The U.S. Division of Power (DOE) revealed a brand new Lighting Market Characterization (LMC) report for baseline 12 months 2020. That is the fourth version of the LMC report; earlier variations have been launched in 2002, 2012, and 2017. By publishing abstract estimates of put in inventory and vitality use of assorted normal illumination lighting merchandise, these studies assist DOE and others plan efficient lighting analysis and improvement packages primarily based on altering wants.

The brand new report particulars what number of lighting merchandise (lamps and luminaires) have been put in within the U.S. as of 2020, the place they have been put in, and the way a lot vitality they consumed. It additionally highlights key adjustments in U.S. lighting market traits between 2015 and 2020.

One of many main adjustments was the rise in LED lighting penetration. In 2010 and 2015, LED installations represented 1% and eight% of general lighting stock, respectively. Against this, LED put in items represented roughly 48% of the put in base in residential and business sectors in 2020.

Extra key findings:

• In 2020, residences accounted for 80% of all lighting installations nationwide, at 6.5 billion put in items in contrast with 1.6 billion lighting installations in business buildings. Whereas this report doesn’t analyze the economic and out of doors sectors, they’re traditionally smaller, accounting for a mixed 5% of put in items within the 2015 LMC.
• In each the residential and business sectors, the typical wattage per put in unit has decreased considerably to roughly 22 watts (W) and 27 W respectively, with a lot of the discount attributable to the persevering with decline of incandescent, halogen, CFL, and linear fluorescent lamps in favor of high-efficiency LED replacements.
• Of the 244 TWh of electrical energy consumed by lighting in U.S. buildings in 2020, roughly 69% was attributable to the business sector—though the variety of put in items was comparatively decrease—because of the increased common wattage and working hours.
• The report highlights persistent inequities in lighting upgrades primarily based on constructing sort. As an illustration, academic establishments lag all different business constructing varieties in adopting probably the most vitality environment friendly lighting, and cellular houses and multifamily houses likewise lag different residential constructing varieties.

The report estimates are primarily based on each public and confidential sources of data together with constructing lighting audits, trade surveys, nationwide lighting product cargo information, and interviews with lighting professionals and subject material consultants.

In line with Christina Halfpenny, government director of the DesignLights Consortium (DLC), “The DLC appreciates the work from DOE to update to the Lighting Market Characterization report. This report is a valuable resource for the DLC and for energy-efficiency programs to plan for market potential and to inform realistic goals to save energy through lighting. These reports provide a baseline for installed lighting that all stakeholders can access and shows progress of lighting technology advancement over time.”
