LEED IAQ Calculator
Specialist LEED IAQ calculation. ASHRAE 62.1 throughout. The Minimum IAQ Performance prerequisite and the Enhanced Indoor Air Quality Strategies credit, calculated to ASHRAE 62.1. Outdoor airflow targets locked at concept stage for the MEP design team.
What we deliver.
- Outdoor air calculation per ASHRAE 62.1 Ventilation Rate Procedure. Per zone people outdoor air rate Rp and area outdoor air rate Ra, totalled per air handling system.
- Zone primary air calculation, with occupant diversity (D) and system ventilation efficiency (Ev) applied per ASHRAE 62.1.
- Audit ready calculator output in the format USGBC reviewers expect.
See what we hand over.
Audit-ready ventilation calculations — zone-by-zone outdoor airflow per ASHRAE 62.1, totalled per air-handling system, in the format GBCI reviewers expect.
IAQ-specific FAQs
What does the LEED IAQ calculation cover?
Ventilation rate procedure calculations to ASHRAE 62.1 for the Minimum IAQ Performance prerequisite and the Enhanced Indoor Air Quality Strategies credit.
What inputs do you need?
Architectural plans, occupancy counts, the mechanical schedule and AHU-to-zone mapping. We log fresh airflow per person and per area for every zone.
How is zone airflow calculated?
People and area outdoor air rates (Rp and Ra) per ASHRAE 62.1, with occupant diversity (D) and system ventilation efficiency (Ev) applied at system level.
Does the IAQ calculation integrate with the energy model?
Yes. Same building, same schedules — the ventilation case and the energy case never disagree with each other.
Do you handle review comments on IAQ credits?
Yes. We respond through the GBCI review process and revise the calculations as required.
Can you deliver white-label?
Yes. NDA by default, deliverables in your template.
