A Closer Look at Our New National Energy Standard: Comparison of the 1999 and 2004 Versions of ASHRAE 90.1

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 [...]

Stimulus Package Encourages States to Use Standard 90.1-2007

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.

What’s New for Lighting in IECC 2009?

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.

What if 80% of the lamps in your house had to be fluorescent?

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.

IDA and IES Publish Outdoor Model Lighting Ordinance for Public Review

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 [...]

Lighting Designers Likely to Find 2009 IECC Disappointing

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. [...]

Lighting and ASHRAE 90.1-2007

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.
