# Infiltration ![](/files/-MihpfXF39rzJRWhXDLG) ![](/files/-MihpeMdC4BezjVjbQIt) - [\[source code\]](https://github.com/ladybug-tools/honeybee-grasshopper-energy/blob/master/honeybee_grasshopper_energy/src//HB%20Infiltration.py) Create an Infiltration object that can be used to create a ProgramType or be assigned directly to a Room. ## Inputs * **name** Text to set the name for the Infiltration and to be incorporated into a unique Infiltration identifier. If None, a unique name will be generated. * **flow\_per\_ext\_area \[Required]** A numerical value for the intensity of infiltration in m3/s per square meter of exterior surface area. Typical values for this property are as follows (note all values are at typical building pressures of \~4 Pa): * 0.0001 (m3/s per m2 facade) - Tight building * 0.0003 (m3/s per m2 facade) - Average building * 0.0006 (m3/s per m2 facade) - Leaky building * **schedule** A fractional schedule for the infiltration over the course of the year. The fractional values will get multiplied by the flow\_per\_exterior\_area to yield a complete infiltration profile. ## Outputs * **infil** An Infiltration object that can be used to create a ProgramType or be assigned directly to a Room. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs.ladybug.tools/hb-energy-primer/components/3_loads/infiltration.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
