At the heart of the 75Fahrenheit system are its Smart Algorithms and Progress® Kinvey™. Wireless zone controllers and air supply sensors continuously collect building and system parameters and send them to the Central Control Unit (CCU)—an Android mobile device and application. The CCU aggregates this minute-tominute time series information and pushes it to the Kinvey serverless backend data store for processing.
Using APIs, the Kinvey data store pushes this data to a Node.js application running on-site in 75F’s data center that processes all these inputs and creates the optimal control strategy. The optimal control strategy is sent back to the CCU, which then proactively commands the smart dampers to the required positions and turns on the HVAC equipment during the day.
By providing targeted, real-time control over the temperature zones within the building, this closed-loop feedback system allows the 75Fahrenheit system to provide optimal thermal comfort, while cutting energy usage.
The 75Fahrenheit application takes advantage of several Kinvey features, including:
• Kinvey Android client libraries for online/offline caching, push notifications and integration with business logic and engagement features
• User identity management, to support multiple levels of user types with different levels of access
• Kinvey Data Store, to manage time series data generated by smart devices
• Kinvey File Store, to backup device files and settings in case devices need to be rebooted or replaced
• Kinvey Business Logic, to integrate with the Node.js data analysis application
• Kinvey Push Notifications, to deliver realtime alerts, notifications and setting change information
