About energies-maison.fr
energies-maison.fr provides a free online simulator that estimates a household's yearly gas and electricity losses from its surface, heating type and current energy bill. Users can refine the estimate using construction year, insulation quality and climate region.
The site is aimed at households in France that want to lower heating and electricity costs. After a simulation, visitors can request a callback from an advisor who reviews their situation and suggests solutions. The site also publishes energy-saving guidance on insulation, thermostat settings and heating equipment such as heat pumps and high-performance boilers.
The site is published in French. Its estimates are described as indicative and based on national averages, with actual savings varying by insulation and usage.
