Next month, the 2016 version of ANSI/ASHRAE/IES 90.1, Energy Standard for Buildings except Low-Rise Residential Buildings, takes effect as the national energy reference standard, based on a 2018 Department of Energy (DOE) ruling. By February 2020, all states must adopt a commercial building energy code at least as stringent as the standard, or justify why they cannot comply.
ASHRAE/IES 90.1-2019 Decoded
The American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) and the Illuminating Engineering Society (IES) recently published ANSI/ASHRAE/IES Standard 90.1-2019, Energy Efficiency Standard for Buildings Except Low-Rise Residential Buildings. This edition includes more than 100 changes from the 2016 version, covering administrative and enforcement, commissioning, mechanical, and lighting. For lighting, the new version adjusts interior power allowances, updates several control requirements, and introduces a simplified compliance method for office, school, and retail buildings.
Quick Guide to The Latest Commercial Building Energy Code Standards
This article provides general introductory knowledge about the lighting control requirements imposed by the 2016 version of ASHRAE/IES 90.1 and the 2018 version of the IECC.
Steve Mesh on the 2019 Version of Title 24
One of the most striking changes to the 2019 code version is the addition of Section 130.1(f)1-130.1(f)7 – “Control Interactions.”
Lighting Controls in the Time of Low Lighting Power
“I recently wrote about how lighting energy allowances under current codes are now approaching a practical minimum, thanks to significant improvements in source efficacy, optical efficiency, and controls that automatically extinguish lighting when it is not needed.”
Decoding IECC 2018
On July 26, 2018 the International Code Council published the 2018 version of the International Energy Conservation Code (IECC), which has been updated every three years since 2000. This 2018 version reduces lighting power allowances, broadens mandatory controls requirements, and issues clarifications.
Eaton’s Michael Lunn on Plug Load Controls
Craig DiLouie, LC, CLCP recently interviewed Michael Lunn, Director, Product Marketing, Eaton Corporation, on the topic of plug load control.
Steve Mesh on California’s Title 24 Energy Code and Lighting Controls
California has been a historical leader in terms of state energy codes. California’s Title 24 has led the way by restricting allowable LPDs (Lighting Power Density) as well as mandating specific types of lighting controls. This article by Steve Mesh introduces the Title 24 energy code and its lighting control requirements.
California Energy Alliance Code Change Language Adopted by California Energy Commission in Proposed Title 24-2019 Updates
The California Energy Alliance (CEA) has announced that its code change proposal dedicated to improving the lighting control requirements for lighting alterations was accepted by the California Energy Commission (CEC) in its recently published Draft Express Terms. CEA’s code change proposal includes simplified language with reduced application and/or project-specific requirements; an easy-to-understand energy savings option for small buildings and tenant spaces; and a universal compliance threshold and set of exemptions.
Automatic Control for Plug Loads
Controlling plug loads is a natural fit for the lighting controls industry, as the same devices and strategies are used for automatic shutoff of plug loads such as task lighting as for general lighting. This feature article by LCA Education Director Craig DiLouie, LC, CLCP looks at energy code requirements, compliance options, and control types.
