What it does

Everything you need for
MEP system design

AIM Works covers the full mechanical design workflow — from early feasibility to construction documents.

🧮
Thermal Load Calculations
Three fully implemented methods — Simplified, CLTD/CLF, and RTS — all altitude-corrected with hourly solar and internal gain profiles.
🌀
ASHRAE 62.1 Ventilation
Per-zone and multiple-zone recirculating calculations per §6.2.2 and §6.2.5. Auto-computed Ev from load results with DCV analysis.
🎯
AI Design Guidance
Ask Claude anything about your project — system recommendations, compliance issues, basis of design narratives, and next-step guidance with full project context.
Duct & Pipe Networks
Darcy-Weisbach pipe sizing with four hydronic topologies (direct, reverse return, primary/secondary, Hardy-Cross ring main). Equivalent diameter duct sizing.
⚙️
Equipment Selection
Rule-based system recommendation wizard, full equipment schedules, ancillary item generators, and electrical load summaries with code references.
Code Compliance
Automated checks against ASHRAE 90.1, IMC, and NFPA. Cross-discipline QA dashboard flags issues before they reach the drawing set.
📄
PDF Engineering Reports
Six-page professional reports: design conditions, zone load summary, ventilation schedule, equipment schedule, and compliance summary.
💧
Psychrometrics
Full moist air property calculations — humidity ratio, enthalpy, dew point, wet-bulb, and coil performance analysis with altitude correction.
📊
Economics & Reporting
Life-cycle cost analysis, energy cost estimates, VFD savings, parametric studies, and full CSV/markdown/JSON export for any downstream workflow.
How it works

From project setup to
construction documents

AIM Works guides you through a structured engineering workflow so nothing falls through the cracks.

1
Set up your project
Enter location, building type, and design criteria. Pull ASHRAE weather data automatically. Define zones with geometry, envelope assemblies, and internal gains.
2
Run calculations
Calculate thermal loads, ASHRAE 62.1 ventilation requirements, duct and pipe networks, and equipment sizing. Results flow automatically between modules.
3
Ask the AI assistant
Claude has full access to your live project data. Ask for system recommendations, compliance review, design narratives, or anything else — it responds with engineering-grade answers.
4
Export & deliver
Download PDF engineering reports, equipment schedules, compliance summaries, and CSV data. Everything you need for design submittals and construction documents.
