Part of the Carlaw Park Site re-development.
The specification provided by Thurston Consulting Ltd clearly required a VRF solution. While Mitsubishi Electric was nominated as the supplier the specification itself was performance specified; it was up to each contractor to submit their design kilowatt selections and unit quantities. This meant ensuring each offer complied with the specification and was also a cost effective workable system. There were a number of tenancy fit outs to be completed as part of the build.
City Multi R2 heat recovery systems were used throughout the site.
G50 central controls with umbrella TG2000 for overall control, energy management and maintenance operations were selected along with a BACnet interface to BMS.
Ducted indoor units used in most offices areas giving some flexibility to tenant fit out as the buildings became let. Rolling commissioning during the project allowed for a stress free hand over on time at the completion of the project with all systems meeting the performance criteria of the specification.
All condensing units were roof mounted to minimize ground level noise and visual impact.
