SOURCE-SENSIBLESOURCE-LATENTINF-SCHEDULEINF-METHODis the fraction of SOURCE-BTU/HR (after being multiplied bythe hourly fractional value in SOURCE-SCHEDULE) that isadded to the space energy balance in the form of sensibleheat. The sum of SOURCE-SENSIBLE and SOURCE-LATENT must notexceed 1.00 and is likely less than 1.00 since all suchenergy is not necessarily added to the space load.is the fraction of SOURCE-BTU/HR (after being multiplied bythe hourly fractional values in SOURCE-SCHEDULE), if any,that is added to the space energy balance in the form oflatent heat.

Theschedule should contain values that modify the calculatedinfiltration values. A value of 1 would leave the infiltrationvalues unmodified night and day, year round. Anyvalue below 1.0 would represent reduction of infiltrationsuch as that caused by pressurization from a supply fan.Any value above 1.0 would represent an increase in infiltrationsuch as that caused by an exhaust fan, open window, oropen door. If the INF-SCHEDULE is not input, but the AIR­CHANGES/HR is, the schedule will default to one for allhours, and the full AIR-CHANGES/HR will be simulated for all24 hours.Ordinarily, INF-SCHEDULE should not be used with the CRACKor RESIDENTIAL method of infiltration because the sChedulewill distort wind information from the weather tape.Input for this keyword is the code-word that identifies themethod used to calculate infiltration for the space.Air-change method calculations are made with and/or withoutwind velocity correction, depending upon the code-wordchosen here and the keyword used to enter the value forinfi ltrat ion.MethodNo-infiltrationAir-changeCrackResidentialCode-WordNONEAIR-CHANGECRACKRESIDENTIALThe use of infiltration-related keywords for different typesof calculation methods is summarized in the following table.111. 49 (Revised 5/81)
