Green value: why sustainable properties will increase in value in the next 10 years
The concept of green value has become prominent in French real estate vocabulary in recent years. Initially marginal, almost confidential, it has now become a structuring factor in the market. Notarial studies now systematically measure the price difference between energetically efficient properties and equivalent, poorly performing properties. This difference is steadily increasing due to regulatory changes, rising energy costs, and buyers' awareness. Here's why green value will continue to grow in the next ten years, and what this concretely means for a real estate investment project in 2026.
What exactly is green value
Green value refers to the proportion of real estate value added (or subtracted) to a property based on its energy performance. The concept was formalized by French notarial studies in the 2010s, which began systematically measuring price differentials between comparable properties on all criteria except the energy performance certificate.
