[ca] El present projecte te com a objectiu descriure i analitzar la situacio energetica d&#8217;una industria panificadora situada a la comarca del Baix Emporda, aixi com avaluar possibles accions de millora a nivell d&#8217;estalvi energetic Per tal de realitzar aquest estudi d&#8217;eficiencia energetica, s&#8217;ha dut a terme una auditoria energetica amb la que s&#8217;ha pogut recopilar i analitzar la informacio necessaria per al treball en questio. Principalment s&#8217;han examinat els diferents sistemes que fa servir en la industria durant els seus processos rutinaris, la tarifa del subministrament d&#8217;energia electrica de l&#8217;empresa, aixi com un estudi d&#8217;eficiencia energetica de les seves instal·lacions. Gran part de la informacio referent a l&#8217;estudi s&#8217;ha recopilat mitjancant visites in situ a la fabrica, o be, facilitada pel mateix propietari. En primer lloc es citen les principals definicions i conceptes clau per abordar els temes de l&#8217;eficiencia i estalvi energetic, aixi mateix es contextualitza la situacio energetica a nivell internacional, estatal i normatiu. A mes, es defineixen una serie de conceptes relacionats amb el context energetic. En la part central del projecte es descriu la instal·lacio electrica de la planta, tota la maquinaria pertinent i les seves respectives potencies, a mes de l&#8217;analisi de la tarifacio de la propia empresa i el sistema de facturacio amb la companyia de servei contractada. En la part final es presenten les accions de millora proposades, orientades principalment a l&#8217;optimitzacio de l&#8217;energia electrica de la fabrica. Aquestes propostes inclouen el dimensionament de plaques solars a la superficie disponible de sostre de la industria, per tal d&#8217;auto produir energia renovable i d&#8217;aquesta manera reduir el consum d&#8217;energia electrica de la industria i la instal·lacio de lluminaria LED per tal de reduir el consum electric del sistema d&#8217;il·luminacio de la fabrica. Les mesures proposades seran analitzades sempre des d'un punt de vista economic i energetic, amb l'objectiu de facilitar al promotor la decisio sobre l'execucio d'aquesta proposta.

[en] The main goal of this project is to describe and analyse the energy situation of a baking industry located in the Baix Emporda region, as well as to evaluate possible improvement actions at the energy saving level. To carry out this study of energy efficiency, an energy audit has been carried out with which it has been possible to collect and analyse the information necessary for the work in question. Mainly we have examined the different systems used in the industry during their routine processes, the tariff of the electric power supply of the company, as well as an energy efficiency study of their facilities. Much of the information regarding the study has been collected through on-site visits at the factory or provided by the owner himself. Firstly, the main definitions and key concepts to address the issues of efficiency and energy saving are cited, as well as contextualizing the energy situation at the international, state and regulatory levels. In addition, a series of concepts related to the energy context are defined. In the central part of the project the electrical installation of the plant, all the pertinent machinery and their respective powers are described, as well as the analysis of the pricing of the company itself and the billing system with the contracted service company. In the final part, the proposed improvement actions are presented, aimed mainly at optimizing the factory's electrical energy. These proposals include, on the one hand, the sizing of solar panels on the available roof surface of the industry, in order to self-produce renewable energy and in this way reduce the consumption of electrical energy in the industry. And on the other hand, the installation of LED luminaire to improve the lighting system of the factory and also reduce its electricity consumption. The proposed measures will always be analysed from an economic and energy point of view, with the aim of facilitating the promoter's decision on the execution of this proposal.
