Situated in the heart of Adelaide’s business precinct, 83 Pirie Street is building a sophisticated workplace where lifestyle and innovation are at the forefront. With a focus on sustainability and wellness, a state of the art HVAC system would be required to achieve world class energy efficiencies and environmental standards.
With 17 levels of office space, 360m2 of retail space and over 30,000m2 total area, 83 Pirie Street required a total of 36,620 L/s of pre-cooled outside air to effectively supply the building’s air handling units. With a strong focus on energy efficiency and sustainability it was important to deliver an HVAC solution that would meet rigorous standards as part of the projects certifications. 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.
After evaluation of the project requirements, The Climate Wizard air conditioning technology was selected as the most efficient solution. To meet the various needs and challenges, 6 x CW-H15S Plus units 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 units located 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 considering a typical COP of 2.9.
The resulting performance of the installation will contribute to several highly regarded certifications, including: 6 Star Green Star Design & As-Built Certified rating, a 5.5 Star NABERS Energy rating, a Platinum WELL rating as well as a PCA A Grade rating.
