Application analysis
Coordinate the water-side connection at each terminal.
Build the branch schedule from each AHU, coil or terminal connection drawing. Record water-side duty, flow, pressure differential and dimensions. Allocate responsibility for isolation, control valves, balancing devices and measuring points.
Coordinate the branch with equipment access doors, insulation and maintenance space. Define drainage, venting, supports and movement allowances. Record installation, flushing, testing and commissioning responsibilities alongside the equipment schedule.
Fan-coil distribution
Prepare a consistent but duty-specific branch schedule.
Plant replacements
Resolve the new equipment interface against existing distribution.

Engineering review
The inputs that change the design.
| Design input | What it changes | Evidence to request |
|---|---|---|
| Terminal data | Align the branch with coil duty and connection limits. | Equipment schedule, flow and connection drawings. |
| Control interface | Allocate balancing and control responsibilities. | Control-valve data and commissioning requirements. |
| Space & insulation | Maintain equipment access around the completed pipework. | Insulation envelope and maintenance clearances. |
| Movement & supports | Avoid imposing unreviewed loads on equipment nozzles. | Support arrangement and mechanical movement assessment. |

Questions worth resolving
Before the specification is fixed.
What belongs in an AHU branch schedule?
List flow, pressure differential, connection dimensions, isolation/control/balancing requirements and access clearances.
How should repeated terminal branches be prepared?
Group terminals by their documented duty and connection requirements, then record the branch arrangement for each type.
How does this page relate to Cooling & Heating?
HVAC focuses on AHU and terminal interfaces. Cooling & Heating covers thermal plant and the wider hydronic distribution arrangement.
