Lighting Engineering Services
"Smart Design. Real-World Execution. Proven Results."
Pearl Street employs one of the largest and most specialized lighting auditing staffs in the nation. While we perform rigorous audits for our own turnkey projects, we also provide these standalone services directly to facility owners, end-users, and contractors. Beyond comprehensive lighting audits, we offer a full spectrum of engineering, design, and technical services to support complex lighting retrofits and new construction projects.
At Pearl Street Systems, elite engineering is the foundation of every successful project. Our in-house team delivers practical, buildable solutions that perfectly balance performance, cost, and constructability—ensuring your project succeeds not just on paper, but out in the field.
Our engineering recommendations are grounded in real-world field implementation experience, helping ensure systems function properly not only in design documents, but during actual construction and long-term operation.
Engineering That Works The best design is the one that gets built right the first time. Pearl Street’s engineering team develops highly efficient, performance-driven solutions that keep your projects moving forward quickly and with absolute confidence.
Core Engineering Capabilities
Lighting Upgrade Assessments Our project and program assessments provide a high-level, low-cost screening of the financial and environmental benefits of a proposed lighting upgrade. This crucial first step quickly determines if a more comprehensive, line-by-line Investment Grade Lighting Audit (IGLA) is strategically and financially warranted for your facility.
Investment Grade Lighting Audits (“IGLAs”) Pearl Street’s IGLAs are exhaustive, highly detailed, and completely manufacturer independent. Our real-world experience implementing complex lighting upgrades translates into a high-quality, actionable data package. This allows facility owners to make confident investment decisions and provides contractors with the exact specifications needed to bid and build accurately.
Our IGLAs are also structured to support full energy code compliance in any market. Unlike firms that deliver an upgrade and leave you to find a PE to file, Pearl Street supports clients through every step of the process — including final attestation filing with the NYC Department of Buildings, ensuring your facility is fully documented, compliant, and closed out.
- Unmatched Scale and Expertise: We deploy one of the largest and most highly skilled auditing staffs in the country, analyzing tens of millions of square feet of facility spaces annually.
- Advanced Technology: We utilize state-of-the-art, tablet-based auditing software, ensuring rapid, highly accurate data collection, precise upgrade modeling, and flawless final deliverables.
- Total Risk Mitigation: If experience has taught us anything, it is that the ultimate success—or failure—of a lighting upgrade relies entirely on the quality of the initial audit. A Pearl Street IGLA protects you from risk of extensive contractor change orders, compromised energy savings, or subpar system reliability.
Lighting Systems Field Retro-Commissioning While HVAC and mechanical systems retro-commissioning has been an industry standard for over 30 years, lighting systems are frequently overlooked. As these systems become increasingly software-driven and interconnected with broader building operations, proper system configuration, commissioning, and ongoing optimization are more important than ever.
In our experience, a significant majority of existing building lighting control systems fail to achieve their original design intent.
Many existing lighting control systems continue operating on default programming settings years after installation, resulting in unnecessary energy consumption, occupant complaints, and underperforming systems.
We routinely identify and resolve critical inefficiencies, including:
- Improperly programmed time clocks and scheduling relays
- Miscalibrated or unresponsive occupancy sensors
- Ineffective daylight harvesting integrations
- Chronically over-lit or under-lit facility zones
Our retro-commissioning process identifies and implements low-to-no-cost field adjustments that drastically improve your system's energy efficiency, optimize lighting performance, and finally deliver the savings your hardware was designed to achieve.
