HVAC Design Sample Workflow

Master commercial HVAC engineering through a real 45-story high-rise case study. 17 phases, 30 drawings, full calculations, and sequences of operations.

HVAC Workflow is a complete engineering training platform for mechanical and HVAC engineers, engineering students, and technicians. The app walks you through all 17 phases of a real commercial HVAC project from project initiation through commissioning and closeout, using the Skyline Tower Complex as a structured case study. THE SKYLINE TOWER CASE STUDY Follow a 45-story, 2.5-million-square-foot mixed-use high-rise through every stage of HVAC engineering. Each phase presents what was done, why decisions were made, how calculations were performed, and what deliverables were produced. This is not abstract theory. It is a project-based walkthrough of how commercial HVAC engineering actually works. 17 ENGINEERING PHASES Phase 1: Project Initiation and Basis of Design Phase 2: Cooling and Heating Load Calculations Phase 3: Central Chiller and Boiler Plant Design Phase 4: Airside Systems and VAV Design Phase 5: Ductwork Design and Static Pressure Analysis Phase 6: Hydronic Piping and Pump Sizing Phase 7: Outdoor Air, Ventilation, and Energy Recovery Phase 8: Smoke Control and Fire-Life Safety HVAC Phase 9: Building Automation System Design Phase 10: Data Center Precision Cooling Phase 11: Parking Garage Ventilation Phase 12: Tenant and Retail HVAC Phase 13: Energy Modeling and ASHRAE 90.1 Compliance Phase 14: Controls and Sequences of Operations Phase 15: Electrical Integration and VFD Specifications Phase 16: Commissioning, TAB, and Functional Testing Phase 17: As-Builts, O and M Manuals, and Project Closeout ENGINEERING DRAWINGS GALLERY Study 30 professional HVAC engineering drawings including chilled water system schematics, VAV duct layouts, riser diagrams, BAS architecture diagrams, smoke control cause-and-effect matrices, data center cooling plans, and commissioning test plans. Pinch to zoom, export any drawing as PDF. DELIVERABLES LIBRARY Every phase produces real engineering documents. Read full content for over 50 deliverables including load calculation reports, equipment schedules, sequences of operations, commissioning plans, TAB procedures, and O and M manuals. STANDARDS COVERAGE Content references ASHRAE 90.1, ASHRAE 62.1, ASHRAE 55, ASHRAE 135, NFPA 92, NFPA 90A, SMACNA Duct Construction Standards, IMC, AABC, and NEBB throughout each phase, showing how code requirements drive real engineering decisions. TRACK YOUR PROGRESS Mark steps and phases as reviewed. Visual progress indicators across the dashboard, workflow, and gallery show exactly how far through the engineering lifecycle you have studied. PDF EXPORT Every deliverable and engineering drawing can be exported as a formatted PDF directly from the app. Share via AirDrop, email, or any connected service.
