After a detailed visit of a given building, and the analysis of the constructive and technical elements supported by an energy assessment, the Estia team is able to draw refurbishment strategies adapted to the building owner objectives.

The energy analysis can be supplemented by a comprehensive review of the state of degradation of the building and the technical installations. The team of Estia also offers complete monitoring including verification of actual consumption before and after refurbishment.


The "EPIQR+" diagnosis method, that is developed and maintained by Estia, allows for a systematic approach of the building degradation status (housing, administrative buildings, hospitals, schools, shopping centers, etc.).
Several hundred buildings were examined by Estia with this method since 2003. When appraisals relate to a set of of buildings, it allows the manager to have a global overview on the building stock and facilitates planning refurbishments.
