Large-Scale VRF Rooftop Installation

A multi-tenant commercial complex needed a unified climate control solution that could serve diverse tenant needs — from office spaces requiring quiet comfort to retail areas needing high-capacity cooling — all from a centralized rooftop installation.

We deployed a large-scale VRF system with multiple outdoor units on the rooftop, connected to dozens of indoor units throughout the complex. The system uses heat recovery to transfer excess heat from cooling zones to zones requiring heating, dramatically reducing energy consumption.

System engineering and load calculations, rooftop structural assessment, multi-unit VRF outdoor equipment installation, refrigerant piping throughout the complex, indoor unit installation across all tenant spaces, centralized controls with tenant sub-metering, and full commissioning.

Energy costs were reduced by 40% compared to the previous conventional system. Tenant satisfaction scores improved across the board, with individual zone control allowing each space to maintain ideal conditions. The centralized monitoring system enables proactive maintenance and rapid issue resolution.
