There are only 14 Gold rating WELL certifications worldwide.

The solution uses interconnected, closed-loop cooling towers to provide unparalleled, fault-tolerant resilience.

A large fluid cooler serving the building's secondary condenser water loop was also refurbished as part of the chiller replacement program.

The KX system is an extremely versatile operating unit with superior performance and technology that makes it ideal for expansive spaces.

The cost advantage of just replacing the refrigerant and not the chiller was enormous.

While the original schematics of the buildings will not change, services inside like heating and cooling, are being retrofitted to utilise modern designs that promote sustainability.

The biggest challenge was the dimensions of the evaporator - it had to be less than two metres long.

Haier's low static indoor units measure 185mm high and 420mm deep, so it was able to fit above the wardrobe.

The facility has grown from 50 staff in 2014 to more than 1,000 arriving by the 2018 Opening Ceremony.

After installing the Danfoss electronic TX valves each system recorded an average power consumption of 30kW, resulting in an average saving of 15kW per system.

The system allows for the simultaneous generation of electricity and useful heat and cooling in a single process.

Newmason uses high thermal-load building materials with insulation in the walls, ceilings and floors.

The R744 system will run in transcritical format for only 850 hours per annum based on average ambient temperatures and will reach COPs of eight when running sub-critical.

The blend is a mix of 42 per cent R134a and 58 per cent HFO 1234ze(E) which is marketed by Honeywell as Solstice N13.

The centre covers over 13,600 square metres and is designed to scale to 25MW.

The only thing holding back a rapid expansion of Co2 refrigeration for all cooling, freezing and AC duties is the unavailability of larger compressors.
