Thermal Behavior

Home I/O includes a simplified heat transfer model which simulates the house thermal behavior. It approximates the phenomena of radiation, convection, and conduction by considering the physical properties of building materials. This model is also affected by weather conditions, geographical coordinates, and disturbances created by airflow between rooms and the exterior.

Since the house thermal behavior is typically a slow phenomenon, it is advisable to use the simulation in accelerated mode.

Weather variables	Effect
Exterior air temperature	Affects the house temperature. Doors and windows play a major role in how the exterior air affects the house temperature.
Wind speed	Wind increases the effect caused by the exterior air temperature.
Wind direction	Rooms facing the wind direction are more affected by the exterior air temperature.
Cloudiness	Decreases the effect of the sun and sky radiation.
Humidity	Alters the dew point, which changes how the exterior air temperature affects the house.
