To enhance the quality of their education, schools have recently expanded the use of new electronic devices for the benefit of teaching and research. The amount of electrical equipment on campus has recently soared, and the total power demand increases year by year. Many schools are even fined for their overuse of electricity—mostly due to the use of air-conditioning. For example every day during a university’s semester, tens of thousands of students, faculty, and staff use dozens of buildings either for classes or administrative affairs. To maintain the regular operation of the school, electricity is the main resource. Therefore, the amount of money needed to pay electricity bills every year is stunningly huge.
According to statistics, if energy conservation was properly carried out , the campus could save 15 to 20 per cent of electricity. In this way, not only energy can be more efficiently used, but also electricity bills can be reduced. With the help of the Internet, it is no longer necessary to manage power on a site-by-site basis. The Internet not only enables a power management system that monitors and improves energy use across the campus, but also ensures higher energy efficiency. Therefore, as more and more schools commit themselves to saving energy and reducing carbon emissions, power monitoring systems have become essential for energy management.
To conserve energy in schools, Advantech provides a web-based power monitoring system that consists of WebAccess software and a BAS-3520 DDC controller. With Advantech WebAccess installed in power monitoring stations, operators can use a human machine interface to monitor the power consumption data of every device on site. They can then compare and analyze the data so as to take appropriate actions to reduce power consumption whenever necessary. To prevent data loss during transmission, should the Internet not be available, the BAS-3520 controller automatically connects to a digital multimeter so that the data can be temporarily stored on a local computer. As soon as the Internet resumes, data is transmitted to the monitoring center. This way, all monitoring data can be preserved. Not only that, making full use of the advantages provided by the Internet, Advantech establishes a system that facilitates the display and searching of real-time power consumption data, enabling schools to understand the power use of every building and therefore making it easier to plan and implement energy conservation measures.
