BPMS / BPMS Equipment Sizing Builder
Manual S software for HVAC equipment selection
BPMS Equipment Sizing Builder
Manual S equipment selection software for comparing HVAC and heat pump performance against reviewed Manual J heating, sensible and latent cooling loads.
Built for field-to-report workflows
Compare equipment data
Evaluate candidate performance against heating and cooling requirements.
Document the selection
Review flagged conditions and continue with the selected airflow context.
What you can do with BPMS Equipment Sizing Builder
Start with reviewed design loads
Bring heating, sensible cooling and latent cooling requirements into the equipment review. Preserve the design-condition context rather than choosing solely by nominal tonnage.
Manufacturer performance inputs
Document equipment models and performance data for the relevant outdoor and entering-air conditions. Source data quality matters when comparing candidate systems.
Cooling capacity review
Compare total, sensible and latent performance with the project requirements. Review capacity balance and moisture-control implications before making a selection.
Heating and heat pump review
Evaluate heating performance at project conditions and review supplemental heat where relevant. Keep equipment assumptions and application limits visible.
Selection notes and review
Record candidate information, source references and review decisions. Resolve missing inputs and flagged conditions before treating the selection as ready for downstream use.
Continue to duct design
Use the reviewed equipment airflow and design context in the duct-sizing workflow. Revisit the duct design when equipment or airflow assumptions change.

Frequently asked questions
How does Manual S differ from Manual J?
Manual J calculates the building's heating and cooling demand. Manual S selects equipment using those loads together with manufacturer performance at the design conditions.
Can nominal tonnage replace detailed performance data?
No. Nominal tonnage does not describe all sensible, latent or heating performance at the project's conditions. Review the applicable manufacturer data.
Can I evaluate heat pumps?
The equipment workflow supports heat pump performance review against project heating and cooling requirements. Confirm the manufacturer's operating limits and any supplemental heat assumptions.
Does this page claim ACCA certification?
No. BPMS supports Manual S equipment-selection workflows; selections require qualified project review and appropriate manufacturer source data.
