On behalf of the U.S. Department of Energy’s (DOE) Office of State and Community Energy Programs (SCEP), the Building Technologies Office (BTO) recently announced DOE’s intent to make $1 billion in funding available to states and local governments for improved building codes that reduce carbon emissions and improve energy efficiency through the IRA Funded Technical Assistance for the Adoption of Building Energy Codes.
ASHRAE/IES 90.1-2022 Decoded
The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) and the Illuminating Engineering Society (IES) recently published ANSI/ASHRAE/IES Standard 90.1-2022, Energy Efficiency Standard for Buildings Except Low-Rise Residential Buildings. For lighting, the new version adjusts power allowances, adjusts the definition of alterations, adds horticultural lighting, and updates several control requirements.
Acuity nLight® Offers Title 24 Applications Guide
nLight, a brand of Acuity Brands, recently published an applications guide for California’s Title 24, Part 6 (2022) energy code.
Lighting Controls Association Announces New Course on California Energy Code
The Lighting Controls Association now offers EE203: Lighting Controls and Energy Codes: California Title 24, Part 6 as a new course in its popular Education Express program.
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.
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.
Lighting Controls Association Announces New Course on California Title 24
The Lighting Controls Association (LCA) now offers EE203: Lighting Controls and Energy Codes, Part 4: California Title 24, Part 6 (2019) as a new learning module in its popular Education Express program.
Acuity Brands Offers Resource for IECC 2021 Compliance
The nLight® IECC 2021 applications guide is designed to support compliance with commercial building energy codes based on the 2021 version of the International Energy Conservation Code, or IECC.
Charles Knuffke on Incorporating Non-Energy Benefits into Codes
In his Controls Column contributed to LD+A Magazine in late 2020, Wattstopper’s Charles Knuffke, chair of the Lighting Controls Association, makes the case that energy codes should recognize the non-energy benefits of lighting controls.
Outcome-Based: The Future of Energy Codes?
Outcome-based commercial-building energy codes are an idea gaining new interest among policymakers in the United States. This type of energy code prescribes building energy budgets instead of a complex list of requirements. The first efforts started 10 years ago, and we are still years away from a model sure to gain significant adoption. Due to the concept’s potential benefits, however, it is possible, if not likely, that outcome-based codes will be a tool in future energy regulation.
