# Infiltration and ventilation heat load
# Scope: Sensible infiltration heat; no humidity or latent load.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

volume = 100 m^3
changes = 0.5 h^-1
density = 1.2 kg/m^3
heatCapacity = 1005 J/(kg*K)
difference = 20 K

flow := volume*changes [m^3/s]
heat := density*flow*heatCapacity*difference [W]

check infiltration heat budget: heat <= 400 W

scenario alternative: volume = 80 m^3
