Begin with the spaces and the work
A lighting retrofit might replace fixtures, change the control system, reconfigure tenant space, or improve common areas. Those projects can have different design and documentation needs. Establish which spaces are involved, which equipment remains, and whether the work is part of a larger alteration.
Lighting design should coordinate the intended use of each space, fixture selections, switching, and controls. A plan that addresses only fixture quantity may leave questions about how the installed system will operate.
Energy code and Local Law 88 are different questions
The applicable energy code addresses the work and filing context. Local Law 88 addresses covered-building lighting and submetering obligations. The project team should assess each question separately rather than assuming that a lighting replacement resolves every building compliance issue.
DOB explains Local Law 88 coverage, covered tenant spaces, and exceptions. Its guidance states that dwelling units in occupancy groups R-2 and R-3 do not require the LL88 lighting upgrades or submeter installation described there. That does not establish the requirements for the building's other spaces or for a separate renovation. Read DOB's LL88 guidance.
Gather the current lighting information
- Lighting plans or a reliable inventory of the affected spaces.
- Fixture types, quantities, and electrical information.
- Existing switching, occupancy, and daylight controls.
- Tenant layouts and available submetering records.
- Prior energy documentation and compliance records.
- The scope and filing information for the proposed alteration.
Coordinate controls and documentation early
Controls affect wiring, equipment selection, and the way occupants use the space. Coordination between the lighting layout and control description helps installers understand the intended operation. Existing wiring and ceiling conditions may also affect the practical retrofit design.
The 2025 NYC Energy Conservation Code applies to completed applications filed on or after March 30, 2026 under DOB's applicability guidance. Earlier and incomplete applications require attention to the published transition instructions. Current NYC energy-code guidance.
Define the engagement before commissioning work
Confirm whether the assignment is a condition assessment, lighting design, energy-code documentation, LL88 support, or a combination. Any filing, inspection, testing, or construction support should be included explicitly. This helps the owner coordinate the electrical consultant with the compliance team and contractor.
Our lighting and energy-code service page describes potential deliverables. Start with the project intake checklist if the electrical scope is still being defined.
