Energy efficiency Ventilation Ventilation systems Regulation CTE CTE HS 3

The Technical Inspection of Buildings is a technical control that buildings must undergo every certain period of time. To pass it successfully, it is important to comply with a series of regulations. Next, we show you how ventilation affects an ITE.rn

What regulations influence the ventilation of buildings?

rnYou must take into account that when regulating the ventilation of buildings, it is necessary to comply with one of the following regulations: the RITE (or Regulations of Thermal Installations in Buildings), and the other the HS 3 of the Technical Code of Construction (or CTE), in the case of homes.

The HS 3 of the CTE regulates indoor air quality and addresses the following issues:rn

    rn t
  • The inside of homes, storage rooms, parking lots, garages, and waste storage areas.
    • rn t
  • In buildings that are not used as housing, parking lots, and garages.
    • rn
rnOn the other hand, the RITE is responsible for controlling the following issues:rn
    rn t
  • The rest of the buildings that are not covered by the HS3 of the CTE regulation, which are generally all industrial and service (commercial, hospitality...) buildings.
    • rn
rnAs you can see, HS 3 of the CTE is a regulation that applies to all types of homes, single-family houses, duplexes..., and also to garages, parking lots, and storage rooms. Meanwhile, in buildings that have a different use and in premises the RITE regulation applies. Due to what has been mentioned, homes must have their own air renewal system.rn

How does ventilation influence an ITE of any building?

rnWithin the ventilation of homes, account must be taken of the admission of air to dry areas and also of the extraction of air from humid areas, this will be so regardless of the system employed. What are the air renewal systems for homes that are within the HS 3 of the CTE regulation? They are the ones we review next:rn
    rn t
  • Exclusively natural ventilation. It is the one that occurs when the windows of the home are opened. It is not accepted by HS 3 of the CTE, so it cannot be used exclusively in homes.
    • rn t
  • Hybrid ventilation. This system combines natural ventilation when there are appropriate temperature and pressure conditions; when this is not the case, forced ventilation will be activated. For this to occur, the air ventilation ducts located in humid areas must be vertical and have a larger section than those of exclusively mechanical ventilation.
    • rn t
  • Mechanical extraction ventilation - Simple Flow. It involves mechanically extracting air from humid spaces. In these cases, the air intake from dry areas can be natural, using grilles in the windows or on the facade. The extraction tubes may be smaller, and also the number of chimneys located on the roofs.
    • rn t
  • Double Flow Mechanical Ventilation. These are the ones used in passive houses, Passivhaus, since heat losses through ventilation are almost nonexistent, since they incorporate a heat recovery unit that recovers the heat from the extracted air to the incoming air. They are suitable for all climates, as it is not necessary to keep the windows open for ventilation.

rnVentilation influences an ITE, since when this inspection is carried out, it is necessary to check that the systems are functioning properly and are not obstructed in any way. It is advisable to have them regularly checked by a specialized company to ensure optimal operation.
