Design and implementation of a cloud-based building energy monitoring system

Abstract

Energy efficiency and renewable energy are said to be the twin pillars of a sustainable energy policy, both of which should be developed simultaneously in order to reduce carbon dioxide emissions. In this thesis, we design and integrate a cloud based energy monitoring system for buildings so that people such as commercial managers or residential building occupants can make policies accordingly regard to improving the efficiency of energy usage. This system consists of three major components: wireless sensor network, embedded Linux gateway and cloud computing component. The wireless sensor network achieves the function of retrieving energy consumption data on the socket level without comprising the existing power supply infrastructure. The embedded Linux gateway reads data from to the wireless sensor network and delivering them to the cloud. The cloud process the raw energy data, store the processed data to a database and displaying the power consumption using a web server for visualization.
