LIGHTING ENERGY STUDY

The lighting energy study that TRC provided included the existing technology, the recommended replacement, as well as additional recommendations for replacements. You could clearly see what was the best way to go. In fact, the proposed cost savings was a reduction in annual energy costs by 58%.” – Lee Morem, ISD #299 Caledonia Public Schools

Jake Energy Study Quote

The move to LED lighting is no longer a question of if—it’s a matter of when. Whether you haven’t yet upgraded, have completed some upgrades, or are ready for the next phase adding lighting controls, every organization is somewhere on the roadmap to an LED conversion.

No matter where you are in that journey, a Lighting Energy Study can help you move forward with confidence, providing a comprehensive assessment of your current lighting system—identifying the areas that have already been upgraded, which have not, and where opportunities exist to reduce energy usage, lower maintenance costs, and improve lighting performance.

 

 

Lighting Energy Study Deliverables

  1. Reduced Energy Usage
    • kW, kWh, and System Wattage Analysis: A detailed report analyzing current demand (kW), consumption (kWh), and the total system wattage of the existing and proposed lighting.

    • Lighting Controls Savings Impact Data: Data providing the estimated energy reduction and savings achievable through the implementation of lighting controls (e.g., occupancy sensors, daylight harvesting).
    • Savings Summary and Cost of Ownership Report: A comprehensive financial summary projecting the annual energy savings, project payback and the overall Return on Investment (ROI).

    • Utility Rebate Analysis: A dedicated deliverable that identifies all available financial incentives from your utility company and calculates the specific eligible rebate amount for all proposed LED solutions and lighting controls, ensuring you maximize incentives and accurately calculate the net project cost.
  1. Lower Maintenance Costs
    • Catalog of Existing Lighting Technology: A full inventory and specification breakdown of all current lighting fixtures (fixture type, quantity, wattage, operating hours) across the facility.

    • Detailed Proposed Scope of Work: A clear, itemized document outlining the proposed installation plan, required materials, and the scope of labor for the lighting upgrade project, broken down by area.

    • Maintenance Savings Analysis: A quantified report demonstrating the projected reduction in labor and material costs due to switching to longer-life, lower-maintenance LED technology.
  1. Improved Lighting Performance
    • LED Solution Options Analysis: An evaluation of viable LED product options (including efficiency, efficacy, and color temperature) tailored to your facility's specific application needs.

    • Solution Specifications: The complete technical specifications for the selected LED fixtures, lamps, and associated equipment.

    • Photometric Layouts: Visual plans and renderings showing the proposed lighting design and demonstrating that the new solution will meet or exceed required light levels (lux/foot-candles) and distribution uniformity; for certain applications.

How can you use this information?

Turnkey Project Upgrade

For a turnkey LED upgrade project addressing your entire facility, the deliverables provide all the necessary information for planning, budgeting, execution, and verification.

  • Financial Justification: The Savings Summary and Cost of Ownership Report, combined with the kW, kWh, and System Wattage Analysis and Maintenance Savings Analysis, establishes the complete financial case. This data shows the upfront investment, the ROI, and the long-term energy and maintenance cost savings, which are essential for securing budget approval.

  • Design: The LED Solution Options Analysis, Solution Specifications, and Photometric Layouts define the exact products and the detailed design required for the upgrade. This ensures the new lighting will deliver the targeted performance (light levels and quality) while maximizing energy efficiency.

  • Execution Plan: The Detailed Proposed Scope of Work acts as the formal blueprint for the installation contractor, outlining every step required to remove the old system and install the new LED fixtures and controls.

  • Procurement: The Catalog of Existing Lighting Technology helps ensure correct component removal and disposal, while the Solution Specifications drive the accurate procurement of all new fixtures and controls.

Strategic Lighting Maintenance

If a full capital project isn't immediately feasible, these same deliverables are the foundation for a comprehensive strategic lighting maintenance plan.

  • Identify Upcoming Maintenance Needs: The Catalog of Existing Lighting Technology is key. It identifies all current fixture types and locations. By cross-referencing the current age of the system and expected life of the technology, you can predict which areas will require the most immediate and frequent maintenance.

  • Prioritize Areas for Maximum Benefit: The kW, kWh, and System Wattage Analysis and the Maintenance Savings Analysis allow you to prioritize areas for phased upgrades or targeted maintenance. You can focus on:
    • Areas with the highest energy consumption (kWh) for the quickest reduction in operating costs.
    • Areas with immediate maintenance needs that fit into your operating budget.

  • Develop a Consistent Specification Plan: The LED Solution Options Analysis and Solution Specifications establish a new, consistent standard for your facility. Instead of replacing failed lamps with the same outdated technology, the plan dictates that all replacement fixtures going forward must meet the new consistent LED technology, wattage, lumen output, and color temperature specification. This prevents the "lighting patchwork" look, ensures safety and performance standards are met, and makes future maintenance simpler by reducing the variety of parts needed.
