integrity.

What is the circular economy?

It is a European initiative that aims to encourage feedback on resources use, reducing materials input and virgin waste production, closing economic and ecological loops or flows of such resources. Resources physical flows analysis comes from the known industrial ecology school of thought. It explains material flows are divided in two types:

1)     Biological nutrients, designed to be re-introduced in the biosphere without incident

2)     Technical nutrients, designed to be moved with high quality in the production system, but without returning to the biosphere.

SMEs must maintain its objective of creating value, implement sustainability policies while maintaining profitability.

The great challenge for companies dedicated to engineering and energy advice is to convince employers of the importance to implement efficiency measures and energy savings, based on its profitability. Most SMEs restrict themself to undertake those short-term impact measures, applying a corrective policy to the production process. There are several reasons that lead entrepreneurs to manage that way, and none of them is exempt from justification. However, despite the uncertainties of future justify any stagnation, it is necessary to realize that the perpetuation of a company goes through applying the balance between short-term impact measures and long-term impact. Nowadays any efficiency measure well calculated generates a guaranteed return as in the following success stories

Climaval Eficiencia energética

Climaval fiel a su temática, celebra la IV Edición: Soluciones energéticas y Economía circular

/in , ,

Avaesen se mantiene fiel a su política de organización de eventos para promocionar las actividades de sostenibilidad, eficiencia energética y reducción de emisiones de CO2 a través del congreso CLIMAVAL. En la pasada edición, la temática se centró en el sector hotelero, este año girará en torno al sector industrial, igualmente necesitado de nuevas ideas, de cara a la implantación de venideras normas europeas que pretendan fomentar la implantación de medidas de ahorro y reducción de consumo energético entre los gobiernos y las empresas.

Para asegurar el interés de todos, se han creado diferentes espacios que cubren los temas más importantes: soluciones energéticas, economía circular, entre impacto social y rentabilidad económica, instrumentos financieros y casos de éxito.

Sernoven fue invitada a presentar en Climaval,su innovadora solución de predicción de consumos e impactos para la implementación de medidas de ahorro energético, que va orientada a ingenierías y departamentos técnicos en grandes empresas. Sin embargo ha preferido esperar al lanzamiento de un módulo más completo que permita mayor integridad.

¿Qué es la economía circular?

Se trata de una iniciativa europea que pretende fomentar la retroalimentación en el uso de recursos, reduciendo la entrada de los materiales y la producción de desechos vírgenes, cerrando los bucles o flujos económicos y ecológicos de dichos recursos[]. El análisis de los flujos físicos de recursos proviene de la escuela de pensamiento de la conocida ecología industrial. [] En ella los flujos materiales son de dos tipos:

  • Nutrientes biológicos, diseñados para volver a introducirse en  la biosfera sin incidentes
  • Nutrientes técnicos, cuyo diseño les permite circular con alta calidad en el sistema de producción, pero sin volver a la biosfera.

Las pymes deben mantener su objetivo de crear valor, implantar políticas de sostenibilidad sin dejar de mantener su rentabilidad.

El gran reto para las ingenierías y empresas dedicadas al asesoramiento energético es convencer a los empresarios de la importancia de implementar medidas de eficiencia y ahorro energético, basándose en la rentabilidad de las mismas. La mayor parte de las pymes, se limitan a acometer aquellas medidas de impacto cortoplacista, aplicando una política correctiva al proceso productivo. Existen varias razones que llevan a los empresarios a gestionar de ese modo y ninguna de ellas queda exenta de justificación. Sin embargo, a pesar de que las incertidumbres del devenir justifiquen cualquier inmovilismo, es necesario tomar conciencia de que la perpetuación de una empresa pasa por aplicar el equilibrio entre las medidas de impacto a corto y las de impacto a largo. Hoy día cualquier medida de eficiencia bien calculada genera una rentabilidad garantizada como en los siguientes casos de éxito

Sernoven App eficiencia energética Valencia Energy

Sernoven desarrolla un sistema innovador para predecir resultados energéticos

/in , ,

SERNOVEN pondrá en el mercado una aplicación de desarrollo propio y fruto de la experiencia acumulada durante años. Con esta App se pretende hacer más cómodo y ágil el proceso de gestión energética por parte de las ingenierías que prestan su servicio a empresas y quieran orientarlo como soporte técnico y asesoramiento hacia la reducción de costes energéticos y la implantación de medidas de ahorro. También ayudará a dar soporte a la labor diaria de los técnicos de mantenimiento.

