摘要
The aim of the article is to study the energy efficiency improvements feasibility through the analysis of energy savings and economic investment. The results were obtained from a model studied with different orientations, building systems and interventions, including two retrofit options regarding thermal transmittance, specified in Appendix D of the DB-HE Order FOM / 1635/2013, in order to generate different subcategories of buildings. The analysis was developed on demands and consumption obtained from a tool created based on the UNE-EN-ISO-13790: 2011 and ASTM-E917: 2013. Once obtained the results it was made an energetic and economic results comparison. This paper evaluates economics and energy efficiency savings improvements, for dwellings, comparing various alternatives according to the initial situation, in order to deepen into valid indicators for energy efficiency actions in existing buildings.
