Abstract: Chile is a resilient country which has been struck by a series of natural disasters, affecting heritage areas whose inhabitants live under a great economic and energy vulnerability. Although there are some advances that have been made in the country to recover its heritage, these do not include energy efficiency parameters. In this context, intervention in heritage properties requires a specific, complementary treatment above and beyond what is currently applied. Consequently, this research aims to develop a methodology that balances heritage and energy in energy vulnerability contexts. The proposed methodology analyzes heritage and energy aspects separately through attribute matrices, as well as the building pathologies, to later integrate the results in a final matrix which allows defining an energy-heritage intervention plan. In this way, it includes the systematic identification of elements that require intervention because of pathological issues, as well as the type of intervention that would be acceptable given its heritage significance and whether they mean a possibility to optimize the energy performance. The methodology, for its validation, was applied in a heritage residential building inhabited by low-income occupants. The case study presents physical damages and is located in the city of Lota, an area with an outstanding cultural heritage from the mining era.
