Abstract:
The energy retrofit of public buildings, especially schools, supposes an important energy and economic saving, mainly because of their high consumption to ensure adequate thermal comfort, since the majority of users of these buildings are children. To achieve this goal, it is necessary to develop an action plan to analyse the different energy improvement options of the set of schools and establish efficient intervention levels, making the economic investment of the government profitable. Due to the large number of schools, the characterization by types, both morphological and constructive, has been proposed, so that the results obtained for each type can be extrapolated to those of similar characteristics. It is important to know what is the level of intervention that allows one to achieve the greatest energy savings with the lowest global cost for each type.
The present work includes the energy study of a public school according to the optimal cost method, specified in the European Directive on energy efficiency. This methodology considers the overall costs over a period of 30 years for each level of intervention and identifies which is the most efficient energy retrofit strategy.
