Changes to 90.1?

By Staff May 1, 2006

ASHRAE has proposed that the 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.

Specific proposals:

  • Address reasonable alternatives to showing compliance with line-voltage lighting track and plug-in busway lighting requirements;

  • 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 September for possible inclusion in the 2007 IECC Supplement.
