Switchable Window API Integration for Multi-System Building Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart window systems lack sophisticated control and monitoring capabilities, requiring improved techniques for managing interacting building systems as they become more widely deployed.
Innovation Solution
A window control system configured to communicate via an API with other systems like HVAC, lighting, and home appliance control systems, enabling data exchange and coordinated control of optically switchable windows, allowing for advanced management and optimization of building environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If smart window systems are widely deployed, then building management capabilities are improved, but system complexity increases
Solution Approach 1:
The system is divided into independent controllable units (individual windows or window groups) that can be managed separately through the building management system, allowing scalable deployment without overwhelming complexity
Solution Approach 2:
An API interface acts as an intermediary layer between the window control system and other building systems (HVAC, lighting, security), standardizing communications and reducing overall system complexity through modular integration
2Productivity
If multiple systems interact with smart windows, then building optimization is improved, but control complexity increases
Solution Approach 1:
The window control system is designed to perform multiple functions (optical control, energy management, integration with HVAC/lighting/security systems) through a single unified platform, reducing the need for separate control mechanisms for each function
Solution Approach 2:
The system optimizes building performance by dynamically changing operational parameters (window optical state, timing of transitions, coordination with other systems) based on environmental conditions and building needs

AI summary
Disclosed are platforms for communicating among one or more otherwise independent systems involved in controlling functions of buildings or other sites having switchable optical devices deployed therein. Such independent systems include a window control system and one or more other independent systems such as systems that control residential home products (e.g., thermostats, smoke alarms, etc.), HVAC systems, security systems, lighting control systems, and the like. Together the systems control and/or monitor multiple features and/or products, including switchable windows and other infrastructure of a site, which may be a commercial, residential, or public site.
