Energy code compliance for a New York City office lighting retrofit is the registered design professional's responsibility on paper — they document the controls narrative and file it — but the integrator is the party that actually selects, commissions, and proves out the occupancy sensing, daylight response, and automatic shutoff hardware that narrative describes. A wireless lighting-control platform can usually satisfy those code functions in a space that stays occupied during construction, because wireless retrofit hardware is built specifically to avoid pulling new control wiring through finished ceilings and walls. The tenant, architect, and integrator still need to agree early on which party is answering code questions, because that scope line is often assumed rather than written down.
What does the energy code actually require from lighting controls?
Energy codes that apply to NYC office fit-outs generally require three control functions in most spaces: automatic shutoff when a space is unoccupied, daylight-responsive dimming or switching near perimeter glass, and some form of scheduling or demand response at the building or floor level. These are control functions, not a mandate for a specific product or wiring topology — which is why both wired and wireless systems can be specified to meet them, provided the controls narrative documents how each function is achieved in each space type.
A retrofit project layered onto an existing building also has to sit alongside whatever lighting-system and carbon-reporting obligations already apply to that building at the landlord level. Those building-wide obligations are separate from the tenant-space code questions above, and a design team should confirm with the design professional of record which filings cover the tenant's floor versus the base building — that division of responsibility is worth settling explicitly rather than assuming it is covered by someone else's permit.
Can wireless controls satisfy code in an occupied office?
Yes, in principle, because wireless lighting-control systems are explicitly built to add control functions to existing spaces without extensive new wiring. Lutron describes its Vive wireless platform as using Clear Connect wireless technology specifically to transform a building "one step at a time, or as space needs change," addressing lighting retrofits that would otherwise require disruptive new wiring in occupied spaces, and estimates Vive installs up to 70 percent faster than a wired system (Wireless Lighting Control from Lutron Provides Commercial Building Solution). The same source notes Vive is designed for commercial office spaces among other space types and integrates via BACnet with building and energy management systems, which is relevant if the lighting controls need to report into a base-building BMS for energy or carbon documentation.
Crestron takes a similar approach with its Zūm Wireless lighting line, which uses mesh networking to connect devices across a building or campus without requiring Ethernet cabling to every fixture (Zum Lighting Control Systems). Crestron's Zūm Mesh wireless battery-powered occupancy and vacancy sensors pair with an AV Bridge module that lets those sensors feed a Crestron (or third-party) control system over RS-232 or USB, so the occupancy data a code narrative relies on can also drive other room functions like AV presentation state (ZUMMESH-AVBRIDGE). That same product page notes the Zūm Mesh network is designed to operate within a single room and that battery-powered devices function as leaf nodes rather than routing nodes — a detail worth confirming against your floor plan before committing to an all-wireless layout, since networks built mostly from battery devices may need additional AC-powered routing nodes to close coverage gaps.
Whichever platform is selected, ask your contractor or electrical engineer whether the wireless system's sensor placement and mesh coverage have been verified for your specific floor plate, and whether any BACnet or similar reporting path needs to be confirmed in writing before the controls narrative is filed.
Who actually signs off on the controls narrative?
The registered design professional or electrical engineer of record is typically the party who documents the controls narrative and carries responsibility for the filing that tells the city a space meets code. The integrator's role is to execute the control layer to that narrative's specifications — selecting hardware, commissioning sensors and daylight zones, and verifying the system behaves as documented. It is worth confirming in writing, before work starts, exactly where the design professional's sign-off responsibility ends and the integrator's commissioning responsibility begins, since both parties can otherwise assume the other is covering a gap.
Cave Group designs commercial lighting control around Lutron and Crestron platforms for offices, conference rooms, and other commercial spaces, and coordinates directly with IT and design teams on network segmentation and BMS reporting for those systems — see the commercial page for the full capability set.

Frequently asked questions
Does a wireless lighting retrofit avoid all new wiring in an occupied office?
Not entirely. Wireless platforms like Vive and Zūm Wireless are designed to avoid pulling new low-voltage control wiring to switches and sensors, which is the disruptive part of a retrofit in an occupied space, but line-voltage power to fixtures and any AC-powered routing nodes still need their own wiring path.
Can a wireless lighting system report into a building management system?
Yes. Lutron's Vive wireless hub integrates via BACnet with building and energy management, HVAC, IT, and AV systems, which is the typical path for reporting occupancy and energy data up to a base-building BMS.
Who is responsible if the lighting controls don't actually meet code after installation?
The registered design professional or electrical engineer of record owns the controls narrative and filing, but the integrator is responsible for commissioning the system to match that narrative. Confirming this division in the project contract, rather than assuming it, avoids disputes if an inspector flags a gap.
Does occupancy sensor hardware differ between a single room and a whole floor?
It can. Crestron notes its Zūm Mesh wireless network is designed to operate within a single room, with AC-powered devices acting as routing nodes and battery-powered devices acting as leaf nodes only — a floor-wide deployment may need additional AC-powered nodes to maintain coverage, which should be checked against the specific floor plan.
Does Cave Group handle the code filing itself?
No. Cave Group designs and installs the lighting control layer — hardware selection, sensor placement, and commissioning — working alongside the tenant's registered design professional or electrical engineer of record, who owns the controls narrative and code filing.
