Abstract

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. The aim of this work is to analyse the methodology used by current regulation to estimate the energy consumption from domestic hot water systems and its subsequent energy rating. The relationship of the results obtained with the different types of homes is studied according to their area and number of bedrooms, justifying how the area of the house has an excessive influence on the qualification obtained in the sanitary hot water parameter, favouring a better certification to larger homes.
