## Winds of Change 

***“******Not Your Father’s ENERGY STAR Home”***
**2006 Will See Significant Changes to Home Energy Ratings and ENERGY STAR for Homes**

## Why? 

***New Environment in Residential Energy Efficiency***
*******	****Wide Spread Adoption of IECC**
**	****(Ratings & ENERGY STAR Based on MEC)**
*******	****2006 13 SEER Requirement**

## Comprehensive Enhancement of RESNET Rating Standards

**Standards Development Process**
**Two year drafting process**
**Proposal period open to all**
**All proposals considered by Drafting Committee**
**Pre-vetting offered to national groups**
**NAHB Energy Committee**
**U.S. Department of Energy**
**Environmental Protection Agency**
**Building America Team**
**National Association of State Energy Officials**
**75 Day Public Comment Process**

## Comprehensive Enhancement of RESNET Rating Standards

**Two Categories of Enhancements**
**Program Administration (Will not affect rating score) – Went into effect on April 1, 2005**
**Technical (Will impact how rating scores are calculated) – Goes into effect on January 1, 2006**

## Goals of Technical Enhancements

**Enhance the Technical Basis of Energy Ratings**
**Update Rating Standards to Bring Into Alignment with Current National Standards (IECC, Zero Energy Homes, Proposed Tax Credits)**

## HERS Reference Home

**	****REF: 2004-01 “Amending the Rating Reference Home”**
**Establishes the HERS Reference Home as equivalent to the DOE Residential IECC Code Change (RICC)**

## Expanded HERS Score

**	****EXP: 2004-01 “Incorporating lighting, appliances and on-site energy production in the rating score”**
**Establishes technical guidelines and procedures for expanding the rated features of the rated home.**

## What Does It Mean?

**	****Rates the Home’s Whole Energy Use**
**Aligns with U.S. Department of Energy’s Building America Program**

## Why Important?

**Whole Energy Use**
_**End Use**_**	****	****	**_**IECC Home**_** ****	**
**Heating/Cooling/****	****49%****	**
**Water Heating**
**Lighting****	****	****	****14%****	**
**Misc. Electric****	****	****37%**
**Soure:****	****NREL - 2005**

## Expanded HERS Score

**HERS “Expanded” score based on:**
**	**
**	****-****	****Heating, cooling, hot water, **
**	****-****	****Lighting and appliances, and **
**	****-****	****On-site power generation.**

## Insulation Inspection Procedures

**	****TECH: 2004-01 - Insulation Inspection Procedures**
**Provides procedures for assessing and applying insulation installation quality – Grades I, II and III**
**Establishes standards for grading insulation R-value due to compression.**

## Comprehensive Enhancement of RESNET Rating Standards

**	****Why the Buzz? **
**	****Rating Scores Will Go Down in 2006**
**	****-****	****Significantly in the cooling climates**

## Changes to ENERGY STAR for Homes Specifications 

**	****Why?**
**Wide Spread Adoption of IECC**
**2006 13 SEER Requirement**
**	****(Above changes could make current ENERGY STAR home below code in Miami)**
**RESNET Standards Changes**

## Changes to ENERGY STAR for Homes Specifications 

**	****Steps**
**Announced Proposal at 2005 RESNET Conference in March**
**60 Day Public Comment Process**
**Summit Meeting with RESNET Representatives**

## To Download Proposed Changes

## Changes to ENERGY STAR for Homes Specifications 

**Prescriptive Specifications**
**2004 IECC Insulation Levels**
**ENERGY STAR Qualified Heating, Cooling Equipment, Windows and Thermostat**
**Checklist of 12 Often-Missed Thermal and Air Barrier Locations to be Inspected by Raters (Thermal Bypass Checklist)**
**Maximum Allowable Levels for Envelope & Duct Leakage**
**A Minimum of Five ENERGY STAR Qualified Light Fixtures, Ceiling Fans, and/or Appliances**

## Changes to ENERGY STAR for Homes Specifications 

**Performance Specifications**
**The Performance Path will be Based on the New Expanded HERS Score **
**	****(EPA will be making a determination whether a single national score or multiple regional scores will be used and what the threshold rating scores will be)**

## Changes to ENERGY STAR for Homes Specifications 

**Potential Additional Performance Specifications**
**Within the performance path, EPA will require some combination of ENERGY STAR qualified products, as well as set maximum allowable levels for envelope and duct leakage (to be determined). **
**The Thermal Bypass Checklist**

## Changes to ENERGY STAR for Homes Specifications 

**Transition Period**
**EPA will establish a longer “grandfathering" period and make allowances for developments /contracts underway to aid the industry in moving smoothly to the new specification. **

## Changes to ENERGY STAR for Homes Specifications 

**What’s Next?**
**EPA will officially post the revised guidelines with proposed score thresholds, maximum allowable leakage numbers, and ENERGY STAR equipment options for comment on July 1 for a 3-week comment period**
**EPA plans to officially release the final new guidelines in early August**

## Changes to HERS and ENERGY STAR

**What It Means?**
**+****	****HERS, ENERGY STAR, IECC, Tax Credit, Building America Reference Home will be Aligned (Standardized Measurement of Home’s Energy Performance)**
**-****	****Rating Score/ENERGY STAR Will No Longer Track With Energy Code (Code = Heating / Cooling / Water Heating – HERS = Whole Energy Use)**

## Will Ratings/ENERGY STAR Still Have Relevance with Energy Codes?

**Yes**
**Base Line Reference Home Aligned (Chapter 4 - IECC 2004 Supplement)**
**Ratings Most Practical Tool for Performance Compliance Documentation (Accredited Rating Programs in 50 States)**
**Ratings Governed by National Consensus Standard and Involve Third Party Accreditation and Quality Assurance Review**
**Rating Software Programs Have Code Compliance Report (All versions of MEC and IECC)**** **
