Assessment of Shallow renovations 2025

April 2025 - November 2025

Funding entity Fundación Naturgy


This project aims to carry out a mixed assessment (with objective and subjective data) of the impact on energy poverty of the shallow renovations carried out by the Naturgy Foundation and the collaborating NGOs within the framework of the Solidarity Fund for Energy Rehabilitation. The impact analysis is carried out based on the characteristics of the home and the energy bills before and after the refurbishment, comparing the actual expenditure with the required energy expenditure of the household. The calculation of a hidden energy poverty indicator is proposed to measure the objective impact of the intervention on energy poverty. Moreover, the subjective indicators of inadequate temperature (both in winter and summer) are estimated to analyse the change in the perception of comfort in the dwelling. Finally, and depending on data availability, a disproportionate expenditure indicator is also calculated.


Layman's summary: This project conducts a comprehensive assessment (objective-subjective) of the impact of shallow renovations on energy poverty, within the framework of the Naturgy Foundation's Solidarity Fund for Energy Rehabilitation.
