Abstract
Retrofitting older buildings and embedding new building stock with Energy Management Systems (BEMS) is paving the way for smarter energy use and increased wellbeing awareness and initiatives for occupants. BEMS can discover problems related to energy wastage, user comfort and building maintenance. Remote analysis and categorization of the different Heating, Ventilation and Air-Conditioning (HVAC) Terminal Unit (TU) behaviours based on a unique set of features using BEMS data is the main aim of the proposed work. Hence, a novel feature extraction method inspired by the Proportional Integral Derivative (PID) controller response curve to define events from TU data is proposed and applied to multidimensional, realtime data streams remotely retrieved from a building based in the city of London. The feature extraction method executing across different TUs and the feature sets obtained, have been used to identify different TU behaviour patterns. Subsequently, unsupervised machine learning has been employed to investigate automated TU fault detection and diagnosis

| Other | Sustainability is defined as pursuit of environmentally sound development that meets the needs of the present without compromising the future! The theme of the 2017 IEEE Technologies for Sustainability (SusTech) Conference is “Sustainability Futures”. The conference is designed to explore the development and application of science, engineering and technology to promote sustainability. It brings together technologists and scholars from multiple disciplines to hold a dialogue on environmental issues and collaborate on ideas to develop and utilize innovative tools and intelligent systems to address them. The Conference strives to provide attendees the tools, connections and proactive solutions to take their sustainability programs to the next level. It is also an excellent forum to showcase various technologies in development that address sustainability topics. |
