Energy Refurbishment Assessment of an Existing Educational Building. A Case Study

Abstract

The building sector is the highest energy consumer (38.1%) in the European Union. This consumption has to be reduced in both new and existing buildings. Respect to the existing ones, they need an effective energy renovation as the current European Directives reflect. Specifically, all countries have to refurbish 3% of their public buildings per year since 2014. In this paper, several refurbishment measures have been applied to the Energy Department Building of the University of Oviedo, using simulation tools. The measures proposed modify the thermal envelope according to the climatic variables and normative restrictions. Also, a parametric analysis has been made studying the influence of these measures in the heating and cooling demand and quantifying their cost.
