Just as the US Department of Energy (DOE) recognized ANSI/ASHRAE/IESNA Standard 90.1-2010 as the national energy standard, WattStopper launched a new CodeSmart publication designed to guide lighting and building professionals through the intricacies of the many lighting control requirements that debuted in this newest version of the code. The informative booklet available for free download […]
Department of Energy Names ASHRAE 90.1-2010 as New National Energy Standard
In July 2011, the Department of Energy recognized the ASHRAE/IES 90.1-2007 standard as the new national energy standard, superseding the 2004 version. In a bold move, on October 19, 2011, DOE recognized the 2010 version of 90.1 as the new national energy standard. By October 18, 2013, all states in the United States must put […]
Consulting-Specifying Engineer Publishes Article About Lighting And Control Changes in ASHRAE 90.1-2010
Consulting-Specifying Engineer has published an article by Brian Baumgartle, PE, LC, LEED AP of CMTA Inc. about lighting and control changes in the ASHRAE/IES 90.1-2010 energy standard, recently recognized by the Department of Energy as the national energy standard effective October 2013. Check it out here.
Daylight Zones: Toplighted Spaces
Last month at LightingControlsAssociation.org, we published an article about how to establish daylight zones in sidelighted (windowed) building spaces. We looked at an industry rule of thumb and then how the latest generation of energy codes and standards address it. In review, when designing an energy-saving daylight harvesting control system, a critical decision is to […]
Daylight Zones: Sidelighted Spaces
When designing an energy-saving daylight harvesting control system, a critical decision is to establish lighting control zones, identifying lighting loads to be separately controlled. Before this decision can be made, however, we must first determine the daylight zones. A daylight zone, also called the daylight area (expressed in square feet), is defined by the ASHRAE/IES […]
Control Design Toolbox: The Lighting Controls Narrative
As demand for lighting controls continues to grow, advanced solutions are becoming increasingly specified while also becoming increasingly sophisticated. This increasing sophistication translates to greater owner benefit but can also pose greater risk of design and installation mistakes. In a perfect world, designers create clear and detailed lighting control requirements that are easily installed by […]
Energy Standards Take On Daylight Harvesting
Because of the strong energy savings potential offered by daylight harvesting, coupled with advancing technology, codes and standards are now beginning to address daylight harvesting—specifically, International Energy Conservation Code (IECC) 2009, ASHRAE/IES 90.1-2010, ASHRAE 189.1 and Title 24-2008.
ASHRAE Releases 90.1-2010–Part 2: Lighting Controls
Last month, the Lighting Controls Association published a guide to the new ASHRAE/IES 90.1-2010 standard, focusing on its prescriptive lighting power requirements as well as significant changes to its scope and administrative requirements. In Part 2 of this series on the new standard, we will focus on its extensive new mandatory and optional lighting control requirements. Regarding controls, the changes are nothing short of historic.
ASHRAE Releases 90.1-2010–Part 1: Design, Scope, Administrative Requirements
ASHRAE/IES 90.1, Energy Standard for Buildings Except Low-Rise Residential Buildings is published every three years to provide states and other jurisdictions with a model commercial building energy code. The 2010 version, published November 2010, represents the most dramatic revision of the standard since 1999. In this two-part series of special reports by the Lighting Controls Association, we will examine the new energy standard in detail. Part one, presented here, focuses on changes to the prescriptive lighting power requirements as well as changes to scope and administrative requirements. Part two, to be published next month, will focus on the standard’s extensive list of new mandatory and optional lighting control requirements.
New York City Requires Lighting Upgrades in Largest Buildings
To help achieve the PlaNYC goal of a 30% reduction in greenhouse gases by the year 2030, on December 9, 2009, the New York City Council enacted ambitious legislation targeting energy consumption in buildings. Recognizing that 85% of the buildings that exist today will still be in use in 2030, the Council is focusing on existing buildings. New York’s 22,000 largest buildings, concentrated largely in Manhattan, account for roughly 45% of total floorspace and energy consumption, and were specifically targeted by the legislation to make the biggest impact for the smallest amount of government intervention.
