The portuguese housing stock: An initial analysis of the National Energy Certification

Abstract

This paper provides a first statistical analysis based on a number of residential building energy certificates aiming at contributing towards a better thermal characterization of the current mainland Portuguese residential building stock. The analysis underlines the importance of several certification parameters, such as climate and location, period of construction and others, in regards to the rating outcomes. Furthermore, the general impact of suggested improvement measures on the expected energy demand, the certified energy rating and the estimated energy savings are explored.
