Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for displaying facility information, such as HVAC system status, are limited in conveying operational awareness and are not effectively accessible to non-technical users.
Innovation Solution
A method utilizing scalable resolution-independent vector images, associated with data points in a building management system, to render floorplan data with graphical characteristics determined by temperature values and setpoints, enabling real-time visualization and navigation, and allowing users to share video data representing historical states of the facility's conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If layer-based temperature information overlay is used on floorplan renderings, then temperature data can be displayed, but the level of operational awareness conveyed is limited
Solution Approach 1:
The patent applies color-coded visual indicators to represent different operational states of HVAC equipment. Temperature data is not merely overlaid but transformed into intuitive color gradients and heat maps that immediately convey operational awareness to users, resolving the limitation of traditional overlay methods.
Solution Approach 2:
The patent transitions from two-dimensional floorplan overlays to three-dimensional building models with spatial temperature distribution. This dimensional enhancement allows comprehensive operational awareness while maintaining visual clarity through interactive exploration capabilities.
2Loss of information
If detailed HVAC performance data is displayed, then operational awareness is improved, but accessibility to non-technical users deteriorates
Solution Approach 1:
The patent implements contextual information presentation where technical details are displayed locally at equipment locations on the 3D model. Non-technical users see simplified visual indicators at glance, while detailed performance data is available on-demand through interactive elements, balancing accessibility with information completeness.
Solution Approach 2:
The system dynamically adapts information presentation based on user interaction. Static visual indicators provide immediate understanding for non-technical users, while interactive exploration reveals detailed HVAC performance data, making the system accessible to all user levels without compromise.
3Loss of information
If real-time temperature monitoring is implemented, then operational awareness is enhanced, but data processing requirements increase
Solution Approach 1:
The patent extracts and visualizes only the most critical temperature information at strategic locations within the 3D building model. Rather than processing and displaying all raw sensor data, the system selectively presents essential real-time status through optimized visual indicators, reducing processing energy while maintaining operational awareness.

AI summary
The present disclosure relates to methods for displaying facility information. One such method includes causing a client terminal to render on-screen floorplan data at a desired position and resolution, wherein the floorplan data is defined by a plurality of scalable resolution independent vector images, each resolution independent vector image representing a physical space in a facility. As set of rules are executed thereby to apply determined visual characteristics to one or more of the vector images, wherein each of the one or more vector images is associated with a data point in a building management system, and wherein for a given vector image the set of rules defines a relationship between observed data point values and visual characteristics to be displayed.
