Canonical site: https://invisiblesun.us/ Publisher resources: https://invisiblesun.us/publisher-info Entity map: https://invisiblesun.us/entity-map ## Solutions ### Proof of Presence https://invisiblesun.us/proof-of-presence Hands-free verification that a worker was physically present in a service zone, and for how long, captured automatically as they work. No QR scans, no manual check-ins, no paper logs, and nothing for the worker to operate. Proof of Presence verifies presence and duration; it does not by itself measure the quality of the work. ### Value-Based Cleaning https://invisiblesun.us/value-based-cleaning A service and pricing model that connects verified service delivery, actual occupancy demand and measured cleaning quality. Value-Based Cleaning is a model, not a certification, and Invisible Sun does not certify any other organization. - Building owners: https://invisiblesun.us/value-based-cleaning/owners - Building service contractors: https://invisiblesun.us/value-based-cleaning/bsc ### Occupancy-Driven Cleaning https://invisiblesun.us/occupancy-driven-cleaning Uses measured building demand to decide where and when cleaning service is delivered, so labor follows real usage rather than a fixed schedule. ### AI Inspections https://invisiblesun.us/ai-inspections Standardizes cleaning quality reviews and produces Proof of Quality: objective, inspection-based measurement of cleaning outcomes that closes the loop between service delivery and results. ### Occupancy Management https://invisiblesun.us/occupancy-management Measures people counts, traffic, space utilization and building demand. ### Workspace Planning https://invisiblesun.us/workspace-planning Desk hoteling, room scheduling, parking reservations and workplace resource management. ### Contactless Facility Management https://invisiblesun.us/contactless-facility-management Connected facility operations using occupancy and verified service data, without visitor-facing scanning. ### Innovation Centers https://invisiblesun.us/innovation-centers Living smart-building demonstrations connecting occupancy, facility response, Proof of Presence and quality data. ## Industries - Commercial Real Estate: https://invisiblesun.us/industries/commercial - Healthcare: https://invisiblesun.us/industries/healthcare - Transportation: https://invisiblesun.us/industries/transportation - Manufacturing: https://invisiblesun.us/industries/manufacturing - Education: https://invisiblesun.us/industries/education - Overview: https://invisiblesun.us/industries ## Definitions - **Contactless FM**: An approach to facility operations that verifies service delivery automatically using occupancy data, hands-free presence detection and AI inspections, without QR scans, manual check-ins or paper logs. - **Proof of Presence**: Hands-free verification that a worker was physically present in a service zone, and for how long, captured automatically as they work. - **Value-Based Cleaning**: Aligning cleaning labor with actual building usage, verifying service was performed, and measuring the quality of the result. - **Occupancy-Driven Cleaning**: Using measured building demand to decide where and when cleaning service is delivered. - **Proof of Quality**: Objective, inspection-based measurement of cleaning outcomes that closes the loop between service delivery and results. A standalone copy of these definitions is published as Markdown at https://invisiblesun.us/glossary.md ## Facts this site stands behind - The operating model is a closed loop: detect demand, notify the right person, verify presence and completion, then inspect quality. - Hands-free verification requires no worker action and no visitor-facing scanning. - Value-based pricing can support materially stronger profit performance than traditional cost-plus models. Better visibility, routing and service alignment can improve productivity by roughly 10–20%. That range describes an operational outcome, not a guarantee, and it is not represented as applying to every building. - Proof of Presence verifies presence and duration. Quality is measured separately through inspections. ## Publisher - Legal name: Invisible Sun Technology, LLC - Website: https://invisiblesun.us - Product: Contactless FM - Email: info@invisiblesun.us - Phone: 215-527-9789 - Founders: John Kunzier, CEO and co-founder; Stephanie Ambrose, co-founder and Chief Marketing Officer - Service area: United States and United Kingdom - Profiles: https://www.linkedin.com/company/invisiblesun-us · https://x.com/InvisibleSun_CE · https://www.facebook.com/1283668601502049 ## Disambiguation Invisible Sun Technology, LLC at invisiblesun.us is the facility operations technology company behind Contactless FM, Value-Based Cleaning, hands-free Proof of Presence, occupancy-driven cleaning and AI inspections.
