Sky-camera-driven integrated control linking real-time solar data to shading, glazing, lighting, and HVAC for circadian alignment.
A vendor-neutral control architecture that uses sky imagery to continuously derive colour temperature and solar position, then coordinates electrochromic glazing, motorized shading, tunable lighting, and HVAC setpoints to maintain indoor circadian alignment and visual comfort. It addresses fragmentation in building environmental controls—where shading, lighting, and climate operate independently and often counter to occupant sleep–wake physiology. The system treats circadian entrainment as a primary control objective alongside thermal and visual comfort.
This patented control architecture uses a sky-facing camera to continuously derive colour temperature and solar geometry, then coordinates electrochromic glazing, motorized shading, tunable lighting, and HVAC setpoints around a single primary objective — circadian entrainment — rather than treating these building systems as independent controls that happen to share a floor plate. Unifying those historically siloed systems around a biologically grounded control target addresses a documented occupant health problem: indoor light-spectrum misalignment with circadian phase degrades sleep, alertness, and metabolic markers, and most buildings make no attempt to manage it. The record is claimed with no provided evidence, and both critical risks are present simultaneously: no independent peer-reviewed field validation exists, and no commercial product or installed base has been identified — patent collateral assignments in 2024–25 indicate financing activity, not sales. The hardware prerequisite is capital-intensive even in new-build: electrochromic glass, motorized shading, and tunable LED systems must all be present and interoperable, and the sky camera degrades in overcast or polluted conditions that are common in Northern European climates. Occupant override conflicts — screen work, meeting lighting preferences, hotdesking — must be arbitrated by a control logic that is proprietary and untested at scale. This is an interesting systems-integration thesis; a specifier should wait for a documented commissioned installation with measured occupant outcomes before treating it as anything more.
Patent family (US10619415, US11060351, US11473371) granted 2020–2022 with provisionals to 2004, confirming intellectual property maturity. No peer-reviewed performance studies, case studies, or product datasheet located. No company website, product pages, or installation references in public domain. Collateral assignment filings through 2024–25 suggest debt/equity financing but no evidence of commercial launch or pilot deployment. Sub-technologies (electrochromic windows, circadian LED systems) are mature and available separately from other vendors; the novel claim is closed-loop sky-camera integration, which remains undemonstrated. Absence of evidence is not evidence of absence, but lack of any third-party validation or deployment narrative is a material gap for a system claiming coordinated building control.
