The new system is controlled by the artificial intelligence (AI) management system PlantPRO, which uses machine learning technology to collect and analyse data and make real-time adjustments to provide the centre with the most energy-efficient air conditioning.
The system is expected to reduce electricity consumption by more than 30% compared with the existing seawater-cooled chiller plant, equivalent to a reduction of 370 tonnes of carbon emissions a year. CLPe is funding, designing, constructing, operating and maintaining the new system, while the Shui on Group will pay a monthly service fee throughout the 15-year contract period.
Meanwhile, CLPe is working with Chinachem Group in a 20-year partnership to bring the first zero-carbon chiller system of its kind to Hong Kong. Under a Build-Own-Operate-Transfer agreement, the old chiller plants at Nina Tower – the tallest construction in the New Territories – will be replaced with an AI-controlled water-cooled chiller system, and the electricity consumed will be matched by an equal amount of Green Electricity Certificates linked to a CLP Holdings’ renewable energy project.
The new air-conditioning system at Nina Tower will reduce electricity consumption by over 50% compared with the existing system, equivalent to 7,000 tonnes of carbon emissions a year.
