WSP used IESVE to help create a Central Thermal Plant for Sydney’s Central Park Development which will save 136,000t of CO2 equivalent greenhouse gas emissions over 25 years.
Located in the middle of Sydney, Australia, Central Park is a mixed-use development consisting of residential, commercial, retail and historical spaces surrounding Chippendale Green, a 6,400m2 park.
Fourteen buildings filled with offices, studios, eateries, shops and approximately 2,000 apartments sit on the 5.8 hectare property, which developers Frasers Property Australia and Sekisui House Australia aim to make into the country’s greenest urban village.
WSP, the thermal plant designer, used IESVE to create a realistic 3D virtual representation of the Central Park development. Buildings, facades, surface geometries, components (including doors and windows), shading devices and room/zone configurations were incorporated into the site model based on architectural design data. Adjacent buildings in the surrounding built environment were incorporated in order to represent overshadowing characteristics.
The geometry model was then populated with known material properties, occupancy and equipment profiles, HVAC system configurations and climate profiles, representing a realistic depiction of the Central Park Development’s thermal demand characteristics. These characteristics were then utilized as the basis for the thermal plant design to determine the optimum system configuration to match peak and daily loads.
Based on project goals and modeling results from IESVE, the tri-generation system was chosen for the central energy option, and the single Central Thermal Plant (CTP) services the entire site.
The CTP produces thermal and electrical energy, providing electricity, heating, air conditioning and domestic hot water to 14 buildings over the 100,000m2 first phase of the 255,000m2 development.
The CTP also reduces Central Park’s reliance on the grid by using engines powered by natural gas to produce electricity. The generated electricity feeds the chillers. Waste heat is recovered from the engines and warms the precinct’s water. Greenhouse gases are reduced, and the system helps the development in meeting its goal of carbon neutrality.
By using a CTP, a number of reductions in infrastructure investments have been made, resulting in 20 percent greater efficiency:
