Aermec Selection Program
vertical specialistApplied HVAC product selection software that includes air handling solutions within the Aermec portfolio.
Single-project workflow links AHU configuration inputs to coil and fan selection outputs for consistent report generation.
Aermec Selection Program is an AHU selection tool built around Aermec equipment libraries and project-based workflows. It supports end-to-end coil and fan selection outputs that designers can export as selection reports for downstream documentation.
The program focuses on matching airflow and psychrometric conditions to component selections, then producing reviewable results tied to the configured AHU. For teams that design specifically with Aermec product families, it reduces re-entry work by keeping selection inputs and outputs connected inside the same project.
- +Project-linked selection inputs keep calculations and report outputs consistent
- +Aermec product library coverage reduces manual data transcription during AHU design
- +Fan and coil selections are generated from the same airflow and condition settings
- +Selection report exports support typical design review and coordination workflows
- –Limited interoperability for non-Aermec equipment makes mixed-vendor AHU studies harder
- –Export outputs are report-centric and do not provide broad BIM-native handoff by default
- –Thermal and airflow modeling depth is narrower than tools that model full system assemblies
- –Requires repeat setup of component choices when AHU configuration variants are common

How to Choose the Right Ahu Selection Software
We separate options in ahu selection software by how faithfully their selection outputs match your project assumptions—especially around fan curve matching and psychrometric analysis. The better tools let us reuse the same assumptions across coils and schedules without manual rework.
Project assumptions and schedules control
Why it matters
Project assumptions and schedules control decide whether results stay consistent from one AHU run to the next. If assumptions are hard to capture, teams end up tweaking numbers outside the workflow.
How to check
Load a sample job and change a key input (like outside air or setpoints) and see whether the outputs update across all relevant sections. Ask where the tool stores those assumptions so you can regenerate a prior selection report.
Psychrometric analysis traceability
Why it matters
Psychrometric analysis traceability matters because coil conditions and required leaving states come from these calculations. If the tool hides steps, it’s harder to justify results in a review.
How to check
Select an example with cooling and heating, then open the intermediate results view for humidity/enthalpy states. Compare what the tool shows to what you expect for the same air conditions, and check whether units and reference points are explicit.
Cooling and heating coil sizing output
Why it matters
Cooling and heating coil sizing output drives whether selected coils match the intended capacity and constraints. Poor outputs often force rework later when coils don’t hit the target conditions.
How to check
Run a selection that includes both coil types and confirm the tool reports coil performance inputs and resulting leaving conditions. Export the selection report and verify the coil sizing values you need are visible without additional manual calculations.
Fan curve matching against static pressure
Why it matters
Fan curve matching against static pressure is what connects the airside requirement to real fan operation. If it doesn’t match how you budget static pressure, the chosen fan can drift from the design intent.
How to check
In a demo, adjust air flow and static pressure inputs and watch whether the selected fan changes accordingly. Ask to see the fan curve data and the plotted operating point, then confirm it aligns with the stated static pressure basis.
Selection report export and revision readiness
Why it matters
Selection report export and revision readiness matters when coordination cycles repeat. When exports are complete and consistent, we can audit what changed without rebuilding the run.
How to check
Export a report, then edit one input and re-export to see what updates and what remains the same. Check that the export includes the key numbers you use for review and coordination, in a format your team can reuse.
BIM object and schedule export options
Why it matters
BIM object and schedule export options reduce handoffs between selection and documentation. If exports are limited, teams re-enter data manually and risk mismatch between mechanical selections and drawings.
How to check
Create a selection and use the export function to generate a BIM object or family artifacts, if offered. Verify field mapping by changing a coil or capacity input and confirming the exported object updates the relevant parameters.
Red flags
- Fan curve matching lacks a visible operating point
- Psychrometric analysis hides intermediate air-state values
- Selection report export omits the numbers needed for review
Fit by situation
- If you routinely regenerate selections after setpoint changes, prioritize Project assumptions and schedules control.
- If your reviews depend on traceable air-state math, prioritize Psychrometric analysis traceability.
- If your work hands off selections to BIM and schedules, prioritize BIM object and schedule export options.
