In the current context of ecological urgency, there are very high expectations for the transformation of the building stock. A whole European regulatory context has gradually been put in place around this, forcing public authorities, businesses and private individuals to commit to transforming the building sector so that it can meet the challenges of decarbonisation, climate risk prevention and the protection of life.

Firstly, by reducing their carbon footprint: Europe is committed to reducing building emissions by 60% by 2030. The levers for implementation are essentially linked to energy renovation and exploiting the potential for renewable energy production associated with buildings (photovoltaics in particular).

Secondly, by estimating their vulnerability to climate change and identifying adaptation measures. The new European CSRD (Corporate Sustainability Reporting Directive) requires companies with more than 250 employees to take into account 'physical' climate risks in their non-financial reporting. In addition, financial organisations such as banks and insurance companies are subject to ever-increasing reporting requirements from the ECB. For example, in 2023, the ECB will require every financial organisation to carry out a rigorous assessment of the impact of climate change on its activities and financing, and to put in place an action plan (adaptation plan) to mitigate the effects. The first reports enabled climate stress tests to be carried out, which were widely reported in the media.

The exposure of the property portfolio financed by banks, insured by insurers, or held by corporate customers is a significant part of this reporting, and requires data specific to buildings.
