Proper lighting is vital for safety, functionality, and aesthetics in outdoor spaces. Our photometric calculations optimize lighting designs for parking lots, pathways, and building exteriors, ensuring compliance with municipal regulations and safety standards. By focusing on energy efficiency and uniform illumination, our designs enhance the overall appearance and usability of your property while streamlining the approval process.

Photometric Calculations for Site Plan Approval (SPA) — frequently asked
- What is a photometric plan and why does the city require one?
- It maps light levels across a site to confirm the lighting is adequate for safety without spilling onto neighbouring property. Municipalities use it to assess a Site Plan Approval submission.
- What information do you need to produce one?
- A site plan, the proposed fixture types or a lighting allowance, and the municipality's lighting criteria. We can recommend fixtures if they have not been selected.
- Do you handle exterior lighting for parking lots and walkways?
- Yes — parking areas, drive aisles, pedestrian walkways, and building facades, designed for uniform illumination and energy efficiency.
