This part of ISO 15927 specifies two procedures for providing an estimate of the quantity of water likely to impact on a wall of any given orientation. It takes account of topography, local sheltering and the type of building and wall.<\/p>\n
The first method, given in Clause 3 and based on coincident hourly rainfall and wind data, defines a means of calculating<\/p>\n
the annual average index, which influences the moisture content of an absorbent surface, such as masonry, and<\/p>\n<\/li>\n
the spell index, which influences the likelihood of rain penetration through masonry and joints in other walling systems.<\/p>\n<\/li>\n<\/ul>\n
The second method, given in Clause 4 and based on average wind data and a qualitative recording of the presence and intensity of rain (the present weather code for rain), defines a means of calculating the spell length during which an absorbent material such as masonry is moistened, which has a 10 % probability of being exceeded in any year (commonly referred to as having a mean return period of 10 years).<\/p>\n
A comparison between the two methods is given in informative Annex D.<\/p>\n
Procedures are given to correct the results of both methods for topography, local sheltering and the type of building and wall.<\/p>\n
The methods included in this part of ISO 15927 do not apply in<\/p>\n
mountainous areas with sheer cliffs or deep gorges,<\/p>\n<\/li>\n
areas in which more than 25 % of the annual rainfall comes from severe convective storms,<\/p>\n<\/li>\n
areas and periods when a significant proportion of precipitation is made up of snow or hail.<\/p>\n<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
