UNI 11367: 2011 certification requirements NOISE FROM THE CASE FOR.
Here is an article published on Il Sole 24 Ore on July 22 www.ilsole24ore.com obligation of noise certification.
"In 2011 those who want to sell or rent an accommodation must provide it, as well as energy certification, including the noise certification. The requirement will be introduced in the order expected in the autumn, which will incorporate the Uni 11367 ('Acoustics in buildings - Rating of sound housing units - Evaluation and verification work' available on the website) the institution of the Italian national unification is to publish. Classification acoustics of a building unit (be it an apartment or detached house), will then become necessary.
evolution legislation in place, in fact, preceded by recent regional laws (such as Law 34/2009 of Calabria) requires each housing unit has a noise certificate attesting to his membership in class acoustics. It is a concept similar to that of the energy certificate, but with some major differences, the main is the fact that while the energy certificate is drawn up, based on calculations, the noise certificate shall be drawn on the basis of a test (test) performed on all the rooms of the apartment.
The results in all rooms, given the uncertainty of the measures and made an average is an index that will derive the noise classification in four classes real estate unit. Consequently, the noise certification costs will be very different from those of an energy certificate (five to ten times more) and, in addition, the noise certification will be valid for a limited time. The Uni 11367
be mentioned explicitly in the standard arriving in autumn and this is of particular relevance. Explain how to perform noise tests allowing buildings to inform future owners / residents on the same acoustic characteristics, and to protect the various actors involved in building process (designers, manufacturers of building materials, manufacturers, vendors, etc.) from any possible future disputes.
The standard applies to all types of buildings, except those for agriculture, trade and industry. Within the scope of the rule, the acoustic requirements of hospitals, clinics, nursing homes and schools are defined by a specific appendix.
There are four different classes of acoustic efficiency, class 1, which identifies the highest level (quieter), class 4, which is the lowest (louder): It is considered that, even if the performance level "core" is the third class, the vast majority Italians existing buildings do not even reach the fourth grade. The current decree in force, the DPCM December 5, 1997, provides unique reference values \u200b\u200bvery close to those of the third class of the Uni.
The overall assessment of acoustic efficiency of each housing unit comes from assessments for each requirement, are subject to a classification of facade insulation, isolation from neighbors (both for aircraft noise, both for foot traffic noise) and the noise level of the plant. In the case of the hotels are also considered as the noise insulation between rooms in the same unit (for example, between the rooms).
The rule of acoustic classification of buildings improves the framework of information available to the user of the asset building. Framework, with the mechanism of graded classification, gives a good new economic value related to the ability to meet the same needs are often intangible (convenience, privacy, CO2 emissions, material consumption).
The test is performed by an expert in all areas of the house. The criteria are: insulation of the façade, isolation from neighbors, noise level of the plant. The hotels is also tested for insulation between the rooms
The certification will be required for all types of buildings (also for single-family homes) except for agriculture, trade and industry. For hospitals, schools and nursing homes requirements aids are contained in Appendix to the rule. "
