REFERENCE STANDARD FOR THE 

VENTILATION OF RESIDENTIAL BUILD

-

INGS 

The concept of air ventilation for confine 

spaces is taken into consideration by sev-

eral standards. 

The 

Standard  EN 12792:2003 

(Ventilation 

for  buildings  –  symbols  terminology  and 

graphical symbols) defines two concepts:

Aeration

: meaning natural ventilation by 

opening a window. 

Ventilation

: meaning the extraction and sup-

ply of air to a space. It is interesting to note 

that the standard talks about “designing” for 

ventilation. 

The 

directive  2002/91/CE

 talks about the 

energy efficiency of buildings and defines 

it as the quantity of energy effectively con-

sumed or that is anticipated to be required 

to satisfy the various needs connected to 

the standard use of a building, including 

amongst others: heating of water, cool-

ing, ventilation and lighting.  The directive 

underlines to take account of the general 

climatic conditions of the internal spaces in 

order to avoid any negative effects due to 

inadequate ventilation.  

Note that it talks about ventilation and not 

aeration, and even the standards that deal 

with the renewal of air always use the term 

renewal and not aeration: opening and 

closing windows is not considered an effec-

tive system for the renewal of air.

How and when to renew is considered in 

EN 15251:2007

 (Criteria for the indoor envi-

ronment including thermal, indoor air quality, 

light and noise), which combines aspects of air 

quality within buildings with energy aspects.

Having said that the air quality in buildings 

depend on numerous parameters (number of 

people, activities carried out, humidity, smoke, 

emissions from furniture and construction ma-

terials, etc.), it is an essential fact that ventila-

tion must be continuous, and acceptable that 

the air renewal rate requirement is variable 

depending on whether the space is occupied 

or not.

If not occupied the air renewal rate is be-

tween 0.05 and 0.1l/s, per m

2

If the space is occupied the same stand-

ard defines different air renewal classes: 

the higher the renewal rate the higher the 

building class. 

I

: High requirement level, recommended 

for spaces occupied by  very sensitive and 

fragile people with special needs, such as 

the handicapped, the sick, very small chil-

dren and the elderly. 

II

: Normal requirement level, to be used for 

new constructions and renovations. 

III

: Acceptable, moderate requirement lev-

el, to be sued for existing buildings.

IV

: Values outside of the criteria for the cat-

egories above. This category might only be 

accepted for a limited part of the year. 

(a): The air renewal ratel expressed in l/s per m

2

 and Vol/h (hourly volume) coincide with a ceiling height of 2.5 m.

(b): The number of occupants of a dwelling can be evaluated from the number of bedrooms. 

 

If there are any national or local requirements these are used. 

Example:

Suppose we have to design an air renewal 

system for an apartment of  S=100m

2

 with 

room heights of h = 2.5m.

As recommended by the standard EN 

15251:2007, if we want to ensure a catego-

ry III, the air renewal rate must be:

S × h × 0.5 = 100 × 2.5 × 0.5 = 125m

3

/h 

if the space is occupied. But if the space is 

not occupied the air renewal rate becomes:

S × 0.05 = 100 × 0.1 = 10l/s = 36m

3

/h
