According to one embodiment, a scheduling apparatus sends queries to communication modules (20) in buildings (2) and receives facility information measured at monitor-control points (21) from the communication modules (20). As for each communication module (20), a network address, a waiting time to receive the facility information after sending a query, and a connection with the monitor-control points (21), are stored. When a service request indicating at least one monitor-control point (21) is received, queries each including the network address of a communication module (20) connected with a monitor-control point (21) indicated by the service request, are generated. A priority of each query is decided based on the waiting time corresponding to the communication module (20). Each query is added to a first send queue or a second send queue based on the priority. When queries are sent, a timing to send from the first send queue is same as or earlier than a timing to send from the second send queue.
