In addition to UNI 10339, it is important to also consider other standards and regulations:
D.Lgs. 81/2008 (Consolidated Law on Occupational Safety)
The main reference standard for air exchange in Italy is UNI 10339:1995. Although currently under revision, this standard still provides useful guidance on the necessary external and extraction air flows to ensure a healthy environment in different types of premises, including those you mentioned.
Key points of UNI 10339:
Air flows: The standard specifies the minimum external air flows to be introduced and stale air to be extracted, based on the intended use of the premises and the number of occupants.
Ventilation ratio: This parameter indicates the ratio between the surface area of openable components (windows, doors, etc.) and the floor area. The standard sets minimum values to ensure adequate natural ventilation.
Number of air changes per hour: Indicates how many times the air in a room must be completely renewed in an hour.
Application of UNI 10339 to the mentioned premises:
Kitchens, bars, pastry shops, restaurants: These premises are characterized by high production of heat, humidity, and odors, thus requiring more intense air exchange compared to other environments. The standard provides specific air flows for these activities, which vary based on the area of the premises and the number of occupants.
Work environments: Air exchange in work environments is essential to ensure the well-being and health of workers. UNI 10339 provides specific guidelines for different types of work activities, considering the type of pollutants present and the level of crowding.
Dining rooms, canteens: In these premises as well, it is important to ensure adequate air exchange to avoid the accumulation of odors and humidity. The standard provides specific air flows based on the area of the premises and the number of occupants.
In addition to UNI 10339, it is important to also consider other standards and regulations:
D.Lgs. 81/2008 (Consolidated Law on Occupational Safety): This legislative decree establishes the minimum safety and health requirements in work environments, including those related to air quality.
Local building regulations: Municipal building regulations may contain specific provisions on air exchange in buildings, which must be respected during the design and construction phases.
Recommendations:
Consult a qualified technician: To ensure the correct design and installation of ventilation and air exchange systems, it is advisable to consult a qualified technician (engineer, architect, industrial expert) who can assess the specific needs of the premises and correctly apply the current standards.
Consider the specific needs of the premises: In addition to the guidelines of UNI 10339, it is important to consider the specific characteristics of the premises, such as the presence of pollution sources, the level of crowding, and local climatic conditions.
Plan regular maintenance of the systems: To ensure the efficiency and longevity of ventilation and air exchange systems, it is essential to perform regular maintenance, including cleaning filters, checking fan operation, and controlling air flows.
