Building, acquiring or renovating one's habitat involves large expenditures that often engage the homeowner over several decades. The need to be reassured and strengthened in his investment, to make the "right choice" is therefore obvious. Since the early 1980s, public and private building stakeholders have developed a multitude of certifications and labels. These concern all aspects of a building: its structural quality, its environmental impact or its energy performance. HandymanDuanche the decor for you to see more clearly.
Certification or Labeling? What differences?
Assured by an independent investigating body and accredited by the COFRAC (French Accreditation Committee), the certification of a building guarantees its compliance with a standard and / or a specific reference system. Its reliability is ensured by an agreement with the State. It can therefore condition the obtaining of certain local, regional or national financial aid.
A public label makes it possible to verify, certify and recognize to a dwelling characteristics corresponding (or superior) to the regulations in force. The certification of these labels can therefore change over time according to the legislation. They allow, more easily the attribution of public aids or tax advantages.
For several years, private labels have also been flourishing. Born from a marketing approach aimed at improving the image of the sector, these labels generally take the form of a more or less formal "commitment" of the signing professional. These declarations or charters of intentions / actions / achievements not covenanted by the State are difficult to verify. Indeed, they are neither uniformly recognized by the professional actors of the field of activity considered, nor attributed by actors approved by the COFRAC.
To certify or label a home: what are the advantages? Certification and labeling are paid services. Checks and verifications (audits, on-site or on-site surveys) are carried out during construction and / or upon receipt of the work.
The conformity of the work is guaranteed by the follow-up of a carefully established specifications. This allows:
In particular to formulate and prioritize precisely its needs and its technical and financial choices.
The professional to be referred in the design, planning and construction of the building. He is thus informed and trained in new techniques and new practices of materials.
After delivery and validation of the construction, recognize and enhance the property with a logo and thus be able to claim a set of financial benefits (PTZ +, device "Scellier"...)
Be careful though! The steps are sometimes numerous and the initial extra cost may surprise or even cause doubt! Keep your goals in mind and balance the cost-guarantee ratio over the medium and long term.
Certifications for the quality of construction.
Certified works, new or renovated, are either individual houses (isolated or grouped) or collective dwellings. Several certification marks are issued in France for certifying bodies:
Cerqual for new housing whether individual, group or collective,
Cerqual Patrimoine for housing of more than 10 years that they are individual, grouped or collective,
Cequami for new or renovated houses,
Promotelec, for new or renovated housing whether individual or collective,
Certivea for new or renovated commercial buildings.
Labels for energy performance.
The certifications mentioned above guarantee an energy performance that complies with the regulations in force. However, it is possible to include a label guaranteeing an energy-efficient housing.
This is the High Energy Performance (HPE) label. The latter is available for new housing in 5 levels of performance and for housing renovated in 2 levels. The highest level and most awarded is the BBC (building low consumption).
The criteria used for this certification are Cref (Reference Consumption in Primary Energy), EnR (use of renewable energies) and Cmax (Maximum Consumption of Primary Energy). The Cref is the consumption threshold for heating and its auxiliaries, hot water, ventilation and cooling. It is fixed by the thermal regulation (RT) in force and constitutes a threshold not to exceed for new housing.
National standards for environmental quality
Sustainable housing has been the subject of considerable interest over the past few years. Global and multi-criteria approaches, considering the building as a whole (environmental footprint and uses of the site), are thus implemented. They are essentially based on the standards advanced by the association HQE (High Environmental Quality).
