Warehouses are large-footprint buildings where lighting and, in some cases, daylighting dominate the energy scope, while HVAC may be limited to offices or conditioned areas. New warehouse construction and warehouse tenant improvements in California require Title 24 (Part 6) documentation for permit.
High-bay lighting and daylighting
Warehouse lighting uses high-bay fixtures, and the Energy Code requires appropriate controls — occupancy sensing and, in large open areas, daylighting controls tied to skylights. Interior lighting is documented on NRCC-LTI, and site and exterior lighting on NRCC-LTO. Because warehouses have large floor areas, lighting power and controls are usually the central part of the report.
Conditioned vs unconditioned space and envelope
Not all warehouse area is conditioned. The report must distinguish conditioned space (typically offices, sometimes climate-sensitive storage) from unconditioned storage, since HVAC (NRCC-MCH) and envelope (NRCC-ENV) requirements apply to conditioned areas. Refrigerated or cold-storage areas add process-load scope (NRCC-PRC). We prepare the certificates that match how the building is actually conditioned.
Skylights, roofs, and site lighting
Warehouse envelope scope centers on the roof and any skylights, which affect both insulation for conditioned areas and whether daylighting controls are triggered for the lit floor below. Cool-roof and insulation details for conditioned space are documented on the envelope certificate, while yard, canopy, and site lighting fall under outdoor lighting (NRCC-LTO). Providing roof and skylight details alongside the lighting plan lets us confirm whether daylighting controls apply and prepare the envelope and outdoor lighting certificates accurately, so the report matches how the building is actually built and lit.
What we need to quote and prepare your report
Send the full plan set so we scope lighting, daylighting, and any conditioned areas:
- Architectural plans showing conditioned vs unconditioned areas
- Lighting plan, high-bay fixture schedule, and controls narrative
- Skylight/daylighting details if applicable
- Mechanical plans and schedules for any conditioned space
- Conditioned floor area and overall building area
- Notes on refrigerated or cold-storage areas
Example project
Illustrative example — not a specific customer: A 40,000-square-foot distribution warehouse has high-bay LED lighting with occupancy and daylighting controls, skylights over the main floor, and a small conditioned office. The project needs NRCC-LTI for lighting and controls and NRCC-MCH/NRCC-ENV for the conditioned office; lighting controls are then verified through acceptance testing.
