FOREWORD
The International Energy Conservation Code, 2000 Edition, published by the International Codes Council and the Southern Building Code Congress International, Inc., when used in conjunction with these Georgia Supplements and Amendments, shall constitute the official Georgia State Energy Code for Buildings. For high-rise and non-residential structures, the International Energy Conservation Code adopts by reference American Society of Heating, Refrigerating, and Air Conditioning Engineers (ANSI/ASHRAE/IESNA) Standard 90.1-2001.
INTRODUCTION
This document supplements and amends The International Energy Conservation Code (IECC), 2000 Edition. In cases where there are differences between these "Supplements and Amendments" and the IECC, or with ANSI/ASHRAE/IESNA Standard 90.1-2001, these "Supplements and Amendments" shall take precedence.
Each Chapter of this document associates directly with the corresponding chapter of the IECC.
* Chapter 1: Administration and Enforcement.
* Chapter 2: Definitions.
* Chapter 3: Establishes the design criteria of the entire state of Georgia and defines the five climate zones. The climate zones establish the design conditions for use with chapters 4, 5, 6 and 8.
* Chapter 4: Pertains to residential building design by systems analysis, as well as the use of renewable resources such as wind, solar, geothermal, etc. Chapter 4 has only one amendment, 402.1.3.1.4, which establishes 0.40 as the minimum Solar Heat Gain Coefficient (SHGC) for all Climate Zones in Georgia.
* Chapter 5: Residential compliance by designed component1 performance, thereby analyzing the total building for compliance one component at a time. Assuming each individual component of the building meets the thermal requirements of the code then the entire building is deemed to comply. This chapter offers the use of "Tradeoffs" to achieve compliance by allowing the builder to substitute or "trade-off" values between building components. A properly executed "Georgia Trade-off Worksheet"2 or the use of appropriate computer software such as MECcheck3 may be used to validate any trade-off.
* Chapter 6: Offers prescriptive compliance via the Single Step Compliance Method by selecting an option directly from the charts in the correct climate zone. The values from the option show the minimum requirements for each component of a residential structure for the specific climate zone.
* Chapter 7: Pertains to building design for all commercial buildings, except those that comply with Chapter 8, the Single Step Compliance for Simple Commercial Buildings or appropriate computer software such as COMcheck4 may be used to validate compliance.
* Chapter 8: Pertains to design by acceptable practice for commercial buildings. Where differences between this document and the IECC, or ANSI/ASHRAE/IESNA Standard 90.1-2001 are noted, this document shall take precedence.
* Chapter 9: Pertains to reference standards, Figure 9-1, F2-Values for Slab-on-Grade and Figure 9-2, Group R Buildings, A-1 and A-2 Component R values/U factors.
* Appendix: Existing Appendix becomes "Appendix A" and adds a new Appendix B with updated Prescriptive methods and Trade-off methods to demonstrate compliance; including new Prescriptive Single Step Compliance Tables for most commercial buildings.
SUMMARY
In summary, Chapters 4, 5 and 6 offer different methods to achieve code compliance for low-rise residential construction and Chapters 7 and 8 offer different methods to achieve code compliance on commercial and high-rise residential construction. Appendix B provides additional prescriptive methods of showing compliance, some simple methods and forms to calculate and demonstrate compliance and some illustrations to help understand the code requirements. Individual structures should be addressed by a compliance method from a single chapter approach and not by a combination of compliance methods. The "basic requirements" of the IECC apply to all compliance methods.
Please note, the maximum 0.40 Solar Heat Gain Coefficient (SHGC) and maximum 0.65 U-factor required for residential windows 5 in this document shall become effective January 1, 2004. For the period of January 1, 2003 to December 31, 2003, the "Single Step" Residential Energy Code Compliance packages6 may be used to determine code compliance by disregarding the 0.40 SHGC requirement.
In dealing with the energy conservation requirements promulgated by this code, discussion of insulation R-values and component U-factors may appear to overshadow the matter of controlling air infiltration. Air infiltration accounts for substantial heat loss, heat gain, and moisture migration in a building. Proper sealing around all doors, windows, and other envelope penetrations through the walls, ceiling and foundations is as important to code compliance as is the installation of the proper R-value in a component. Proper sealing shall be done by the builder and inspected by the Building Official or Building Inspector.
It is not the intention of this code to abridge safety or health. There may be cases where conflicts occur between this code and other codes that are mandatory within the state. Provided safety, health, or environmental requirements under other applicable codes are not abridged, this code shall be enforced as written.

