Description

Building Energy Management System with Remote Control of BIPV The present invention relates to a building energy management system, and more specifically, to a building energy management system capable of remote monitoring and control of a building-integrated photovoltaic power generation system. A Building Energy Management System (BEMS) refers to an integrated system comprising measurement, control, management, and operation that monitors energy usage and provides optimized management solutions to maintain a comfortable indoor environment and manage energy efficiently. BEMS involves installing sensors and measuring equipment on energy-consuming facilities within a building, such as lighting, heating, cooling, ventilation, and gas, enabling the real-time collection of usage data by energy source, including electricity and gas. Based on this collected data, it becomes possible to analyze energy usage patterns and consumption status by purpose and time of day, as well as identify factors causing unnecessary energy waste. Furthermore, it allows for the optimization of energy consumption through the automatic control of heating, cooling, and lighting systems, and enables the management of peak power usage by adjusting the building's load during periods of highest energy consumption. Patent Document 1 discloses an example of such a conventional BEMS system, and FIG. 1 is a configuration diagram thereof. The conventional BEMS system is composed of a data collection unit (1) for verifying the energy usage of a building, an equipment control unit (3) for automatic control targeting various facilities provided inside the building and for verifying the operating status of each facility, a sensor unit (5) for collecting environmental data such as temperature and gas concentration, and an EMI server (7) that collects the collected data and transmits it to an EMS server (9), thereby performing appropriate control for energy saving by synthesizing the energy usage status within the building, the operating status of facilities, and environmental data. In other words, the conventional BEMS has focused on effectively using energy based on the premise of energy input. Meanwhile, as global warming accelerates and carbon neutrality and greenhouse gas reduction become major issues for countries around the world, measures to address this are emerging. Korea has also introduced a zero-energy building certification system at the government level, making certification mandatory for public buildings with a gross floor area of 500㎡ or more and public multi-unit housing with 30 or more households in 2023, and is strengthening standards by making certification of Grade 4 or higher mandatory for public buildings of 17 uses with a gross floor area of 1,000㎡ or more in 2025. The certification standard is to determine the ZEB certification grade based on the higher of the primary energy consumption or the energy self-sufficiency rate. However, since it is difficult to reduce the total annual primary energy consumption per unit area, the trend is moving toward increasing the energy self-sufficiency rate, which is the ratio of primary energy production to primary energy consumption per unit area of a building. Representative methods for increasing energy self-sufficiency include installing solar panels on buildings or incorporating them into parts of buildings. These can be broadly classified into BAPV (Building Applied Photovoltaics) and BIPV (Building Integrated Photovoltaic System). This invention relates to BIPV, which, simply put, is a system that generates electricity within a building by replacing parts of the structure, such as windows or balconies, with solar panels. However, as mentioned above, conventional BEMS have been operated on the premise that electricity or fuel is supplied from an external source, so there is a problem in that monitoring and controlling electricity generated within the building, unlike BIPV, is impossible. Figure 1 is a configuration diagram of a conventional BEMS system.
