Ten years of price evaluation in a renovation market with volatile financial incentives: The effect of Energy Efficiency Obligation on residential market prices
Résumé
The package of legislative proposals under the designation "fit for 55", emphasize the acceleration of the decarbonisation of sectors such as the building sector with increasingly demanding climate standards. Then, it is important to drive investments into the renovation of building stocks and to stimulate the refurbishment demand and ensure that the measures implemented are cost and environmental effective. Thus, under the Energy efficiency Directive, the energy-saving obligation scheme (EEO) in France launched in 2006 incentivise the renovation of dwellings as around 70% of EEO delivered concern the households. In that sense, the knowledge of renovation costs and their integration in techno-economic studies are key components to evaluate efficient measures. In this context, we have been monitoring the prices of housing renovations carried out under the EEO scheme since 2009. We have carried out statistical analyses on a large sample to follow the evolution of prices (average growth rate) as well as the structure of the price distribution. These prices are compared to market prices outside the EEO scheme. Thus, some renovation measures show various price evolutions and rarely a smooth evolution. These contrasting evolutions are analysed regarding the modification of the available financial incentives (EEO, tax credit) as well as the type of EEO (low-income vs. standard EEOs).
