Building information model-based building energy management apparatus and method

Abstract

Disclosed herein is a building energy management apparatus and method. The building energy management apparatus includes a Building Information Model (BIM) analysis unit for receiving and parsing BIM data and then analyzing BIM objects. A building energy object extraction unit extracts building energy objects related to building energy from the BIM objects. A building energy object database (DB) stores a building energy object data into a DB by arranging the building energy objects. A building energy management unit manages energy of a building based on the building energy object data. Accordingly, the present invention provides technology for extracting and managing objects of a building related to the energy of the building based on a BIM, thus efficiently managing building energy.
