ASHRAE submitted nine proposed changes for the IECC based on ANSI/ASHRAE/IESNA Standard 90.1-2001, Energy Standard for Buildings Except Low-Rise Residential Buildings.
One of the changes would strengthen some of the language and add prescriptive requirements in the section on exterior lighting. The existing section only applies a generic and relatively low efficiency requirement for all lamps, regardless of type or size, with no limit on the quantity of exterior lighting.
The proposal replaces this requirement with a set of prescribed allowances that restrict uncontrolled use of exterior lights while retaining design flexibility with a moderate 5 percent unrestricted additional allowance.
The text of the proposed change is taken from addendum q to Standard 90.1-2001.
ASHRAE’s other proposed changes deal with shutoff dampers, shutoff damper controls, variable air volume control, cooling with outdoor air, installation of insulation above suspended ceilings, and automatic lighting shutoff.
The IECC is a model code that may be adopted by code jurisdictions in the United States or internationally. The proposed changes are scheduled to be evaluated in spring 2005 for possible inclusion in the 2006 IECC.
