Situated on the Wellington Waterfront, the Museum of New Zealand Te Papa Tongarewa is a major icon in the capital city.<\/p>

The impressive building, designed by Jasmax Architects, sits on 152 base isolators and is designed to protect occupants and collections from a one in 2000 year earthquake. Since opening in 1998, Te Papa has seen visitor numbers of around 1.5 million annually.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

The central chilled water system in Te Papa was nearing end of life, with the chillers and cooling towers due for replacement. The original chillers utilized an obsolete refrigerant and were inefficient in comparison to modern chiller technology.<\/p>

The client\u2019s goal was to implement a chilled water system that maximized energy efficiency, reduced operational costs and provided an upgrade path which allowed for future transition to new lower global warming potential (GWP) refrigerants such as 1234ze.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

A key challenge for this project was to provide two new high-efficiency chillers with a combined cooling capacity of 4000kW, while also lowering the pump power requirements of the system. In addition to this, the new plant needed to minimize the cooling tower water use and reduce legionella risk. The project also called for a chilled water plant optimization solution to ensure this solution operated at the maximum achievable efficiency.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

zAs the building was still occupied during the revamp, the central plant needed to be upgraded and the optimization system integrated with the existing site building management system (BMS). Therefore, a collaborative approach towards commissioning and system fine-tuning was required while making sure the day-to-day running of this busy museum wasn\u2019t impacted.<\/span><\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
