FMG Palmerston North

FMG’s new head office in Palmerston North’s CBD is the largest Office development constructed in the city in over 25 years.

The Challenge

The challenge for this project was to design an efficient air conditioning and ventilation systems that would fit with the modern layout and design of this new purpose built office.

The Mitsubishi Electric Solution

The equipment selected for the new FMG building consisted of Mitsubishi Electric City Multi Heat Recovery Systems to serve the heating and cooling requirements, accompanied by several Lossnay Heat Recovery Ventilation Systems to meet the fresh air needs of the building.

Eight R2 Heat Recovery Systems of various capacities and indoor configurations were decided upon to heat and cool the spaces from the ground floor to the third floor. The majority of indoor units installed in the FMG Building were mid static ducted units. These units offer a wide range of five static pressure options for duct-run flexibility, and are fitted unobtrusively inside the ceiling space. Sleek, pure white coloured City Multi VFM Compact Cassettes were also installed into the smaller office spaces to fit with the modern décor.

Twenty-four Mitsubishi Electric Lossnay units were installed into the same first four floors as the VRF units. This was designed so that when the Lossnay units operate in Heat Recovery Mode, it would ease some of the heating/cooling loads from the R2 systems.

Complete HVAC systems control at FMG is achieved via an AE200 Central Controller with expansion modules, allowing it to connect to all 107 indoor units, and a DIDO Interface.
