Impact estimates of the actions for the rehabilitation of energy efficiency in residential building

Abstract

The prediction of energy savings and indoor air quality resulting from the implementation of rehabilitation measures for energy efficiency in residential buildings is paramount to invest in the right technology and optimize available resources. In this paper, we propose a new methodology, based on actual data collection, to quickly and effectively assess energy efficiency and air quality of housings, considering variables such as the customs of the occupants, regulations and the constructive typology. The effect corresponding to the reforms carried out for energy efficiency rehabilitation in four homes built at different periods, under different rules, with different levels of occupancy and characteristics of its constructive elements is evaluated successfully.
