Depressurization occurs when the air pressure
30、inside a house is lower than it is outside.It is more frequent in existing houses after they have been retrofitted and air-sealed.The exterior envelope of many houses is becoming much tighter due to the desire for increased energyefficiency and comfort. Under certain circumstances,there is a possibi
31、lity that combustion products fromfuel-burning equipment will spill into the house, rather than being correctly exhausted to the outdoors. Abuildup of combustion products in the house poses a health risk to the occupants. Other circumstancesthat pose risks include the passage of soil gases such as r
32、adon, and the passage of vehicle-basedor otherpollutants from an attached garage; however this Standard does not give a method to determinedepressurization levels or recommend mitigation strategies for these occurrences.When houses undergo any renovations, the ventilation rate of that house is usual
33、ly reduced and mightno longer be adequate. This Standard describes a method to identify when residential depressurizationcan cause a health risk, and provides solutions to prevent or mitigate the buildup of combustion productsin the house. This Standard is intended for the use of those who sell and
34、install fuel burning appliancesand ventilation equipment, as well as designers, renovators, trades people, building officials, utilities, andhomeowners.The method and solutions are based on the assumption that the fuel burning appliances in the househave been maintained and operated as per the manuf
35、acturers certified instructions.1 Scope1.1This Standard describesthe methods for determining the level of depressurization and solutions tomitigate risk arising from depressurization.1.2This Standard applies to all existing single-family dwelling units contained in detached, semi-detached,and row ho
36、uses equipped with an exhaust device, which havea) a combustion device within the house; orb) an attached garage.1.3This Standard does not provide depressurization level assessment methods or solutions fora) the infiltration of soil gas such as radon;b) the presence of volatile organic compound (VOC
37、) emissions from building materials or contents;c) the presence of mold in houses; ord) the presence of pollutants from other sources, such as stored chemical products.F300-13Residential depressurizationDecember 2013 2013 CSA Group 101.4The requirements of this Standard are expressed in SI (metric)
38、units.1.5In this Standard,“shall” is used to express a requirement, i.e., a provision that the user is obliged tosatisfy in order to comply with the standard; “should” is used to express a recommendation or thatwhich is advised but not required; and “may” is used to express an option or that which i
39、s permissiblewithin the limits of the standard.Notes accompanying clauses do not include requirements or alternative requirements; the purpose of anote accompanying a clause is to separate from the text explanatory or informative material.Notes to tables and figures are considered part of the table
