ASHRAE proposes lighting changes
Proposals from ASHRAE would “light the way” for the International Energy Conservation Code to be more consistent with the Society’s energy efficiency standard.
ASHRAE has proposed that portions of ANSI/ASHRAE/IESNA Standard 90.1-2004, Energy Standard for Buildings Except Low-Rise Residential Buildings, dealing with lighting be adopted in the International Energy Conservation Code published by the International Code Council.
“Electric lighting consumes 20 to 25 percent of electricity used in buildings,” said Eric Richman, chair of the 90.1 Lighting Subcommittee. “Lighting also produces additional heat in buildings, with the heat from lighting accounting for 15%%MDASSML%%20% of a building’s cooling load. The lighting provisions in Standard 90.1 are a significant efficiency improvement over past versions, so ASHRAE encourages the ICC to adopt these lighting improvements for the IECC.”
Specifically, the proposals address reasonable alternatives to showing compliance with line-voltage lighting track and plug-in busway lighting requirements; and provide additional control options for exterior lighting. Additional proposals from 90.1 unrelated to lighting include:
•Add a table of U-factors to match the prescriptive R-value table in the code
•Strengthen the requirements for hot gas bypass
•Address HVAC system completion and commissioning requirements.
The proposed changes are scheduled to be evaluated in Sept. 2006 for possible inclusion in the 2007 IECC Supplement.

Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
