In this post, I noted that ASHRAE Standard 90.1-2004 has been established by the Department of Energy as the commercial building reference standard for state building energy codes starting in 2010. Meanwhile, the stimulus package appears to be encouraging adoption of the latest version, which is 90.1-2007, as noted in this post. I promised a [...]

The stimulus package, the American Recovery and Reinvestment Act, focuses on economic stimulus through both tax credits and public-sector spending, with a heavy focus on infrastructure and energy. Here’s an interesting development I had missed at first glance through it: The Department of Energy is offering $16.8 billion to the states for a variety of [...]

The Lighting Controls Association has published an article I wrote on the topic of the major lighting changes in the 2009 version of the International Energy Conservation Code (IECC) related to commercial buildings. One of the most controversial changes isn’t directly related to lighting, but it could have a significant impact on lighting design. Previous [...]

The residential section of the 2009 version of the International Energy Conservation Code (IECC), recently published, has a new Section 404, which covers residential lighting. It’s the first time IECC has covered residential lighting efficiency. The entire section reads simply: “404.1 Lighting equipment (prescriptive). A minimum of 50% of the lamps in permanently installed lighting [...]

The latest research shows that at least 10% of all outdoor lighting, even fully shielded lighting, ends up creating light pollution, according to the International Dark-Sky Association (IDA). Many communities across the U.S. have tried to deal with light pollution or some facet of it–sky glow, light trespass and, more rarely, glare–with a patchwork of [...]

The International Code Council’s (ICC) 2009 version of the International Energy Conservation Code (IECC), a model energy code adopted by many states, contains a number of lighting-related provisions that lighting designers are likely to find objectionable. One area of concern is that the 2009 IECC eliminates mixing methodologies from ASHRAE 90.1 as an alternative standard. [...]

ANSI/ASHRAE/IESNA Standard 90.1-2004, Energy Standard for Buildings Except Low-Rise Residential Buildings, has been established by the Department of Energy as the commercial building reference standard for state building energy codes starting in 2010. By December 30, 2010, all states in the United States must certify that their building codes meet or exceed the requirements in [...]

The U.S. Green Building Council recently reaffirmed its commitment to the development of Standard 189.1P, which will be America’s first National Standard developed to be used as a green building code when completed. Created specifically for adoption by states, localities, and other building code jurisdictions that are ready to require a minimum level of green [...]

In March 2008, TED Magazine, the NAED publication for electrical distributors, published my column summarizing the lighting changes of the ASHRAE 90.1-2007 energy standard. ASHRAE 90.1-2007 did not make power allowances more stringent, but did include a number of significant refinements. Click here to read the article. According to the Building Codes Assistance Project, as [...]