La herramienta desarrollada permite modelar, sin necesidad de monitorizar previamente, el patrón de consumo energético de una instalación dentro del sector terciario o industrial. La aplicación permite predecir con un elevado grado de certidumbre el consumo energético y coste asociado ante cualquier cambio en las variables de uso de la misma. De esta forma, se dota al propietario y a los profesionales que velan por el buen funcionamiento de la instalación de una herramienta muy potente para simular el impacto de  cualquier actuación o modificación sobre el modelo original, con tal de contrastar un posible ahorro en la instalación. También, entre otros, permite tomar decisiones con antelación teniendo en cuenta el comportamiento de los mercados eléctricos mejorando la gestión energética.

Además, la herramienta pone a disposición del usuario la creación de tarifas personalizadas con las que, introduciendo condiciones de contratación, se podrá realizar una comparativa de costes de consumo según las distintas tarifas. De esta manera, el usuario puede determinar si la tarifa actual es la más adecuada para la instalación.

Esta herramienta estará conectada con los datos de precios del mercado intra-diario para realizar cálculos precisos. En posteriores versiones, la planificación de desarrollo contempla lanzar un módulo de alertas basándose en las predicciones meteorológicas, de modo que si una ingeniería presta soporte a clientes en diferentes lugares, podrá dar consignas para una gestión más precisa aprovechando las condiciones y minimizando el impacto de los cambios de temperatura ambiental. Esto será muy útil para personalizar la gestión en los casos de múltiples puntos de suministro dispersos por toda la geografía nacional.

Con todo lo anterior, se reduce significativamente la incertidumbre ante la toma de decisiones por disponer de una herramienta que con antelación simula el impacto de potenciales medidas de ahorro y gestión energética, facilitando la labor de Gerencia. Una vez más, el departamento de I+D+I de Sernoven consigue aportar valor a sus clientes y estar en la vanguardia del sector de la eficiencia energética.

 

Sernoven App eficiencia energética Valencia Energy

Sernoven developed an innovative system to predict energy results

/in , , ,

SERNOVEN will put on the market a self-development application and result of the experience accumulated over the years. With this app we aim to make more comfortable and agile the energy management process for engineering companies which provide its services to business and would like to direct it as a technical support and counsel towards energy cost reduction and implementation of cost saving measures. It will also help maintenance technicians with the daily work giving them a new support.

The developed tool allows modeling the pattern of energy consumption of an installation within the tertiary or industrial sector without having to monitor. The application can predict with a high degree of certainty energy consumption and cost associated faced with any change of used variables of the application. Thus, we give to the owner and professionals who ensure the proper functioning of the installation a very powerful tool to simulate the impact of any action or modification of the original model, with the purpose to contrast potential savings in the installation. Furthermore, among others, let make decisions in advance considering the behavior of electricity markets improving energy management.

In addition, the tool let the user to create personalized rates with which, by introducing contract conditions, you will be able to make a comparison of costs for different consumption rates. In this way, the user can determine if the current rate is the most suitable for the installation.

This tool will be connected to the intra-daily market price data for accurate calculations. In later versions, development planning plans to launch an alerts module based on weather forecasts, so that if an engineering services company provides support to customers from different locations, they will be able to give instructions for a more accurate management taking advantage of the conditions and minimizing the impact of ambient temperature changes. This is useful to customize management in cases of multiple supply points scattered throughout the national territory.

With all of the above, it significantly reduces the uncertainty facing making a decision with this tool which can simulate in advance the impact of potential cost-saving measures and energy management, facilitating the work of Management. Once again, the R&D department of Sernoven gets bring value to its customers and be in the forefront of the energy efficiency sector.

¿Necesita cambiar la potencia eléctrica contratada en su negocio o vivienda? ¡En Sernoven le contamos todas las claves!

/in , , ,

En muchas ocasiones la potencia eléctrica contratada, debido a la tipología de consumo y la cambiante normativa que establece cómo se factura en cada tipo de tarifa, no se corresponde con el valor óptimo económico. Es por ello, que debe abordarse la optimización de este parámetro para evitar los sobrecostes que implican no hacerlo. Estos son los casos que pueden presentarse:

Do you need to change the electric power contracted in your home or business? With Sernoven you have all the keys!

/in , , ,

In many cases the electric power contracted does not correspond to the economic optimum value due to the type of consumption and changing legislation which establishes how each type of rate is billed. It is, therefore, to be addressed optimization of this parameter to avoid cost overruns involving not to do it. These are the cases that may arise:

  1. If your contracted electric power is less than 15 kW

Until a couple of years ago in electricity supply contracts with contracted electric power less than 15kW. At that time, the legislation established the need for the Distribution company to install in the electrical panel an ICP (power control switch, interruptor de control de potencia in Spanish) in order to limit the simultaneous maximum electrical power that could consume. The calibre (amperage) of this switch was selected based on the electric power contracted.

With the progressive replacement of analogue by digital electricity meter boxes, the situation changes substantially. The new electronic electricity meter boxes have built-in ICP, which has cutting and rearmament capacity. This can “force” many facilities to adjust the value of electric power contracted to the reality of consumption. As long as the 15kW are not exceeded the process is practically automatic and is done through the trading company with which the supply contract has been signed, (customizing it in the ICP electronic meter box, remote), and signing a new contract that reflects the new power.

