The U.S. Division of Power (DOE) printed a brand new Lighting Market Characterization (LMC) report for baseline yr 2020. That is the fourth version of the LMC report; earlier variations had been launched in 2002, 2012, and 2017. By publishing abstract estimates of put in inventory and vitality use of varied basic illumination lighting merchandise, these reviews 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) had been put in within the U.S. as of 2020, the place they had 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 total lighting stock, respectively. Against this, LED put in models 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 models in contrast with 1.6 billion lighting installations in business buildings. Whereas this report doesn’t analyze the commercial and out of doors sectors, they’re traditionally smaller, accounting for a mixed 5% of put in models 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 models was comparatively decrease—because of the greater common wattage and working hours.
• The report highlights persistent inequities in lighting upgrades primarily based on constructing kind. As an example, instructional establishments lag all different business constructing sorts in adopting essentially the most vitality environment friendly lighting, and cell properties and multifamily properties likewise lag different residential constructing sorts.

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 material specialists.

In line with Christina Halfpenny, govt director of the DesignLights Consortium (DLC), “The DLC appreciates the work from DOE to replace to the Lighting Market Characterization report. This report is a precious useful resource for the DLC and for energy-efficiency packages to plan for market potential and to tell reasonable objectives to avoid wasting vitality by way of lighting. These reviews present a baseline for put in lighting that every one stakeholders can entry and reveals progress of lighting expertise development over time.”
