Energy, controls, maintenance, end-of-life recycling, and luminaire replacement planning for lower operating impact, framed against Science Based Targets initiative trajectories, ASHRAE 90.1 Appendix G energy modeling, and Greenhouse Gas Protocol Scope 1, 2, and 3 reporting boundaries used by the corporate sustainability team.
Public reporting against Science Based Targets initiative trajectories shows the company tracking a 50 percent absolute Scope 1 and Scope 2 emissions reduction by 2030 from a 2019 baseline, supported by recycled aluminum in luminaire housings, single-stream packaging redesigns that took 12 million pounds of corrugate out of the supply chain, and a portfolio of DLC Premium SKUs that average 145 lm/W versus the legacy fluorescent baseline near 60 lm/W.
Savings Demo / interactive calculator layout
An interactive baseline calculator accepts square footage, occupancy schedule, blended utility rate, and existing wattage per fixture, then returns proposed Lithonia and Holophane LED replacements with kWh per year reduction, demand-charge offset in kW, simple-payback in months, and lifetime CO2e avoided in metric tons assuming the local eGRID subregion emissions intensity.
Compares two-lamp 32W T8 fluorescent baselines against 24W BLT-LP troffer replacements at equivalent 4,000 lumen output, holding 30 maintained footcandles across the floor plan and reporting kWh per square foot per year savings against the existing utility billing record.
Estimates kW reduction at building peak using ASHRAE 90.1 occupancy schedules so utility demand-charge savings appear separately from kWh consumption savings, allowing facilities directors to forecast operating budget changes alongside Scope 2 emissions reduction in their annual sustainability disclosure filings.
Pulls midstream and prescriptive incentives from DLC member utility programs covering DLC Premium qualified SKUs, networked-controls credits per fixture, and submetering bonuses, then layers the available federal 179D commercial buildings deduction value into the simple-payback calculation.
Reports lifetime metric tons of CO2e avoided using the project ZIP code eGRID subregion emissions factor, an L70 fixture life of 100,000 operating hours, and a continuous on duty cycle assumption for hospitality and 24x7 industrial scopes that runs through the entire warranty window.
Case Studies / card grid
Recent reference projects include a 1.4 million square foot Midwest distribution center retrofit that replaced 4,200 metal-halide high-bays with Holophane Predator IBG units on networked nLight aisle control, a Pacific Northwest medical campus that converted 18 buildings to tunable-white nCom downlights with DALI-2 zoning, and a Northeast university roadway lighting refresh that swapped 760 cobra-head HPS poles for D-Series Type II area lights with ANSI C136.41 dimming receptacles.
4,200 metal-halide high-bays replaced with Holophane Predator IBG round LED units across a 1.4 million square foot footprint; raw energy use dropped 64 percent against the prior fluorescent and HID baseline and aisle-level occupancy control added another 12 percent runtime savings.
An 18-building Pacific Northwest healthcare campus moved to nCom downlights and recessed linear with DALI-2 zoning, supporting clinical 5000K exam modes, patient-rest 2700K evening modes, and corridor sleep modes calibrated to nursing-station overrides at the central control panel.
760 HPS cobra-head roadway poles across a Northeast university campus were swapped for D-Series Type II area lights with ANSI C136.41 dimming receptacles, scheduled curfew dimming, and Atrius scheduling overrides for game-day stadium events and late-night academic shuttle routes.
Holophane Prismalume IP66 freezer fixtures certified to -40 C cold startup replaced T8 fluorescent strips inside a multi-temperature grocery distribution center; lighting maintenance truck rolls dropped 73 percent and aisle scanning errors fell measurably under the higher CRI illuminant.
