Smart Energy Management with Edge AI in a COVID-19 World

Edge-AI-Smart-Energy-ManagementSchools and university campuses are looking a little different this back-to-school season than in previous years, due to COVID-19. As many schools and businesses make the transition to hybrid or fully online learning and working, smart building managers and operators must also make the transition to accommodate for sudden occupancy fluctuations -- varying from full classrooms and offices one day, to a completely empty campus and building the next if an outbreak occurs.

Pre-COVID, organizations typically had a routine schedule that building management systems are programmed to follow for e.g. lights and HVAC on from 7:00 a.m. to 5:00 p.m. However, with the varying levels of occupancy on a day-to-day basis as a result of rotating office and class schedules, smart building managers are tasked with the challenge of accommodating irregular schedules and activity. These tasks include ad hoc  schedule enforcement and setting room temperatures and lighting.

Enhance Your Building Management System with Edge AI

Edge AI can be applied to an existing building management system (BMS) or building automation system (BAS) to reduce energy consumption, provide increased occupant comfort, safety, and better utilize building assets and services of critical systems, such as elevators, fire alarms and sprinkler systems.

A smart edge AI-enabled BMS or BAS system can help implement real-time adjustments to schedule variations, prime HVAC systems based on changing conditions, including building occupancy, weather and energy demands. Rather than replacing a current BMS or BAS and implementing entirely new hardware and software, edge AI can provide intelligence to sit on top of and enhance existing systems. As a result, building managers are able to amplify their BMS capabilities in a cost-effective manner. 

Improving Building Energy Efficiencies through Edge AI Platforms

By leveraging an edge AI platform, such as FogHorn Lightning Edge AI, the Edge AI platform can collect data from a multitude of sensors and external sources, for e.g. temperature and occupancy sensors, weather forecasts, and even time-of-day energy rates.  The collected data can be correlated, processed and analyzed with sophisticated machine learning models and AI to automatically determine the optimal start/stop times, heating and cooling profile and  lighting for each zone, room, building or campus. This approach allows smart building managers to capitalize on the most efficient use of energy while ensuring occupancy comfort. 

During this process, edge AI platforms utilize real-time data to react to any changing conditions and make system adjustments immediately, as they happen. This approach results in tremendous savings  and improves overall system efficiencies and results in significant consumption and cost savings over time.

Other types of sensor these  platforms  incorporate include vibration sensors, flow meters and temperature probes, to ensure optimal performance and energy usage of equipment such as the HVAC systems. Managers and operators of such Smart buildings can use these insights to gain better visibility into their system functions and improve operational efficiencies across their facilities. 

Learnings From Smart Energy in a COVID World

Building Management Systems are fairly sophisticated human centric  interconnected systems and subsystems. An Edge AI enabled system  facilitates an intelligent  interplay of such systems that can evolve from smart buildings to smart cities, which is especially critical as our routines and “norms” continue to change on a day-to-day basis. In general such adaptive systems enable an intelligent conservation of energy,  besides financial advantages, this is good for the planet we live in.

Using an Edge AI enabled BMS, a building operator can monitor and manage the behavioral patterns of  the system without having to physically go into the building and rely on the Edge AI intelligence to orchestrate the BMS functions  to automate and optimize energy usage.

COVID-19 has encouraged many building managers to discover the benefits of an edge AI-powered BMS, creating a more agile and efficient smart building ecosystem. The benefits are multifold.  A smart BMS can identify what the contributing factors are for one area of a building using more energy than other areas. This can help formulate appropriate remedial measures, many of which are A.I powered without the need for human involvement.  The learnings from one system can be applied to other building spaces to help maximize efficiency.
