Photometric & Illumination
Lighting analysis that balances safety, code compliance, and energy efficiency.
What We Do
A photometric and illumination study is an engineering analysis that measures and models lighting levels across a property to verify compliance with building codes, safety standards, and energy regulations. Advanced Structural Solutions performs photometric analysis for parking garages, building exteriors, common areas, and site lighting across South Florida.
Poor lighting is both a safety risk and a code violation. Dark parking garages, unlit walkways, and inadequate emergency egress lighting expose building owners to liability. A photometric study identifies where lighting falls short and designs solutions that meet code without over-lighting and wasting energy.
Our engineers use industry-standard photometric software to model light distribution, calculate foot-candle levels, and specify fixtures that deliver the right amount of light where it is needed. We also evaluate LED retrofit opportunities that can cut lighting energy costs by 50-70%.
How We Deliver Results
Field Measurement & Assessment
Measure existing light levels with calibrated meters. Document fixture types, mounting heights, spacing, and condition. Identify areas that fall below code-required illumination.
Photometric Modeling
Build a digital model of the space using manufacturer photometric data for existing and proposed fixtures. Calculate illuminance levels at grade and verify code compliance at every point.
Design & Specification
Specify replacement fixtures, layouts, and control systems that meet code requirements and energy targets. Provide fixture schedules, mounting details, and circuiting for contractor bidding.
Frequently Asked Questions
What is a photometric study?
A photometric study uses engineering software to model how light is distributed across a space. It calculates illumination levels in foot-candles at ground level and compares them against code minimums for the specific area type (parking garage, walkway, emergency egress, etc.).
Does my parking garage meet Florida lighting codes?
Many older garages do not. Florida Building Code and IES (Illuminating Engineering Society) standards specify minimum illumination levels for parking structures. If your garage has dim areas, non-functioning fixtures, or has never been evaluated, a photometric study will identify deficiencies.
How much can LED retrofits save on energy costs?
LED retrofits typically reduce lighting energy consumption by 50-70% compared to fluorescent or HID fixtures. For a 200-space parking garage, that can mean $5,000-$15,000 per year in energy savings, often paying for the retrofit within 2-3 years.
Is a photometric study required for building recertification?
Not directly, but structural and electrical certification may identify lighting deficiencies that require remediation. A photometric study provides the engineering documentation needed to demonstrate code compliance after lighting upgrades.
