Estudio de viabilidad, en función de la zona climática, de tres sistemas de climatización y producción de ACS (Agua Caliente Sanitaria) sobre la base del nuevo Código Técnico de la Edificación (CTE2018) en su sección de Ahorro de Energía HE. Aplicación a una casa unifamiliar aislada de 250m2

Abstract

[ES] Losfabricantes de equipos de producción de ACS (Agua Caliente Sanitaria) y de climatización están preocupados por el impacto que el nuevo CTE2018‐HE va a tener sobre el futuro mercado del sector y pretenden descubrir cómo orientar su oferta y producción en el corto/medio plazo. La pregunta que se pretende responder es ¿Qué sistemas son posibles o viables por zona climática? El presente trabajo se trataría de un sub‐proyecto dentro de un proyecto de consultoría. El caso de estudio que nos ocupa se centra en una casa unifamiliar aislada de lujo de 250 m2 útiles. En primer lugar, se analizará el Documento Básico Ahorro de Energía en sus distintas secciones haciendo hincapié en las secciones HE0 (regulación del consumo de energía primaria, total y no renovable), HE1 (requisitos térmicos de la envolvente del edificio y su ganancia solar) y HE4 (cobertura solar mínima de energía renovable para la producción de ACS). Posteriormente y tras seleccionar 4 localidades en las que se realizarán las distintas simulaciones de los sistemas de seleccionados, se definirán los materiales que compondrán la envolvente térmica del edificio acorde a cada una de las distintas zonas climáticas para cumplir el HE1. Una vez seleccionadas se analizará la demanda energética del edificio. Se seleccionarán tres sistemas diferentes para la producción de ACS y climatización. Se verificará si dichos sistemas cumplen la normativa vigente en cada una de las localidades o por lo contrario, no pueden ser instalados en distintas regiones. Finalmente, se realizará una breve discusión del cambiante panorama nacional motivado por los nuevos cambios introducidos en el CTE DB HE y la realidad de los sistemas.

[EN] The manufacturers of air conditioning equipment are concerned about the impact that the new CTE2018‐HE will have on the future market of the sector and they intend to discover how to orient their offer and production in the short/medium term. The question they want to answer is: Which systems can be accepted en each climate zone? This essay would be a sub‐project within a consultancy project. The case study that we are dealing with is focused on an isolated luxury single‐family house of 250 useful m2. Firstly, the Basic Document on Energy Saving will be analyzed in its different sections, emphasis on sections HE0 (regulation of primary energy consumption, total and non‐renewable), HE1 (thermal requirements of the building envelope and its solar gain) and HE4 (minimum solar coverage of renewable energy for the production of DHW). Subsequently and after selecting 4 locations where the different simulations of the selected systems will be carried out, the materialsthat will compose the thermal envelope of the building will be defined according to each climate zones in order to comply with HE1. Once selected, the energy demand of the building will be analyzed. Three different systems will be selected for the production of DHW and air conditioning. It will be verified if these systems are accepted by the CTE2018 with the regulations in force in each of the locations or wether, on the contrary, they cannot be installed in different regions. Finally, there will be a brief discussion of the changing national panorama motivated by the new changes introduced in the CTE DB HE and the reality of the systems.
