In 2023, commercial lighting rebates remain a strong driver for adoption of energy-efficient lighting and controls in existing buildings. Notable trends include continuing stability in LED and control rebates, imminent jeopardy for some LED replacement lamp rebates, and growth for networked lighting control and horticultural rebates. A coinciding trend with implications for lighting upgrades is introduction of substantial rebates for electric vehicle (EV) charging stations.


2023 Nonresidential Construction Forecast: “Moderate”
A major contributor to the economy is construction, which overall exhibited very strong growth in 2022. Despite a strong finish to the year, however, nonresidential construction spending is expected to moderate in 2023 and slow significantly in 2024, according to the American Institute of Architects (AIA) Construction Consensus Forecast Panel made up of leading economic forecasters. The Panel forecasted that nonresidential construction spending will moderate to grow a healthy 5.8% in 2023 but then slow to less than 1% in 2024.

Lighting Controls Association: Year in Review
The Lighting Controls Association was founded as a council of NEMA back in 2001 to promote adoption of lighting controls through education. Today, the association continues to make a demonstrable difference in supporting public expertise in selecting, designing, installing, and operating lighting control systems. This article outlines the LCA’s accomplishments in 2022 and offers a preview of what’s to come in 2023.

D4i: Standardizing Luminaire-Level Control
The DALI Alliance recently extended DALI-2, which standardizes interoperability and control of LED drivers and sensors, with a version that more finely addresses the needs of the Internet of Things, which calls for individual device addressability, connectivity, and two-way data exchange.

Lighting Control: What’s in the New Title 24?
On January 1, 2023, the 2022 version of California’s energy code—Title 24, Part 6 of the Building Standards Code—takes effect, superseding the previous 2019 version. In terms of lighting controls, the numerous changes include various clarifications and tuning along with two major provisions requiring occupant-sensing in offices larger than 250 sq.ft. and demand-responsive lighting controls. Designers and specifiers need to understand these changes before they begin working on code-covered new construction and alteration projects that will go out for permit in California in 2023.

Commercial Buildings Tax Deduction Expands
The new incarnation of the Commercial Buildings Tax Deduction offers a strong incentive to stretching energy efficiency in new buildings and modernizing existing buildings. In new buildings, it incentivizes more detailed design and the most advanced control options. In existing buildings, it incentivizes a wide range of lighting and advanced control options that, when coupled with available utility rebates, can substantially reduce initial cost that remains the largest inhibitor to investment in reducing operating costs via energy efficiency.

DOE Recognizes 90.1-2019 as National Energy Standard
Next year, the 2019 version of ANSI/ASHRAE/IES 90.1, Energy Standard for Buildings except Low-Rise Residential Buildings, takes effect as the national energy reference standard. This is based on a July 2021 Department of Energy (DOE) ruling that determined the standard saved more energy than the preceding 2016 version. By July 28, 2023, all states must adopt a commercial building energy code at least as stringent as the standard, or justify why they cannot comply.

Best Practices for Lighting Control Narratives
As lighting controls become more sophisticated in application and capabilities, properly documenting the system’s intent and settings becomes critical. One of the most important documents is the control narrative, including a detailed sequence of operations. Though required by commercial building energy codes as documentation for many new construction and major renovation projects, aside from the Lighting Controls Association, manufacturers, and a few other sources, there are few resources providing guidance about how to write them. Enter the Illuminating Engineering Society (IES), which took on the challenge by publishing ANSI/IES LP-16-22, Documenting Control Intent Narratives and Sequences of Operations in June 2022.

Introduction to Luminaire-Level Lighting Controls
Luminaire-level lighting controls (LLLC), also called embedded controls, are lighting control systems in which sensors and controllers are installed within luminaires to enable autonomous, individual luminaire control. By making each luminaire a control point, control is highly flexible, responsive, and therefore generally more energy-saving. Serving as a preview for an upcoming Education Express course, this article describes LLLC technology, system types, advantages and disadvantages, studies characterizing energy savings and cost, and what’s familiar and distinctive in regards to design and installation.

2022 Rebate Outlook
The commercial market lighting rebate outlook for 2022 is even stronger than 2021, with relatively stable, substantial rebates promoting adoption of energy-efficient lighting and controls.
