Building Energy Data Model With Bidirectional Timeseries Views
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Building management systems (BMS) face delays in data presentation due to the need for raw timeseries data to be retrieved and processed in response to requests, leading to inefficient data visualization and management of building energy data.
Innovation Solution
A building energy management system that includes a data collector, data platform services, and an energy management application, which processes raw data samples to generate optimized timeseries data and provides an ad hoc dashboard with interactive visualization options, enabling real-time data analysis and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If raw timeseries data is stored in a relational database without significant organization or processing at the time of data collection, then data storage simplicity is improved, but data presentation speed deteriorates due to processing delays at query time
Solution Approach 1:
The patent pre-processes and organizes raw timeseries data into structured formats with metadata (such as data types, units, descriptions) at the time of data collection rather than waiting until query time. This preliminary organization enables faster data retrieval and presentation while maintaining storage efficiency through standardized data structures.
2Device complexity
If applications are responsible for retrieving and processing raw timeseries data to generate views, then system complexity is reduced, but data presentation efficiency deteriorates due to processing delays
Solution Approach 1:
The patent introduces an intermediary data structure layer between raw data collection and application processing. This intermediary structure includes organized timeseries data with embedded metadata that bridges the gap between simple storage and efficient processing, allowing applications to quickly generate views without extensive processing while maintaining manageable system complexity.
Data Source
AI summary
A building energy management includes building equipment, one or more data platform services, a timeseries database, and an energy management application. The building equipment operate to monitor and control a variable and provide raw data samples of a data point associated with the variable. The timeseries database stores a plurality of timeseries associated with the data point. The plurality of timeseries include a timeseries of the raw data samples and the one or more optimized data timeseries generated by the data platform services based on the raw data timeseries. The energy management application generates an ad hoc dashboard including a widget and associates the widget with the data point. The widget displays a graphical visualization of the plurality of timeseries associated with the data point and includes interactive user interface options for switching between the plurality of timeseries associated with the data point.
