The developer wanted the entire rooftop free for revenue-generating open-air cafes and seating, ruling out conventional top-discharge VRF outdoor units. ERATEC proposed Hitachi's compact, side-discharge SideSmart™ system, mounted on a dedicated rear service catwalk instead of the roof.










The catwalk-mounted SideSmart™ installation covered 100% of the internal retail cooling demand — 171.2 TR — while freeing the entire rooftop for commercial hospitality development.
