ONE NEW MANDATORY CODE, TWO NEW PERMISSIVE CODES AND NEW GEORGIA AMENDMENTS TO BECOME EFFECTIVE JANUARY 1, 2015
On November 5, 2014 the Department of Community Affairs (DCA) Board, on the recommendation of the State Codes Advisory Committee (SCAC), adopted the 2014 Edition of the National Electrical Code (NEC) with no GA Amendments to replace the currently adopted 2011 NEC, as the mandatory Georgia State Minimum Standard Electrical Code. The Board also approved the adoption of the 2012 Editions of the International Property Maintenance Code (IPMC) and International Existing Building Code (IEBC), both with GA Amendments to replace currently adopted 2006 editions of these codes as permissive State Minimum Standard Codes. In addition to adopting the above codes the board also approved the adoption of GA Amendments to the following codes: the International Residential Code (IRC), International Building Code (IBC), International Plumbing Code (IPC), International Mechanical Code (IMC), International Fuel Gas Code (IFGC) and Residential Prescriptive Deck Detail.
These new codes and Georgia Amendments will become effective on January 1, 2015. There will be a one year delay for the amendments to the Yellow Pine span tables in the IBC, IRC, and Residential Prescriptive Deck Detail. The delayed amendments to the Yellow Pine span tables will become effective January 1, 2016. The new 2015 Georgia Amendments are available on the Department of Community Affairs webpage at the below link:

OFFICE OF CONSTRUCTION CODES WINS "EXCEEDING EXCELLENCE" AWARD! L to R: Traci Turgeon, Ted Miltiades, Max Rietschier, Bill Towson, Commissioner Gretchen Corbin, John Watts and Dee Leclair.
Department of Community Affair's "Exceeding Excellence" award reinforces the state's Faster, Friendlier, Easier customer service initiative. This quarterly honor recognizes employees who show exemplary customer service by going above and beyond their required job duties.
The 4th quarter 2013 award honors the Office of Construction Codes, in the Community Development Division.
When a carbon monoxide leak at an Atlanta elementary school made dozens of children and adults sick, Governor Nathan Deal called on DCA to study the problem and make recommendations. The assignment fell to the Office of Construction Codes, led by Ted Miltiades, and his team, consisting of Max Rietschier, Bill Towson, Dee Leclair, Calvin Jordan, John Watts and Traci Turgeon.
Although the assignment added to an already very busy calendar of code reviews then under way, Ted's group quickly assembled a task force of experts in the field, along with school leaders, utility representatives and safety officials. Using the existing structure of DCA's State Codes Advisory Committee, in conjunction with the State Fire Marshal and the Department of Education, and with the support of Ted's staff, this group examined every angle of the problem of carbon monoxide in schools.
The Office of Construction Codes assembled and published the group's recommendations in time for the beginning of the 2013 school year. Their work gave local officials and educators the authoritative research they needed to make responsible policy decisions about how to manage the risk of carbon monoxide in schools. The report is available on the DCA website on the Office of Construction Codes Publications page.
The nomination for the Office of Construction Codes stated, "the work of the task force and Ted's staff was an excellent example of government responding effectively to an important public safety issue."
As "Exceeding Excellence" winners, the Construction Codes team received agency-wide recognition and lunch with Commissioner Corbin.

SCAC SUBCOMMITTEE APPOINTED TO REVIEW 2012 INTERNATIONAL WILDLAND-URBAN INTERFACE CODE
At the last meeting of the State Codes Advisory Committee (SCAC) held on July 24, SCAC Chairman Bill Guinade appointed a Subcommittee to review and consider the 2012 International Wildland Urban Interface Code (IWUIC) for adoption as a new Permissive State Minimum Standard Code with any proposed GA State Amendments.
The purpose of the IWUIC is to mitigate the hazards to life and property from the intrusion of fire from wildland exposures and fire from adjacent structures and preventing structure fires from spreading to wildland fuels. This code will be strictly voluntary and must be adopted by local ordinance to be enforced. It is intended to apply to the construction, alteration, movement, repair, maintenance and use of any new buildings, structures or premises within Wildland Urban Interface Areas that are recorded on maps declared by local jurisdictions.
Seven SCAC members were appointed to serve on the 2012 IWUIC Subcommittee:
1. Bill Duck, Chairman, representing State Building Officials
2. David Adams, Vice Chairman, representing State Fire Officials
3. Dwayne Garriss, representing State Insurance and Fire Safety Commissioner
4. Morgan Wheeler, representing State Building Officials
5. Tim Williams, representing Licensed Home Builders
6. Bill Lusk, representing Licensed General Contractors
7. Ryan Taylor, representing Professional Architects
The first meeting of the 2012 IWUIC SCAC Subcommittee will be held on Thursday, January 22, 2015 at 10:00 AM in Room 302 of the GA Department of Community Affairs (DCA) located at 60 Executive Park South, NE, Atlanta, GA 30329. This meeting is open to the public and any interested parties are invited to attend. Should you have any questions or wish to be included on the interested parties list, please contact Bill Towson, DCA Staff Liaison, directly at (404) 679-3109 or bill.towson@dca.ga.gov.

