Abstract

Two main targets of European and French energy policies are reduction of energy dependency and greenhouse gas mitigation. Energy conservation is unavoidable in order to reach these two goals.

The Building sector is the largest end use in Europe, and also the largest CO2 emitter (if power plant emissions are included in final energy consumption). It is now well admitted that drastic decrease of buildings energy consumption and CO2 emissions need an intensive retrofitting of building stock, especially housing.

This work evaluates various refurbishment scenarios outlook for 2030 of French dwelling stock: Business As Usual (BaU) or accelerate rates, usual technologies or Best Available Technologies (BATs). Emerging technologies (not yet available but with strong potential) are introduced among “on the shelf” technologies. Studied scenarios include energy efficiency actions as well as energy substitution. Estimations of technical investment cost of studied scenarios are presented.

The calculations are done using the MIeL « Modeling of the Impact of Energy measures for housing » software, developed by EDF and built following a bottom-up approach.
