PD CEN/TS 18335:2026

This standard PD CEN/TS 18335:2026 Ventilation for buildings. Ventilative cooling systems. Design is classified in these ICS categories:

• 91.140.30 Ventilation and air-conditioning systems

This document gives guidance to the design of ventilative cooling systems while referring to relevant standards to ensure coherence and avoiding overlapping. In this document different design approaches for use of natural, mechanical or hybrid ventilative cooling can be found, starting at the feasibility phase before going into the design phase. In addition, this document gives guidance on where to find additional information on the design, calculation and maintenance of such systems. This document is applicable to buildings specified according to the thermal indoor environmental aspects used for human occupancy where production processes don’t have a major impact on the indoor environmental quality. This document is applicable to residential and non-residential buildings. This document applies to all types of buildings: new and retrofit, residential and non-residential. This document is applicable to: - mechanical ventilative cooling - natural ventilative cooling - hybrid ventilative cooling - airing as a supplement to ventilative cooling specifically relevant during e.g. power failures - supplementary free cooling as a supplement to ventilative cooling The design of supplementary free cooling systems and active cooling systems are not part of the normative part of the document. However, the interface between ventilative cooling systems and supplementary free cooling systems as well as the interface between ventilative cooling and active cooling systems are mentioned informatively. Design of ventilative cooling systems commonly considers other aspects like energy use, acoustic, draught, solar gain control, outdoor air quality, user acceptance, burglary and cleaning and maintenance, though these are not covered in detail in this document. This document only covers temperature control. This document does not apply to: - moisture control - waterborne - heat losses.
