Hygrothermal performance of buildings - Calculation and presentation of climatic data - Part 2: Hourly data for design cooling load
适用范围：This part of ISO 15927 gives the definition and specifies methods of calculation and presentation of themonthly external design climate to be used in determining the design cooling load of buildings and the designof air conditioning systems.Depending on the building type, a range of parameters can be used to define the individual days of hourly orthree-hourly data in each calendar month that impose a cooling load likely to be exceeded on 5 %, 2 % and1% of days.The parameters that are always used in the selection are dry-bulb temperature and total global solarirradiation (or sunshine hours). The daily swing in dry-bulb temperature, dewpoint temperature and windspeed and any other parameters relevant to particular buildings may also be included.Hourly peak values of dry-bulb temperature and dewpoint temperature are needed for the design of airconditioning systems.
