Zone load schedule to Excel.
A zone load schedule is the building services calculation that ties HVAC capacity to architectural zones. One row per zone carries the area (square feet or square meters), occupancy count, sensible and latent cooling loads, heating load, supply and return airflow rates, exhaust airflow, ASHRAE 62.1 ventilation outdoor air requirement, the source AHU or VAV serving the zone, and any reheat coil reference. The zone load schedule is the airside balance worksheet the BAS engineer compares against the design intent and the commissioning agent uses to verify zone-level airflow on site.
Upload a zone load schedule or a thermal-load calculation report and extract every zone into a structured spreadsheet. Zone, area, occupancy, sensible and latent load, supply / return / exhaust CFM, ventilation outdoor air rate, and source-equipment reference all read into the columns the BAS engineer and the commissioning agent compare against the airside design.
| Audience | Uses for | Filter applied |
|---|---|---|
| HVAC design engineer | Verify capacity against architectural changes | All zones with floor-plan delta |
| BAS controls integrator | Zone-level setpoint configuration | Source AHU / VAV reference |
| Commissioning agent | Site balancing verification | Per-zone design CFM vs. measured |
| Energy auditor | ASHRAE 62.1 ventilation audit | OA CFM per occupancy density |
| Sustainability consultant | LEED EQ credits | Zones meeting ASHRAE 55 thermal comfort |

Common questions.
Does this handle ASHRAE 62.1 ventilation calculations?
Ventilation OA CFM is read as drawn from the load schedule. The ASHRAE 62.1 calculation itself (people component, area component, zone air distribution effectiveness) stays in your HVAC analysis package; the extracted schedule is the input to that calculation, not the calculation itself.
Can the airside balance worksheet feed Carrier HAP or Trane TRACE?
The airside balance worksheet exports in the column shape these tools read for zone input. Source-AHU and source-VAV references carry through so the load schedule and the airside design tie back together cleanly.
