An HVAC choice shapes more than the equipment budget. It affects apartment layouts, building utilities, resident comfort, and the work required to operate the property. Comparing workable systems early helps developers see those effects before space and infrastructure are committed.

*Relative initial-cost ranges are directional. Actual costs vary by climate, building size and configuration, ventilation requirements, local labor, utility capacity, and market conditions.
Understand the Building Impacts
Compare HVAC options for the same building. Look at how each affects construction costs, rentable space, infrastructure, resident comfort, and ongoing operations. A lower installed cost may come with trade-offs elsewhere in the property.
Saving Space Can Shift the Problem
A smaller unit closet may free apartment area, while equipment, ducts, piping, drainage, and service access still need space. Check where those requirements land, in ceilings, shafts, exterior walls, or shared areas, before treating the closet reduction as a rentable-area gain.
Saving space in one place can consume it somewhere else.

Evaluate the Trade-Offs Earlier
Evaluating HVAC options early can help developers protect rentable area, control utility demand, and avoid costly changes later.
BASE4 evaluates those trade-offs across the disciplines they affect:
- Architecture, structural, MEP, and interiors under one roof
- HVAC options evaluated against space, utilities, and building infrastructure
- 100% Revit and 3D coordination to catch conflicts earlier
