Home renovation: it works in Paris!

The Apur agency conducted a preliminary assessment of 51 social housing renovation projects in Paris. This resulted in significant savings for households and a substantial reduction in CO2 emissions.

It's important not only to develop climate action plans.

But also to assess the results of work halfway through. This is exactly what the Paris Urban Planning Workshop (Apur) did. In their study published in March, they attempted to evaluate the actual energy consumption in Parisian residential buildings (gas, electricity, and heating consumption), as well as the effectiveness of efforts to improve energy performance under the Paris Climate Plan. The goal is to determine whether the capital's owners (particularly social landlords) are on the mitigation trajectory outlined by the City in its climate plan.

To do this, Apur experts analyzed actual energy consumption.

In 76,515 housing units managed by the three main social landlords in Paris (Paris Habitat, Régie immobilière de la ville de Paris, Elogie-Siemp), the 2022 assessment includes the consumption of five types of domestic energy: heating, cooling, lighting, hot water production, and auxiliary systems (pumps and fans). One in five housing units assessed by auditors (32%) is equipped with an individual gas boiler, compared to 24% connected to a collective gas boiler, and 23% equipped with individual electric heating. About a third of the housing units are connected to the heating network owned by the Paris Urban Heating Company (CPCU). Heating accounts for about 60% of the kilowatt-hours consumed by Parisians. Those using collective heating consume 153 kWh/m² per year, while those with individual heating consume 88 kWh/m² per year.

To summarize

It can be noted that against the backdrop of global climate challenges, the efforts invested in the renovation of social housing in Paris are indeed paying off.
