Subsequently, on the basis of the restricted power amount of the building and the predicted power consumption, the building power management device obtains a surplus power amount of the building 2, and obtains, from users of the tenants 3a-3c, purchase desire information indicating desire of purchase of at least one part of the surplus power amount. Then, on the basis of the purchase desire information and the surplus power amount, the building power management device updates the restricted power amount of the tenants 3a-3c relating to the purchase desire information.;COPYRIGHT: (C)2013,JPO&INPIT
