The purpose of this programme is to support the widespread adoption of the current Building Book for refurbishment through grants that cover part of the costs of professional fees for the issue of the reports and of drawing up detailed proposals for the overall refurbishment of buildings.

The Book that tells you the condition of a building

This grant programme is for ownership associations for residential buildings constructed before 2000 and who wish to prepare a Building Book or refurbishment proposals.

A Building Book is a technical report that describes the characteristics of a building and tells owners how a building should be used and maintained to extend its useful life and stop it from deteriorating. The report also describes the steps to achieve the required increases in energy efficiency.

EU Next Generation funds meet part of the costs of this diagnostic report incurred by owners who show that they wish to carry out refurbishment or restoration works.
