Why we like the new DOE transformer rule

Why we like the new DOE transformer rule

Recently the U.S. Department of Energy posted the Final Rule for the energy efficiency rulemaking for Distribution Transformers.  http://www1.eere.energy.gov/buildings/appliance_standards/product.aspx/productid/66  While some entities have criticized the Government’s final decision, the DOE Final Rule was largely on target.  DOE worked through huge amounts of data from all sides and came to a fairly good result. NEMA stuck to a few principles—backed up by data—throughout Read more [...]
California thermostats and new home owners

California thermostats and new home owners

In the California Building Code, dozens of proposals are being finalized for Title 24.  One of considerable interest to the NEMA Residential and Commercial Controls Section involves the requirement of a device called an Upgradeable Setback Thermostat, or UST, in new construction homes.  A UST is essentially a wireless programmable thermostat with the radio removed and a port available where a radio module may be inserted later.  The goal of this proposal, developed by CEC staff, advocates Read more [...]
How can I tell which Exit Sign is best?

How can I tell which Exit Sign is best?

When Energy Star closed the exit sign category, specifiers and inspectors no longer had a mark of distinction with which to identify top-tier products.  There were even instances of people seeking out new old stock Energy Star labeled signs and preferring them over newer (better) signs, just because of the brand recognition of Energy Star. In response to concerns over the loss of the Energy Star program and associated marks, the NEMA Emergency Lighting Section established the NEMA Premium Exit Read more [...]
NEMA Lighting Division efforts bear fruit in California

NEMA Lighting Division efforts bear fruit in California

This week the State of California Public Utilities Commission (CPUC) approved and published their Strategic Lighting Plan, which was two years in the making. NEMA staff and members participated directly in the development and drafting of the SLP from start to finish to provide the manufacturer perspective in effort to balance out the advocates and regulators, and to serve as a reality check by leveraging NEMA's extensive experience with consumer acceptance and consumer desires.  The Strategic Read more [...]
Filling in the Gaps in Lighting Solutions

Filling in the Gaps in Lighting Solutions

Today many concerned building owners, lighting designers and some regulators are increasing their efforts and attention on free, natural light.  Unfortunately, while it is certainly very energy efficient, it is not reliable.  Like all renewable resources it is subject to periods of unavailability, not just at night but also during the day.  Natural variation in the intensity of sunlight can be a challenge.    Retail and Task-oriented lighting plans require Read more [...]
Lighting industry position on light at night and biological factors forthcoming

Lighting industry position on light at night and biological factors forthcoming

The NEMA Lighting Systems Division is concerned over numerous recent efforts to raise awareness of light at night and potentially related effects on biological processes.  While many of these are well-intended, they often fall short of being credible, and could do more harm than good.  There are many instances where lighting at night is favored and desired for safety and aesthetics, and ultimately NEMA lighting manufacturers wouldn't sell products if they weren't in demand.  Read more [...]
NEMA Addresses SSL Dimming Challenges

NEMA Addresses SSL Dimming Challenges

The NEMA Lighting Controls and Solid State Lighting Sections have co-produced a white paper on the subject of dimming screw-base integrated ballast LED lamps. It is designated LSD-49 and is titled "Solid State Lighting for Incandescent Replacement—Best Practices for Dimming". NEMA and the SSL industry hope that by issuing guidance as early as possible on this subject, SSL technology can avoid the pitfalls associated with less than compatible self-ballasted CFL and Dimmer combinations.

Green in color only, sometimes. Concerns over advertising claims for Photoluminescent exit signage

Green in color only, sometimes. Concerns over advertising claims for Photoluminescent exit signage

Caveat Emptor, and Carry a Flashlight? Photoluminescent (PL) exit signs can be an excellent addition to the life safety outfitting of many facilities.  Their ease of application and use lend them to be favored by many building operators and sometimes even required by life safety codes.  However, PL signage must be applied and maintained properly and has its limitations.  Too often advertising claims gloss over or ignore some very critical points that anyone considering Read more [...]
New UL Holographic Labeling Requirements and NEMA Product Sections

New UL Holographic Labeling Requirements and NEMA Product Sections

Recently, Underwriters Laboratories sent a letter to NEMA Luminaire manufacturers announcing a January 1, 2009 requirement to implement holographic labeling in support of an expanding UL program to fight counterfeit products.  Historically, UL has only applied these requirements to products made overseas, China notably.   NEMA manufacturers are naturally concerned about counterfeiting, but are pushing back against the new UL label for more time and if possible more flexibility in the Read more [...]
