**Building Energy Code****Implementation**

**(One size fits all??)**

- 3/26/99

## Background - DOE

- The Energy Conservation and Production Act (Section 304) Requires DOE to:
- Make a determination as to whether revisions to the _IECC_ would improve energy efficiency in _residential_ buildings
- Make a determination as to whether revisions to _ASHRAE/IESNA Standard 90.1_ will improve energy efficiency in _commercial_ buildings
- Make determinations within a year

- 3/26/99

**Notes:**
Section 101 of the Energy Policy Act of 1992 (EPACT) amended Title III of the Energy Conservation and Production Act regarding building energy codes.
The International Energy Conservation Code (IECC) has been determined to be the successor to the Model energy Code (MEC)

## Background – States

- Upon a Positive determination, the Energy Conservation and Production Act (Section 304) Requires States to:
- Consider whether to update its residential building energy codes to meet or exceed the revised residential code
- Certify to DOE that it has held hearing and made a determination as to the appropriateness of updating its residential code
- Certify and demonstrate to DOE that it has updated its commercial building energy code to meet or exceed the revised commercial code
- Certifications are required within 2 years of the determination

- 3/26/99

**Notes:**
A State determining that it is not appropriate to update its residential code, must state why it is inappropriate. 

## Background – DOE

- DOE is required to provide technical assistance and financial assistance (incentive funding) to implement Section 304 of ECPA.

- 3/26/99

## Determination – Residential

**Determination – Residential**

- On January 10, 2001, a determination was made that the IECC 2000 would improve the efficiency of residential buildings
- Changes in the 2000 IECC that Improve Energy Efficiency and Compliance with the Code
- Protection of Above-grade Foam Insulation
- Solar Heat Gain Coefficient for Additions and Replacement Windows
- Construction Documents
- Definition of Roofs and Skylights
- Treatment of Partially Glazed Doors
- Use of Prescriptive Specification Compliance Tables with Steel-Framed and Masonry Walls

- 3/26/99

## Determination – Residential (cont)

**Determination – Residential**** (cont)**

- Changes in the 2000 IECC that Decrease Energy Efficiency
- Increase in U-value for Replacement Skylights
- Simplified IECC Chapter for Some Buildings
- Most of changes improve energy efficiency and make the code easier to use and interpret.
- The benefits of the changes outweigh the negative impacts.

- 3/26/99

## Determination – Commercial

**Determination – Commercial**

- DOE has performed both a quantitative and detailed textual analysis of Standard 90.1-1999 in preparation for making its determination
- There are changes we can quantify
- There are changes we cannot put a number on
- New administration reviewing analysis and staff recommendations
