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 for 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 "Trade-offs" to achieve compliance by allowing the builder to substitute or "trade-off" values between building components. A properly executed "Georgia Trade-off Worksheet2" 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 COMcheck4may 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 92, 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.

GA State Energy Code for Buildings (International Energy Conservation Code) Amendments 2003

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 Ufactor required for residential windows5 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.
GEORGIA STATE AMENDMENTS
CODE REFERENCE: Change all references from ASHRAE/IESNA 90.1-1999 to ANSI/ASHRAE/IESNA 90.1-2001 respectively.
APPENDICES: Appendices are not enforceable unless they are specifically referenced in the body of the code or adopted for enforcement in the ordinance of the authority having jurisdiction.

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 U-factor 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: Ufactor, 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:

Fig. 102.5.2
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 and NFRC 200 are not used to determine product U-factor 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:

You are "deemed to comply" with the Georgia State Energy Code for Buildings if your residential structure meets the following conditions:

1. Your building shall be a one or two family detached dwelling built using wood framing. 2. Your building is three stories or less in height and not larger than 5,000 square feet of conditioned area. 3. Your building site must be located in Climate Zone 4B, as shown in the IECC 2000 Figure 302.1(11), an area of
the state where the climatic conditions of approximately 2,000 Heating Degree Days or less apply. 4. You shall not make any substitutions of any kind for R-values/U-factors listed below. 5. Your window and door openings shall not exceed 18 percent of the gross wall area. 6. You shall comply with code requirements for envelope air sealing including all air tight, I. C. rated light fixtures
in ceilings with attics and seal all ductwork with mastic. 7. Equipment minimum efficiencies shall be observed:

Foam Plastics shall not be installed below grade on foundation walls or below grade on slab foundations. These Rvalues may result in some degree of "over-design". However, this method will apply to a majority of one and two family residences built in South Georgia. If you must change one or more of the R-values/U-factors listed to a lower R-value or higher U-factor, then do not use this method. No substitutions are allowed here.
Instead, you may use one of the other methods to show compliance, such as The Tradeoff Worksheet or the free MECcheck software (available at www.energycodes.gov). You may also use one of the Chapter 4, 5, or 6 approaches of the 2000 IECC with Georgia modifications.
At the time a permit is requested, you shall show how you plan to meet the Georgia Energy Code. When using the "Single-Step" Residential Energy Code Compliance method, you may not be required to turn in additional paperwork to obtain a building permit. _____________________________________________________________________________________ Note 1: "% Openings" is defined by the total area of the openings of windows and doors divided by the total gross area of the
exterior wall. % Openings = 100 x (windows + doors) / (opaque walls + windows + doors). Note 2: Up to 5% of the window area may be exempt from meeting the window U-factor and SHGC requirements to allow for
decorative glazing. Note 3: Sloped ceilings, such as cathedral & tray ceilings, which require batt insulation, may be insulated with R-19 batts,
provided the R-19 portion does not exceed 25% of the total ceiling area and provided the flat portions of the ceiling are insulated to R-30. Note 4: Insulating values for plywood, OSB or other structural sheathing are already accounted for in the approach. Garage walls may be R-13 cavity insulation with gypsum on both sides.

"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 electric 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 quantity 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.

Example 2: Ten windows (each 4' x 8') on front faade: Clear glazing SHGC =0.70 with PF = 0.33. Sides of building have twenty windows (each 6' x 6') with no overhang but low-e coating with SHGC = 0.34. Gross wall area is 4,300 sq. ft.

Determine Percent Glazing:

10 x (4 x 8) = 320 sq. ft. plus 20 x (6 x 6) = 720 sq. ft.

Total: 1,040 sq. ft.

Window to Wall Ratio (WWR): 100 x (1,040 sq. ft / 4,300 sq. ft.) = 24.2% (less than 25%)

Determine Weighted Average Fenestration SHGC for whole building: Use the PF chart for the front windows for PF = 0.33 (between 0.3 and 0.4). Multiplier is 0.74 SHGCfront fenestration = SHGCglazing x SHGCMultiplier = 0.70 x 0.74 = 0.52 SHGCside fenestration = 0.34 SHGCavg = (A1 x SHGC1 + A2 x SHGC2) / ATotal =
