- Common in mid-size Class A and APAC trophy buildings.

# VRF system

*MEP · APAC*

## Short definition

Variable Refrigerant Flow — multi-zone heat pump cooling/heating.

## Full definition

Common in mid-size [Class A](/glossary/class-a) and APAC trophy buildings. Highly efficient zonal control; lower infrastructure cost than chilled water systems. Maintenance complexity increases at scale.

## Why this matters for Class A leasing

VRF system is part of the mep vocabulary that institutional Class A occupiers, landlords, and advisers use across APAC markets. Understanding it correctly affects how you read lease documents, model occupancy economics, and benchmark deal terms across cities. Class A Atlas tracks the APAC definition alongside the global standard so [cross-border](/topics/cross-border-expansion) occupiers can translate quickly.
