Preparation guidance for energy compliance documentation in Irvine, California. Remote statewide service; local requirements come from your building department.
Hypothetical example / Irvine
Office tenant improvement with daylighting
Imagine an office with skylights where lighting controls may need daylighting provisions. Ask the electrical designer about daylight controls. Daylit zones under skylights or near windows may require separate controls. Ask the electrical designer to identify these zones on the plans and coordinate with the preparer. Provide skylight specifications if they are being replaced. If the HVAC is changing too, coordinate mechanical and lighting documentation so both reflect the same floor plan and occupancy.
Illustrative scenario only; not a statement about local projects, climate or permit rules.
Scenario checklist
- Identify daylit zones
- Plan controls
- Provide fixture schedule
- Confirm forms
