Ventilation for buildings - Determining performance criteria for residential ventilation systems

This European Standard sets out criteria to assess the performance of residential ventilation systems (for new, existing and refurbished buildings) which serve single family, multi family and apartment type dwellings throughout the year.
This European Standard specifies ways to determine performance criteria to be used for design levels in regulations and/or standards.
These criteria are meant to be applied to, in particular:
- mechanically ventilated building (mechanical exhaust, mechanical supply or balanced system);
- natural ventilation with stack effect for passive ducts;
- hybrid system switching between mechanical and natural modes;
- windows opening by manual operation for airing or summer comfort issues.
This European Standard considers aspects of hygiene and indoor air quality.
Health risk from exposure to tobacco smoke is excluded from this European Standard.

Lüftung von Gebäuden - Bestimmung von Leistungskriterien für Lüftungssysteme in Wohngebäuden

Dieses Dokument legt Kriterien zur Bewertung der Leistung von Lüftungssystemen (für Neubauten, Bestandsbauten und sanierte Gebäude) fest, die Einfamilien , Mehrfamilien  und Mietswohnhäuser das ge-samte Jahr über versorgen.
Dieses Dokument beschreibt Wege zur Bestimmung von Leistungskriterien, die für die Auslegungsgrade in Vor¬schriften und/oder Normen genutzt werden können.
Diese Kriterien sind vor allem vorgesehen für die Anwendung bei:
   Gebäuden mit maschineller Lüftung (ventilatorgestützte Abluft, ventilatorgestützte Zuluft oder Zu  und Ab¬luft);
   freier Lüftung mit thermischem Auftrieb für Luftschächte;
   Hybridsystemen, die zwischen maschineller und freier Lüftung schalten;
   manuell zu öffnende Fenster, zur Lüftung oder für komfortable Bedingungen im Sommer.
Dieses Dokument berücksichtigt Aspekte der Hygiene und der Raumluftqualität.
Gesundheitsrisiken, die sich aufgrund von Tabakrauch ergeben, sind in diesem Dokument nicht behandelt.

Ventilation des bâtiments - Détermination des critères de performance pour les systèmes de ventilation résidentielle

La présente Norme européenne définit les critères d'évaluation des performances des systèmes de ventilation
résidentielle (dans les bâtiments neufs, existants ou rénovés) équipant les logements unifamiliaux,
multifamiliaux et les appartements tout au long de l'année.
La présente Norme européenne spécifie les manières de déterminer les critères de performance à utiliser
pour les niveaux de conception dans les réglementations et/ou les normes.
Ces critères sont destinés à s'appliquer, en particulier :
⎯ aux bâtiments à ventilation mécanique (rejet mécanique, apport mécanique ou système double flux) ;
⎯ aux bâtiments ventilés par tirage thermique ou ventilation naturelle;
⎯ au système hybride assurant la commutation entre le mode mécanique et le mode naturel ;
⎯ aux fenêtres s'ouvrant à la main pour aérer ou améliorer le confort estival.
La présente Norme européenne tient compte des aspects liés à la santé et à la qualité de l'air intérieur.
Les risques sanitaires liés à l'exposition aux fumées du tabac sont exclus de la présente Norme européenne.

NOTE 2 These pollutants also include those resulting from human occupation such as water vapour and carbon dioxide from respiration. 3.2 specific pollutants group of indoor pollutants which are of short duration, and in specific locations in the dwelling NOTE These pollutants are mainly represented by water vapour, carbon dioxide and odours, whose production is related to specific human activities in the dwelling (such as cooking, washing, bathing). SIST EN 15665:2009

NOTE Requirements can be, for example, "maximum of 100 hours above 70 % in living room", "less than 10 minutes to reach 25 % of initial ", "less than 800 10-6 CO2 (generally named ppm) as an average", "minimum of 8 l/s in toilet", "35 l/s for global ventilation in standard inside/outside conditions". 4 Symbols and units For the purposes of this document, the symbols and units given in EN 12792:2003 apply. 5 Needs for residential ventilation: main issues 5.1 General There shall be adequate means of ventilation provided for the building and its occupants.
5.2 General sources of pollutants The following sources of pollutants influencing the ventilation in dwelling shall be considered:
 Outside environment, such as climate, earth (which can provide radon);
 Human respiration, odours;  Human behaviour, such as cooking, bathing, drying machine, cleaning;  Emissions of building materials and furniture;  Emissions of cleaning material;  Combustion appliance. Each of these sources can produce pollutants.
Depending on the pollutant sources given in 5.2, the following consequences can be observed: a) For the building: risk of condensation, risk of dryness, mould growth, fungi’s, dust mites, interstitial condensation; b) For human health and comfort: carbon monoxide, CO2 level and water vapour, temperature, air velocity, germs, microorganisms, formaldehydes, VOC (volatile organic compounds), “volatile organic compound, odours, noise from outside. 5.4 Expectations about ventilation Considering the pollutant sources and their consequences, the adequate means of ventilation should be provided for one or more of the following purposes: a) Dilution and/or removal of background pollutants such as substances emitted by furnishings and building materials and cleaning materials used in the building, odours, metabolic CO2 and water vapour; b) Dilution and/or removal of specific pollutants fro
