Daylighting
These are the standards in SynC Standards that cover Daylighting. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide, with the standards each is verified against. All of it is written and maintained by SynC, free to read without an account, and published under CC BY 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Standards
- Lighting Controls
The interior lighting control system of a commercial, institutional, or industrial building: the occupancy and vacancy sensors, daylight sensors, time schedules, manual control stations, relay panels, lighting contactors, lighting-control panelboards, room controllers, networked and luminaire-level control systems, and the management software that together decide when each luminaire is on, off, or at an intermediate level. Covers the control architecture and its network, the control signal and protocol delivered to the luminaire driver and the minimum light level the system commands, occupancy and vacancy sensing, daylight-responsive control, time scheduling and override, manual control, branch-circuit switching equipment, automatic receptacle control, demand-responsive control, the interfaces to the building automation system, motorized shades, and other building systems, the UL 924 override device that returns a controlled egress luminaire to full output, the low-voltage control wiring, the documented sequences of operation, startup, programming, functional testing, training, warranty, and spares.
- Window Treatments
Interior window treatments installed for glare control, solar heat control, daylight management, privacy, and room darkening in commercial, institutional, and light-industrial buildings. Covers manual and motorized roller shades with solar screen, room-darkening, and blackout fabrics, dual-roller assemblies carrying two shades on one mounting, and draperies on track systems. Addresses fabric composition, openness factor and solar optical properties, fire performance under NFPA 701 and ASTM E84, low-emitting certification, lightfastness, fungal and antimicrobial performance, roller tube and bracket hardware, fascia and pocket concealment, hembars, manual clutch operation and the cord retention provisions of ANSI/WCMA A100.1, motorized operation and its power, listing, control, and integration, mounting condition and light gap, perimeter light-control channels, accessible operation, field testing, installation, warranty, and spare parts.
