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.
In this video, the Lighting Practice’s Emad Hasan, IALD, LEED AP BD+C discusses the impact of energy codes on lighting and how lighting controls can save energy by reducing the amount of time light is used. Emad also explores the impact on occupants and the different ways lighting designers balance code requirements, occupant comfort, and impactful lighting solutions.
Synapse Wireless has published guidance to achieving best practices and energy code compliance for parking garage lighting control. The guidance describes various relevant regulations and what strategies and equipment are required. “Parking garages can be a challenging environment for lighting designers. From seasonal outdoor daylight patterns, to underground levels, these spaces are a microcosm for […]
In January 2021, the International Code Council published the 2021 version of the International Energy Conservation Code (IECC), which has been updated every three years since 2000. This new version reduces lighting power allowances, expands mandatory controls requirements, and issues clarifications.
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.
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.
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.
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.”
“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.”
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.
