CAE system
The CAE system (Energy Savings Certificate) is a mechanism that promotes energy efficiency in renovations and construction projects, offering certification for the improvements made and partial refunds to those who implement them.
This system encourages sustainable practices, reduces energy consumption, and formally recognizes improvements, which can increase property value and enhance the image of companies committed to sustainability.
The CAE drives and rewards energy savings, benefiting both individuals and businesses as well as the environment.

Process
01
Contact with KG Ecología
Contact us, and we will guide you through the process so you can obtain the maximum refund for your energy efficiency measures.


02
Submit documentation
We will request the necessary documentation to carry out the feasibility study and later calculate the final savings and determine how many CAEs are obtained.
03
Verification
Once the study and calculations are completed, they are sent to the verifier (certified by ENAC) to validate and confirm this data.


04
Refund delivery
Finally, the number of CAEs obtained is verified, and the corresponding refund for that energy savings is delivered.
Sheets Tipology
For all those energy efficiency actions that are, by their nature, more complex or particular, the creation of what we know as "singular cards" is proposed.
For this type of actions, no specific calculation formula has been proposed, so each obligated or delegated party that performs the energy savings calculations will rely on their own knowledge to justify such savings.
If you're not sure whether your energy efficiency action is standardized, you can use our MITECO card search tool to confirm.
If you have any questions, feel free to contact us and we will help you find the best solution.
Sectors of activity
The Ministry for Ecological Transition and Demographic Challenge (MITECO) has proposed a series of standardized measures, organized by sectors, that detail specific energy-saving actions.
