The energy database augmented by AI

Geolocated data for realistic analyses

namR has created the exhaustive energy database geolocated at the address level to define decarbonization trajectories & offer strategies based on the reality of the energy renovation potential of your portfolio or territory.

Why is it innovative?

Territorial intelligence optimised by our AI

namR's expertise in AI and Big Data, combined with our business expertise in housing heat engineering and morphology, has enabled us to develop the most advanced housing energy database on the market (complete for 100% of residential buildings and exhaustive for key data).

Geolocalised data

All namR energy data is available at postal address level thanks to our geocoder.

Reliable data

The namR calculation engine, designed by experts in energy renovation, is based on open data and benchmark market data to provide neutral, reliable results.

Educational data

namR has gone further than the DPE and now offers a financial estimate in line with the reality of the market (cost of work, national and local grants and energy savings) and a personalised estimate (budget or list of work).
