| It is an European Union aim, and of its member States, to reduce significantly their energy consumption and their dependency on fossil fuels. According to Directive 2010/31/UE of the European Parlament, about 40% of the energy consumption comes from buildings, so the reduction of that consumption in buildings must be an important part of the necessary steps to reduce that energy dependency and greenhouse gas emissions. In order to improve the energy efficiency, energy certification plays an essential role allowing us to evaluate and compare buildings and their features related to demand, consumption and emissions. Energy certification, regulated by Royal Ordinance 235/2013, could be only done using recognised documents by both Ministry of Public Works and Transports, and Ministry of Industry, Energy and Tourism. As it can be observed in the study of Gangolells et al., in which data of more than 129.000 energy certifications from existing buildings are assessed, the energy consumption from heating is been significantly reduced due to new regulation which increase the requirements reducing the demand and consumption energy of this systems. This makes that energy consumption from domestic hot water (DHW) increased its relative importance in residential buildings. That increasing importance justify the aim of this work, which is to analyse the methodology used by current regulation to estimate the energy consumption from DHW systems and its subsequent energy rating. | |
