This European Standard is not applicable to:
-   Buildings with kitchens where cooking is not for immediate use
-   Buildings with automatic windows (or openings)
-   Buildings with industry process ventilation.
The definition of ventilation and airtightness requirements (as indoor air quality, heating and cooling, safety, fire protection…) is not covered by this standard.
The following information can be found in other standards and technical reports:

Energijske lastnosti stavb - Prezračevanje stavb - 7. del: Metode za izračun in določanje količine zraka v stavbah, vključno z infiltracijo - Modul M5-5

Ta evropski standard opisuje metode za izračun pretoka zraka pri prezračevanju stavb, ki so namenjene za ocenjevanje izračunov energije ter ogrevalne in hladilne obremenitve.
Ta evropski standard se uporablja za stavbe s/z:
– mehanskimi prezračevalnimi sistemi (mehanski izpuh, mehanski dovod ali uravnotežen sistem);
– pasivnimi prezračevalni sistemi za stanovanjske in nizke nestanovanjske stavbe;
– zgorevalnimi napravami;
– okni z ročnim odpiranjem;
– kuhinjami, namenjenimi kuhanju za takojšnjo porabo (vključno z restavracijami).
Ta evropski standard se uporablja za hibridne sisteme, ki združujejo mehanske in pasivne prezračevalne sisteme v stanovanjskih in nizkih nestanovanjskih stavbah.
Ta evropski standard se nanaša na stavbe, ki so manjše od 100 m in sobe, v katerih je navpična temperaturna razlika zraka nižja od 15 K.
V standardu so navedeni naslednji rezultati:
– pretok zraka na vstopu ali izstopu iz območja prezračevanja;
– pretok zraka, ki ga mehanski prezračevalni sistem, če je nameščen, zahteva za porazdelitev zraka.
Ta evropski standard se ne uporablja za:
– stavbe s kuhinjami, ki niso namenjene kuhanju za takojšnjo porabo;
– stavbe z avtomatiziranimi okni (ali odprtinami);
– stavbe s prezračevanjem industrijskih procesov.
Ta standard ne zajema opredelitve zahtev za prezračevanje in zračno tesnost (npr. kakovost zraka v zaprtih prostorih, hlajenje in ogrevanje, varnost, požarna zaščita ...).
Naslednje informacije so na voljo v drugih standardih in tehničnih poročilih:

This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 2017, and conflicting national standards shall be withdrawn at the latest by December 2017. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN shall not be held responsible for identifying any or all such patent rights. This standard has been produced to meet the requirements of Directive 2010/31/EU 19 May 2010 on the energy performance of buildings (recast), referred to as “recast EPDB”. This document supersedes EN 15242:2007.

This document was produced to meet the requirements of Directive 2002/91/EC 16 December 2002 on energy performance of buildings referred to as “EPBD”. The revision for inclusion in the second mandate package was performed by CEN/ TC 156/ WG 21. The revision includes the following changes: — rearrangement of content versus EN 15242:2007, in order to better fit in the modular structure given in EN ISO 52000-1. This document is restricted to emission and control of the ventilation air flow rates (M5-5); — clarification of possibility to use 2 methods to calculate the airflow rates: method 1 based on detailed building characteristics; and method 2 using a statistical approach complying with specific rules; — in method 1, addition of several options for the calculation of the airflow rates through windows, including cross-ventilation; — in method 1, calculation of the airflow rates using mass balance only; — formatting according to the new rules set in prCEN/TS 16629; and — consideration of ISO/TC 205 work performed in the meantime. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association. SIST EN 16798-7:2018