NEW DOE EFFICIENCY STANDARDS FOR RESIDENTIAL HVAC APPLIANCES
The US Department of Energy (DOE) recently updated the federally mandated minimum efficiency standards required for residential HVAC appliances. The new regional standards for residential non-weatherized furnaces went into effect on May 1, 2013 and the new regional standards for residential weatherized furnaces and residential central air conditioners and heat pumps will take effect on January 1, 2015. The new changes in the federally mandated standards will impact the efficiency and performance of HVAC equipment that is manufactured on or after these dates.
What Will Be Affected by the New Standards?
Seasonal energy efficiency ratio The SEER expresses the relative consumption of electrical energy in ratio to BTUs of heat extracted by an air conditioner or heat pump. The higher the SEER rating, the more energy-efficient the air conditioner.
Annual fuel utilization efficiency AFUE is a percentage that denotes the amount of furnace fuel consumption that actually produces heat. The higher the AFUE percentage, the more efficient the furnace.
Heating seasonal performance factor HSPF relates to the heating function of heat pumps, comparing the amount of heat output in BTUs to the amount of electricity consumed in watts. A high HSPF means more heat for less electricity.
What are the Efficiency Changes?
Split System Air Conditioners: Starting January 1, 2015, split system central air conditioners installed in the Southeastern Region must be at least 14 SEER. The Southeastern Region includes: Alabama, Arkansas, DOEDelaware, Florida, Georgia, Hawaii, Kentucky, Louisiana, Maryland, Mississippi, North Carolina, Oklahoma, South Carolina, Tennessee, Texas, and Virginia.
Heat Pumps: Starting January 1, 2015, the new minimum efficiency standard for split system heat pumps is 14 SEER and 8.2 HSPF. There are no regional standards for heat pumps, just a single nationwide standard.
Non-weatherized Furnaces: Non-weatherized gas furnace and mobile home furnaces installed on or after May 1, 2013 must be at least 80% AFUE.
Changes will also come to the familiar yellow EnergyGuide label attached to heating and cooling systems. For A/C and heat pump systems, the label will now display a range of potential SEER ratings instead of a single SEER. The range will represent highest and lowest possible SEER ratings depending upon the coil options included with the system.
For questions and information about the new federal HVAC equipment efficiency standards, visit DOE's webpage at http:// www1.eere.energy.gov/buildings/ appliance_standards/product.aspx/ productid/75.

The goal of this three-year study is to demonstrate whether investment in education, training, and outreach programs can produce a significant, measurable change in single-family detached home energy savings. The project is separated into three phases:
Phase I (6-9 months, early 2015): The study will begin with the project team traveling around the state to visit homes under construction. These observations will be compiled to understand how much energy an average brand new Georgia home will use upon completion. If the average new Georgia home uses more energy than anticipated, based on the current energy code, the project will move to Phase II.
Phase II (18-24 months, mid 2015 late 2017): The project team will implement targeted training, education and outreach based on observations in Phase I and energy code feedback from the construction industry. Targeted efforts will focus on groups including but not limited to builders, trades, code officials, architects and engineers.
Phase III (6 months, late 2017): The study will conclude with the project team visiting additional new homes under construction to determine if the amount of energy an average new Georgia home is less than when the study began.
The goal of this project is to support the regions residential construction industry. Working together we can realize the following benefits for Georgia's residential market:
Targeted energy code-specific education, outreach and support to meet the Georgia construction industry needs.
C onsistency of energy code implementation and enforcement across Georgia.
Assurance to homebuyers of Georgia that their new homes are energy efficient.
Important items to note:
Information from individual homes visited will be confidential.
Permit holders will be contacted before the project team visits a selected home.
Only homes that have not yet received a Certificate of Occupancy will be visited.
Homes will only be visited once during the entire study.
In early 2015, the project team will be holding 3 regional stakeholder meetings to collect feedback on the current energy code. Please stay tuned for dates and locations. If you have interest in attending a stakeholder meeting or any questions or feedback regarding the study, please contact Lauren Westmoreland, SEEA Energy Codes Manager, at LWestmoreland@ seealliance.org.

