Air conditioning control system, air conditioning control method, and recording medium

An air conditioning control system comprising:

• an obtainer that obtains, from each of users that use a predetermined space of a facility, user information related to an attribute of the user;
• a calculator that calculates a target temperature of the predetermined space;
• and
• a controller that so controls air conditioning equipment provided in the predetermined space as to bring a temperature of the predetermined space to the target temperature, wherein
• the calculator:
• calculates a comfortable temperature range for each of the users based on a metabolic rate of the user and a predicted mean vote (PMV), the comfortable temperature range being a temperature range in which the user feels comfortable, the metabolic rate of the user being based on the user information;
• and
• determines, as the target temperature, a temperature that has a small difference from an outside air temperature of the predetermined space, within a range where at least a portion of the comfortable temperature ranges of the users overlap with each other.
