Paris, the challenges of major energy renovation of over half the housing stock

In 2018, 567,000 main residences in Paris were rated as having an energy performance certification (EPC) of  E, F or G. Paradoxically, the heating expenditure per housing unit and per inhabitant was the lowest of Ile-de-France departments due to housing being more often collective and small in size.

Up until the present day, these EPC labels have had little impact on the purchasing or renting of housing. The 2021 Act known as Climate and Resilience encourages the renovation of housing with the lowest ranking. To achieve this, aid schemes have been expanded and are now available for all property owners (both occupants and lessors).

In Paris, in 2018, 567,000 main residences were diagnosed as having an energy performance rating of E, F or G. This represents more than half (54%) the Parisian main residence, housing stock (sources). Among these, 326,000 were classified F or G, categories equivalent to “thermal sieves”. The proportion of housing classified E, F or G is much higher in Paris than regional (45%) or national (41%) levels. Indeed, recent construction, with better energy performance (figure 1), is less frequent in the capital : the percentage of housing built after 1975 represents only 21% of the total stock, compared with 42% in the region as a whole.
