Design Criteria
ASHRAE Zones 2A / 3A / 4A
hot-humid to mixed-humid
Georgia spans three climate zones, from hot-humid coastal Savannah through mixed-humid Atlanta to the cooler north Georgia mountains. A design sized for one end of the state is wrong at the other, and dehumidification drives equipment selection through most of the cooling season.

Plan Review Notes
Georgia adopts State Minimum Standard Codes through the Department of Community Affairs, and the mandatory codes apply to construction statewide whether or not a local government elects to enforce them. That makes the base requirements consistent across jurisdictions, though local governments handle plan review and inspection and may adopt the optional codes and appendices on top.
Georgia moved to the 2024 editions of the building, mechanical, plumbing, and fuel gas codes, plus the 2023 National Electrical Code, effective January 1, 2026. That is an unusually current code cycle, and drawings coordinated to the previous editions will read as out of date to a Georgia plan reviewer.
The exception worth planning around is energy. Georgia did not move its energy code in that wave: commercial work is still held to the 2015 International Energy Conservation Code with Georgia supplements, so envelope assumptions and equipment efficiency minimums follow an older standard than the rest of the set. Every Georgia deliverable True Power Systems issues is sealed by a Professional Engineer licensed in the state.
Services Schedule · Georgia
Full MEP scope under one roof, scheduled the way you'd schedule equipment. Every line ships sealed by a Georgia-licensed PE.
| Mark | Service | Scope | Basis of design |
|---|---|---|---|
| M-1 | Mechanical & HVAC Design | Load and ventilation design, ductwork and air distribution, control sequences, and energy modeling. Sized for the Georgia climate rather than a rule of thumb, with equipment schedules a contractor can actually buy from. | 2024 International Mechanical Code · ASHRAE 62.1 · ASHRAE 90.1 |
| E-1 | Electrical Design | Power distribution, lighting and branch circuiting, service and gear sizing, emergency and standby power, and EV charging infrastructure. Documented so the electrical contractor is not guessing at intent. | 2023 National Electrical Code · NECA |
| P-1 | Plumbing Design | Domestic water and sanitary, hot water recirculation, natural gas and propane piping, specialty and process piping, and compressed air. Designed to the code Georgia actually enforces, which is not always the model code. | 2024 International Plumbing Code |
| C-1 | Revit & BIM Coordination | Modeled in Revit and coordinated against the architectural and structural models, with clash detection run before the drawings leave our office. Conflicts get resolved on screen instead of in the ceiling. | Revit · AutoCAD MEP · Bluebeam |
| ES-1 | Power System Studies | Arc flash, short-circuit, coordination, harmonic, and load flow studies when a Georgia project needs the electrical design backed by analysis. The same engineers who design the system model it. | NFPA 70E · IEEE 1584 · IEEE 519 |
| CA-1 | Construction Support | Shop drawing review, RFI response, utility coordination, field observation, and commissioning support. We stay on the project after the permit set, because that is when most of the questions arrive. | Construction administration |

Construction administration
Legend · Who We Work With
If your work touches buildings in Georgia, one of these is you. Architects lead most of our engagements; contractors and owners come to us directly just as often.
We run the MEP scope as a consultant to the architect on Georgia projects, from concept through construction administration. One engineering team across mechanical, electrical, and plumbing, coordinated in your model.
MEP design for Georgia ground-up projects, tenant fit-outs, and building repositioning. We size systems against a real pro forma, so the mechanical scope is not the line item that blows the budget at bid.
Engineering support for Georgia mechanical and plumbing contractors who need sealed drawings, load calculations, or equipment selection on a design-build job. We work to your means and methods rather than against them.
Process-support HVAC, industrial ventilation and dust collection, compressed air, and process piping for Georgia plants and food processing facilities. Designed around the production line, not around a template.
Cooling and power design for Georgia data centers and mission-critical rooms, including redundancy strategy, capacity planning, and the electrical analysis that has to back the design.
MEP design for Georgia healthcare, K-12, and higher education facilities, where ventilation requirements, pressure relationships, and life-safety systems drive the design and the review.

Keynotes · Why TPS
The reasons design teams keep us on the next project, keyed like notes on a plan.
A single engineering team carries all three disciplines, so coordination happens inside one office instead of across three subconsultants. One contract, one point of responsibility, one set.
We model in your environment and run clash detection against the architectural and structural models before drawings go out. Conflicts get resolved on screen, not in the ceiling.
The editions on sheet G-001 are what we design to, verified against the state’s own publication. Plan review goes smoother when the drawings and the reviewer read the same book.
Arc flash, short-circuit, and coordination studies come from the same engineers who design the distribution. Most MEP firms sub this out; we consider it part of the electrical scope.
Shop drawing review, RFI response, and field observation are in the fee, because most of a project’s hard questions arrive during construction, not design.

General Notes · Georgia
The questions Georgia design teams and owners ask before they hire us, answered the way we'd note them on a set.
Georgia enforces the 2024 International Mechanical Code with 2026 Georgia Amendments, adopted as a State Minimum Standard Code by the Department of Community Affairs and effective January 1, 2026. It applies statewide whether or not the local government enforces it.
Yes. Georgia adopts the 2024 International Plumbing Code with 2026 Georgia Amendments as a mandatory State Minimum Standard Code. The Georgia amendments take precedence where they conflict with the model code, so a design coordinated to the unamended IPC is not automatically compliant.
Commercial buildings in Georgia are held to the 2015 International Energy Conservation Code with Georgia supplements and amendments. Georgia moved its building, mechanical, plumbing, and electrical codes to newer editions effective January 1, 2026 but left the energy code on the 2015 edition, so the energy analysis follows an older standard than the rest of the set.
Georgia spans ASHRAE climate zones 2A through 4A, from hot-humid on the coast near Savannah through mixed-humid in Atlanta to the cooler north Georgia mountains. Equipment sized for Atlanta is not correct in Savannah, and latent load and dehumidification control drive selection through most of the state.
Construction documents used for permit must be sealed by a Professional Engineer licensed in the State of Georgia. True Power Systems holds an active Georgia PE license and stamps every Georgia deliverable.
Yes. Most of our work comes in as a consultant to the architect, carrying mechanical, electrical, and plumbing design from concept through construction administration. We model in Revit and coordinate against the architectural and structural models so conflicts surface before they reach the field.
