Changes to 90.1?
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.
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.
