Event-Driven Building Automation for Occupancy-Based Energy Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for building and space management systems that optimize the use of building amenities and resources by intelligently managing occupancy and environmental conditions in commercial and residential spaces, particularly for scheduled events, to enhance efficiency and energy usage.
Innovation Solution
A building automation system that integrates occupancy sensors, access control, and HVAC systems to dynamically adjust environmental conditions based on event configurations and attendee presence, while optimizing energy efficiency by scheduling events in spaces that are strategically located for residual heating and usage patterns.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If building management systems manually monitor and adjust environmental conditions for each scheduled event, then occupancy and space utilization can be tracked, but energy efficiency and resource optimization are compromised due to lack of real-time automation
Solution Approach 1:
The building management system automatically monitors occupancy via sensors and adjusts environmental conditions (HVAC, lighting) without manual intervention. The system self-regulates based on real-time occupancy data, enabling both efficient space utilization tracking and energy optimization simultaneously.
Solution Approach 2:
The system continuously collects occupancy data from sensors and uses this feedback to dynamically adjust environmental controls. This closed-loop feedback mechanism ensures that energy is optimized based on actual space usage patterns while maintaining accurate occupancy tracking.
2Reliability
If building management systems adjust environmental conditions for all scheduled events regardless of actual occupancy, then event amenities are ensured, but energy waste increases in unoccupied spaces
Solution Approach 1:
The system dynamically adjusts environmental conditions based on real-time occupancy status rather than following fixed schedules. When spaces are occupied, amenities are activated; when unoccupied, systems are reduced or shut off, ensuring reliability only when needed and eliminating energy waste.
Solution Approach 2:
The system changes operational parameters of environmental controls (temperature, lighting levels) based on occupancy detection.occupied spaces receive full amenity service while unoccupied spaces receive reduced service, optimizing the balance between reliability and energy consumption.
3Extent of automation
If occupancy sensors and automated control systems are deployed throughout the building, then real-time occupancy tracking and energy optimization are achieved, but system complexity and implementation cost increase
Solution Approach 1:
The system uses multi-functional sensors that simultaneously track occupancy, monitor environmental conditions, and trigger control actions. This universal approach consolidates multiple functions into integrated components, reducing overall system complexity despite high automation levels.

AI summary
An event automation system controls building management systems (e.g. building automation, access control, and/or security systems of a building) for scheduled events. An occupancy module generates occupancy information for event spaces where events are scheduled via occupancy sensors installed at the event spaces. A building automation module instructs distributed devices of the building management systems to control the environmental settings of the event spaces based on the occupancy information and stored space, attendee, and schedule information. The event automation system also facilitates scheduling the events at event spaces of the building based on configuration information from an event organizer (e.g. invited attendees, start and end times, and activities to be performed at the event), required automation features for the event, location information and exercise preferences for the invited attendees, and/or aggregated usage information for the event spaces.
