Climatización eficiente | Efficient HVAC www.futurenergyweb.es 70 FuturEnergy | Julio-Agosto July-August 2017 nadas al impulso del proyecto, para facilitar el acceso a la actuación para aquellas personas con ingresos limitados y dificultades para obtener la financiación. Estas ayudas permitirán a esos titulares de viviendas afrontar un porcentaje de los costes no subvencionados de la actuación de rehabilitación, porcentaje que oscilará entre un 25% y un 85% de los costes no subvencionados, en función de los ingresos familiares de la unidad convivencial. Además del Fondo de Garantía, también se ha habilitado otro instrumento para facilitar la financiación de la parte del proyecto no cubierta por las ayudas públicas A este convenio financiero promovido por VISESA se han adherido Kutxabank, Laboral Kutxa, Bankoa y Rural Kutxa. En este convenio se regulan unas condiciones financieras muy interesantes para que tanto los vecinos a nivel particular, como las comunidades, puedan acceder a préstamos de entre 8 y 12 años de vencimiento, que les permitan afrontar unas cuotas mensuales del préstamo acordes a su capacidad financiera. Este proyecto supondrá un gran empuje al aprovechamiento de la energía renovable de la biomasa en Álava, que se va a realizar a través de una red de calor urbana, un concepto ampliamente extendido en Europa y que supone una de las formas más eficientes de utilizar esta energía. Álava es un referente en el aprovechamiento de biomasa y en materia de desarrollo energético sostenible. Grosso modo, en Álava están en marcha más de 1.000 instalaciones de generación de calor mediante biomasa, pertenecientes tanto al sector residencial como al industrial, primario y de servicios. En conjunto, son casi 30 MW instalados. Existe un gran margen para el aprovechamiento de la biomasa en los montes de Euskadi, ya que puede pasar del 57% a suponer el 72% de la energía renovable consumida en la región. Biomasa para generar calor en el barrio La red de calor es un sistema para producir y distribuir el calor generado de forma centralizada para un conjunto de usuarios conectados a la misma, pero que permite el uso individualizado de la calefacción para cada vecino. El calor se produce en la nueva central junto al centro cívico de Aldabe y se distribuye a través de las tuberías que discurren enterradas hasta la subcentral en cada edificio (actual sala de calderas en los bloques en donde ya existe calefacción central). En aquellas viviendas que dispongan de calderas individuales, estas se sustituyen por un armario de suministro de calefacción y agua caliente con su contador de energía individual. infrastructure. This threshold stands at 750 homes. To obtain this neighbourhood support, residents must have access to alreadydefined information. This is why the civic centre has hosted a series of seminars to listen, exchange opinions and learn about the experiences of individuals that have taken part in similar refurbishment projects as well as clarify issues with professionals fromVisesa, the Vitoria-Gasteiz City Hall, EVE and Giroa-Veolia. During the seminars, several informative sessions were held to provide details on the project and share the experiences in other districts. There were also five thematic discussions on the ‘urban space’, ‘energy refurbishment’, ‘contract and financing’, ‘district heating’ and ‘other experiences’ in which attendees were able to ask questions. The Basque Government and the Vitoria-Gasteiz City Hall have decided to authorise the concession of funding to complement the monies allocated by European, regional and local entities to promote the project, facilitating access for people with limited means and those who have difficulty in obtaining financing. This funding will allow homeowners to bear a percentage of the non-subsidised costs of the refurbishment actions, which varies between 25% and 85% of the non-subsidised costs, depending on the family income of a typical home. In addition to the Guarantee Fund, another instrument has been authorised to finance part of the project not covered by public monies. Banking entities Kutxabank, Laboral Kutxa, Bankoa and Rural Kutxa have all signed up to this financial agreement, put into place by Visesa. It includes some very attractive financial conditions so that residents in their private capacity, as well as communities, can access 8 to 12 year loans, allowing them to make monthly loan repayments in line with their financial means. This project will be a huge boost to the use of renewable energy from biomass in the Álava region. It will be used in a district heating network, a concept widely implemented in Europe and which represents one of most efficient ways of utilising this energy. Álava is a reference in the use of biomass and in sustainable energy development. Broadly speaking, there are more than 1,000 heat generation installations in progress that use biomass, belonging to the residential and industrial, primary and services sectors, totalling almost 30 MW installed. There is huge potential to use biomass in the hilly Basque Country, with figures that could rise from 57% to account for 72% of the renewable energy consumed in the region. Biomass to generate heat in the neighbourhood A district heating network is a centralised system that produces and distributes the heat generated for a group of users connected to the network, however allows each resident to use the heating on an individual basis. The heat is produced in the new plant adjoining the Aldabe civic centre and is distributed by means of pipes that run underground to the substation in each building (the current boiler room in those blocks where central heating had already been installed).
