Also, there is relatively limited knowledge a
22、bout the basis for ventilation flow rates. Airflow rates are however probably the easiest way to express ventilation requirements. Nevertheless it is worthwhile to consider in a more detailed way the influence of the dilution due to air change on human exposure, in order to understand the ventilatio
23、n requirements expressed in terms of flow rates. Figure 1 explains the process from pollutant to health risk. This European Standard does not deal with health effects, health risks (linked to noise, tobacco), dose and energy impact. This European Standard is not intended to design and/or dimension a
24、 ventilation system. This European Standard is intended to support any regulation or standard. This European Standard is intended to give guidance to those with responsibility for producing requirements and standards for residential ventilation systems. It is recommended that future revisions of rel
25、evant regulations and standards should consider the content of this European Standard.

26、 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 r
27、egulations 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; w
28、indows 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. 2 Normative references The following referenced documents are indisp

31、r pollutants which are continuous and diffuse NOTE 1 These pollutants are represented by materials, furnishings and products used in the dwelling. NOTE 2 These pollutants also include those resulting from human occupation such as water vapour and carbon dioxide from respiration. 3.2 specific polluta
32、nts 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).

NOTE 2 R
34、elative humidity, odours, CO2are examples of parameters. 3.4 criteria way (method) to express the required performance NOTE Criteria can be, for example, numbers of hours above 70 % RH in living room calculated on a standard week basis, number of minutes to reach 25 % of the initial pollution concen
35、tration based on a standard pollutant emission in a toilet, average level of CO2above outside in bedroom on a 10 hours night with two standard persons. 3.5 requirement level of required performance NOTE Requirements can be, for example, “maximum of 100 hours above 70 % in living room“, “less than 10
36、 minutes to reach 25 % of initial “, “less than 800 10-6CO2(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 ap
37、ply. 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 envir
38、onment, 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.

40、g: risk of condensation, risk of dryness, mould growth, fungis, dust mites, interstitial condensation; b) For human health and comfort: carbon monoxide, CO2level and water vapour, temperature, air velocity, germs, microorganisms, formaldehydes, VOC (volatile organic compounds), “volatile organic com
41、pound, 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 emitt
42、ed by furnishings and building materials and cleaning materials used in the building, odours, metabolic CO2and water vapour; b) Dilution and/or removal of specific pollutants from identifiable local sources such as toilet odours, cooking odours, water vapour from cooking or bathing, combustion produ
43、cts; c) Provision of outdoor air for occupants; d) Provision of control of temperature effects (over heating and draught); e) Provision of air for combustion appliances. All these purposes shall be considered with regard to the health and comfort of the occupants and integrity of the building. NOTE
44、1 Ventilation is primarily concerned with the first three purposes (a) to c) but it is linked to the last two (d and e). NOTE 2 When providing ventilation, other aspects of performance including thermal comfort, durability, fire safety, noise and energy use should be considered. 6 General approach 6
45、.1 Questions, assumptions and way of proceeding Before designing a ventilation system, the people involved in regulations and/or standards shall answer lots of questions and assumptions that have to be taken into account for calculation. The result of this calculation can be expressed by a continuou
46、s explicit airflow rate (e.g. mechanical ventilation with constant airflow rate) or an equivalent airflow in terms of air quality according to conventional assumptions applicable in each country (e.g. Technical Approvals). The following way of proceeding shall be used in order to determine airflow r
47、ates (see Figure 2): a) Step 1: verify if there is any applicable regulation (health, fire protection, noise, gas, etc.) in the country that leads to certain limit in airflows; b) Step 2: identify the parameters which are taken into account or which are considered as relevant; c) Step 3: at this ste
48、p of the procedure, take into account the 3 following points: Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 01/04/2010 08:52, Uncontrolled Copy, (c) BSIBS EN 15665:2009EN 15665:2009 (E) 8 1) for each parameter, a detailed description shall be made of the nature, sources, distribution and ti
49、me dependence; 2) for each parameter, the appropriate criteria shall be chosen as described in Clause 7; 3) assumptions for buildings, ventilation systems, outdoor conditions and occupancy patterns shall be described corresponding to the table at the chosen level described in 6.2; d) Step 4: use the appropriate calculation method able to handle the chosen criteria and assumptions; e) Step 5:
