TO: The Honorable Mayor and City Council Members
FROM: Michael C. Van Milligen, City Manager
SUBJECT: International Energy Conservation Code
DATE: January 15, 2008
Building Services Manager Rich Russell is recommending adoption of the 2006
International Energy Conservation Code, with four amendments to more accurately
reflect the gaming industry's use of lighting, published by the International Code
Council. The adoption of the 2006 International Energy Conservation Code will enable
enforcement and amendment of this code at the local level. The Building Services
Department currently forwards energy code questions to the State of Iowa Building
Code Bureau. The adoption of the Code would also contribute to achieving the City
Council top priority of a "Green Community."
I concur with the recommendation and respectfully request Mayor and City Council
approval.

SUBJECT: International Energy Conservation Code
DATE: December 18, 2007
INTRODUCTION: The purpose of this memo is to recommend the amending of the City
Ordinance by adoption of the 2006 International Energy Conservation Code (IECC)
published by the International Code Council, Inc.
BACKGROUND: The adoption of the 2006 International Energy Conservation Code will
enable enforcement and amendment of this code at the local level. The Building
Services Department currently forwards energy code questions to the State o_ f Iowa
Building Code Bureau.
DISCUSSION: The adoption of the 2006 International Energy Conservation Code will
allow general contractors, architects, system designers and Building Services staff
members to use an up= to=-date energy code. The adoption of the 2006 International
Energy Conservation Code will help us maintain or improve our current ISO rating of 4.-
The adoption of the 2006 International Energy Conservation Code would also contribute
to achieving the Council top priority of a "Green Community".
There are four amendments proposed to more accurately reflect the needs of the
gaming industry's use of lighting. They are as follows:
1. Three definitions are added to Section 202 of the 2006 IECC. The "Back of
House" and "Front of House" of Gambling Facilities are defined to distinguish the parts
of a gambling structure that are accessible to the public (Front of House) and those
areas which are used by authorized personnel only (Back of House). A definition of
"display kitchens" is also added to Section 202 to provide a description for portions of
kitchens visible to patrons, which have become common in buffets, and which are
essentially retail food spaces and require special lighting.
2. Section 505.5.1 is amended to include exceptions to the calculation of total
connective interior lighting power needed to accommodate the special lighting needs of
gambling areas. Exceptions 1 through 5 are already part of the 2006 IECC. Exceptions
6 and 7 add exceptions for the "Front of House" of gambling facilities and display
kitchens. These exceptions are necessary to accommodate the additional lighting,
signage, displays, etc. that are expected and necessary in the design of gambling areas
and display kitchens.
3. Section 505.5.2 is revised to take into account the additional lighting power that
is needed for areas with high ceilings. While this is not a issue that is particular to the
gambling industry, we believe it is an issue that was overlooked by the drafters of the
2006 IECC and the amendment to Section 505.5.2 would benefit the design and
function of all buildings with high ceilings in which additional overhead lighting is needed
to safely illuminate such areas.
4. Section 505.5.6 adds additional exceptions to the exterior lighting efficiency
requirements to exempt exterior lighting using Light Emitting Diode (LED), neon and
cold cathode lighting sources and Front of House exterior lighting. These exceptions
are needed to accommodate the unique lighting sources typically used by gambling
properties (to the extent the use of neon, cold cathode, or LED would be permitted
under the Port of Dubuque Design Standards).
RECOMMENDATION: (recommend the 2006 International Energy Conservation Code
be adopted and that the amendments listed be adopted as well. I have attached an
ordinance for the City Council's use.
