An integrated design of energy and indoor environmental quality monitoring system for effective building performance management

Abstract: Understanding the energy consumption pattern in the built environment is invaluable for the evaluation of the sources of energy wastage and the development of strategies for efficient energy management. An integrated monitoring system that can provide high granularity energy consumption and indoor environmental quality (IEQ) data is essential to enable intelligent, customized, and user-friendly energy management systems for end users and help improve building system performance. This paper, therefore, presents an integrated design of an internet of things (IoT)-based embedded, non-invasive, and user-friendly monitoring system for efficient building energy and IEQ management. The hardware unit of the system is comprised of a wireless microcontroller unit, current and voltage sensor, IEQ sensors, and power management unit that enables the acquisition, processing, and telemetering of energy and IEQ data. The software unit is made up of embedded software and a web-based information provision unit that handles real-time data analysis, transmission, and visualization on the web and provides relevant notifications to the end users about energy consumption patterns. The proposed system provides a promising solution for real-time information exchange regarding energy consumption and IEQ for both end-users and managers that will enhance effective building energy and environmental management.
