Commercial HVAC Design Services
Engineered Load Calculations & Ductwork Layouts That Keep Your Projects Moving
At Elements Design Group, we specialize in commercial HVAC design for offices, retail, mixed-use buildings, tenant improvements, and light industrial spaces. Our designs are practical, permit-ready, and tailored to the real-world conditions commercial contractors face.
From complex Manual N calculations to code-compliant duct layouts using Manual Q design methods, our team delivers full mechanical documentation that aligns with your construction schedule, local code requirements, and equipment constraints.
What’s Included in Our Commercial HVAC Design Service
Each of our services is engineered for precision, code compliance, and clear documentation. We use industry-trusted tools like Wrightsoft and follow Manual J, D, S, N, and Q protocols to ensure everything is ready for submission and installation.
Explore our design solutions:
- Room-by-room Manual N Load Calculations
- Balanced Manual Q Duct Design with static pressure and friction loss metrics
- Code-specific COMcheck reports for energy compliance
- CAD/PDF duct layouts for plan sets
- Optional equipment matching (Manual S for light commercial systems using residential-grade equipment)
- Ready for submittal to AHJs, inspectors, or permitting offices
Whether you’re designing a retail space, office suite, or restaurant, we deliver professional HVAC design documents that help you build faster—with fewer rejections and no guesswork in the field.
Manual N (Commercial Load Calculation )
Room-by-room commercial load calculations that help you pass plan review, size your systems right the first time, and avoid costly delays.
Manual Q (Ductwork Sizing & Layout )
Balanced, performance-driven duct layouts that integrate static pressure drops, friction loss, and airflow balancing, engineered for optimal performance and easy approval.
COMcheck Report (Energy Code Compliance)
Fast and accurate reports tailored to your location’s IECC requirements , ensuring seamless energy code compliance and quicker permitting.

Frequently Asked Questions
It starts with a Manual N load calculation, where we determine the BTU/hr demand for each zone. Then, using Manual Q, we design ductwork that balances airflow to those spaces based on system pressure and friction loss. Finally, we confirm energy compliance with a COMcheck report tailored to your local code version.
At Elements Design Group, we use real project specs—roof type, window area, occupancy type, ventilation—so the design is buildable, not just theoretical.
This is an industry rule of thumb that says: if HVAC repairs exceed $5,000, you should consider full system replacement. While not directly related to system design, it reflects the importance of installing the right-sized, well-balanced system up front—something we ensure with our load and duct designs.
At its core, commercial HVAC design involves:
- Accurate load calculations (Manual N)
- Proper duct design (Manual Q)
- Code compliance (COMcheck or ASHRAE 90.1)
- Zoning and control strategies for usage patterns
- Equipment sizing and airflow balancing
Our services cover all the above with documentation ready for permitting and field use.
