The GEORGIA STATE ENERGY CODE FOR BUILDINGS (International Energy Conservation Code), 2000 Edition, published by the International Code Council, when used in conjunction with these Georgia Supplements and Amendments and the Georgia Supplements and Amendments adopted effective January 1 of 2003, shall constitute this official Georgia State Minimum Standard Code.
GEORGIA STATE AMENDMENTS
SCOPE:
Each chapter of these Georgia Supplements and Amendments corresponds with a chapter of the International Energy Conservation Code (IECC).
Chapter 1: Administration and Enforcement.
Chapter 2: Definitions.
Chapter 3: Design Conditions. 'The criteria of this chapter establish the design conditions for use with Chapters 4, 5, 6 and 8.'
Chapter 4: Residential Building Design by Systems Analysis and Design of Buildings Utilizing Renewable Energy Sources. 'This chapter establishes design criteria in terms of total energy use by a residential building, including all of its systems.' (One method by which to achieve compliance for low-rise residential construction.)
Chapter 5: Residential Building Design by Component1 Performance Approach. 'Residential buildings or portions thereof that enclose conditioned space shall be constructed to meet the requirements of this chapter.' (One method by which to achieve compliance for low-rise residential construction.)This chapter offers the use of 'trade-offs,' whereby values between building components may be substituted or traded-off for compliance. A properly completed Georgia Trade-Off Worksheet2 or the use of appropriate computer software (REScheck3) may be used to validate any trade-off.
Chapter 6: Simplified Prescriptive Requirements for Residential Buildings, Type A-1 and A-2. 'This chapter sets forth energy-efficiency-related requirements for the design and construction of Type A-1 and A-2 residential buildings.' (One method by which to achieve compliance for low-rise residential construction.)
Chapter 7: Building Design for All Commercial Buildings. Commercial buildings [except those that comply with Chapter 8, Design by Acceptable Practice for Commercial Buildings; the Single Step Compliance for Simple Commercial Buildings; or appropriate computer software (COMcheck3)] shall meet the requirements of ANSI/ASHRAE/IESNA Standard 90.1-2001. (One method by which to achieve compliance for commercial and high-rise residential construction.)
Chapter 8: Design by Acceptable Practice for Commercial Buildings. 'The requirements contained in this chapter are applicable to commercial buildings, or portions of commercial buildings.' (One method by which to achieve compliance for commercial and high-rise residential construction.)
Chapter 9: Referenced Standards.
Appendix A.
Appendix B. Provides additional prescriptive methods by which to achieve compliance, simple methods and forms to assist in compliance calculations, and illustrations to assist in the understanding of compliance requirements.
Individual structures should follow a single compliance method and not a combination of compliance methods. The 'basic requirements' of the International Energy Conservation Code (IECC) apply to all compliance methods.
Where these Georgia Supplements and Amendments conflict with either the International Energy Conservation Code (IECC)or ANSI/ASHRAE/IESNA Standard 90.1-2001, these Georgia Supplements and Amendments shall take precedence.
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 foundation is as important to code compliance as are proper insulation R-values and component U-values.
It is not the intention of this code to abridge safety or health. Where the International Energy Conservation Code (IECC) and these Georgia Supplements and Amendments conflict with other mandatory State Minimum Standard Codes, the International Energy Conservation Code (IECC) and these Georgia Supplements and Amendments shall be enforced as written provided safety, health or environmental requirements of other mandatory State Minimum Standard Codes are not abridged.
CODE REFERENCE:
(a) Replace all references to ASHRAE/IESNA 90.1-1999 with references to ANSI/ASHRAE/IESNA 90.1-2001.

Wall R-values shown in this chart are for the insulated (opaque) wall areas based on 25% framing factor (bands uninsulated); does not include any openings (windows and doors). Per FTC Regulation 16 CFR 460, the R-value of the insulation shall not be more than 10% below the R-value shown in a label, fact sheet, ad, or other promotional material for that insulation. R-values shown in labels, fact sheets, ads, or other promotional materials shall be rounded to the nearest tenth. However, R-values of 10 or more may be rounded to the nearest whole number. Therefore, an R-2 Foam shall be an aged/stabilized R-1.8 or higher, an R-3 Foam shall be an aged/stabilized R-2.7 or higher, an R-4 Foam shall be an aged/stabilized R-3.6 or higher and etc. For full details on LABELING AND ADVERTISING OF HOME INSULATION see: http://www.access.gpo.gov/nara/cfr/waisidx_03/16cfr460_03.html.

"Single-Step" Residential Energy Code Compliance
Climate Zone 8 - North Georgia - Option 8-OSB-2005-18%
You are "deemed to comply" with the Georgia State Energy Code for Buildings if your residential structure meets the following conditions:
100. Your building shall be a one or two family detached dwelling built using wood framing.
101. Your building is three stories or less in height and the above grade conditioned floor area is not larger than 5,000 sq. ft.
102. Your building site may be located in any Climate Zone, as shown in the IECC 2000 Figure 302.1(11).
103. You shall not make any substitutions of any kind for R-values/U-factors listed below in conditioned space.
104. Your window and door openings shall not exceed 18.0 percent of the gross wall area.
105. 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.
106. Equipment minimum efficiencies shall be observed:
Gas furnace: AFUE min 78%; A/C or Heat pump: SEER 10.0; Heat pump: HSPF 6.8; other (explain) ______
-% Openings in gross area of exterior wall1 | 18.0% Max. |
-Solid Doors Max. U-factor2 | 0.35 |
-Glazed Doors Max. U-factor2 | 0.43 |
-Windows2 | 0.43 |
-Solar Heat Gain Coefficient (SHGC) | 0.40 Max. |
-Ceiling insulation3 | R-30 |
-Wall cavity insulation4 | R-13 |
-Knee Wall cavity insulation | R-19 |
-Wall Sheathing 4 | OSB/Plywood |
-Floor Insulation (over unconditioned space) | R-19 |
-Basement Mass Wall insulation Min. | R-6 |
-Basement Stud Wall & Bands cavity insulation5 | R-11 |
-Slab Perimeter Insulation 6 | R-0 |
All R-values shall be printed on the actual insulation and be stabilized (aged) R-values.
All Windows shall have labels listing U-factor, SHGC, and Key Features.
Foam Plastics shall not be installed below grade on exterior side of foundation walls or below grade on slab foundations. These R-values may result in some degree of "over-design". However, this method will apply to a majority of one and two family residences built in 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 Trade-off Worksheet or the free REScheck 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, except calculation on Percent of Openings (Take-off Worksheet may be used to calculate % Openings).
________________________________________________________________________
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 - basement opaque walls).
Note 2: One Door or up to 5% of the opening area (whichever is greater area) may be exempt from meeting the window/door U-factor and SHGC requirements to allow for decorative glazing.
Note 3: Sloped ceilings, such as cathedral & tray ceilings, which require batt insulation, and space under HVAC equipment may be insulated with R-19 batts, provided the R-19 portion does not exceed 25% of the total ceiling area.
Note 4: Any combination of Cavity Insulation + Sheathing R-value that = R-13 or greater is permitted. 40% of the gross wall area and all basement walls, may be Plywood/OSB (for corner/structural requirements) or gypsum fastened direct to the garage wall studs.
Note 5: Unfinished conditioned basements require unfaced insulation, Class 1 facer (0-25 Flame Spread) or other approved insulation.
Note 6: Unheated slabs.
