A state of the art HVAC system, Seeley International’s Climate Wizard, has been installed at the newly constructed, 83 Pirie Street, Adelaide.
The site, which is made up of 17 levels of office space and 360m2 of lettable retail space, has achieved world class energy efficiencies and environmental standards.
With a focus on sustainability and wellness, the HVAC system had to deliver a total of 36,620 l/s of pre-cooled outside air to supply the building’s air handling units.
The project also called for seamless connection to the Building Management System allowing for automatic, continuous, safe, unattended operation of the building’s air conditioning system.
It also had to meet WELL Building Standard requirements for a Gold WELL rating.
After evaluating project requirements, Seeley International’s Climate Wizard air conditioning technology was selected as the most efficient solution.
To meet the various needs and challenges, 6 x CW-H15S Plusunits and 4 x CW-80 units were installed, delivering a total of 37,300 l/s pre-cooled, outside air into the plantroom as a plenum providing treated fresh air for the air handling unitslocated within the plantroom.
The total input power for 6 x CW-H15S Plus and 4 x CW-80 is 53.2 kW. A baseline DX system handling the total outside air heat load would have an input power of approximately 252.5 kW delivering a typical COP of 2.9.
The installed Climate Wizard system saves 199.3 kW of peak input power, which is equivalent to a 79 per cent reduction.
The resulting performance of the instillation has contributed to several highly regarded certifications, including: 6 Star Green Star Design & As-Built Certified rating, a 5.5 Star NABERS Energy rating, a Gold WELL rating as well as a PCA A Grade rating.
