##  RESNET Update

**DOE Building Energy Codes Conference **
**Denver, Colorado**

## Need to Shift Thinking to Optimized Systems Engineering 

**Most Builders Rely on Compliance With Minimum Prescriptive Codes**
**This results in:**
**    ****Missing Integrated Solutions That Address System ****	****Interactions**
**Optimized System Strategies Will Result in:****	**
**    ****Higher Levels of Energy Efficiency**
**     ****Efficient Use of Resources**
**     ****Greater Durability**
**     ****Improved Comfort**
**     ****Greater Long Term Value to Consumer****	**

## Performance Method 

**+****	****Recognizes and Rewards Innovation**
**+****	****Gives Builder Greatest Flexibility to ****	****Incorporate Most Cost Effective ****	****Features That Makes Most Sense in the ****	****Local Housing Market**** **
**+****	****Construction Savings More Than Makes ****	****Up for Cost of Verification**

## Performance Method

**	****Where Viable Option Builders Will Choose Performance**
**2004 ENERGY STAR Homes Verification (131,763 Homes)**
**93% Performance Based (HERS)**
** ****7% Prescriptive Based****	**

## Major Changes in 2006 

**+   13 SEER Air Conditioner Standard**
**+   HERS Basis on Total Energy Use of Home**
**+   RESNET Standard Based on DOE RICC Proposal **
**     ****Embodied in 2004 IECC**
** ****+   New HERS Index**
**+    Insulation Installation Inspection Procedures**
**+    Federal Tax Credit for Homes 50% More Efficient    **
**      ****than IECC**

## Rating Expanded Score 

**Whole Energy Use of Home**
**+****	****Heating**
**+****	****Cooling **
**+****	****Water Heating**
**+****	****Appliances**
**+****	****On-Site Power Production**

## New HERS Index

**Change Rating Score to “HERS Index”**
**0 = Net Zero Energy Home**
**100 =****	**** HERS Reference Home (2006 IECC)**

## HERS Index

**Why?**
**Dynamic Changes in 2006 – No longer can compare scores**
**New Homes Scores Were Compressed in Old 80 Based Score**
**New Index More Intuitive – Consumers can readily understand**

## Insulation Inspection Procedures

**Three Ratings of Quality of Insulation Installation**
**Can only receive lowest rating if rater does not inspect insulation installation**

## Effective Date of Changes

**July 1, 2006**
**Tracks with ENERGY STAR Changes**

## Looking Around the Corner

**+****	****National Test Specifications for ****	****Software Programs to Calculate ****	****Performance Verification to the ****	****IECC**
**+****	****White Tags**

## RESNET IECC Software Specifications

**+****	****Auto-Generation of the Reference Home ****	****(IECC Performance Specifications)**
**+****	****Loads Calculation**
**+****	****RESNET HVAC Tests**
**+****	****Duct Distribution System Efficiencies ****	****Tests**
**+****	****Water Heating Efficiencies**

## White Tags

**Follow-up to Renewable Energy Certificates  ****State Sets Production Targets to Meet and Credits Can Be Bough or Sold - $900 Million Traded in 2005**

## White Tags

**States That Have Already Adopted:**
**+****	****Connecticut**
**+****	****Nevada**
**+****	****Pennsylvania**
**Nine additional States Actively Investigating Setting Energy Efficiency Portfolio Requirements**

## White Tags

**Nevada**
**25% of Required Savings Must Come From the Residential Sector**
