**2004 National Workshop on State Building Energy Codes**

**Notes:**
Good morning/afternoon/evening.

[INTRODUCE SELF]

I’m here today to talk to you about the

CONOVER - WHAT IS THE LOUISIANA PARTNERSHIP?  IF EVERYONE KNOWS WHAT THAT IS THEN GREAT.  IF NOT THEN MAYBE COME UP WITH SOMETHING ELSE THAT CONVEYS WHAT YOU ARE TALKING ABOUT.  ALSO IF THAT TITLE REMAINS THEN CAN I ASSUME THERE WILL BE 49 OTHER STATE PARTNERSHIPS?

## INTERNATIONAL CODE COUNCIL

**INTERNATIONAL CODE COUNCIL**

**Mission:  to develop a comprehensive and compatible regulatory system for the built environment ...**

**Not Just Codes but a Complete Building Regulatory System**** **

## Agenda 

**Overview of the ICC**
**ICC code development process**
**Energy related changes in the IECC**
**Changes in the IRC**

**Notes:**
I LIKE THE TERM BUILT ENVIORNMENT AND NOT BUILDINGS AND STRUCTURES.  JUST MY PREFERENCE TO USE WHAT I THINK IS A BROADER TERM.  CAN’T YOU SUM THIS UP - AND MAYBE YOU DO IN THE VERBAL REMARKS  AS - ONE SET OF REQUIREMENTS NATIONWIDE AND ONE PLACE TO GO FOR ALL THE TECHNICAL SUPPORT NEEDED TO ADOPT AND IMPLEMENT THE USE OF SUCH REQUIREMENTS.

## Expected Outcome 

**A better understanding of the ICC and ICC code development process**
**A better understanding of how the 2004 Supplement to the 2003 IECC and energy provisions of the 2003 IRC differ with the 2003 IECC and IRC**

## ICC Overview

**Over 300 highly trained staff in 15 U.S. and 2 international locations**
**Widespread recognition throughout the U.S.**
**A history of support for public health, safety and welfare **

**Notes:**
SAY THIS UP FRONT TO GET THEIR ATTENTION THAT YOU DID NOT JUST COME OUT FROM A ROCK YESTERDAY.  THE LAST SLIDE SHOULD BE THE TEAR JERKER THAT LEAVES THEM SAYING THAT THEY NEED TO GO WITH THE ICC TO ADDRESS THE NEEDS OF THEIR CITIZENS.

## ICC Code Support Infrastructure

**Conformity Assessment**
**Testing, Quality Assurance and Fabrication**
**Building Technology Evaluation**
**Codes and Standards Support Services**
**Personnel Certification**
**Professional Development Services**
**Membership Services**

***ICC’s fulfills it’s mission of ensuring public safety with a support infrastructure that no one else offers and which  facilitates the ease of application and use of the codes***

**Notes:**
GREAT.  WHAT ELSE DID YOU FORGET.  PLAN REVIEW, SPEAKERS, ETC.?  DELETE EVALUATION AND ACCREDIATION AND SIMPLY SAY CONFORMITY ASSESSMENT.  HOW ABOUT ALL YOUR REGIONAL OFFICES.  HOW ABOUT THE COMITTMENT AND PARTICIPATION OF YOUR CODE OFFICIAL MEMBERS AS LOCAL POINTS OF CONTACT.

## ICC Code Development

**Any person, corporation or entity can participate**
**Regulatory-based consensus**
**Predictable agenda**
**Two cycles every three years**
**Two hearings per cycle**

## EC 48-03/04

**Buildings can now meet IECC or IRC regardless of window area (used to limit IRC use 15% WWR for single family and 25% WWR for townhouses)**
**When an R-value is marked on the insulation it must be applied by the manufacturer to each piece of insulation 12 in. wide (used to simply say on each piece of insulation)**

**Provides simplified insulation R-value and fenestration requirements by component for one of 8 climate zones (instead of 17) regardless of window area (used to be 15%WWR for SFD and 25% for townhouses)**
**Adds a compliance path that provides equivalent U-factors for envelope assemblies**
**Adds a compliance path that is based on a total building UA equivalent **