WINDOW PRODUCT RATING, CERTIFICATION, AND LABELING
The Georgia Energy Code, Section 102.5.2 requires that fenestration products, (window, glass door and skylight) shall be labeled with its U-factor and Solar Heat Gain Coefficient (SHGC). Fenestration products' U-factor and SHGC shall be determined by an accredited, independent laboratory in accordance with NFRC 100 for Ufactor and NFRC 200 for SHGC, or from default values from Table 102.5.2(1) for U-factor and Table 102.5.2(3) for SHGC. Manufacturers that label their products with NFRC U-factors and SHGCs shall either use an NFRC label (see sample NFRC label below) or a label of their own design. The label shall list as a minimum: U-factor, SHGC, frame type, number of panes of glazing, whether the window is fixed or operable, and the type of glazing tint, if present. The label shall contain the words "Meets Thermal Break Criteria" if the product claims a U-factor based on a thermal-break product.
National Fenestration Rating Council (NFRC) - U-factor and SHGC
Below is a sample window label of NFRC-determined energy performance values that code officials should look for during inspections:
Note: This sample window label also contains "Visible Transmittance" (VT) performance values. The Georgia Energy Code does not establish minimum requirements for VT, but this and other information that might be useful to builders, designers, consumers, and others (like air leakage rates) may also be present on labels used by some manufacturers.
Default U-factor and SHGC
If NFRC 100 or NFRC 200 are not used to determine product Ufactor and SHGC, then manufacturers shall obtain default values from Table 102.5.2(1) for U-factor and Table 102.5.2(3) for SHGC and label the product with a "Default Window Label." Manufacturers or assemblers shall label their products with default U-factors and SHGCs, for example, site built and shop assembled windows without NFRC labels, shall follow the format of the sample default label below. This label shall list as a minimum: Default U-factor from Table 102.5.2(1), Default SHGC from Table 102.5.2(3), frame type, number of panes of glazing, whether the window is fixed or operable, and the type of glazing tint, if present. The label shall contain the words,"Meets Thermal Break Criteria" if the product claims a U-factor based on a thermal-break product:

Appendix
BUILDING ENVELOPE
The elements of a building which enclose conditioned spaces through which thermal energy is capable of being transferred to or from the exterior or to or from spaces exempted by the provisions of Section 101.4.1. -2000 IECC
The building envelope is the barrier that separates the conditioned space from the outside or unconditioned spaces. The building envelope consists of two parts - an air barrier and a thermal barrier that must be both continuous and contiguous (touching each other). In a typical residence, the building envelope consists of the roof, walls, windows, doors, and foundation. Examples of unconditioned spaces include attics, vented crawlspaces, basements with ceiling insulation and no HVAC supply registers, and garages.
* Note: An attic knee wall is any vertical wall that separates conditioned space from an unconditioned attic. In Georgia, knee walls must be insulated to R-19. An attic-side air barrier (OSB, foil-faced sheathing, etc.) is recommended.
** Note: Although there is nothing to prevent the garage walls from being insulated, due to indoor air quality concerns, the garage should never be considered inside the building envelope.
"SINGLE-STEP" COMPLIANCE
FOR SIMPLE COMMERCIAL BUILDINGS
The Single-Step compliance procedure is available only for small commercial buildings with simple HVAC systems. If you demonstrate that your building complies with this procedure, you are deemed to comply with the Georgia State Energy Code. You shall complete the documentation on all of the enclosed forms for Envelope, Lighting, and HVAC and Water Heating systems and equipment.
Eligible buildings shall meet all of the following requirements:
1) Two stories or less.
2) 25,000 ft2 or less gross floor area.
3) Maximum glazing area is 25% of the above-grade gross wall area.
4) Each HVAC system serves a single zone, controlled by a single thermostat in the zone being served.
5) Cooling (if any) is provided by one or more air-cooled (unitary packaged or split system) air conditioners or geothermal heat pumps that do not exceed 20 tons (each).*
6) Primary heating (if any) is provided by one or more air-cooled (unitary packaged or split system) heat pumps (with internal supplemental electrical resistance heat, if needed), geothermal heat pumps, or fuel-fired furnaces. Supplemental individual electric resistance heaters are limited to a maximum of 5 kW each.*
7) The outside air quality is 3,000 cfm or less and shall be less than 70% of the total supply air.
* Note: Hydronic or steam distribution systems are not permitted under this Single Step approach.
Failure to meet all of the above criteria precludes use of the Single Step compliance forms. All other commercial buildings shall demonstrate compliance with any of the other compliance pathways of the Georgia State Energy Code for commercial buildings, and include submittal of proof of compliance.
