The RT 2012, what you need to know

Because of energy efficiency regulations called RT 2012, all building permits nowadays have to contain an annexe which is the BBIO. This officially formatted document proves that the planning of the future property has taken into account an energy efficiency estimation corresponding to the climatic zone (three zones in France).

The regulation fixes a maximum limit (BBIO max) and its calculation includes (among other things) the direction the future house will face, its altitude, the insulation values of floors, walls, loft space and doors and windows. (It also includes a minimum surface for windows : 1 sixth of the floor surface)

Energy efficiency survey

Once the BBIO is done, it need to be completed with another study. Two necessary indexes are required, the normal interior temperature, especially in summer (TIC) and the CEP, concerning heating, water heating systems, ventilation, cooling and lighting.

The RT 2012 is not valid until all of this information is given. The BBIO document by itself does not prove that the building respects the norms.

Air permeability test

Once the building is finished, you need to provide a document proving it is permeable to the air. The requirements mentioned in the last two paragraphs would be pointless if your house is not draught proofed. The test is carried out by professionals who check for any hidden draughts via windows, doors etc.

The RT 2012 certification once all work is over

This certification is carried out by an independent expert and validated by the ministry. It should be registered at the local town hall at the same time as the declaration of finished work.

Important : If you have a bank loan, these documents will be required by the banker before you can receive the last funds, finalise the bank dossier and start the repayment plan.

Make no mistake : all of these steps are complex and expensive. Building your future home within the framework of a building contract (CCMI) ensures that this procedure is followed to the letter.
