Equinox House is prime office space in the centre of Wellington City, located on Lambton Quay’s Golden Mile. This building backs on to The Terrace where Equinox IT houses their Wellington-based staff.
The client required Level 1 of the building to be modernised, including full replacement of the heating, ventilation and air conditioning system while maintaining occupancy on the remaining floors.
There was a need for an efficient system capable of simultaneous heating and cooling while observing client comfort and maintaining the exposed nature of the services while minimising the risk associated with refrigerant concentration issues. Therefore, the design and build contractor, Advanced Building Services, pursued a hydronic solution.
During the design phase there was limited space for outdoor plant with exposure to moderately salient air where corrosion issues were identified, leading to a requirement for a modular arrangement.
The Mitsubishi Electric Hybrid VRF System met the client's brief by providing an effective and comfortable air conditioning system in a cost and time effective manner. This allowed for the building and modernisation works to be undertaken in the timeframes given while also meeting the client’s budgetary requirements.
Due to the limited space available for outdoor plant, coordination of structural building elements and space required for maintenance and access demands, the PURY-YNW-A-BS was perfect for this application. This solution also accounts for the building’s marine location with factory-applied marine corrosion protection of the outdoor unit components.
