Tagsight for hvac and mep engineers
Building services run on schedules across four trades - HVAC equipment, duct, plumbing fixtures, electrical lighting - and the schedules diverge between disciplines the second the floor plan revises. The HVAC engineer doing zone loads and the architect adjusting the partition layout are two people who should have agreed on the room boundary and didn't.
What you do today.
- Transcribe the HVAC equipment schedule, duct schedule, and zone load schedule from the design drawings into the BAS controls package
- Cross-reference VAV tags against the duct schedule and zone load calculations on every revision
- Maintain a parallel tag list for the BAS points (DDC) separate from the HVAC equipment schedule
- Re-do all of the above when the architect issues a new floor plan and the zones move
What changes with Tagsight.
- Upload the mechanical drawing set, get a structured HVAC equipment schedule with capacity, supply CFM, return CFM, and BAS point references per row
- Pull the duct schedule with size, run length, fitting count, and zone reference off the same pass
- Get a zone-load schedule scaffold tied back to the HVAC equipment row that serves each zone
- Filter the controls point list (BAS DDC) out of the HVAC equipment schedule for the controls integrator hand-off
- Read NEN, ASHRAE, SMACNA, and house tag conventions as drawn - HVAC tagging varies more by firm than process tagging does
Where it fits in your week.
Commercial HVAC retrofit
Existing building HVAC schedule lives in a 1998 binder. Pull the binder and the new design drawings through extraction, surface what changed (new VAVs, repurposed zones, retired equipment), hand the change list to the BAS commissioning lead.
Datacenter cooling commissioning
Datacenter scope ships with a CRAC/CRAH schedule, a chiller plant schedule, and a dual-path airside schedule. Extract once, filter by service, hand each discipline the slice they own.
BAS point list extraction
Controls integrator needs the BAS DDC point count off the design drawings before the bid closes. Run the HVAC equipment schedule and the controls drawings, get the point list filtered to AI / AO / DI / DO per the same ISA convention process plants use.
FAQ.
Does Tagsight handle ASHRAE 135 BACnet point naming conventions?
BACnet object names appear as drawn in the controls point list extraction. BACnet object instance numbering is a runtime assignment in the BAS configuration tool, not a drawing field; the extracted point list is the input to that step.
What about Dutch HVAC drawings using NEN tag conventions?
Yes. NEN Dutch HVAC tag dialects and KKS-style hierarchical tagging read as drawn. The standards corpus includes ASHRAE 90.1, SMACNA, BACnet (ASHRAE 135), and NEN; HVAC drawings route through the same P&ID-shaped pipeline that handles process plants.
Can it tell apart HVAC instrumentation from plumbing fixtures from electrical lighting fixtures on a combined MEP set?
Yes. The doc-type detector routes HVAC drawings, plumbing risers, and lighting schedules through dialect-specific extractors. A combined MEP set processes as separate per-discipline workspaces under a parent project, so each trade's document set stays clean.