GEORGIA'S INDUSTRIALIZED BUILDINGS ADVISORY COMMITTEE MEETS AT FIRST STRING SPACE IN PEARSON First String Space, Inc., recently hosted a meeting of the Georgia Department of Community Affairs (DCA), Industrialized Buildings Advisory Committee (IBAC) on May 13, 2014 at their manufacturing facilities located in Pearson, GA. Jonathan Wright, President of First String Space (FSS), guided IBAC members, DCA staff and guests on a tour of their plant followed by a luncheon and business meeting. GA's Industrialized Buildings (IB) Program was created by the Industrialized Buildings Act (1976) for the purpose of establishing construction standards for residential and commercial buildings that are mass-produced in factories and then transported to building sites for erection and installation. DCA has the overall responsibility for the administration and enforcement of the program. To assist in this responsibility, an eleven-member Industrialized Buildings Advisory Committee, with representation from manufacturers, third party agencies, local government and the construction trades and professions, advises DCA Commissioner Gretchen Corbin on the program's rules and regulations. Manufacturers are required to obtain state approval for their manufacturing systems and quality control procedures. Every industrialized building is fully inspected during the open construction phase at the approved manufacturing facility. Inspection is accomplished by independent third party agencies which utilize private engineers and construction experts. All state-approved Industrialized (Modular) Buildings must be manufactured to meet State Minimum Standard Codes for Construction as adopted and amended by DCA. These buildings are required to have a DCA insignia affixed to each module or unit. The insignia certifies the unit is deemed to comply with the state's construction codes and rules for its intended application and use. However, local governments retain full control over all matters relating to a building's installation at a site, including subdivision controls, zoning issues, site grading, foundation installations and utility hook-ups. GA's Industrialized Buildings Program provides a mechanism whereby local building inspection departments can be assured that quality buildings are being installed in their jurisdiction. It also provides a cost effective means whereby manufacturers can have their buildings inspected during the manufacturing process. And, it establishes a set of minimum construction standards to safeguard the public safety, health and welfare of the citizens of Georgia. First String Space began production in 2007 and quickly made its mark as a high quality manufacturer within the modular industry. Their plant is located at 892 Railroad Ave. in Pearson, GA and has 143,200 total sq. ft. on 10 acres of asphalt with 13 additional acres of module storage. Employing approximately 150 employees, First String Space is a wholesale industrialized buildings manufacturer that markets its products through a dealer network within the modular industry. For more information about First String Space, call 912-422-6455 or visit www.firststringspace.com. For questions about GA's Industrialized Buildings Program, please visit www.dca.ga.gov or contact the Department of Community Affairs at 404-679-3118 or by email at industrializedbuildings@dca.ga.gov.

NEW SOUTHERN PINE DESIGN VALUE CHANGES UPDATED SPAN TABLES

The American Lumber Standard Committee (ALSC) Board of Review approved new design values for all sizes and grades of visually graded Southern Pine dimensional lumber. ALSC administers the American Lumber Standard System which provides the basis for acceptance of lumber and design values of wood species referenced in the International Building Code and the International Residential Code. The new design values for Southern Pine became effective on July 1, 2013.
As a result, the span tables in the 2012 IBC and 2012 IRC and 2014 GA Prescriptive Deck Details have been updated by GA state code amendments to reflect the new design values for Southern Pine. These GA amendments become effective on January 1, 2015, however, the span table changes have a delayed implementation date of January 1, 2016. The delay allows for a transitional period for designers, contractors and material suppliers.
The new design values only apply to new construction; not to any existing construction. This includes ceiling and floor joist, rafter and header spans. Like other building materials, wood products must meet the current building code requirements enforced at the time of construction. The integrity of any existing structures designed and built using the design values required by any previous code editions that were applicable at the time of permitting, does not change.
The American Wood Council (AWC) has also revised its standards and design tools, and developed addenda to assist with local building code enforcement. AWC's National Design Specification (NDS) for Wood Construction and Wood Frame Construction Manual (WFCM) for One- and Two-Family Dwellings have been updated to reflect these changes. Both are referenced in the current 2012 IBC and 2012 IRC and may be used by designers at anytime.
For more information about the new design values for Southern Pine visit www.spib.org or www.southernpine.com. A very helpful Questions and Answers document is available at http://www.southernpine.com/media/QA_NDVs_060113.pdf. For more information about the AWC reference standards, contact the AWC helpdesk at 202-463-4713 or info@awc.org.
Copies of the 2015 GA Amendments to the 2012 IBC, 2012 IRC and the 2014 GA Prescriptive Deck Details are available to download free from DCA's webpage located at: http://www.dca.state.ga.us/development/constructioncodes/programs/codeamendments.asp. If you need further assistance regarding the GA Amendments or the updated span tables, contact the Construction Codes Office at 404-679-3118 or by email at codes@dca.ga.gov.

Q: Is the Georgia Prescriptive Deck Detail for the International Residential Code the only allowed way to build a deck?
A: No, the Prescriptive Deck Detail is one compliance path for building a deck. The other compliance path is to use the provisions throughout the IRC that are applicable to the components that make up the deck. Once a compliance path is chosen the provisions of the chosen compliance path are mandatory.
