The system allows building managers to set temperature guardrails while maintaining resident comfort, reducing energy consumption by up to 25% in early tests. Designed for old buildings with aging boilers, the window units install in hours without electrical upgrades and can participate in grid demand response by intelligently reducing AC load during peak times while preserving comfort. ## Full article daily.dev links to this article rather than hosting it.
