HVAC CFD Analysis for MEP Design Teams
Precision CFD supports mechanical consulting firms with practical CFD studies for airflow, thermal comfort, ventilation effectiveness, contaminant control, and exhaust performance.
Based in Toronto. Supporting MEP teams across North America.
Built for Consultants
CFD support when your project needs it, without building an in-house simulation team.
Many MEP firms only need CFD occasionally. Precision CFD works as a technical extension of your mechanical design team, providing focused analysis that supports design decisions, owner discussions, and project documentation.
The work is scoped around the specific question the design team needs answered: airflow direction, comfort risk, ventilation effectiveness, exhaust capture, contaminant migration, or design option comparison.
Services
HVAC-focused CFD services
Analysis is kept software-agnostic, practical, and tied to real mechanical design decisions.
Thermal Comfort Studies
Assess occupied-zone temperature, air velocity, draft risk, vertical gradients, hot/cold zones, and comfort conditions under proposed HVAC operation.
Age of Air & ACE
Review fresh air distribution, local mean age of air, air change effectiveness, and areas with poor ventilation performance.
Pathogen & Contaminant Control
Model airflow direction, dilution, contaminant migration, directional airflow, exhaust capture, and cross-contamination risk.
Exhaust & Capture Performance
Review exhaust placement, make-up air interaction, capture effectiveness, bypass paths, and localized contaminant removal.
Design Option Comparison
Compare diffuser layouts, airflow rates, supply air temperatures, return/exhaust strategies, and retrofit alternatives before final design.
Use Cases
Where CFD adds value
CFD is most useful when standard calculations do not fully describe actual airflow behaviour in the space.
Atriums & High-Ceiling Spaces
Evaluate stratification, air throw, temperature gradients, and whether supply air reaches the occupied zone.
Galleries, Museums & Performance Spaces
Assess air movement where comfort, environmental stability, and architectural constraints are all important.
Healthcare & Isolation Spaces
Review directional airflow, containment behaviour, dilution, and exhaust paths as design-support analysis.
Laboratories & Containment Rooms
Analyze make-up air interaction, capture zones, contaminant migration, and exhaust effectiveness.
Large Assembly & Office Spaces
Identify poorly mixed zones, draft risk, ventilation effectiveness issues, and alternate diffuser strategies.
Retrofit Projects
Evaluate proposed HVAC modifications where existing shafts, ceilings, equipment, or architectural constraints limit design options.
Process
A clear process for design teams
The study is scoped around the design question, not unnecessary modelling complexity.
Project Intake
Review drawings, HVAC layouts, airflow rates, loads, design criteria, and the specific question the CFD study needs to answer.
Scope Confirmation
Define model boundaries, assumptions, operating cases, performance criteria, deliverables, and timeline.
Model Development
Set up geometry, airflow inputs, thermal boundary conditions, occupied-zone criteria, and analysis cases.
Results Review
Review airflow, velocity, temperature, ventilation, contaminant, and exhaust results from an HVAC design perspective.
Final Report
Issue clear documentation with plots, assumptions, observations, and design-support recommendations.
Deliverables
Reports designed for MEP coordination and project documentation.
Deliverables can be tailored for schematic design, design development, tender support, peer review, owner review, or authority-facing supporting documentation.

FAQ
Common questions
When should an MEP consultant consider CFD?
CFD is useful when airflow behaviour, comfort, stratification, ventilation effectiveness, exhaust capture, or contaminant migration cannot be confidently assessed using standard calculations alone.
Do you replace the mechanical engineer of record?
No. Precision CFD provides analysis and design-support recommendations. The engineer of record remains responsible for final design decisions, code compliance, and professional sign-off unless otherwise agreed.
Can you compare multiple HVAC design options?
Yes. Typical comparisons include diffuser layouts, airflow rates, supply air temperatures, return locations, exhaust strategies, and retrofit alternatives.
What information is needed to start?
Typical inputs include floor plans, sections, HVAC drawings, diffuser schedules, airflow rates, supply air temperatures, room loads, occupancy criteria, and the specific design question to be answered.
Can results be used for owner or authority review?
Yes. Reports can be prepared for owner review, design documentation, peer review, or authority-facing supporting documentation depending on the project requirements.
