Abstract

A ventilation control device is a device for setting a ventilation path in an object space of wind flowing in/out through a plurality of openings between the object space and the outside of the building. The plurality of openings is disposed in a building. An air conditioner performs air-conditioning in the building. The ventilation control device includes: a ventilation-path setting unit; and an output unit. The ventilation-path setting unit sets the ventilation path so that a ventilation path in the object space, in a state in which the air conditioner operates, differs from a path of wind sent from the air conditioner. The output unit outputs path information indicating the ventilation path set by the ventilation-path setting unit.