Facilities with more than 20 years old must pass an inspection (qualified electrician) and register a Bulletin of the Electrical System to the Distribution company and the Department of Industry.

  1. If your contracted electric power is between 15 kW and 451 kW

    A) Transformer intensity needs to be adapted to new powers.

If the new desired electric power is outside the permissible range determined by the Distribution company according to the electrical system transformer intensity, proceed to its replacement hiring a qualified electrician. This is coordinated first by requesting new powers to the trading company with which the supply contract has been signed and contacting at the same time with the Distribution company to report it, confirming the modifications to be made on transformers and then checking them. It is then a technical and administrative management.

          B) No needs to adapt transformer intensity to new powers.

If the new desired electric power is inside the permissible range determined by the Distribution company according to the electrical system transformer intensity, it is not necessary to proceed to its replacement hiring a qualified electrician. This is coordinated by requesting new powers to the trading company with which the supply contract has been signed. It is then a purely administrative management.

What if we want to increase the contracted power?

Apart from all the above, the situation may be complicated substantially when to request an electrical power increase. Installation requires a new Bulletin of the Electrical System either because not done in his day (no Legalized system), it is not conserved or because the new desired power exceeds the maximum value indicated in the existing Bulletin of the Electrical System.

A) If it is a home, a small business or industry, and want to increase less than half of what had hired or less than 10 kW in housing, 100 kW in small businesses or 20 kW in industry, an electrician can do all formalities and provide the new Bulletin of the Electrical System.

B) If it is a home, a business or an industry and we need to increase more than 50% of what had hired and power is higher than the values indicated in the previous paragraph, in addition to hire an electrician, ask an engineering company that will carry out the necessary project and will legalize it.

To legalize electrical system and obtain a certified electrical system (called Electric Bulletin) it is necessary an electrical project signed by an engineer needs in addition to the paper signed by the electrician in charge of the work. This new bulletin will be required to contract electrical supply, increase contracted power above the maximum value of the existing bulletin and also to obtain the activity license.

C) If the local has public audience, such as large shops, bars, cafes, clubs, etc. An electrician, engineering and OCA (Administrative Certification Organism, Organismo de Certificación Administrativa in Spanish) services for review of the installation whatever the power increase required to perform will be.

It would also be necessary to undertake adaptation works of the installation, which will require at least an electrical connection adaptation and a general automatic switch of the electrical panel as it is an increase of the electric power.

If the distribution network of your consumption does not have enough power available, the Distribution company could request the establishment of a new power line from a transformer center for the distribution, which will also require engineering project. It should also be responsible to hire the work to be done.

Due to the technical and economic implications of all above, on most occasions when you want to increase the electric power contracted, it will be more efficient and profitable perform an optimization study of consumption facilities and optimum power to hire hefting all factors on the line. If you are planning to carry out this improvement, consult our experts where they provide personalized advice and the best solution for your case.

Se publica el Real Decreto 56/2016 que traspone la Directiva de Eficiencia Energética en España

/in , , ,
  • Las empresas españolas no PYMES tendrán nueve meses para realizar auditorías energéticas o implantar un sistema de gestión energética en sus instalaciones

El 12 de febrero de 2016, el Consejo de Ministros aprobó el texto  por el que se traspone la Directiva 2012/27/UE del Parlamento Europeo y del Consejo del 25 de octubre de 2012 relativo a la eficiencia energética. Establece el marco regulatorio de la eficiencia energética en España en lo referente a auditorías energéticas, acreditación de proveedores de servicios y auditores energéticos, y promoción de la eficiencia energética. 

Tras dos borradores y un proceso de consulta pública, después de más de un año y medio desde que finalizara el plazo de transposición de la Directiva 2012/27/UE y con un expediente sancionador por parte de la Comisión Europea el pasado mes de octubre, la publicación de este decreto es un paso esencial para que España llegue al objetivo del 20 por ciento de ahorro energético para 2020. La finalidad de esta directiva es promover el uso de las energías renovables y poner en marcha medidas efectivas de eficiencia energética en los sectores residencial, terciario, transporte e industria.

Según el artículo 8 de la Directiva, todas las empresas que no sean PYME, independientemente del sector de actividad, están obligadas a cumplir el requisito de realizar una auditoría energética cada cuatro años o bien a implementar un sistema de gestión energética o ambiental —certificado por un organismo independiente con arreglo a las normas europeas o internacionales correspondientes—, siempre que los Estados Miembro garanticen que el sistema de gestión del que se trate incluya una auditoría energética realizada conforme a unos criterios mínimos que aseguren su eficacia y que la Directiva recoge en su Anexo VI.
