New UNE standard for ventilation in car parks

05/09/2019

The The Spanish Association for Standardization, UNE, has published a new Spanish standard UNE 100166 Climatización. Ventilación de aparcamientos. This standard, which has recently been revised, updates the design criteria for ventilation systems in car parks in line with the requirements of the Technical Building Code.

The standard is the result of a collaboration between two UNE Technical Standardization Committees: CTN 23 Fire safety, managed by TECNIFUEGO-Spanish Association of Fire Protection Societies, and CTN 100 Air Conditioning, led by the Association of Air Conditioning Equipment Manufacturers (AFEC). It was developed by members of both technical committees, and is the result of a consensus between all the parties involved.

This revision includes the use of ventilation systems in car parks so that these meet requirements on health as well as smoke extraction in the event of a fire, and has declassified car parks as places at risk of explosion. It also considers criteria for increasing energy efficiency and the economy of the system.

The standard provides the specifications necessary to design ventilation systems in car parks using existing technologies:

  • Natural ventilation
  • Natural ventilation assisted by impulse ventilation
  • Mechanical ventilation
  • Mechanical ventilation assisted by impulse ventilation

The standard also details the criteria for installing gas detection systems, including the installation of NO2 detectors in addition to the CO detectors traditionally found in car parks.

Standards are effective tools for supporting the implementation of public policies and legislation. In fact, 12% of the UNE Standards catalogue appears in national legislation.
