Energy Savings Performance Contracts (ESPCs) allow federal agencies to partner with Energy Service Companies (ESCOs) in procuring, developing, and implementing facility-wide energy-conservation measures (ECMs) as an effort to reduce our federal government’s reliance on inefficient energy and waste. A large part of these contracts is the Lighting Retrofit of the facility’s electrical system, and for decades L&S Enterprises has provided development services, installation labor, and project management for a large portion of the ESPC projects throughout the southeastern United States.
For a Lighting Retrofit to be successful, it is crucial that accurate and thorough data be collected from the existing lighting system via a Lighting System Audit. L&S has developed proprietary data collection software that assists our auditing team in gathering and organizing all of a building’s lighting system information. Some of the data collected includes: room dimensions and ceiling heights, fixture quantities and control types, mounting hardware and foot-candle levels. The data is then sent into development where solutions for each fixture are assigned and a Lighting Savings Analysis (LSA) is generated. Once construction begins, L&S manages the crew in the field as they work room by room, converting and retrofitting every light fixture for which an energy-efficient solution was identified.
Before and After Measurement & Verification (M&V) is performed, as well, as our technicians measure a variety of fixture types for pre and post energy consumption. Typically, the Lighting Retrofit produces a significant savings, and can be offered at times with a Return On Investment (ROI) between 30-40%. With technologies constantly evolving, the Lighting Retrofit continues to be one of the most affordable and high-yielding investments a property owner can make.
