Device arrangement apparatus and device arrangement method

A device arrangement method to be performed by a device arrangement apparatus, the device arrangement method comprising:

• storing past arrangement data of power source or air conditioning devices in a building;
• generating, by the device arrangement apparatus, by referring to an actual arrangement data storage unit storing past arrangement data of a device, device arrangement rules each including a past installation space of the power source or air conditioning devices and relative direction information indicating a relative direction between the power source or air conditioning devices that were arranged in the past installation space;
• inputting, by the device arrangement apparatus, information on a new installation space and current power source or air conditioning devices to be arranged in the new installation space, which is received from a user;
• extracting, by the device arrangement apparatus, from among the device arrangement rules generated in the generating of the device arrangement rules, device arrangement rules each including a pair of the current power source or air conditioning devices among the current power source or air conditioning devices to be arranged in the new installation space input in the inputting;
• and
• calculating, by the device arrangement apparatus, an arrangement position of the pair of the current power source or air conditioning devices among the current power source or air conditioning devices to be arranged in the new installation space based on relative direction information included in one of the device arrangement rules extracted in the extracting of the device arrangement rules and based on dimensions of the pair of the current power source or air conditioning devices among the current power source or air conditioning devices to be arranged in the new installation space input in the inputting.
