Description
Analysis of energy renovation costs, as provided by the French Observatory for Low Energy Buildings, identified the following:
- One-step deep energy renovation is achieved in France at an average renovation cost of €316/m²for dwellings in multi-family buildings and €374/m² for detached single family homes.
- A cap on energy consumption and a cap on the cost of one step deep energy renovation make energy renovation companies changing their business model.
- Private investors should be attracted by one-step deep energy renovation as the return on investments is well above 5% in more than half of French projects.
- Industrialisation and digitalisation of one-step deep energy renovation will lead to further cost reduction.
